Why am I on the same diet and do exercise similar to friends but I gain weight more easily than others?
Are you sure that Input and Output between you and your friends are equa?
If we do not do yourself a favor, check before Input. Input is a very big matter. Eat dessert and drink flavored water containing high sugar ? Output is also a secondary matter if we do not Input > Output own body weight to increase it?
Try a strict control Input and Maximize Increase Output more.
Heredity also plays an important part in weight control. If someone in your family is overweight, has a big structure, big skeleton, it is likely that you are to be the same .
To view obesity in a broader view you must consider the height of the person too.
General guideline of weight in genders
Male Height (cm) – 100 = weight.
Female Height (cm) – 110 = weight.
