Your specific body metabolism (the rate at which your body burns calories ) and lifestyle (sedentary or active) and other factors determine your net weight gain or loss. For details on other factors see the below URL :-

What affects metabolism?
What do you think has the biggest impact on your metabolism? Activity levels, thyroid function, and age do affect metabolism but not nearly as much as muscle tissue. The more muscle you have the more calories you burn regardless of how active you are, how old you are, etc. Muscle is metabolic reactive which means muscle burns calories even when you are doing nothing - 24 hours a day.
Here's a list of some of the factors affecting metabolism in order of greatest impact to least:
# 1. Muscle tissue.
# 2. Meal frequency. The longer you go between meals the more your metabolism slows down to conserve energy.
# 3. Activity level. activity is important but doesn't make any difference if you don't match your eating to your expenditure.
# 4. Food choices. Except low-fat diets which tend to result in poor hormone production which leads to a slower metabolism.
# 5. Hdyration. Over 70% of bodily functions take place in water - not enough water causes all your systems to slow down and causes unnecessary stress.
# 6. Genetics. Some people have higher metabolisms than others.
# 7. Hormone production and function.
# 8. Stress. Stress also can slow metabolism by placing extra strain on numerous systems. Many people tend to over eat when "stressed out"

I lost quite some weight (65 pounds and counting) by going on a low carbohydrate diet. For that reason I would hate to advise anyone on how to GAIN weight!. But if you really have to (i.e for medical reasons, etc), perhaps you can try doing the opposite ;-
1. eat a lot of carbohydrates (garri, bread, pounded yam, etc)
2. eat high calorie foods.
3. eat very late at night
4. live a sedentary lifestyle
5. etc.
Good luck,
