Not entirely true. High protein diets allow you to eat more calories because the thermal effect of digesting protein results in a loss of 25% calories (of protein).
Yep. But even though almonds are ~20% protein, they are also ~50% fat. It's not the best protein source by a long shot.
While the TEF of protein does reduce it's net caloric contribution by about 25%, that doesn't matter if you eat in excess of TDEE, which will result in weight gain regardless of the kind of foods eaten. Upping protein to reduce hunger works really well, but there are better foods than almonds to do this (cottage cheese, meat, fish, whey protein, etc).
