Hi every body I am bhaskar with 40kgs of weight and 5.2 height I want to become fat in 1 week as I am too weak for my age i.e:16 years please solve my problem

Good diet, exercise and sleep will make you stronger. Sports will help.
Being fat will make you heavier.
Too bad you didn't have 2 weeks.

Don't think you can do too much in a week, but I'm going to give you the same advice I gave zoro314.

You have to take in more calories to gain weight.

• Eat frequently! -- Make time for 3 large meals and 2-3 hefty snacks every day.

• Eat larger than normal portions at meals!

• Eat higher calorie foods! --Choose dried fruit,starchy vegetables, dense whole grain breads and cereals, hearty bean soups, nuts...

• Add lots of “extras” to food! -- Don’t eat anything plain.

• Add healthy unsaturated fats: olive and canola oil, nuts, seeds, peanut butter, avocados.

• Add healthy carbs and protein: honey, jam, dried fruit, wheat germ, nonfat dried milk powder, soy protein powder.

• Make beverages count! -- Drink shakes, milk, juice, etc. instead of water, coffee, tea, and diet sodas.

• Do resistance exercises! -- Weight training helps convert the extra calories into muscle rather than flab. Aim for 2-3 times per week.

I would try as Devorameira above your post mentions, or did that not work?
