I was wondering if anyone could me some advice on how to gain weight in the most efficient way. I eat like a horse and most of it is carbs and proteins with fruit and veg also, yet I'm still thinner than id like to be. I have a feeling it might be because I'm eating foods that speed up metabolism or use up energy faster like coffee and beer etc. Could anyone tell me if they've had any miracle weight gain programs/diets, and also what foods to eat to slow down metabolic rates. Im no dietition, but I do know that if you eat a lot, you should put on wieght. With me though this is not happening. Any help? Thanks
