Hello there....., Only calories won’t add to your body weight,include the right amount of proteins to your diet..... Have six meals in a day – three big meals and three small. Breakfast, lunch, and dinner should be heavy and calorie-rich. A heavy dinner adds weight to your body as your metabolism is not as active when you sleep as compared to when you are awake.... Eat more of fresh fruit, dry fruits, sprouts, green leafy vegetables, healthy fats....
