“Her whole focus during the weight loss journey has really been all about how she can be healthier and how can she treat her body better. It was never about losing weight.”

The Sirtfood Diet is the most widely credited method for Adele’s weight loss.

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.”
