I'm 18 years old. I'm 5 ft 7 in. and 100 lbs (45 kgs), BMI says I'm severely underweight, my friends say I look like a skeleton. that's why I don't go out much. I tried Optimum Nutrition Whey 100% Gold Protein a few months back for 1 month and it did nothing,
Someone told me that Mega Mass could do the trick, I went to the store, got Weider Mega Mass 4000, the box says 1 Scoop in 2% Milk. Now I don't know what is 2% milk (I don't think we get it in India). So I took it in the normal milk we get here and after a few days observation I found that after taking a Shake of Mega Mass in normal milk (cow milk) I get Lose Motions
that's why I stopped taking it for a while but then I thought I'd take it in Water so for the last few days I'm taking it in water without any problem.
I don't go to gym. I need some help I Seriously want to gain weight. What should I do
Any help would be appreciated
Thanks
