The Big Crash Diet Experiment

Friday 1st June
The Big Crash Diet Experiment Who saw Wednesday’s show? Wow, what an amazing achievement each case study not only met but exceeded their targets, losing 10% (more for some) of their body weight. The biggest revelation was the impact their weight loss had on their health! It was astounding to see within 9 weeks how quickly your health can be turned around, to the extent of reversing one of the case studies type 2 diabetes.

There is often a fear factor surrounding meal replacements, are they good for you? Will they fill me up? Is it full of sugar?

Professor Susan Jebb (Former Government Advisor on Obesity) stated ‘You are more likely to have a more nutritionally complete diet by taking one of these specially prepared formulae than if you try to assemble yourself, of course you can assemble yourself but it is very hard to get it right.’

SlimFast have worked tirelessly to create products that are nutritionally balanced and tasty - products that we can be proud of! We wanted to deconstruct our NEW SlimFast Vitality ready-to-drink shakes to showcase their nutritional content…

At only 210 calories, these babies contain no added sugar, 26 grams of protein, 23 vitamins and minerals and are high in fibre. Each contain biotin, chromium and iron. Biotin helps energy yielding metabolism (makes you feel more energetic), chromium helps to maintain blood sugar levels and iron helps to reduce tiredness. They are also gluten and lactose free! Our Choc Caramel shake contains green tea extract and our Berry Blast contains real fruit puree.
Check out our full range to find your favourite!



Our SlimFast 3.2.1. Plan is simple to follow; each day you can have 3, 100-calorie snacks, 2 meal replacement shakes or bars and 1 balanced meal a day (600 calories for women and 800 calories for men). It’s flexible and convenient, you can swap meals around each day as long as you stick to the 3.2.1. For example, if you are going out for lunch with a friend why not have your 600-calorie meal then and have a shake or bar later?

Today sees the start of our #30DayChallenge, so why not give it a go and see what you could achieve? Be sure to follow us on Twitter, Instagram and our closed Facebook Group – we will be posting tips, motivation, recipe ideas and much more for the next 30 days to help you reach your weight loss goals.

Body Mass Index (BMI) is a calculation that uses your height and weight to determine a number that represents your risk for obesity-related health conditions such as heart disease, hypertension and diabetes. The higher your BMI is over 25, the greater the risk of developing these conditions.**

**There are some limitations to the Body Mass Index calculation, because it does not measure body composition. BMI overestimates body fat in persons who are very muscular and it can underestimate body fat in persons who have lost muscle mass (e.g., many elderly). People with more muscular builds may be classified as overweight according to BMI numbers even if they have a very healthy body fat percentage. A high BMI from increased muscle alone is not associated with health risks. These are the recommended classifications for BMI, adopted by the Expert Panel on the Identification, Evaluation, and Treatment of Overweight & Obesity in Adults, and endorsed by leading organizations of health professionals.
