How do you put weight on quick?

Answer 1

Eating too much saturated fat. Anything that's full of lipids (fats and oils), red meat, or an avocado, are all bound to have saturated fats. Sugar and carbohydrates usually turn into fat, too.

Answer 2

if you want to put on fat, you could eat lots of carbohydrates (like pasta). you can also eat nuts - those have (good) fats and protein and fruits with a high sugar content, like bananas, grapes, tangerines, mangos or any dried fruit. eating a lot of refined sugar in a short time is not advisable, since it increases the risk of becoming diabetic. fried food is also not a good idea because it increases bad cholesterol. so does pasta, but a little less. any way you go, make sure you still have a balanced diet, maybe even take some vitamins. anyway, if you body fat is dangerously low, you should be asking a doctor, not just online.

if you want muscle, you could try eating a big stake or a protein shake after working out and taking supplements made especially to help with muscle mass. do not eat fatty foods after a workout, unless you want to gain fat.
