Sport Nutrition and diet myths

Sport Fitness
Ok this is where I make myself really unpopular. But in fairness to any who look at this and think I am saying you are doing something stupid consider I have likely made most of these mistakes myself during the decades I have trained, so what I am intending to do is help you avoid some of them without learning from your own mistakes.

Number 1 Protein the wonder food
Lose weight with this low carb high protein diet, gain mass with this high protein diet, anyone see something a bit strange here?
Protein is good for you, so good in fact that cutting it out of your diet will result in your death, but in fairness this is also true of carbs, fats, vitamins, minerals and even arsenic based on one set of research. However as is likely easier to understand with arsenic than protein eating too much of it will cause damage in your body so excess has to be removed or made useful.
Free form amino acids are toxic to the body, the only reason the body breaks proteins down to this level is for transportation, in the same way as you buy a flat pack kitchen to put in the back of your car because having it fully assembled would mean it won't fit. If they are used rapidly the body suffers minimal damage and everybody's happy. However if this is not used up the body has to take action. We haven't survived evolution by being too wasteful so the first thing we will do is convert whatever we can to energy as lipoproteins which are a form of fat, the rest is converted to urea for safe removal through our urinary system.
But these systems work, especially short term, so how does it happen? I will take these one at a time.
Low carb high protein diet to lose weight. Something many people tend to forget even though we all know it, water is heavy. Getting rid of the excess in your urine means losing one part protein nine parts water, that is how much it takes to remove this potential toxin. So for a while the body is so busy stripping you of water that you lose pounds while the body is actually locking away more fat in form of lipoprotein. It is also so busy being lethargic due to lack of carbs that you don't notice the effect of dehydration as much. This can only be short term unless you start balancing out your diet better or are burning off the additional fat being stored with exercise.
High protein for mass gain. By simply adding protein to your diet you will not notice the drop in water weight as much and most after mass will be thinking longer term so only notice the upturn when the body replaces the water and the additional weight from newly stored fat is assumed to be lean muscle.
The contradiction. With everything I have just said this will seem strange. If you are training try to take in a tiny amount more protein than you strictly need. The additional metabolism and tissue repair will require more protein for rebuilding everything from enzymes to new cell tissue, covering muscle to fat containment cells. If you have enough intelligence to be questioning you will wonder why would slightly more than you need be good if excess is so bad. Too little leaves a deficit and that could be detrimental to your health or stop you gaining that extra bit of muscle you have worked so hard for. Much as I painted an accurate but dramatic picture of what happens to excess protein, this is only an issue if there is a lot of it, the body will happily burn off a few grams of excess and dispose of a few more of urea without causing you any issue at all.
In summary protein good, too little bad, ideal perfect and if you get it sing it from the rooftops as an all hail miracle, little bit too much is as close to perfect as most of us will get and more than that is a rout to carrying more fat and making the body work too hard on waste disposal. No-one can tell you exactly how much is perfect for you but there are some good guidelines based on activity and bodyweight but simpler balance will be covered later.

Supplements are key. To ensure I got this right I went to dictionary.com to get a definition of supplement this is number 1 something added to complete a thing, supply a deficiency, or reinforce or extend a whole.
Basically if your diet is in need of supplements it is deficient, therefore before you reach for the shiny package with a body builder and bikini model on the front showing off their pearly white teeth, go to the library or search on the internet for independent nutritional advice, people like Anita Bean are a good example, nutritionist for the British Olympic team, used to dealing with everything from weight lifters to marathon runners and not gaining any financial reward for telling you to buy Joe’s latest mega super duper formula.
Perfect diet is not always easy and a just in case top up can be good, I still tend to use multi-vits and minerals because I concentrate so much on the calorific intake and balance in that area that I am not sure I get all of the trace details right, and I know city living etc. can all have an impact on how much of these you use. However this should always be the last consideration not the first as for many and it is always worth considering the potential damage of taking in too much of whatever you are supplementing with. Supplements are the lazy option and as someone who is largely against them but still uses some I say that from the heart. If I spent more time on my diet I wouldn’t bother with the pills.

