A man who lost six stone two pounds has shared his before and after transformation pictures and revealed how he did it.

Taking to Reddit, the man, known only as his username ‘bluestic’, said he was 19, 6 foot, and lost a total of 88lbs (six stone two pounds).

He titled the post: “A moderate gym routine and a keto diet goes a long way!

His post garnered lots of comments from people wondering how he achieved his goals.

One asked: “Would you please share what a day of eating looks like?”

He responded: “I eat my first meal around 12 and I tend to make eggs and bacon with cheese as my go to.

“For snacks I eat cheese sticks, pepperoni discs, or sardines mostly, when dinner comes around I like to look up low carb keto recipes.”

He did not share further details of his gym routine.

The keto diet is a low carb and high fat diet that is smilier to the Atkins diet - except there are no complicated phases to work through, making it a little easier to follow, especially for diet beginners.

The plan is said to cause fast weight loss while allowing dieters to remain satisfied, thanks to the large amount of fat included.

The diet sends the body into a state of ketosis, when the body burns fat for energy, instead of carbohydrates.

Over 20 scientific studies have shown this diet results in high levels of weight loss.

Others who have followed the plan have shared their weight loss transformations online.

One poster ‘LeftyKreh’ explained he was 19 stone before starting his weight loss journey. But just 11 months later, he was down to just over 13 stone.

Explaining he had “dieted before” but nothing worked, LeftyKreh went on to detail what spurred him to finally lose the weight.

As well as keto, he tried intermittent fasting as part of his push to lose weight.
