I'm thin mu tall is 181 my weight is 67 i a list of food to make better weight?

Units of measurement: Would you please list the units of your weight and height? In any case if you are otherwise healthy and just thin, do not be concerned. In a few years you will gain weight and look back fondly at this time when you could eat what you wanted and not gain weight.

Eat healthy: When you eat healthy foods, there will be less body fat and more muscle. Poor quality foods create a "wasting away" effect and no muscle tone. Muscle weighs more than fat, so you will gain weight. Very important to exercise also to build up proper body weight distribution.
