What should i eat to get more fat in my diet with out gaining weight? i was told always being cold and having thin nails is a sign of lack of fat in my diet but im afraid of gaining weight

A : A healthy diet and exercise is crucial for the development of lean muscle mass as opposed to just packing on fat. Junk food without exercise is not a good way to add fat to your diet. Eating high calorie, but protein and nutrient rich foods containing healthy fats such as nut butters, cheese, avocados and nuts is a good way to start. Using olive oil is also a great way to add healthy fats to your diet. That being said, you may want to speak with your doctor first before making any drastic dietary or exercise changes. Always feeling cold and having brittle nails can also be a sign of a thyroid disorder, so you may want to have that checked. Good luck!
