So, What is the Sirtfood Diet??
The newest addition to the many diets making the headlines is the Sirtfood diet. According to those behind the diet, the Sirtfood diet not only leads to weight loss, but can also offer other more important benefits. In particular, the diet, which allows people to consume red wine and chocolate, can “stimulate rejuvenation and cellular repair.” Nobody will say they do not like that.
The Sirtfood diet is focused on everyday ingredients that nutritionists and experts say can turbocharge weight loss and help you to live longer by mimicking the effects of fasting and exercise. They are foods that are high in sirtuin activators, sirtuin being a class of proteins in the body that are important for regulating biological pathways affecting our health and weight.
The diet is a calorie-based diet. For the first three days, those brave enough to undergo the diet are only allowed to consume 1,000 calories per day consisting of three Sirtfood green juices and other “Sirtfoods.” After these grueling three days, their calorie intake can increase to 1,500. They are allowed two juices and two meals.
Does it work??
In simple, yes. While little is known about the science behind the Sirtfood diet and the relevance to sirtuin activators, sticking to the Sirtfood diet will produce results. If you restrict yourself to 1,000 calories a day and then follow a rigid eating plan you will benefit from a drop in weight on the scales. A more relevant question would be, is it healthy?
Experts surmised that the diet is not healthy and sustainable. The weight lost can easily be retained. The Sirtfood diet should be consigned to the fad pile – at least from a scientific perspective, the experts concluded. They also asserted that the diet might lead to rapid weight loss at first, but it can end up to be “misleading and damaging.”
It is also unlikely to benefit people who are obese and at risk of diabetes. They still, surprisingly, recommend working out and eating a balanced diet.
What should I do??
The takeaway from all this, for me, is that elements of the diet are good. The science behind it may be proven correct over time. However, limiting yourself to 1500Kcal and rapid weight, not fat, loss are two things that contradict everything that I believe and try to educate my clients in. Of course including foods such as prawns, salmon, blueberries and kale in your diet are going to have health benefits. But where are the carbohydrates? Where is your long term energy going to come from?? Realistically the diet will just lead to even more yo-yo dieting.
In summary rapid weight loss and macronutrient deprivation are not the keys to leading a sustainable healthy lifestyle. Aim for continual weight loss, ideally 0.5kg per week, and to consume a variety of non processed foods from a variety of food groups.
Leave the faddy diets to the celebrities.
