Why is it so hard to gain weight?

Every body is different, either it's very easy অথবা not really. It could be your metabolism, but the best person আপনি could probably ask is your doctor. I, myself, find it very difficult to actually lose weight. It was easy to put the weight on but that's just my body. As I said, every body is different.

I know this might sound pain in the ass, but আপনি need to start weighing your খাবার depending on your weight. আপনি do want the healthiest way possible right? not just gain fat..

I'd advise আপনি to add আরো protein shakes and I'm not talking about the powder, fuck that^^ just make it yourself at home.

There can be some factors that might make আপনি underweight e.g. smoking, having too little sleep, work out routine that targets wrong areas, eating unhealthy অথবা any other thing that messes up metabolism. But it also might be simply genetics and then there's little আপনি can do about it. Hopefully আপনি find a solution that works for you!

There’s a massive tapeworm inside your digestive track that steals all the calories and nutrients from all the খাবার আপনি eat দ্বারা consuming the remaining খাবার particles that travel throughout

It's called McDonald's. They'll fatten আপনি up in no time
