I am 5 foot 7 and 42kg. i want to put on 10kg in one month. how can i do this? i want to do the gomad diet but at a quarter gallon of milk a week.

GOMAD diet: eh gads!! - GOMAD (gallon of milk a day) diet. Potential side effects are bloating, possible acne, increased blood lipids and digestion issues - There are better more reasonable ways to gain weight. I think your plan of using only 1/4of a gallon is ok - just combine it with a balanced high calorie diet - low fat cheese, meats, pasta potatoes. Good luck
