Gaining weight is in no way easier than losing weight. While most are worried about how to lose weight, those having a thin body and having stuck on the lighter side of the weighing scale are frustrated when they see no sign of weight gain in spite of increased food intake. 'Eating more' does not help in gaining weight unless you are following a controlled and balanced weight gain diet chart. Healthy diet and regular exercise help improve your looks and stamina. Being underweight can stem from an improper diet, eating disorders, chronic diseases or lack of proper physical activity. Sometimes, there are hereditary reasons too. Underweight and frail persons may have to face chronic diseases because of weak metabolism and weak immune system. 'Eating more' is not sufficient as the goal is not 'gaining fat' but 'gaining lean mass'. You are expected to consume more calories than you burn, if you want to gain weight fast. You need to consume healthy food. High consumption of fat or fast food may result in weight gain but then, you may eventually have to face serious health problems. To determine whether you are underweight or not, your age, weight, height, waist size, and any ailment you might be suffering from, are to be taken into consideration. Body mass index (BMI) shows the body weight status. BMI = weight in kilograms/(height in meters squared) OR BMI = (weight in pounds/(height in square inches)) x 703 This formula would help find out the correct weight for your height. The average BMI table informs us that people with BMI less than 18.5 are underweight. So, check how many kilos you need to gain to have BMI greater than 18.5.

BODY	BMI
Underweight	Less than 18.5
Normal	Between 18.5 - 25
Overweight	Between 25 - 30
Obese	Between 30 - 40
Very obese	Over 40
