Sport fats in the evening.

Whats the science behind the theory of eating carbs and protein in the early parts of the day and fats and protein in the later part of the day?
 
I think it's pretty limited and I doubt there is any scientific conclusion. I think some observations point towards how eating fat in the morning will impair your glucose tolerance for several hours. If this is true, then it might be better to have carbs in the morning and fats in the evening.

I read something about it on t-nation a while back,

but when I checked the references it was rather sketchy.. I think there was some animal in vitro lab stuff.

I would think its part of carb-cyling or a high protein high fat diet. Protein and fat make you fuller and you limit your carb intake so that the body switches to fat for energy. Is this what you had in mind?

I personally haven't read any conclusive findings, Mr. Lewis. In then end it works out in a 24 hour period, is the general consensus among persons I respect, though there are values (of good) given to macro timings in certain instances.

Here is a wealth of information on Protein:



And on Fats, and including the Carbohydrate/Fat controversy (as some still believe that at certain "timings" this is not a good combination, and Lyle McDonald talks about this, and his belief on whom heightened its popularity (Dr. Berardi):

Most of the ones who were big proponents of that theory have backed off of it. I eat PB before bed. YUM.
Worry more about your whole day and less about the last few hours. :)
 
Cheers guys. Its not for me. I'm bulking and try to eat my macros as evenly as poss. A friend asked me to help him plan his diet and i automatically told him to eat fats in the evenings and carbs in the morning.
He asked why and i was like 'errrr... i dont know'

I'll tell him to scrap that idea.

I think its prob one of those placebo effects... if you are trying to eat specific things at specific times of the day, then your going to be paying more attention to what you eat. I expect thats the real trick.

Thanks for the input fellas!
 
I know a lot of the theories dealt with nutrient partitioning, and made claims that consuming too many fats with carbs...the insulin spike from the carbs causes the dietary fat to be stored as body fat.

On one hand, that seems perfectly logical, on the other hand it goes against the whole 'calories in vs calories spent'.

I can tell you that a carb-cycling diet I was on did follow this P+F or P+C meal types, and that I did drop fat pretty readily...
But that's anecdotal not scientific, and I was doing a fair amount of cardio too.

Well do they think that because they don't have carbs, the fat won't be stored? haha that's funny.

Yeah that does make sense, but like you said, only if you're eating more calories than burning. If the opposite is true, it's impossible.
 
I got an answer!!! i was talking to someone in the gym today about this and the sent me an email...
ready...

'Although a given ammount of carbohydrate and protein may have the same calorific value consider the fact that in terms of energy, protein is the most 'calorically expensive' nutrient. If you ate 100 calories of protein for instance, after the digestion process is complete, you are only really going to be 'netting' about 75 calories. With carbohydrates you net around 90 calories (per 100 consumed) and with fat, this is even higher at 97 calories.

Your trying to have less carbs to force the body to use fat as its energy source , once you have reached the ammount of protein that can be utilised if you still havent got enough calories in the diet and you have used my earlier recomendation of 1g of carbs per pound of body weight (cutting and on a training day ) then the balance i would make up with some extra fats these are not only calorie dense so you wont need a lot but also as your body is being deprived of carbs so its more likely get used as fuel.

An excess of protein isnt the best but is less likely to be stored as fat , i know your on a low carb diet so it wont be an excess but dont forget were trying to force the body to use fat as its energy source so adding in more carbs will stop that , this c and p below explains it a little in terms of excess protein .

Excess protein is more likely to be dispelled from the body than turned to fat. Protein is 58% likely to be converted to glucose, which can be stored as fat. Fats are 10% likely; on the other hand, carbs are 100% likely 100% of the time. This is (once maintenance calories are reached and glycogen stores are full for all of them). It is much better to err a bit on the high side of protein than not enough. Another thing about protein is its thermic quality that is it needs to be broken down into amino acids on digestion, thus creating the effect mentioned and actually using some calories. Many of your good vegetables also have this quality, and some fruits.

Carbs are energy. Carb calories are used to maintain your body weight/build muscle or can be burned off. If there is any extra left over at the end of the day, the excess will be stored as future energy, i.e. fat.'


Does this seem reasonable? I'm not quite sure what to make of it.
 
err.. fats are 10% likely to be converted to glucose, and thus just 10% likely to be stored as fat? Fat can be stored directly, don't need to convert it to glucose.

protein can also be converted to ketones, which can be stored as fat.. it can all be stored as fat easily by the body.

it's all about calories in vs. calories out. What we do with our diet during the day is (for some people) to try to maximize calories out (for example, eat a lot of protein, since it has a higher thermic value) and maximize the amount of weight gained as muscle and minimize weight gained as fat. Or if you're in a deficit, maximize losses from fat and minimize losses from muscle.

what these theories on when to eat and what to eat together tires to maximize is the amount of muscle buildt compared to the amount of fat built. Or as a way to make you able to eat more by having the diet composition make energy out go up.
