How can one increase weight?

Take to a diet for three to four days.

Take 100 to 150 grams of bran with the fruits. The best way will be to mix bran with a fruit like papaya. It will increase appetite, improve the digestion and remove costiveness, if any. One will tend to eat more and the capacity to assimilate food will be increased.

Foods like flour, rice honey, raisins, figs, dates, butter, and etc. can help increase weight. Sweet substances can increase weight than fatty foods.

Those wishing to increase their weight should become pure vegetarians and eat fruits,
rice, flour, fresh vegetables, bananas, dry fruits, butter, and milk. Germinated wheat is also extremely beneficial if taken in the form of gruel mixed with hot
milk.

Take plenty of water, exercise and fast once a week.
