A formerly overweight man managed to lose five stone in just over a year by eating three boiled eggs for breakfast every day.

In a video shared to TikTok which has amassed more than 23million views, Ross Cotron claimed that the simple breakfast transformed his body in just 18 months.

Now a certified fitness trainer, he once weighed nearly 19 stone at his heaviest—but says the breakfast staple was key to his success.

Experts have long advised dieters to opt for breakfasts that are high in protein, as studies show these meals keep you fuller for longer, reducing the chances of snacking. 

Three eggs contain up to 20g of protein—roughly half of what the average woman needs per day, and over a third of a man’s requirements.

The unusual meal choice is also low in calories, totalling roughly 230, which can aid weight loss. 

Some studies have also found that a B vitamin in eggs called choline can help speed up the metabolism, accelerating fat burning.

In the comments of the viral video, others have raved about the effectiveness of the diet hack.

Ross Cotron managed to lose 72 pounds in a matter of months by eating three boiled eggs for breakfast every day

Now a certified fitness trainer, he once weighed 264lbs at his heaviest—but lost the weight by following a strict keto diet

One said: ‘I have done the egg diet it 100 per cent works. Rapid.’  Another added: ‘I did this for a month before and lost 1st 4lb. I can tell you this is true.’ 

And one said they lost nearly as much weight as Mr Cotron: ‘Did this for three months and lost 1st 5lb without working out and now I started working out and don’t have a bigger appetite I’ve lost 4st 7lb altogether.’

In other videos, Mr Cotron said he sometimes eats up to ten eggs a day, and that he even enjoys them fried and paired with cheese or with a steak.

A large quantity of eggs and meat is a common feature in the popular keto diet, which involves ditching carbohydrates and instead filling the diet with high-protein foods. 

Mr Cotron claimed that this way of eating has been crucial to his weight loss success. In another TikTok video he shared, the dieter claimed he’d ditched pizzas and beer, but still enjoyed burgers and steak—and champagne.

Champagne typically has fewer calories than beer and wine, and often comes in smaller serving sizes, contributing to a lower overall calorie intake.

A ketogenic diet consists of 75 per cent fat, 20 per cent protein and only five per cent carbohydrates. 

It aims, by almost eliminating energy dense carbohydrates, for people to achieve a state called ketosis—when the body starts to burn stored fat for energy instead, helping people lose weight.

The keto advocate shared his weight loss journey on his website, saying he made the change after he hit his late twenties and realised he had ‘let myself go’.

He said: ‘Before I knew it I was obese because years of overeating and drinking will catch up with you.

‘ I turned it all around though and have kept the weight off for a few years now.

‘I was looking for a solution to my ever expanding waistline, so I focused on forming new sustainable habits and behaviours by following a new diet, exercise and weight training around my busy lifestyle.

‘I still occasionally have enjoyable foods. I’m a pizza and Manhattans kind of guy. I still socialise and live a normal life around my family and career.’

England’s obesity crisis continues to deepen despite billions spent on treatment and prevention, new data shows.

Nearly two-thirds of adults were overweight, with an extra 260,000 people entering that category last year.

More than a quarter (26.5 per cent)—an estimated 14 million people—were obese.

Obesity can cause many health issues including heart disease and stroke, high blood pressure, high cholesterol and osteoarthritis.
