| What kind of weight are we talking about? Muscle most or do you not really care?
If you don't really care, go high carb food like a thick cut of fatty read meat; ice cream, peanut butter and jelley sandwich, and lots and lots of junk food.
If you want to try and gain muscle, try to consume about 150g of protein per day via Chicken, protein shake, milk, diary product (cottage cheese), etc.
In the morning, eat your carbs like pancake, waffle, cereal and milk, bagels and same in the afternoon. Tapper off in the evening but eat some cottage cheese before bed or some slow digesting protein so that the body has building blocks to use with while you rest.
Nobody's advice is also solid. |
