One of the worst things about being very overweight - other than the dangerous health conditions that it makes you more prone to - is that it ages you far beyond your years. Incredibly, in the 'before' picture, this man is only twenty years old. For the majority of those twenty years, he'd been spending too much of his time and money going to McDonald's and other junk food outlets, and washing all the food down with full-fat coke. By his own admission, he was destroying his body.
One day, he woke up and realized he didn't want to do it anymore. He took up yoga, and trained both his body and his mind to seek out healthier options. Without the constant diet of greasy food and empty calories, the weight simply melted away. Now he looks great, and he's given himself a second chance at life.
