Adele once famously said: “I'm not going to lose weight because someone tells me to. I make music to be a musician, not to be on the cover of Playboy,” but it’s easy to see that the angel-voiced blonde has been sporting a slimmer look since she first hit the global music scene in 2008.
While it’s safe to assume the 10-time Grammy award winner has naturally lost some weight from running around after her sweet three-year-old son Angelo, the Daily Mail has revealed the secret diet that has assisted in the stars incredible and healthy transformation.
The Sirtfood Diet and fitness plan, designed by trainer to the stars Pete Geracimo, encourages a full body slimdown by the consumption of plant foods such as kale and buckwheat.
Known as sirtuin activators, these foods not only suppress appetite, but also activate the body’s "skinny gene" or "housekeeping genes" which help control the way the body handles and stores fats and sugars, whilst regulating those pesky cravings.
“The Sirtfood Diet is all about losing weight and feeling fantastic through eating great-tasting food. It's based on extensive research into the power of key plant foods, which when added to our diet turn on fat burning and improve wellbeing,” said a source to Mail Online.
Along with a regular fitness regime, the diet allows Adele to munch away on a fairly regular diet (that includes red wine and cheese) making sure to incorporate green tea, cocao powder and turmeric – all of which are high in sirtuin activators.
Because we simply can’t have one without the other, the 28-year-old also combines the nutritional regime with a gruelling fitness plan, also set out for her by the former triathlete – who has previously sculpted the figured of Kim Cattrall and David Hasselhoff.
The trainer combines intense interval training with a circuit program known in the industry as the Modified Strongman Workout.
"Modified Strongman Workout is one of the fastest and most efficient ways of getting results," Pete says.
"It trains a wide cross-section of muscle groups and is very effective in boosting your metabolism and fat burning."
The workout program also includes repetitions of log presses, burpees and dumbbell squats, as well as hill sprints and underwater runs.

But don’t be fooled, your favourite singer, although incredibly driven to shape up with her latest health kick, is also refreshingly honest about her relatable hatred for the gym.
“I was trying to get some stamina, so I lost a bit of weight - not to be like a size zero or anything like that.”
“I mainly moan. I'm not skipping to the f---ing gym. I don't enjoy it. I do like doing weights. I don't like looking in the mirror,” she admitted to Rolling Stone magazine.
But perhaps the biggest change the yummy mummy has made in her efforts to slim down, was cutting out a habit that a lot of us are guilty of – tea.
“I used to drink 10 cups a day with two sugars in each so I was on 20 sugars a day,” she told The Sun before adding, “Now I don't drink it and I have more energy than ever.”
