How some of the foods like hummus/peanut butter/banana etc helps in both increasing & decreasing weight ?

Question

I often find this confusing, when I’ll search for weight gain foods they’ll show the same food for weight loss also. Why it is that?

Answer 1

Because eating healthy is more important than treating foods as a red pill that increases weight or a blue pill that decreases weight.
Purely from a physics point of view all food that you eat will add to you gaining mass (weight).
From a biology point of view is where the difference occurs.
If you maintain a calorie deficit you will see a decrease in weight *regardless* of how you get those calories.
