In this book he brings together all the latest science - including a new approach: Time Restricted Eating - to create an easy-to-follow programme. Recent studies have shown that 800 calories is the magic number when it comes to successful dieting - it's an amount high enough to be manageable but low enough to speed weight loss and trigger a range of desirable metabolic changes. The secret of this new programme is that it is highly flexible - depending on your goals, you can choose how intensively you want to do it. Along with delicious, low-carb, Mediterranean-style recipes and menu plans by Dr Clare Bailey, The Fast 800 offers an effective way to help you lose weight, improve mood and reduce blood pressure, inflammation and blood sugars. Take your future health into your own hands. Review: Fast at first but good. - I bought this book in 2023 and read the first part of it and thought it was just too hard, to restrictive, too everything and tucked it away on my bookshelf. So here i am taking another look. Jan. 1 2025 I was up in weight again so I started doing a 1000cal/day diet of my own and lost 7 pounds in the first week. Second week nothing. So I got this book off the shelf and wiped the dust off and read it again and started the 800 cal/day regimen. Three more lbs down as of today 1/26/25. I'm older so I'm fine with 1-1.5 lbs a week as I have a slow metabolism. It keeps me accountable with some structure and it works with a daily 30-45 min walk. I do mostly low carb and count only protein and calories and aim for 65-70g of protein minimum per day. It's worth a try if you're determined. Review: Best diet approach in decades! - I love this book. About 10 plus pages are dedicated to correctly designed diet studies going on in UK and around the world. If you are in the USA it will make you feel like your government is slacking. Don’t even bother to do the regimen 8 weeks straight, just do it every third day. People are losing significant weight and keeping it off. People are reversing blood sugar issues. They write that Studies show there is no slow down of metabolism when doing “spurts” of dieting. I am Middle Age and nothing was working. Also, I was so close to a normal BMI, only having maybe 10 pounds to lose, I thought that’s why nothing was working. I do this regimen every third day. In other words, I eat 800 kcal one day and eat regular ( I.e. just to maintain weight) the next two days. It works like clockwork. The first day, first meal was a shock but easy after that. I do Slimfast (7 grams) keto coffee with light cream, small. Later is bell pepper and onion sautéed with 2-3 pieces of lunch meat and 5 second squirt of coconut PAM. Snack can be egg drop soup or small Kind bar. Lunch can be lettuce wraps, e.g. lettuce, one slice of cheese divided, 2-3 more slices of lunch meat, 1 teaspoon mayonnaise, misc veg like tomato, cucumber, onion inside the wraps. I use a good three slices of lettuce. At night I have about two hundred calories of meat and more vegetable. I’ve learned to enjoy salad with a about a third of an orange squeezed over it and add apple cider vinegar. I often get in about 40 calories of fat free yogurt and add a couple big strawberries or same volume of other berries. The weight lose is so predictable that it only took me one day to realize I no longer want to gorge on my regular days. For example, on my “regular” day I enjoyed breakfast with a frappe from the coffee shop but took my own mini kind bar instead of buying a pastry. The next “regular” day I did buy fast food chicken nuggets but hauled along yogurt, berries, and salad to round the meal off instead of buying fries and a huge burger. I do still very occasionally enjoy a Happy meal cheese burger on my regular days if I really want to go wild. You get so used to weight loss the morning after your 800 kcal day that you are extremely motivated to go for “maintenance” not “gorging” on the regular days- although you could. My whole world changed after three days. I cleaned my refrigerator out, gladly. I know exactly what I want and need from the grocery and nothing else. My smaller clothes are fitting. My scale is my friend. The only pain in the butt was the very first night. I planned all my next day’s food and wrote out all the calories. It was so worth it because I Picked my favorite healthy vegetable, protein, fats and I just tweak as needed or desired. Why 800kcal? The body is merely tortured with 1200 per day, because it’s not cutting back enough to shut the fat storing insulin down. In other words, insulin is a bit more like an on/off switch not a dimmer switch. Shutting it down allows the body to truly burn its own fat. you always know you can eat “maintenance” the next day so between that knowledge and the knowledge that weight loss is a sure thing you will be successful. Life changing. Check in with your doctor especially if you are on diabetes medication, blood pressure medication, and if you have any other usual conditions. Always good to check anyway. Some drugs have to be cut back on immediately, only your doctor knows for s rue. The book is Mediterranean not low carb, so enjoy your healthy non starchy carbs. I don’t do pasta or bread or potatoes on my diet days, but on my maintenance days I eat them in moderation. You can do this without intruding on your social life.go for it! ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #123,481 in Books ( See Top 100 in Books ) #182 in Weight Loss Recipes #516 in Weight Loss Diets (Books) #772 in Other Diet Books | | Customer Reviews | 4.4 out of 5 stars 15,207 Reviews | ## Images ![The Fast 800: How to combine rapid weight loss and intermittent fasting for long-term health - Image 1](https://m.media-amazon.com/images/I/71BHzwJ9lpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fast at first but good. *by K***T on January 26, 2025* I bought this book in 2023 and read the first part of it and thought it was just too hard, to restrictive, too everything and tucked it away on my bookshelf.

For me understanding the background helps me to "do it". The book itself offers enough information to start, without needing to buy additional (recipe) books. Although if you have a lot of weight to loose I can understand the need to vary your weekly menu. The information is clear. No matter what anyone tells you, dieting will never be easy. And when you go back to your old ways, you will gain back the weight in the end. Changing your diet on the long term is also not easy. Before you start you need to be sure you want to do it. As dr Mosley points out, it is not just willpower. And yes eating satisfying foods help and so does TRE. But you need to sure you are willing to put the work in. And to understand it is a lifechange.. you are not done after 8 to 12 weeks and you can't simply go back to your old ways... As said I enjoyed the book and the explanations. What I found lacking, is that there is no substitution mentioned for ingredients you can't/won't eat. I would not have considered myself a fussy eater, but trying to follow the recipes I actually feel I am a fussy eater. I hate avocado, coconut and most fish. I tolerate chicken and spinach, but I do not want to eat it often... Although I get that the current way of eating is the reason why I am seriously overweight, and that adjustment is needed, somethings are a no go. Stop drinking soda's with sweetners, sure.. Reducing the amount of (simple)carbs, check.. Eating more greens, make better choices in fruit (some have a very high natural sugar content) I get it. Trying out some new "stuff", oke! But for us "fussy" eaters why not add a note with substitutes? Also as some reviewers complain about the cost of the ingredients and the waste.. a weekmenu which uses the same ingredients so you can use them up would be a good addition. In overal a good informative book to read and use. Thank you, dr Mosley, for busting some dietmyths (such as fasting is bad for you) and bringing us factual proof and science on how our bodies work and how we can get healthier! ## Frequently Bought Together - The Fast 800: How to combine rapid weight loss and intermittent fasting for long-term health - The Fast 800 Recipe Book: Low-carb, Mediterranean style recipes for intermittent fasting and long-term health (The Fast 800 Series) - The Fast 800 Easy: Quick and simple recipes to make your 800-calorie days even easier (The Fast 800 Series) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/104657668-the-fast-800-how-to-combine-rapid-weight-loss-intermittent](https://www.desertcart.tn/products/104657668-the-fast-800-how-to-combine-rapid-weight-loss-intermittent) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-20*
