What food should I have to become fatter and more muscular?

I'm 16 and I have extremely skinny even anorexic forearms. My biceps, abs and legs are pretty muscular and I've tried eating a lot of food but I don't gain weight because of my metabolism and because I play a lot of basketball. I only weigh 53kg at my age which is abnormal and far too low. Any diet tips to gain weight especially on my forearms and exercises? BTW wrist curls don't help. They seem to make my forearms smaller.

Ok, in order to bulk up you need to lift weights that are roughly 70 - 75% of your 1 rep max (the max weight you can perform one correct rep of on any given exercise). Basically you need to lift a weight that you can lift 8 - 10 reps of (with correct form) and hit failure on the last rep (you cannot complete 1 more rep). You need to build up to to about 4 - 5 sets of this for each exercise. This form of lifting is called hypertrophy, i.e. bodybuilding. In conjunction with this you also need to increase your daily calorie intake by about 500 calories per day, ensuring that you consume protein within the 10 minutes after you train, and also every 2 - 3 hours throughout the day (egg whites, chicken, tuna, lean red meat). A protein supplement is the best way of taking in these extra calories and protein. You will also need to ensure that you are consuming enough complex carbs (fruit, veg, etc) to provide you with the fulw for your workouts.

If the wrist curls are making your forearms smaller then I am guessing that you are over training. You need to give your body at least 48 hours rest after lifting weights. This is the minimum. Anything less than that and you are over-training which will only cause the muscle to break down and wear away. I would suggest that you pick different muscle groups and work them on alternative days, chest and triceps one day, biceps, forearms and back another day, legs and shoulders another day. This will allow you to lift weights everyday if you wish, whilts giving the various muscle groups time to recover.

Another fun way to build your forearms is the NSD Powerball (check it out on the net). I play basketbal too. I got one a couple of weeks ago and i'm noticing an increase in strength in my forearms.

Hope this helps you

I don't siggest that you become "fatter" because that is unhealthy for you... but being more muscular is good... you can do so by a combination of well balanced exercise and diet, there are a few good weight loss programs I suggest:
