Thread: carbs, protein, fat

I just skimmed through the article, it references Protein Toxicity when there is a lack of Carbs and fats.

What about the scope of the subjects we are dealing with here. Bodybuilders are looking to preserve muscle while in a caloric deficit. Muscles require Protein (amino acids) would it not make sense to have a higher protein intake when catabolic. Compared to when bulking, the muscle tissues wouldn't need to be used as an energy source?

Where did Jodi go?

When you said that you would have a higher protein intake when cutting in comparison to a bulk, I felt that it would result in a considerably higher percentage of total cals from protein when cutting in comparison to bulking.

If carb & fat intakes suit activity levels (see Fig. 2. in Determinants of the variability in respiratory exchange ratio at rest and during exercise in trained athletes -- Goedecke et al. 279 (6): E1325 -- AJP - Endocrinology and Metabolism ), then the body should not use muscle protein as an energy source.

Oh, and hi Sara!

lol. im sorry I did not understand any of that. so for a bulk I want 1.5 g of protein per LB?

Yup. 1.5g of protein per lb is fine for bulking. If you eat 20kcals per lb bodyweight, that works out as 30% of total calories from protein.

how much of the res should be carbs and what should be fat?

Percentages don't really work because they are totally calorie dependant.

For example, if I need 250g of protein per day and I am eating 2500 calories, that is 40% of my caloric intake. If I need 250g, but I am eating 3000 calories, that is 33% of my caloric intake. Either way I have the proper amount of protien. What percentage I have it set at doesn't matter worth a darn. Does that make sense?

Set your protein and then worry about the rest. Don't worry about the calories.

That depends on what you're doing. Pre-workout, you need slowly-absorbed carbs e.g. basmati rice, sweet potatoes etc. Post-workout, you may want to use dextrose/maltodextrin to replenish muscles. At times like these, keep fats low to minimise bodyfat storage.

The rest of the time, when you're sitting watching TV or surfing the internet and not burning carbs, keep sugary & starchy carb intake low and eat more fats of all types, keeping a balance between omega-6 & omega-3 by eating oily fish (tinned tuna and fish in sunflower oil don't count) or flaxseeds/flaxseed oil. You can eat veggies anytime. You can eat low-sugar fruits like berries, stone fruits, citrus, apples & pears anytime. High-sugar/starch fruits like bananas & grapes are best eaten when you're active and burning carbs.

I'm a proponent of John Berardi's principle of proteins+carbs when active and proteins+fats when sedentary.

ok. I understand P funk that I need to figure that out. But how do I figure it out? anf thanks nigeepoo

I say anywhere between 1-1.5g per lb of lean tissue is okay for protein requirements.

alright thanks. now that I found that how should I find my carbs.

How much protein would you need on a cut? Right now I'm sitting at around 180g of protein at 155lbs, but 1.5g/lb would put me a pretty good amount over 200g.

On a cut, I'd say no more than 1g/lb.
