7 bizarre pop star diets: from Beyoncé’s Master Cleanse juice fast and Madonna’s macrobiotic lifestyle to Katy Perry’s mushroom-based M Plan – but did Adele even do the sirtfood diet?
- Christina Aguilera has done the 7-Day Colour Diet, which involves eating foods from one colour group a day; Mariah Carey just eats Norwegian salmon and capers
- David Beckham revealed on TikTok that his Spice Girl wife Victoria only eats grilled fish and steamed veggies – but she later claimed she drank alcohol regularly, too
Diet trends come and go, and in showbiz, celebrities are usually pretty quick to jump in on the hype of the season. While some A-listers swear by a simple, balanced diet of fresh, unprocessed foods to stay healthy, others may pick up on strange diets which might not always be backed by scientific research.
Here are some female celebrities who’ve kept to some truly bizarre celebrity diets.
1. Adele’s popular sirtfood diet – which she never actually tried
However, she said in a recent Vogue interview that she hasn’t followed any particular diet, and “inside sources” claiming to have spoken to her were unreliable. “All these other people have come out saying that they trained me,” Adele told Vogue. She called them “weirdos”, adding, “I’ve never met them in my life!”
The sirtfoods diet was initially launched by a 2016 book claiming that the specific foods could activate a protein called sirtuin, which may support healthy metabolism and longevity.
But more research is needed to back up the benefits of sirtfoods. As of now, while the foods on the diet are healthy, they’re not likely to have any particular weight loss benefits, experts previously told Insider.
The diet also involves a strict calorie-cutting phase of 1,000 to 1,500 calories daily, which experts have previously said is dangerously low for adults.
