Sport a diet of pure protein and fats?

Then what is the ' benefit ' of opting to fuel exercise with protein when your body is designed to preferentially use carbs ( glucose/ glycogen ) to fuel exercise and your body is also designed to spare protein for it's intended purpose - primarily tissue growth and repair.

Since carbs aren't fattening, and carb based energy is the preferentially fuel for hard exercise - what's the rationale to cut carbs to almost " 0 " in favor of protein ( and to a lesser extent ) fat ?
 
not necessary phate? then your body will be in ketosis which if high enough can be very dangerous, harder to break down fat, excess protein -> huge load on the kidneys, water loss, increase risk for cancer maybe (?), bad breather etc. stick to the glucose...
 
If he said thats what he did then who are we to say he didnt. I bet he stuck to his plan and completed all his scheduled workouts. Although it doesnt say he did any weight training, I am wondering how he managed to keep ALL his lean mass.
 
Possible? Yes, minus the keep all the lean mass part. Prob not the best way if you're not 5 days out from a BB comp or looking to lose quick water weight.

IMO, carb cycling is a better option; or a 'low'er carb diet.

And a Q to nicolasd, ketone = R1-C=0-R2? Is that the ketone you're speaking of?
 
Well, he said he was getting 300 grams of protein and 150 grams of fat. He said he had toast in the morning and 60 grams of carbs post workout. Other than that he didn't have carbs for the rest of the day.

On cheat meals he would just go crazy with carbs, he said he would eat all kinds of carbs including things like bagels.

He definitely did weight training too along with his cardio.

I hear what your saying wrangell, I think I will stick to using carbs to fuel my workouts.. still though I think I may need to reduce my carbs.

This is a great article I found today about carb cycling:

TESTOSTERONE NATION - The Carb Cycling Codex


Today my protein was 151 grams and 37%
carbs 258 at 46%
and 33 grams of fat at 18%

total calories 1746

I weigh 150..

What do you think I should adjust?

no way hose, the brain doesnt work on ketos because ketos dont support neuron firing. Where did you read that.

Just about any source on keto diets. Just looked it up on wikipedia
Ketone bodies - Wikipedia, the free encyclopedia
and apparently the brain can get a lot of its energy from ketones but not all, if wiki is right here.

So you're right that it still needs some carbs, I didn't know that. Anyway, most diets have you getting at least 30g of carbs a day, and even though I have no idea of the amounts needed, I'm guessing that is enough.

After having about 40-50g of carbs a day for 1 week, I honestly think that I worked with perhaps more focus than normally.

You're not using proteins for fuel, you're using fats. The rationale is you go into ketosis where your body actively breaks down your body fat to ketones to have it readily available as a source of energy. If you get too many carbs (over what can be stored as muscle glucogen), you're knocked out of ketosis, as I understand it.

I went into ketosis in 3 days, then lost almost 2lb of presumably fat in the next 4 days, it's much faster than regular cuts.

Not true, it can be edited by anyone in the entire world. So if they put in something that the editors of wikipedia don't know about it just slips by, meaning that a whole lot of information on wikipedia can be false.

Exactly. Anyone can change wiki. How about you go try to change something on wiki and tell me if it actually gets changed?

They have things that alert them to when ever someone changes information on an article, and for the article to actually be changed for real it has to be verified by the wiki community and then goes into effect

Its not as easy as just changing it and clicking save.
I have seen nothing inaccurate in all my life from wikipedia. Most reliable source I use for homework and personal reasons.

Or about finding me something false on the information on wiki?
 
No I would agree, especially for high school work. I always used that on history homeworks, and even though every teacher would say don't use it you can't trust it, I would do it anyway, but you have to know that everything on there isn't necessarily true. This is especially important when you are looking at either very mundane topics, or highly specific topics where the editors may not be knowledgeable enough to know whether or not something is true.
 
Grams for grams, 1 gram of protein provides 4 calories, and 1 gram of carbs provides 4 calories. Fat provides double at 9 calories per gram.

Strictly speaking, eating purely protien will be the same as eating purely carbs.

As for cutting it out of your diet? A big no no. First off, carbs are the body's primary energy source. By fueling your body with protein, you're asking to feeling tired and down most of the time. Also, tissue and other vital organs in your body require carbs to rebuild itself.

Ask Dr. Atkins who died of a massive heart attack (I didn't know until CCR said something one day). Why? Some say it's because he's genetically predeposed to have one... other people, which I believe, is because his diet lacked carbs.

1. Wiki is a credible source ( to me anyway )
2. I said protein can still be converted into energy for your HIIT session, but also stated that carbs would be more efficient ( if you didn't take my quote out of context )

How old are you, 16? You've been using wiki for what, a year? Even so if you have no prior knowledge of a topic and are going to wikipedia for information, how would you know it was false or true if you dont know about the topic?

Wikipedia wasnt allowed as a source in my classes because it is not credible.

Protein the same as carbs? :confused: Not when we start talking about insulin responses.

I recently read an excerpt from a study that followed dieters for 10 years who were low carb. They were actually healthier then the carb eating counterparts...(note:this is a short excerpt from the excerpt)
 
dont get to excited about that
