Sirtfood diet review

Is the Sirtfood Diet sustainable over a long period of time? Or is it better to just do a week of it and then return to your normal eating habits? A Sirtfood diet review.sirtfood diet review

The Sirtfood Diet is all about re-discovering the true meaning of the word ‘diet’. Not some trendy means to lose weight at any cost, but a sustainable way of eating that reaps lifelong benefits. It’s about incorporating the best foods nature has to offer into a way of eating that fits into daily life, works for the whole family, and keeps the body in perfect balance long after the initial hyper-success phase of the diet.

We know that the only successful diets in the long run are diets of inclusion, not exclusion. With that principle in mind, one of the things we love is the idea of ‘sirtifying’ your meals. That means taking some of our most cherished dishes and giving them a Sirtfood twist. Chicken curry, chilli-con-carne, pizza and pancakes are all possible, retaining all their great taste, but with heaps more goodness thanks to some simple swaps and Sirtfood inclusions.

How is the Sirtfood Diet different to other diets? A Sirtfood diet review.
It is common for participants to actually gain muscle, leading to a more defined and toned look. That’s the beauty of Sirtfoods; they activate fat burning but also promote muscle growth, maintenance and repair. This is in complete contrast to other diets where weight loss typically comes from both fat and muscle, with the loss of muscle slowing down metabolism and making regaining weight more likely.

Unlike conventional diets, participants rarely felt hungry and don’t suffer energy lulls.  Usually they are brimming with energy.

But what really marks out the Sirtfood Diet as special is that it’s all about what you put onto your plate, not what you take off. It’s about eating the foods you love not cutting foods out or demonising whole food groups. Forget calorie counting, forget low carb, forget low fat, and forget strange food restrictions. Dark chocolate, curry, and coffee are all very much on the menu, along with a host of other genuinely tasty foods. It’s a highly effective way of eating for people who enjoy their food.

Vegans and Vegetarians

While vegans and vegetarians can obtain all the benefits from a Sirtfood-based diet, attention needs to be given to the nutrients that may be lacking and appropriate food choices or even supplementation may be necessary. Without animal protein to complement Sirtfoods there is a risk of nutritional vegans and vegetariansdeficiency.
These are the areas for those on a plant-sourced diet and trying the Sirtfood Diet may need to consider for additional assistance.
-omega-3 fatty acids
-vitamin B12
Vegetarians and vegans are usually well-aware of the research into the possible deficiencies in their choice of foods.


Sirtfoods compatible with other diets?

Sirtfoods are not only compatible with all other dietary approaches  but will,in fact greatly enhance their benefits in health and weight. This applies to diets like intermittent fasting,low-carb,paleo and gluten-free which are currently very popular.sirtfoods

Eating a diet rich in Sirtfoods means that the calorie restriction of intermittent fasting can be less severe,yet the benefits will be the same if not greater. A 7 day benefit rather than just say  5 on the 5:2 intermittent fasting regimen.

Low-carb diets that lack plant-based foods can be dramatically enhanced by the inclusion of Sirtfoods. The vast majority of the top 20 Sirtfoods are low in carbs.

Sirtfoods are archetypal paleo foods,containing the sirtuin-activating polyphenols that people have been eating and reaping the benefits from over countless years. Sirtfoods are a missing piece of the paleo philosophy.

The top 20 Sirtfoods are naturally gluten-free making them advantageous  for anyone following a gluten-free diet.

Drinking Green Tea

Like it or loathe it drinking green tea is an essential and core part of the SirtFood diet.

If you’re already a convert to green tea, then congratulations you’ll already be reaping the benefits of the extraordinary sirtuins found in green tea. You’ll find weight-loss comes more easily, together with a revitalised spirit and glowing skin.

Why is drinking green tea so vital?drinking green tea

Green tea is the only source of one of the most powerful sirtuin bioactives, catechin. Catechins are so potent that only a small quantity, one small cup, triggers fat metabolism and reduces oxidative stress.

•    Appetite suppressant

With a cup or two of green tea inside you. you really notice the difference in terms of hunger pangs. You should find that you don’t think about food between meals.

