<u>Answer</u>:
A healthy way to gain weight would be to simply add more calories to your diet is a <u>TRUE</u> statement.
<u>Explanation</u>:
The number of "calories" that an individual consumes and burns daily plays an important role in determining his/her weight. A person who consumes more calories than he burns daily could become overweight whereas if a person is consuming fewer calories than what he burns could cause him to lose weight.
The best way to gain weight is to "add more calories" to one's diet while also keeping in mind the number of calories being burnt daily. The newly added calories should sum up greater than the total calories burnt regularly.
Hence, the statement about adding calories in the diet to gain weight is true.
