Sharing his before and after transformation pictures, the man, known as ‘miketyler77’, explained he is 40 years old and previously weighed 15 stone seven pounds.
However, after overhauling his diet, he managed to lose four stone.
His impressive transformation gained attention on Reddit, the platform he shard them on, with many commenters asking how he did it.
Responding to questions, he wrote: “I counted calories and was active at the gym, I also love outdoors so hiking biking etc.
“Diet is king no processed foods no pastas breads etc. I eat a lot of brown rice fruits vegetables and protein.”
Despite his strict diet, he did, however, have one treat day. He admitted: “I would give myself one day to eat a lot more calories.”
His efforts have worked, as he is now 11stone six pounds, and sporting an impressive set of abs.
Overhauling your diet and embarking on an exercise regime are both important elements of weight loss, but experts have advised another lifestyle element is also important.
Sleep has a major impact on waistlines, with new research showing those with regular sleep patterns found it easier to shed pounds from their waistline.
The study, which monitored 1,000 Brits, also found that the most effective dieters slept between seven and a half and eight hours a night.
Explaining how sleep impacts on weight, Pippa Campbell, Nutrition & Weight Loss Coach, said: “When we sleep we burn most of our fat, so if we don’t sleep this can significantly affect weight loss.
“Interrupted or impaired sleep can cause a pre-diabetic state, making you feel hungry even if you’ve already eaten, which can wreak havoc on your weight.
“Some of my clients do come to me complaining of poor sleep and I’ve found that people who work shifts often find it harder to lose weight.
“However, what you eat can contribute to a better night’s sleep which we look at in my weight loss programmes.
“For example, for some clients we need to address stress levels to help them sleep. This may be through breathing exercises and/or adrenal support supplements.”
There are things that can be done to ensure a great night’s sleep – and diet changes are key.
