how can i gain weight

Hi lazoof, some people have really high metabolism and as such have problems gaining weight, especially on healthy way. Best tips are reduced physical activities and more fat, sugar intake, but sometimes this just doesn't work. My advice is to try some appetite helpers and heavy calories meal, rich in proteins and fats, eat a lot of avocado, physical activities recommend some which reduce stress and are not so intensive, like some kind of yoga and or walking. Hope this helped and good luck.
