So what does he eat in a day? The man revealed that keeping his carbohydrate intake down was the key.

What is the keto diet?
The keto diet is a plan that limits carbs and encourages eating more fat. This puts the body into a state of ketosis, meaning that it burns fat as its primary fuel, not carbs.
The plan has proved very effective in aiding rapid weight loss.
But this wasn’t the only diet plan he followed. He also claimed to use intermitted fasting, so what is this?
Nutritionist Hebe Mills, founder of Hebe Mills Nutrition, is an associate nutritionist.
She told Express.co.uk: “Intermittent fasting is a concept where participants alternate between eating and fasting and eating in specific time periods.
“It doesn’t restrict what you’re eating, it just dictates a time period when you are able to eat.”
Gordon Ramsey’s weight loss has been impressive over the past few years.
Surprisingly, the chef – who is dad to Megan, 21, Jack, 19, Holly, 19, Matilda, 17,and four-month-old Oscar – revealed he’d managed to slim down by eating more meals.
Speaking to the Today Show, he said: “I’m very good now at eating five times a day, but small amounts as opposed to big breakfast, big lunch and big dinner.”
“There’s nothing worse than eating dinner at 5.30 and then having to get up and cook for three hours.”
