Burning more calories than you take in is the formula to weight loss.

Eating lean meat and green vegetables can help with slimming down.

Another notable figure who has lost weight is Michelle Mone.

The lingerie mogul shrank from size 22 to 10 and lost 8 stone.

Adele’s weight loss has also inspired fans after she lost around seven stone. 

It’s reported that she followed the Sirtfood diet.

Nutritionist Aidan Goggins, co-author of The Sirtfood Diet explains: “For the first three days, you restrict calorie intake to 1,000 calories a day, which includes drinking three sirtfood green juices plus eating a sirtfood-rich meal and snacking on antioxidant sirtfood bites.

“For the last four days, you up the calorie intake to 1,500 calories a day by consuming two sirtfood-rich meals and two green juices, cutting out the bites.”
