Adele recently shared an incredible photo to her Instagram as part of her 32nd birthday celebration revealing that she has lost over 100 lbs.
This photo has sparked congratulations and controversy from the public in equal measure.
For years, it’s been rumored that the star follows a meal plan based on the book “The Sirtfood Diet.”
The regimen includes multiple phases and focuses on “cellular wellness at a genetic level,” according to Aidan Goggins, one of the creators of the diet.
The Duchess of Cambridge’s sister Pippa Middleton and boxer Connor McGregor have also been said to use the diet.
According to Goggins, the Sirtfood diet was created as “the antidote to conventional dieting.” He and his partner, Glen Matten, were both “diet skeptics” because of their history as nutritional medical scientists. Instead of focusing on weight loss, the Sirtfood diet is based on activating sirtuin genes.
Sirtuins are proteins that are members of a family of enzymes. They activate and are typically utilized in response to stress and metabolism, explained Kristin Kirkpatrick, a registered dietitian.
“The weight loss is not the primary goal, but as a consequence of rejuvenating our cellular wellness at a genetic level, which essentially resets our metabolism,” said Goggins.
“Secondly, in contrast to other popularized diets where the focus is on cutting out foods, with Sirtfoods we can only reap the benefits through eating, and this means indulging in your favorite foods, not restriction.”
Kirkpatrick, who works with the Cleveland Clinic in Ohio, said that she’s had patients come to her asking about the Sirtfood diet multiple times, and while there is some science to support the effects of the diet, she said many of the studies and research are very new.
“I think the diet is harmless, but we don’t have data showing that it’s got long-term sustainability,” she said.
“The whole theory behind the diet is that certain foods are going to activate these sirtuins, which are related to proteins in the body.”
Kirkpatrick noted that the Sirtfood diet operates similarly to intermittent fasting diets, which have also been shown to help with weight loss.
Goggins said that when he and Matten worked in a high-end private health club in London, they became “increasingly concerned” about “increasingly extreme diet trends” and the foods that people “villainized.”
“You’d be afraid to eat,” he said. “And it all became about reducing calorie intake.”
When creating the diet, they wanted to make sure that people felt free to eat some of their favorite foods while still getting important nutrients.
“It is important that we not only get plenty of these foods in our diet but also ensure our meals contain a diverse array of them as it is the synergy of their combination in meals and juices where the real benefits come from,” Googins said.
“Whenever I’m about to eat meat I always see my little dog’s eyes.”
Adele has not publicly commented on her weight loss, apart from in the caption of an Instagram post from October last year, where she suggested she had ramped up her exercise regime, writing: “I used to cry but now I sweat.”
