This diet was invented by two nutritionists, Aidan Goggins and Glen Matten, from the United Kingdom. Men studied sirtuins, a group of seven proteins in our body that can boost metabolism. According to the Sirtfood diet, you have to eat only products with a high level of sirtuins to increase their intake, provoke a fat-burning process in your body, and even get anti-aging properties1Libert S, Guarente L. 2013. Metabolic and neuropsychiatric effects of calorie restriction and sirtuins. Annu Rev Physiol. PMID:23043250.

The Sirtfood diet is not for the faint-hearted because it has a lot of strict restrictions. You can eat only 1000 calories daily for the first three days: two glasses of green juice and one meal. For the rest of the week, a person on a diet can consume 1500 calories daily. But the fans of this diet say these severe limits allow you to lose about 3 kilos in one week.

Here is a food list that you can consume: kale, Medjool dates, apples, strawberries, blueberries, buckwheat, capers, citrus fruits, olive oil, walnuts, green tea, red onion, soy, arugula, parsley, and - surprise! - red wine and dark chocolate.

Rebel Wilson

One more champion in losing weight is the Australian actress Rebel Wilson. For one year, she slimmed down to 35 kilos. How? Here are the answers.

In 2019 doctor said to Rebel that she has the polycystic ovarian syndrome, which is why she has to lose weight to become healthier and, as a result, increase her chances of getting pregnant. To gain these goals, Rebel chose the Mayr method diet. The main principle of this approach is related to a healthy gut system and foods that help to massage digestive systems.

Firstly, Hudson decided that less means more. Instead of long hours of exhausting workouts, she preferred daily 30-minute walking, and later she added her favorite sports like jogging, cycling, and tennis.

But the main secret of her good shape is the portion control method. Hudson cares a lot about the foods that she puts in her body. She eats small portions three times daily and ensures that each meal consists of an amount of protein combined with vegetables or fruits. Hudson doesn't eat junk foods for snacking; she prefers something healthy like apples or celery sticks. Mindful eating is the key.

The plant-based diet can help you lose weight because it is rich in fiber, so you feel full without extra calories. Furthermore, the plant-based diet reduces the risk of chronic diseases like type 2 diabetes, heart disease, and kidney disease.

It can be challenging to give up meat, but the modern world provides diverse food choices whereby you can find a better and healthier replacement. In the beginning, you can replace milk with plant-based ones like oat milk or almond milk; to change meat in your ration, choose meat substitute products. Don't forget that your plant-based diet has to be nutritious and include all essential vitamins and minerals from grains, nuts, vegetables, and fruits.
