A ‘sirtfood’ diet is actually one containing foods high in sirtuin activators. Sirtuins are a type of protein which protect the cells in our bodies from dying or becoming inflamed through illness, a research has also shown that they can help regulate your metabolism, increase muscle and burn fat.
The diet is divided into two phases; the initial phase lasts one week and involves restricting calories to 1000kcal for three days, consuming three sirtfood green juices and one meal rich in sirtfoods each day. The juices include kale, celery, rocket, parsley, green tea and lemon. Meals include turkey escalope with sage, capers and parsley, chicken and kale curry and prawn stir-fry with buckwheat noodles.
From days four to seven, or the maintenance phase which lasts 14 days where steady weight loss occurs, energy intake is increased to 1500kcal comprising of two sirtfood green juices and two sirtfood-rich meals a day.
By restricting calorie intake to 1,000 calories and exercising at the same time will always cause weight loss. In the first week of extreme calorie restriction, only about one-third of the weight loss comes from fat, while the other two-thirds comes from water, muscle and glycogen. As soon as your calorie intake increases, your body replenishes its glycogen stores, and the weight comes right back.
Foods in Sirtfood Diet
The Sirtfood Diet plan popularly followed be Adele, Jodie Kidd, Lorraine Pascale and Sir Ben Ainslie focuses on upping the intake of healthy sirtfoods.
These include the following:
- Citrus fruits
- Red wine
- Dark chocolate
- Medjool dates
- Green tea
- Olive oil
- Red onion
- Another top sirtfood is coffee.
On the contrary, by adding sirtfoods to your regular diet over the long-term may very well be a better idea. Eating balanced regular meals made up of low GI foods, lean protein, fruit and vegetables and keeping well hydrated is the safest way to lose weight.
