The 5:2 fast diet was popularized by TV presenter and medical journalist Dr Michael Mosley for its health benefits and weight loss.
Based around Intermittent fasting, it recommends you eat well for 5 days a week, and then reduce calories to 500 (for women) or 600 (for men) on 2 non-consecutive days.
The good bits
- As you would expect from a book written by a Doctor, the science and background to the benefits of fasting are well researched, well communicated and generally excellent.
- There are lots of good tips for making the program work, along with personal examples making it feel more human
- Includes recipes and ideas of meals for the fasting days
- Author’s experiences add to its accessibility, making you feel that if they can do it so could you.
Not so good bits
- My main issue is that it isn’t real fasting if you are eating 500 calories, and as a result you are missing out on some of the fat burning effects by not being fully fasted.
- No real program and relies on its flexibility but suspect some would have preferred a more clearly laid out structure and plan.
- You are still having to faff with counting calories (which can cause confusion especially on the non fasting days – clear when you read Facebook group comments)
- Whilst it talks about eating a low GI diet, it could have focused more on the healthy eating.
- A well written and great introduction to intermittent fasting, but should have gone just a little bit further, and taken its own science to the proper logical conclusion, rather than diluting it.
- Would highly recommend it for first timers, but think with a few minor tweaks it could have been a classic
