Adeleโs personal trainer has revealed the brutal diet that led to the hit singerโs incredible 45kg weight loss.
At the beginning of January, photos emerged of the Hello hitmaker sporting a considerably smaller frame while enjoying a vacation with celebrity pals Harry Styles and talk show host James Corden in Anguilla, an island in the Caribbean.
She was spotted by fans enjoying herself on the beach, and revealed she has lost around 45kg.
โAt first we barely even recognised her because she lost so much weight,โ 19-year-old fan Lexi Larson told PEOPLE magazine, after meeting Adele at a restaurant in Anguilla.
โShe told us she lost something like 100 lbs [45kg], and that itโs such a crazy positive experience.โ
While Adele hasnโt publicly commented on her weight loss, she did allude to her new, healthier lifestyle on Instagram back in October.
She captioned a photo of herself: โI used to cry but now I sweat.โ

โShe looks amazing, she changed her lifestyle, she changed her diet,โ Camila said on UK breakfast show Lorraine.
โI believe now sheโs into working out, sheโs working out more and more but, itโs 90 per cent what she did was diet. Thereโs no secret, I didnโt help with any diet. She started doing this certain diet and now sheโs maintaining just eating healthy. Itโs a good diet to shed the weight,โ Camila said.
And she revealed exactly how many calories Adele was eating in a day at the start of her weight loss journey โ and the number might shock you.
โThe first week is pretty intense โฆ itโs a lot of green juice and 1,000 calories a day,โ she revealed.
โGiving up processed food, sugar, soda and get into an exercise routine, like cardio and strength training, will change peopleโs bodies.โ
1000 calories is the equivalent of 4184 kilojoules. According to established health guidelines, the average Australian should eat around 8700 kilojoules in a day, but considerably less if they are looking to lose weight.

Adele showed off her weight loss in these Instagram snaps over Christmas.
(Instagram)But some of Adeleโs fans are worried that her diet is too restrictive โ and even dangerous.
โ1000 cal per day is not sustainable and you donโt need a personal trainer for this,โ one fan wrote on Instagram.
Another said: โI would be more wowed if these results would have been reached through clean eating with normal calorie intake and trainingโฆ I am not a professional trainer, but I am qualified enough to know that this is not a very healthy way of losing weightโฆ this is just my opinion for this you donโt have to be a guruโฆ Love Adele either way, but in her new pics she looks tired ๐คโ
A third person wrote: โAdele is gorgeous as always regardless of her weight โค๏ธโ

โI used to cry, but now I sweat.โ
(Credit: Instagram)But sources close to Adele say her new transformation isnโt just about losing weight and looking skinny.
โYou see, her new look is as much, if not more, a mental thing as it is physical,โ a source told PEOPLE magazine
โItโs easy to just focus on her physical transformation, but this is really about something bigger. She got to the point where she didnโt feel great. โShe knew she had to change something because she wants to be the healthiest mum possible.โ
Adele has a seven-year-old son, Angelo, with her ex-husband Simon Konecki.
