How the Adele Weight Loss Diet Compares to the Mediterranean Diet

Recently, Adele has been inspirational for those looking to lose weight. The Adele weight loss diet is much like the Mediterranean Diet but has some key differences. In this article, we explore the qualities of her diet and compare it to eating Mediterranean.

Adele and the Sirtfood Diet

In 2020, English singer-songwriter Adele lost over 30 pounds by adopting a new diet and regular exercise. The Adele weight loss diet is also known as the Sirtfood Diet, which was created by two British trainers in 2016. Like many other new diets, the Sirtfood Diet draws from more established diets like the Mediterranean Diet. Adele’s weight loss diet is plant-driven, anti-inflammatory and packed with antioxidants, which are all qualities of eating Mediterranean. However, a key difference between the Sirtfood Diet and the Mediterranean Diet is its rigidity.

The Sirtfood Diet has strict rules about acceptable foods, calorie intake and its overall progression. Although this type of diet worked for Adele, not all successful weight loss diets share these characteristics. Many of us will find more success with diets that are easy to follow and less restrictive like the Mediterranean Diet. Although it may take longer, if we are patient and loving towards ourselves throughout the process, adopting a healthy lifestyle, as opposed to following a diet, is the ideal way to go. This is where the Sirtfood and Mediterranean Diet really differ. 

What are Sirtfoods?

The Sirtfood Diet is composed of foods that are high in compounds called sirtuin activators. These sirtuin activators are thought to help people lose weight. Foods rich in these compounds include: kale, onions, red wine, strawberries, dark chocolate, walnuts, extra virgin olive oil and parsley. The main list of acceptable Sirtfoods totals around twenty different foods, which makes the diet narrow in its scope. On the plus side however, these foods are all nutrient-rich, minimally processed and can be anti-inflammatory.

Interestingly enough, sirtuin activators are found in mostly all fruits and vegetables but the Sirtfood Diet limits the acceptable foods to only those containing copious amounts of the compound. So, what does this mean? Well, it means that many healthy foods are left out of the mix on the Sirtfood Diet. Diets with more food variety tend to lead to more long term success.  

Calorie Restriction on the Sirtfood Diet

The Adele weight loss diet is quite restrictive in regards to calories. The Sirtfood Diet is composed of two periods of calorie restriction that last 7 days and then 14 days. During the 7 days, you are only allowed to eat 1000 calories and during the 14 days, you are allowed 1500. This strategy of calorie restriction is effective for short term weight loss. However, a big roadblock for people losing weight is that they don’t feel full while following the diet. Eventually, this catches up to most. It begs the question – even if you’re losing more weight in the short-term, is it worth it if it’s not sustainable? The reason the Mediterranean Diet is less of a diet and more of a lifestyle is because it is more oriented towards long term health improvement, which goes hand in hand with returning to and maintaining a healthy weight.

“This program is a way of life, one which I have adopted successfully, and more importantly one which I have sustained for over one year now. My weight remains steady at 160 pounds (down from 216). My energy levels rival that of someone 20 years younger than me (I’m now 57), enabling me to exercise in any way that I desire, from lifting weights to intense cardio sessions.”
— Michael Little

“After completing my 10-week program, I had a regularly-scheduled appointment with my doctor. Because my cholesterol has always been above the normal range (229 last year) I requested that she test it again this year. I’m happy to report that my total cholesterol dropped to 169, which is in the normal range, and all my other numbers improved as well.”
