A lot of people credit weight gain and obesity to lack of willpower. That’s just far too simplistic explanation. Some of the biggest weight loss transformations of all time will shed a proof on that.

That’s also not entirely true. Weight gain is largely a result of lifestyle and eating habits, but some people are at disadvantage when it comes to how they control what they eat.

Overeating can be driven by genetics and hormones and some people are simply predisposed to gaining weight.

Of course, this doesn’t mean that we can’t control ourselves. We can change our lifestyle and behavior with perseverance, dedication and willpower. If some people play on “easy” mode and lose weight easily, for some people it’s on level “intermediate” doing the same.

But claiming that weight gain is JUST a lack of willpower is far too simplistic and untrue.

We’ve made an incredible compilation of the biggest weight loss transformations of all time. Let this serve as a proof that it can be done!

David was on the brink of giving up his life. He was called the “650 pound virgin“.

His health and relationships went down spiral when his weight gain went out of control. But thanks to the amazing trainer Chris Powell, David was able to apply baby steps daily, by simply just walking around the house and focusing on one day without cheat meals. Day by day he succeeded at shedding over 100 kilograms!