Carbs are bad. No idea where this came from but somewhere along the lines carbohydrates became public enemy number one in the diet world and this looks unlikely to change.
The argument I hear in defence of this is that excess carbs become fat, this is totally true, but equally pointless as an argument. Excess protein is either converted to fat or disposed of, it cannot be burned as energy without being converted to something else first, fat doesn’t need to be converted at all and is the very thing people are wanting to avoid but it still seems to be silver medallist in worst foods race.
Carbs can be burned before conversion and are the preferred form of energy for most activities. So before you run screaming away from that loaf of bread consider the following.
Evolution and biology, no you haven’t just switched forums by mistake, but this is the main reason you shouldn’t avoid carbs. We have spent millions of years evolving for a diet high in complex carbs, our very survival has been made possible by our ability to make this our main staple food, because it is so abundant and such an effective fuel. Our saliva contains more amylase than any other primate, this is the enzyme that converts starch to glucose, showing we are designed for a diet high in starch, our insulin driven glucose management system is one of the most forgiving in nature showing we are set up for a diet of mixed carbs. Our entire dietary system has been purpose built for a diet with carbohydrate as the main caloric ingredient.
So off to the shop for a box of glazed doughnuts then! Not really, there is a catch and it’s a doozy. Our insulin supply system is forgiving but we are breaking it so often that type two diabetes is the fastest growing health problem in the developed world. Carbs are loosely grouped in two groups simple and complex, simple being everything from glucose (the thing all energy is finally broken down to) to fructose at the more complex end, and complex is basically starch. We are set up for mixed carbs but at least 90% should be complex, and ideally closer to 95%. This becomes a problem in a world driven by taste buds more than survival, sweet food tastes nicer than the bland starchy food, and therein lies the problem. So much of our food is now high in sugar without us even realising that keeping this balance takes conscious effort. Pasta is made of flour and water, with maybe a hint of egg, spinach etc. On its own wonderful, add that pasta sauce which is 30% sugar and all of a sudden you have an issue, or buy a pasta salad that comes with an even worse sauce, you get the idea.
Summary carbs are your friend as long as you are sensible. The boring starchy stuff is better for you and what you are designed to eat, sweets should be a hint not the mainstay. Yes too much carbohydrate will make you fat, same as too much protein or fat.

Healthy option foods. Just because it says healthy choice or low fat etc. doesn’t mean it is good for you. I saw a pack of flying saucer sweets advertising themselves as over 99% fat free, if you think eating a ton of these is a good idea you would have missed the over 90% sugar part.
To show how messed up this can be, full fat milk is considered bad, it contains 4% fat. Now think about how large the type would be on a diet product that was 96% fat free.
If you look at the big label you will think these are wonder foods and eating healthy is expensive. Look at the main ingredients and you will often find some of the cheapest food types around and realise eating healthy is simpler than people make out and remarkable low priced.