•    A little bit of caffeine

A cup of green tea contains about a quarter of the caffeine you’d find in a cup of coffee or half the caffeine you’d find in a cup of black tea. This caffeine is just enough to combine with the catechins to have an even more powerful fat-burning effect. This is the optimum way to convert fat to muscle.

• More energy

Hard to measure but definitely there, the catechins give you a little natural buzz that makes starting the day a little easier.

• Cumulative effect

The power of green tea keeps on giving and two cups of green tea is better than one cup, three cups is better than two cups.  In fact you can get up to four of your SIRT 5 a day from drinking green tea if you have four or more cups.

• Zero calorie

Green tea is naturally calorie free. It doesn’t need sugar or sweetener and gives you energy without the calories.

Getting Enough Sirts


Are you worried that you are not getting enough SIRTs into your diet? Perhaps you have a passionate dislike for kale? Don’t worry, there are many different ways to get your daily SIRT requirements. So if there is a food or two you want to avoid, then just steer clear, there are many other options. Have a look through this guide  and see what your favourites are.

Think about your green vegetables -ideally one to two portions daily. If you don’t like the stronger tasting leafy greens, then perhaps plainer broccoli or cauliflower? You only need a handful of parsley (10g) and it has a mild, unobtrusive taste. You could buy a growing pot of parsley from the supermarket and add a portion to your main meal or a salad.

Olive oil and olives – at least one portion a day. Olive oil is such a versatile oil that it can be used in virtually all your cooking. Use extra virgin olive oil in salads and a light and mild version for frying when you don’t want an olive oil flavour.getting enough sirts

Onions and apples – at least one portion a day. Raw red onion is great in salads or salsa. Many a main dish starts with lightly sauteed onions. And what could be easier than grabbing an apple as a mid-afternoon snack?

Resveratrol: red wine, red grapes, chocolate – at least two portions a day.

Turmeric – at least two portions a week. You only need 1/2 tsp to get a portion of SIRTs from turmeric. Easy to add to Indian and North African dishes.

Oily fish – at least two portions a week. Salmon, trout and mackerel all count. Salmon is especially versatile and is very quick to cook. Or try a nice breakfast of smoked salmon and scrambled eggs.

With all these normal everyday foods, it is very easy to increase the amount of SIRTs you eat each day. A few wise decisions will pay huge dividends.

Latest SirtFood Research

The research goes on with SirtFoods and Sirtuins. Here are two recent studies.sirtfood research

Resveratrol found in red wine could help counteract the negative impact of high fat/high sugar diets-SirtFood Research

Red wine lovers have a new reason to celebrate. Researchers have found a new health benefit of resveratrol, which occurs naturally in blueberries, raspberries, mulberries, grape skins and consequently in red wine. Resveratol is considered a sirtuin activator.

While studying the effects of resveratrol in the diet of rhesus monkeys, Dr. J.P. Hyatt, an Associate Professor at Georgetown University, and his team of researchers hypothesized that a resveratrol supplement would counteract the negative impact of a high fat/high sugar diet on the hind leg muscles.* In previous animal studies, resveratrol has already shown to increase the life span of mice and slow the onset of diabetes. In one study, it mirrored the positive effects of aerobic exercise in mice, which were fed a high fat/high sugar diet.

While these results are encouraging, and there might be a temptation to continue eating a high fat/high sugar diet and simply add a glass of red wine or a cup of fruit to one’s daily consumption, the researchers stress the importance of a healthy diet cannot be overemphasized. But for now there’s one more reason to have a glass of red wine.

Decreasing the Risk Of Chronic Disease-SirtFood Research

There is growing evidence that sirtuin activators may have a wide range of health benefits as well as building muscle and suppressing appetite. These include improving memory, helping the body better control blood sugar levels and cleaning up the damage from free radical molecules that can accumulate in cells and lead to cancer and other diseases.

‘Substantial observational evidence exists for the beneficial effects of the intake of food and drink rich in sirtuin activators in decreasing risks of chronic disease,’ said Professor Frank Hu*, an expert in nutrition and epidemiology at Harvard University in a recent article in the journal Advances In Nutrition.

Although sirtuin activators are found all through the plant kingdom, only certain fruits and vegetables have large enough amounts to count as SirtfFoods. Examples include green tea, cocoa powder, the Indian spice turmeric, kale, onions and parsley.

