As anyone who has failed to follow through on a New Year’s resolution knows, trying to lose weight can be a monumental struggle for those not gifted with a fast metabolism.

The path to weight loss can be a slippery slope where a little cheat snack can re-ignite old habits that will undo all your health gains.

People already know the dangers of obesity such as cardiovascular disease and diabetes. Still, people sometimes can’t help themselves and often can only look in despair and envy at the beach-ready bodies of movie stars and billboard models. But thanks to YouTube channel nollygrio, we learn of Amber Rachdi whose story gives hope to anyone who’s struggling to lose weight.

At her heaviest, Amber weighed in at over 650 pounds. That’s more than half a ton. So aside from the usual problems that obese people face, she also struggled with things that we normally take for granted. She couldn’t bathe herself, drive a car, or even walk. It got to the point where she had to move back to her parents’ house at the age of 23 just so they could take care of her.

But Amber decided that enough was enough. She didn’t stop with gastric bypass surgery. She took additional steps to change her lifestyle and that led her to lose more than 400 pounds.
