Hello Mahender..
I have gone through your post in which you are concerned about not gaining weight in spite of trying powders for weight gain.
Firstly, the built and personality of a person is genetically determined and can be influenced by factors like diet, exercise,
hormonal balance in the body, etc.
Secondly, these weight gain products are only dietary supplements & should not compromise on routine healthy food such as:
1. Consume more of natural diet like fresh fruits, green vegetables, milk, eggs, wheat, etc.
2. Avoid oily and junk food.
3. Stay away from
smoking & alcohol.
One more thing...do not try to gain weight all of a sudden under the influence of medications. It is a gradual process & may take time.
Under such conditions, intake of medications or weight gain supplements without proper guidance may have harmful effects on the body.
Best is to stay active, exercise regularly, avoid
stress, get good sleep, think positive and stay happy.
Wish you a healthy life.
Take care.