Many of the fruit and vegetables on display in supermarkets, such as tomatoes, avocados, bananas, lettuce, kiwis, carrots and cucumber, are actually rather low in sirtuin activators. This doesn’t mean that they aren’t worth eating, though, as they provide lots of other benefits.

The beauty of eating a diet packed with SirtFoods is that it can be more flexible than other diets. You could simply eat healthily adding some SirtFoods on top. Or you could have them in a concentrated way as recommended in the SirtFood Diet plan.

5 SirtFoods Daily

Eat 5 or more portions of SirtFoods daily, consuming the greatest variety of SirtFoods possible.sirtfoods daily


Even when choosing foods from the ‘Top Twenty SirtFoods’ list it can be hard to gauge how much we need to eat for a portion. Is a pinch of turmeric enough? Do I need to eat a whole bowlful of kale? And if I just eat five chocolate biscuits that’s my SIRT 5 a day sorted? Right? Not exactly … but it’s not rocket science either. For example, one cup of green tea is a portion, 30g kale (that’s a handful to you and me) and ten red grapes constitute a portion.
In other words, the amount you would eat as part of a balanced meal is more often than not a sensible portion size.

EXAMPLE MENU 1-SirtFoods Daily


1 cup green tea, 10 red grapes, cereal of your choice

2 of your SIRT 5 a day

• • •


Kale and Stilton soup

3 of your SIRT 5 a day

• • •


Beef and broccoli

2 of your SIRT 5 a day

TOTAL: 7 portions of SIRTs a day

EXAMPLE MENU 2-SirtFoods Daily


1 cup green tea, green omelette made with shallots and parsley

3 of your SIRT 5 a day

• • •


Brie and grape salad lunchbox

4 of your SIRT 5 a day

• • «


Grilled chicken with lemon and olives

2 of your SIRT 5 a day

TOTAL: 9 portions of SIRT 5 a day

By choosing the foods that are rich natural sources of SIRTs, it is very easy to get your SIRT 5 a day. To boost your SIRTs even more, just add simple snacks like an apple (1 of your SIRT 5 a day), a few squares (30g) of dark chocolate (1 of your SIRT 5 a day) and it soon adds up.

More than 5 a day-SirtFoods Daily

The SIRT 5 a day is a great way to make sure you are getting enough daily SIRTs and it is a building block you can come back to again and again to make sure you and your family are getting the fantastic benefits of SIRTs.

If you are about to follow The SiftFood Diet Plan and want to actively lose weight following the plan, then the SIRT 5 a day is a minimum baseline. As you follow the diet you should be doing everything possible to boost your SIRTs beyond 5 a day, preferably towards 10 a day and beyond. If this sounds hard, then don’t worry – all the recipes and details you need to do it are here. The SirtFood Diet Plan guides you with meal planners and recipes to really make sure you are optimising your weight-loss and moving to a good,healthy diet.

Sirtfoods Or Supplements



Sirtuin activators and sirtfoods are very new to the science of nutrition. A ‘sirtfood’ is actually a food high in sirtuin activators.  Vitamins were discovered more than 100 years ago, antioxidants 50 years ago and sirtuin activators just over ten years ago.

The first sirtuin activator identified – and still the best known – was resveratrol, found in the skin of red grapes (which is why red wine is believed to keep you healthy), pomegranates and Japanese knotweed.

Other sirtuin activators soon followed, such as catechins (found in green tea and thought to work against cancer cells) and epicatechins in cocoa powder (responsible for the health benefits of dark chocolate).

But research really took off when the pharmaceutical giant GlaxoSmithKline bought the rights to produce synthetic versions of resveratrol for £462 million. It excitedly trialed this as a cancer treatment but the results were not impressive. In 2010 the company announced that it had stopped the research.

But it now seems eating sirtfoods naturally rich in sirtuin activators may be a healthier, more effective – and cheaper – alternative to supplements. This was the thinking behind the many recent trials of sirtfoods and the sirtfood diet.   Present results indicate that sirtfoods target exactly the same pathway for losing weight and staying healthy as calorie restriction and exercise.