The KISS system, keep it simple stupid. There is so much info out there, eat x grams of y for each kg of bodyweight if you do z minutes of $ intensity activity a day or lose ^% of the benefit from your training and damage your unconceived child.
This will come as a shock to many but we have survived millions of years despite getting diet wrong most of the time, because overall the balance has been within acceptable boundaries. Ironically today with food so easy and convenient we are in one of the worst periods of global human malnutrition in history. Much of this is due to blatant disregard but I would bet that a significant amount is from people trying to eat well but failing due to sheer information overload, says me at the end of this massive post.
Regardless of race, creed, colour or gender we are all human and subsequently need roughly the same balance of food and if we are used to getting what we need and our needs change due to training etc. our bodies will let us know and even direct us to the foods we need to eat, most of the time.
There are numerous simple systems out there to use as a rough guide, but remember they are just that rough guides, to be tailored to your lifestyle. The food pyramid is one, but rather than looking at x servings of y and a further a servings of b look at the proportions and figure out your own servings. I eat a tub of rice with some eggs at work because it is simple and easy to prep, there are no vegetables or fruit there but I cover that later in the day. The rice isn’t one serving because that would mean making the number I needed would stop me being able to sleep with volume of food I would need, it may be 2 or 3 or even somewhere between, I don’t know or care. Suffice to say over the course of most days my diet is roughly in the right proportions and the food I eat is simple stuff.
If you need something more detailed consider the proportions of caloric intake in a well balanced diet are 60-65% carbs (with only 5% or less of this being sugars), 25% fats and oils, 17.5% protein. The balance is affected by activity etc. but remember so is your overall caloric need so the percentages change remarkably little. The two most who do understand nutrition to a reasonable level want to swap are fat and protein seeing the idea of 1 in 4 parts of their calories being fat as too high and fixated on giving protein more pride of place. Remember fats and oils include all cholesterols including the high density stuff which is good for you, fish oils, and everything else that comes packed with minerals and micro nutrients, and of course excess protein will become fat or waste anyway.
Increasing body mass means increasing everything you eat not one thing extra but more of everything in balance. Losing weight is the same but in reverse, not cutting out one food, unless you eat a pound of lard for breakfast, but cutting down all round. People don’t like the thought that diet can be this simple but it is.

Last example fad foods. Rocky ate raw eggs and is massive, I’ll do that, Viccy Beckham eats 2 pounds of celery a day and can fit through a letterbox I’ll do that. I don’t know anything about Viccy except she has less figure than a pool cue but you get the idea.
Raw eggs is a great one, I remember people taking it a step further and removing the yolk because it contained fat. What makes this really stupid is that the same process that made us so perfect for high carb diets, evolution, has made birds lock the protein down in the egg white to ensure it doesn’t’ go off before the chick needs it, the enzyme needed to break this in raw form is in the yolk, the only other way to make it digestible is to denature the protein by cooking it.
When you look at many fad foods you will find that most serious trainers have been eating the stuff for decades, oats are back en vogue at the moment either whole or as extracted parts, I and most have been eating them and known how great they are for years.
Bread and chocolate has been good for you then bad, back to good and will continue to yoyo forever. Simple explanation every food in the world is bad for you and most food is good for you, the key is balance. If you love chocolate, but desperately want to fit into that slinky dress without help from the all in wrestling team, have some but make it a few peeled swirls that are allowed to melt on your tongue not an entire king size box every day.
As much as practical ignore the fads, wait until real research comes out from independent sources and eat what you enjoy in balance.

Wow that's huge, I need a snack.
 
Good, common sense information here. It astounds me how far of the sensible track marketing and food manufacturers have taken the western world in terms of nutrition and just basic calories. Rather frightening to me the amount of research and money those companies have put into finding the perfect combination of sugar/fat/salt to keep us eating and eating and eating until we are full, but not satiated. And since our bodies don't get what we need in terms of nutrition, we start eating again in a vain attempt to get some nutrition.

One of my favorite books is In Defense of Food by Michael Pollen. To paraphrase a good line: be the kind of person who takes supplements, but save your money. His point was that the kind of people who take supplements tend to pay attention to their diet, they eat lots of veggies, some fruit, and overall try to focus on whole and unprocessed or minimally processed foods. I eat that way, but I also take a few supplements just to be sure... actually in part it's that I'm not that big, and despite being active on a daily basis, I do work at a desk job so my daily calorie intake just isn't that large and I want to be sure I get what I need.

The whole protein powder thing makes me crazy, particularly when I see athletes talk about 'eating clean'. So what is protein powder but a highly processed macro-nutrient? Just eat something real, there is nothing tricky about that, and the cost for real food with protein is far less than any protein powder (not to mention some of the scary chemicals from processing that have been found in many powders).

