What you're saying is mostly correct, but poorly explained. What you're referring to is the thermic effect of food - the increase in metabolic rate due to processing food. Upwards of 30% of calories from proteins are used to process them, while <10% of carbs are used, and fats are some amount lower than that. This is partly why high-protein diets are recommended for fat loss. But this is all mostly irrelevant since TEF has nothing to do with targeting belly fat.

Hey BBSLM,

You're right, my explanation was poor. It was a 'rapid fire response' and I suppose I should have done a bit more refreshing/research before posting, but I felt it would be simple explanation and would get the point across.

Of course, bread has to be chewed and processed, but carbs are more easily broken down into glucose than proteins are into amino acids. I'll go out at a limb again, because it's years since I did biochemistry and I don't feel it necessary to research much further (will dig deeper if I have to), but if I remember correctly the chemical bonds that bind the simple sugars to form the complex sugars and ultimately the carb molecules are much easier to break down thereby requiring less energy.

The amino acid chains on the other had fold into complex structures which are difficult to break down and hence require significantly more energy.

Also, although not as significant, I do not believe that TEF has nothing to do with targeting belly fat. The more foods you eat with a higher TEF, the less chance of belly fat accumulation and the higher your chances of losing more belly fat.

Thanks for your feedback as I'm now more interested in the subject (didn't know up to 30% of protein and <10% of carbs were used to support basic metabolic processes). I will be looking into this further, but do you have a quick resource I could check out?

Hey Liquidus,

Proteins contain 4 calories per gram, carbohydrates 4 calories per gram and fats 9 calories per gram. So assuming a piece of bread with a grams worth of carbohydrate and a piece of meat with a grams worth of protein, they will both have the same amount of calories i.e 4 calories. However, going on BBSLM's update, 30% of the calories from the meat will be used up in metabolic processes compared to under 10% from the piece of bread.

coolarrow, a stone is about 6.34kg, so basically he weighs about 76kg or about 168 pounds.

For references, anything by Lyle McDonald. But for this topic specifically you can try the TEF section of this article:

Thanks for that. Have had a quick read through. Have left it open so I can go through it more thoroughly.

A piece of bread has, what, 100 calories? So accounting for TEF you're looking at about 90 calories. A 4oz top sirloin, for example, has about 240 calories, so accounting for TEF you're looking at 170ish.
But nobody eats just a single piece of bread, or just a 4oz steak, and protein is more satiating that carbs anyway, so the comparison is very realistic.

True, no one eats just a single piece of bread, but on average people are advised to have a 'balanced diet' which often has calories coming from the different macronutrients in a more or less equal ration i.e 40% protein, 30% carbs and 30% fats (this obviously depends on different individual metabolic types, but the ratio of proteins to carbs is not that high).

Another thing you can look at is typical meals in which you have way more rice in a plate than meat/sauce, or a pizza which has way more dough than topping, or a sandwich which has more bread than filling. With these quantity ratios, it is possible that the calories taken in from carbs and protein are not that far apart.

Dam metric system.

any thoughts on plant based proteins such as tofu/beancurds vs. animal based proteins?
