But it also depends on how much you are eating at the moment. ... but I would suggest that when you are 3-4kg from your goal weight you should be eating around 2800-3500 (+/-) each day. Following the MM diet is to be recommended if you are trying recovery on your own. Because your body does need alot of energy. ... just eating 1500kcal isn't enough even if you are gaining weight. It's also about your body have energy to repair your organs and the damage done on the inside as well as your body having enough energy just to function. And also think, if your gaining weight eating so little what will happen when you reach your goal weight? Instead you want to increase your intake as much as possible during recovery so you can eat alot just for maintenance. ... and your body should adapt with the calorie increases. I would suggest 200-500kcal increase every 2-4 weeks.