So many who are looking to lose weight go super low carb and right away lose 6-10 lbs. They don't realize until they try and do some activity that the weight lost constituted their body's stored endurance - 6 lbs of muscle glycogen bound up with water, all gone.

Our bodies tolerate an amazing range of diets, but really do best when we stay in the middle of the path. Yep, that dreaded moderation! Moderate fats, protein and carbs keep us running strong.
 
Great read, man. I'm with you on a lot of these points. I could type out an extensive post with points in agreement, but it's 7am and I haven't had my coffee yet :)
 
Last night I saw a "revolutionary" video on youtube telling athletes to eat fruit and vegetables instead of drinking coke. Sad thing is, a lot of people actually need to be told that. I'm a but cynical here and generally expect that if you need to be told to put down the coke and pick up some real food, the person advising you is probably wasting their breath. This coming from the hypocrite who consumed at least 2 gallons of coke between Saturday and Monday just passed.

I like the recommendation of a 60/20/20 split of macro-nutrients for those of us who do a lot of physical activity. My attitude towards those who aren't using their carbs is that they should probably be consuming less of them (assuming everything else is in order nutritionally and that they aren't realistically going to be increasing exertion any time soon), so perhaps more of a 50/25/25 split. Anything more low-carb than the zone diet* (40/30/30) or <100g CHO/day is probably asking for trouble if it's kept up long term; but then, in saying that, eskimos have lived on diets of almost exclusively meat and fat.

* The fact that the zone diet has a name is, in itself, a warning sign. 'little d diet' is a way of eating. 'Capital D Diet' is a way of not eating, and as a general rule, Diets (not diets) tend to have nutritional problems in them, or just plain bad ideas (although I can think of Diets that are still better than how the average westerner eats; that doesn't make them good, it just makes them less bad).

I'm still a fan of people who do strength training going for the conventional rule of thumb 1g/lb/day of protein, largely because of this: To sum up what's covered here, the studies in the meta-analysis show a significant difference in results when there's a significant difference in protein intake and don't show a significant difference in results when there isn't a significant difference in protein intake (ie a study comparing results from consuming 60g protein per day vs 70g protein per day won't show a significant difference; a study comparing results from 60g/day vs 120g/day will), and across the range of studies, 1g/lb/day seemed to be the sweet spot. 1g/lb sort of confirms some bodybuilding/fitness industry beliefs, and also challenges others. It's not low protein by any stretch of the imagination, but it's not particularly high protein, either. The food pyramid has been revised a few times over the years, but the version I'm most familiar with suggest 2-3 serves of solid protein, 2-3 serves of dairy, and 6-11 serves of cereal/grain. In my experience (which is limited, because my taste buds haven't evolved much since the second grade), dairy and grains tend to work out to be about 5-10g protein per serve, and solid protein foods about 15-30g/serve. At the lower end of those guidelines and averages, we're looking at 60g protein per day, which is more than the healthy nutritional minimum requirements for most people. Using the same doses but of more protein-rich varieties from each food group, that's 120g. Start increasing the servings, and it easily adds up for anyone who weighs 100-200lb. What this doesn't support is the fitness industry's love of supplements. I've seen a lot of people getting into fitness and consuming 150g whey/day. To put it into perspective from my own life, I've bought a total of something like 1600g of protein powder in my life, which turned out to be about 3 years worth.

I'm particularly interested in the quality of the food being consumed. This goes back to what you were saying about simple vs complex carbs, but applies to other things as well. I'd recommend people get most of their simple carbs from fruit and dairy, and then get the rest of their carbs in complex form, which is found in fruit, vegetables and grains. Go for colour when it comes to fruit and vegetables, as colour is a sign of nutrients. Go for a variety of colours, and for depth of colour. Get fat from good sources more than bad sources. For a while it's been thought that the less saturated a fat is, the better, although there's been a shift in recent years in some groups towards being more lenient with saturated fats. I'm yet to encounter many arguments for trans fats.
 
