25 Oct What Are Sirtfoods? And Can The Sirtfood Diet Help You Lose Weight?
Back in 2015 we were introduced to the concept of ‘sirtfoods’ and their potential for promoting weight loss. The Daily Mail covered the story of a woman who claims she saw significant reductions in her body fat by eating more foods known as ‘sirtuin activators’ or sirtfoods. So what are sirtfoods? And can they really help improve your health and support weight loss?
As with all new diets, you are more likely to find success if you have the support of a qualified nutritionist. You can book a complimentary consultation call with us today to find out if we can help you reach your goals.
WHAT ARE SIRTFOODS?
‘Sirt’ is short for sirtuins. Sirtuins are a class of proteins important for regulating biological pathways that can affect our health and weight. ‘Sirtfoods’ is a term applied to foods that contain naturally occurring compounds that have the potential to activate sirtuins.
HOW DO THEY WORK?
Research has shown that a very low calorie diet may prolong our lifespan. It’s understood to do so by decreasing the activity of pro ageing pathways as well as encouraging DNA repair. It’s believed that sirtuin activators in food may mimic the same effects as a calorie restricted diet. Sirtuins also have a role in fat metabolism which explains why they may help us to lose weight.
HOW MIGHT THEY HELP YOU LOSE WEIGHT?
Studies have shown that sirtuin activators can help mobilise our stored fat and increase mitochondria function (the part of a cell that generates energy). They’ve also been shown to regulate insulin production – the hormone that helps regulate our blood sugar levels and carries glucose from our bloodstream into cells. That said, let’s not forget that the woman in the Daily Mail article was also on a 1000 calorie per day diet which may also have something to do with her weight loss! Early research shows that sirtuins could play a role in promoting fat loss. That said, it’s too early to really call them a wonder food.
HOW ELSE MIGHT THEY BENEFIT YOUR HEALTH?
Sirtuins have not only been been linked to how our bodies metabolise energy, they’re also known to affect the ageing process and the onset of certain diseases. Research into sirtuin activator resveratrol – the beneficial compound in red wine – found that it may help in the prevention and treatment of obesity and help to prevent age related heart and brain deterioration.
It is worth noting that much of the research carried out has looked at supplemented levels of polyphenols. These were usually much greater than we would find in food alone. As further research is carried out we will learn more about the positive effects of sirtuin activators. We’ll also become more aware of the levels beneficial for health. However, all foods containing sirtuin activators are natural, healthy, plant based foods and you can’t go wrong with increasing these in your diet.
WHAT ARE THE BEST SIRTFOODS?
Foods that contain sirtuin activators include:
Olives and extra-virgin olive oil
Tofu and other soy products
HOW CAN YOU GET MORE SIRTFOODS INTO YOUR DIET?
One of the easiest ways to introduce these foods into your diet is by starting with a smoothie for breakfast. Blend together a scoop of quality protein powder, some unsweetened almond milk, a large handful of blackcurrants and some kale.
Add olives to salads and roasted mediterranean vegetables and swapping less healthy savoury snacks like crisps.
Dress salads with olive oil instead of your usual salad dressing. Note that it’s best to not cook with olive oil as it can degrade at high temperatures.
Try swapping regular tea for green tea. If you find green tea bitter you can opt for jasmine tea which tends to be milder. Green tea can also be drunk cold. During the summer months, make a pitcher of green tea and add slices of lemon then keep in the fridge.
Miso soup makes a good afternoon snack. Buy sachets (such as MISO Tasty) or grab it ready made from Pret a Manger or Itsu.
