Everyfood that you consume contains macro nutrients. Every macro nutrients contains calories.

You eat 3 pieces of fried chicken totalling 900 cals. Is still 900 cals. Where the calories coming from protein and fats.

You eat 900 calories worth of pasta, is still 900 cals where it comes combination of carbs, protein and fat.

Yes they are not exactly the same simply because each macro nutrients have different thermic effect in order for the body to digest them. FYI protein is the highest at about 20-25% with fat actually being the lowest. I've mentioned this already in my previous post and even shared a video by Layne Norton, which you immediately discarded calling those ppl idiots.

So from the above example after taking into account thermic effect of food, net calories for the chicken is indeed lower. But it is mainly thanks to protein's high thermic effect. Not fat.

If someone is anal enough to go into such crazy length to track their calories, all the power to them. But the basis is still CICO, no matter what diet you're on

the more popular system to determine thermic effects would be the GI index
