then it is for the body to turn table sugar into usable energy?

Yes.

to convert amino acids into glucose, your body undergoes a process called gluconeogenesis, which results in the production of glucose from non-carbohydrate sources.

yes, it is easier for human bodies to convert table sugar into energy source.

All the amino acids have to go through more complex breaks and cuts from enzymes as well as deamination....much more costly thus the higher TEF of protein.

so a high protein diet will burn more caloires then a high carb of the same calorie diet?

Too many variables.

But I'll give out an example

P/C/F

Diet 1 250/200/50

Diet 2 150/300/50

Diet 1 will have a higher TEF and yes "burn more calories".

But what you have to consider as even more important is training intensity (burning more) and NEAT -- if you have low carbs and feel like crap then you're not going to be up and moving around as much doing random things.

Its not just about macros though
Steak vs whey
fruit loops vs bran
and what about broccoli vs whey

True, but It's pretty safe to say that in general and in reasonable diets, the diet with higher protein is going to have a higher TEF.

Plus he asked about Table Sugar as the carbohydrate example.
