5:2 The Fasting Diet

The diet has risen in popularity over recent years due to its simplicity and coverage in various documentaries and studies.

So what is the 5:2 diet?

Based on the principle know as intermittent fasting (IF) where you eat normally at certain times and fast during the others, the plan is quite simple. You eat normally for 5 days of the week and fast on the remaining two.This works by cutting your calorie intake for those 2 days to a 1/4 of their normal level. It is suggested to have between 500-600 calories if you are female or 600-700 if you are male.  The success of this diet relies on not over eating during your normal eating days.

Although is simple and effective, this type of diet does not produce the best weight loss results due to it intermittent nature. So if you are looking for faster weight loss it is recommended that you look at the other Low Calorie Diet plans.

Very happy with the products i really like the bars. I've lost 22lb in 3weeks *


This review is not about losing or gaining weight but more about my satisfaction with this company's products and delivery. Firstly this an genuine response and no mucking about. I am into my third - I think order - and that in itself should tell you something. I suffer from digestive problems but the meals I have had so far have been excellent with no upsets whatsoever and that does include a good cross section of their menu. To say that I am delighted with the meals and delivery is putting it mildly and as I a disabled it makes for an far easier life. Take note those who may be sceptical, try them, I doubt you'll be disappointed after all my last order was £93.00. Believe me you don't spend that if you are not satisfied!!!!! *


I’m doing the women’s keto diet and I have just completed week 1. I have lost 8lbs which is amazing but it has taken a lot of suffering! The main issue I’ve found is that I’m constantly starving, like to the point I’m having trouble sleeping. I can’t understand where in all of the reviews I’ve read, that these products fill you up?! I must be super unlucky! The taste of every product is really tasty and It does feel like a treat drinking a shake or eating a bar which is great. I also bought the fibre powder which I have 3 times a day and at least two litres of water. I did suffer ‘Keto Flu’ during the first week, but that seemed to disappear on day seven thankfully as it was pretty awful. So in summary (my personal opinion) The plan works, the food and shakes are very tasty but they do not fill you up! I personally could not work full time on this diet as I’d keel over or eat someone 🙊 and I especially could not manage the first week being at work on this diet or driving a car as the brain fog is bad lol *


I have only been on it a few days but very impressed with the flavour of the shakes and bars. I am only doing the diet for a short time as I don't have that much to lose, but want to get rid of the summer pounds and back in control *


Everything I have tried has been delicious *

Looking to achieve ketosis?

Woman Keto Diet Man Keto Diet

Unsure what ketosis is? Don’t worry, simply choose our easier to follow regular plans as you will achieve the same great weight loss.

You will see similar rapid weight loss on all our plans. There are only minor differences in the plans, so choose the correct one for your lifestyle.

Whenever you would like! As long as you are consuming all your products and meals evenly spaced out throughout the day it does not matter if you have it for breakfast, lunch or dinner. Find what suits you best.

Weight loss is a very individual thing and is based on your metabolism, starting weight and lifestyle etc. This said very low calorie diets such as this do encourage more rapid weight loss than traditional diets. If you read the reviews and success stories, customers have lost anywhere between 1 and 10 stone.

If you feel the need for a meal one day then simply follow the guidelines for the “with meal” plans. Also if you do not have the time for your meal on the “with meal” plans then simply replace it with another Shake That Weight product. This should not affect you weight loss.

This plan will result in the similar amounts of weight loss as our others. All Shake That Weight diet plans can result in ketosis/release of ketones and offer similar amounts of weight loss to this plan. The difference between this and our other plans is this is less about calorie counting, and more about limiting the total number of carbs you consume a day. It also has more limitations on which meal products you can have and things you can drink than the other plans.