I always find these 'revolutionary' ideas brilliant. Fruit is better than soda, how did they work that out? Next they'll be saying drinking water is better than eating 2kg of lard a day!
Regional diet is always a bizarre area. Eskimos etc. so much so that they are being researched to find out what their bodies do differently to ours. The findings are quite dramatic and show that they have had to adapt to their diet over hundreds of years. Life expectancies are still not high on modern standards.
I also love the way we assigned our values to show them as savages historically. The shock as they ate raw meat, leaving out that the nearest thing they could burn was in a different country. Aboriginal being critisised for not bathing when they were just about finding enough water to drink, and that was at a level which would kill us.

Diet is incredibly simple and complex at the same time. Balance is easy on nice little diagrams and we have so much food around us that it should be a breeze. Reality is that the balance gets knocked out of kilter by different forms of activity, and most of our food isn't what we expect, so what should be easy becomes frustratingly difficult.
If you look at different packs of oats you will find different nutritional values. The quality, source location, harvesting and treatment style all have an effect. So some will be higher in carbs, others in fibre etc. Buy a prepared pack of oats and it's anyone's guess.
Many people who think they eat cleanly are shocked if they really start checking. Things sprayed on crops affect the way they grow and nutritional value. Organically grown crops from low grade seed will not be as healthy as some high grade seed grown non-orgnically.
Once the food has been harvested it is rarely sent to store as it is. Often it has to be stored for some time in temperature controlled environments to await demand and that doesn't make it look nice, so a bit of wax polish spray is called for. Once removed from the controlled environment they will start degrading faster than truly fresh produce. If in doubt take an apple from the supermarket and one from a tree, hold them in the steam of a kettle one will mottle the other won't. the mottling is wax. This is not harmful or they wouldn't be allowed it but when we buy a bag of fruit we expect to be buying something fresh and wholesome and often get at least a bit of deception.
There are a host of other tricks, additives to meat to make it hold water and weigh more, usually containing salt, being just one.
Any of us thinking we know exactly what we are eating will be kidding ourselves, simple, unfortunately inescapable fact.

Why does this matter? It's been regulated and deemed acceptably safe so no big deal. Unless of course like me you try to monitor your diet based on a balanced pyramid, not the x servings of y style, just majority starchy staple, followed by fruit and veg then meat and additives should be minimal. Simple and if you can govern your intake this way it's safe and generally healthy. However if products aren't what we expect this balance is thrown totally out of whack and our nice balanced graduated pyramid starts to tip.
One of the most recent examples I remember was buying some dried cranberries to cover a bit of the fruit side. Dried fruit in itself is not as great as fresh I know but as long as it isn't messed with it's not too bad. However when the volume of cranberry is around 60% and the rest is sugar and vegetable oil it's dreadful.

The very reason so many myths around diet have been able to bloom is that people are eating badly in general, even when they aren't meaning too. This makes them assume that they need to detox etc. while what we genuinely need is a bit of simplicity and honesty. None of us will check every pack and have calculators at the ready to be sure we are gram perfect and that's not a bad thing. The problem is that even when trying to eat simply from basic ingredients we still don't always know what we are getting.

There are a lot of things we don't know about nutrition, volumes of different fat types our bodies can work with, how effective our body is at converting carbs to glycogen so how important the GI really is for us etc. Do what you can to be sensible, accept that you will make mistakes and learn from them, or even better learn from someone elses.
 
Ohhh soda. I haven't had any kind of soda in over three years, and there are days when I would kill for a nice, cold fountain Coke haha

I'm with you there. I rarely indulge, but every now and then when I'm feeling particularly out of whack after a really long endurance fest, a Pepsi will fix me up quicker than any amount of 'quality food', bad food, or even electrolytes. Not really sure why... So, once a year after my annual 50 miler, I figure I've earned it and don't worry too much about it since the rest of the year I am eating my fruits and veggies!
 
