What is the Fastest Way to Gain Weight?

There isn’t really a fastest way to gain weight. Just like there isn’t any real way to lose weight fast. Your body takes time to gain and lose weight. It isn’t healthy to gain or lose any weight fast at all. In order to gain weight though, you’ll need to consume more calories than you are burning. Start by consuming a few hundred more calories a day, while cutting back on the calories you already burn.
