I am skinny, I want to gain weight

What you need to know:

Eating a lot of fat to gain weight, whether one succeeds or not, is likely to lead to complications such as heart disease and stroke resulting from bad fat depositing in the blood vessels

Dear Doctor: I am a skinny man and I have been advised to eat fatty foods to gain weight. However, this is not happening. What can I do?

Dear Amos: Generally weight is determined by genetics with factors such as diet, sedentary life, exercise, age, sex, and drugs playing a key role.
Whereas some people are genetically prone to gain weight when they want to, those not prone may not gain weight even when they eat fatty foods.
Eating a lot of fat to gain weight, whether one succeeds or not, is likely to lead to complications such as heart disease and stroke resulting from bad fat depositing in the blood vessels.
It is more important to be healthy even when you are skinny instead of trying to put on weight at your health’s expense.
