Usually weight gain is slower than weight loss. For anyone who wants to gain weight, you need to improve your appetite and eat healthy. Weight gain should not happen only around the tummy area, but all over. Your face should glow. All this requires patience and consistency in following the diet. No appetite stimulants will be given. A slow and steady increase in your appetite along with improvement in energy levels and over all health should be induced through the diet plan. Each individual is different, so a customized diet plan for each person will be given.
