A 43-year-old man has shared his incredible weight loss success on the keto diet plan.
Sharing his before and after pictures on Reddit, he wrote a detailed account of how he did it.
The man slimmed down from 24.2 stone to 14 stone at his lowest weight.
Another man recently lost 13 stone on a similar weight loss plan, so what is it?

The Reddit user turned to the keto diet, or the ketogenic plan, to lose the weight.
The keto diet is a low-carb plan that advocates eating high amounts of fat.
It is devised to trigger ketosis, which is when the body uses fat as its primary fuel instead of carbohydrates.
Carbohydrates are foods that are broken down into sugar glucose in the body. Examples include refined sugar, but also bread, pasta, potatoes and carrots.
So, how did this man begin his impressive weight loss diet?
He told interested internet users: “So sugar was cut first, Fall of 2017, and I lost about 30lbs., just cutting sugar.”
