Singer-songwriter Adele stunned the whole world when she showed off her perfectly toned body on Instagram to mark her 32nd birthday.

The singer’s jaw-dropping weight loss has been nothing less than dramatic. Since showing off her new figure, social media has been abuzz with only one question: How did she manage to lose so much weight in just a few months? 

Now, it seems we finally have an answer to that question.

Apart from grueling workout sessions in the gym that Adele has previously talked about, the “Rolling In The Deep” hitmaker has enlisted the ­services of bespoke meal delivery plan Freshology, which drops off three gourmet low-calorie food right at her doorstep. 

The meal kit delivery service, which provides its customers balanced, freshly prepared, low-calorie real food, is endorsed by high profile celebrities like Sophia Vergara, Jennifer Lopez, Pink and Bono, to name a few. Talk show host Ricki Lake and actress Hilary Duff also avail of  Freshology's services.

The singer was keen to lose weight and decided to use the meal delivery service after it was recommended to her by Katy Perry.

“Adele made it clear she doesn’t want to feel deprived and loves wholesome, good food,” a source told the Sun.

The source added that since Adele is not too fond of cooking, the meal plan fit perfectly with her lifestyle and it was the best way to “maintain her hard work in the gym.”

The songstress took the 1,700 calories-a-day option from Freshology and followed it religiously. Her low-carb boxes included different food items for breakfast, lunch, and dinner.

The company allows customization of meal plans according to an individual’s taste. Clients can also go to their menu section and change their plan to what is suitable to their needs.

Meals include whole grain pancakes and egg quesadilla for breakfast, chicken burger and turkey salad for lunch and baked salmon and chicken stir-fry for dinner among other delicious foods.

The Grammy Award-winning artist reportedly lost about 44 kgs prior to her big reveal. 

Even her former personal trainer, Camila Goodis, confirmed that Adele reduced her calorie intake and she appreciated the star’s diet.

Adele's weight loss has been appreciated by her fans and they can't get enough of the picture she shared on Instagram on May 6. The picture, in which the musician donned a black mini dress, went viral on social media and netizens quickly applauded her determination to shed pounds.

As per the company’s LinkedIn profile, Freshology has a variety of programs and products that can help people in reducing weight and living a healthy lifestyle.

The company, founded in 2005 has its headquarters situated in Burbank, California.
