Earlier this year, British pop star Adelle shocked the world after revealing her jaw-dropping transformation. On her birthday Instagram post last month, the 32-year-old singer was completely unrecognizable after losing a whopping 44 kilograms.

Because of this, people started wondering about Adelle's diet and weight loss program. According to reports, the "Someone Like You" singer followed the "sirtfood" diet throughout her journey. 

Sirtfood diet strictly follows a 1,000 to 1,500 calories intake per day and eating food that boosts a protein called sirtuins such as blueberries, strawberries, turmeric, walnuts, onions, green tea, red wine and dark chocolate. 

Researching online about the sirtfood diet could be a little overwhelming, so we have rounded up the four items you need to kick off your sirtfood journey. All these items are readily available in Amazon, making your diet shopping more convenient.