Oh, I loved this one: Once a week, overload the body with carbs so the metabolism doesn't get lazy.

Figuring there is usually some nugget of reality buried in junk like this, I've been trying to figure out what could possibly have been intended and I just don't see it.
- Sugar rush to supercharge the metabolism?
- Quickly layer on some extra belly fat since it is metabolically active (thus not lazy)??
OK, it's just stupid and a waste of time to even think about it, but...
 
Nothing wrong with treats. In balance there is very little that isn't either good for you or well within tolerance of the bad for you.
Most bizarre medical paper I ever read that showed why they make sure survival food comes from natural sources not a lab. They produced food that was pure carb, aminos, fats, vitamins and trace minerals, to save weight. Will have tasted dreadful but not the issue. After a few weeks living on this the test subjects were becoming increasingly ill and the test was called to a stop. The area of the lab that they all headed for had arsenic in it as the only thing not in the food stuffs they were using. Obviously it's one experiment and the volumes we require even if this is taken at total face value are beyond miniscule, but this means we need at least a trace of arsenic in our diet, maybe just to have a toxin to fight off, who knows. This is in our everyday food because it is pulled through from the soil and we likely get far more of it than we need, so don't set up a business case for selling arsenic supplements.
What I liked most about the paper was the final conclusion. We don't yet know everything we need to about the bodies nutritional and environmental needs, so need to trust nature to provide what we neither realise or understand. I like how little we know, it means there is still so much to learn.
One of the people I knew constantly reminded me that her father said eat a bit of everything, got to eat a bit of dirt before you die. The irony that his statement is probably better than a number of recommended diets people pay a fortune for.
 
Actually, I just finished a book called Kitchen Literacy. It is a history of sorts about how we think about food and why we eat like we do in the west. So a long time ago before most of the population was drawn to towns and then cities, we grew what we could, traded with neighbors for some things, bought a few things, and ate a lot closer to nature in that we were eating what was seasonally available or that we had managed to put aside/dry/preserve. As people moved into towns and food was brought in, we started edging away from that up close and personal relationship with food. The bigger the cities, the longer distance the food sources, and the less we knew - so people who shopped started looking for clues to freshness and spoilage. Bigger cities and more mechanization brought foods from farther away, and eventually brought us canned foods. Then preservatives and pesticides arrived and that changed what was available too along with what was in the food. With additives and packaging, our ideas about what was good to eat changed radically. Then science shows up with the notion of calories so we (as a general population) started focusing on bang for the calorie buck (note - no notions of the macros at this point, nor vitamins/minerals. etc).

Anyway, as we learned more about components and preservatives and chemistry, it all played a role in changing what we ate and what we thought was good to eat. So did marketing and advertising. In fact, people in the early 1900's were encouraged to learn about food and good brands via reading magazines and advertisements. Of course, we have never really stopped that practise.

It was interesting to get a sense of how we have come to think about foods, food packaging and preparation, and about dietary recommendations and how those are established (politics - grrrr). And I learned a lot about how my mother-in-law got to where she is as a cook (yikes!) and about how her notions about food were formed - these have always been a mystery to me as they are so different from my family's notions.

I am convinced the journey continues. What we think is good and essential now is certain to change some more as we learn more, but I also have a strong sense that we could well head down some dead ends and over some cliffs nutritionally. I cited Micheal Pollen in an earlier post in this thread and I will again as I agree strongly with his notion that food should be something one of our not too distant ancestors would recognize as food; the rest of it is food-like substances that should mostly be avoided.
 
Great Read!!
But to be frank, I'm really curious about my health and fitness and for that I used to avoid fatty foods, snacks, shakes, sweets etc but on the other hand I used to take milk and as a regular diet which keeps me healthier, I regular used to go for a morning walk etc, I think to live our life healthy and fit we must take a very good care of our self's.
 
This article i found explains how fast-food chains doesn't really helped anyone to eat less calories:
