'It combines all the latest thinking about the health benefits of kick-starting your diet with a fast-track 800 calories a day for a few days, weeks or months, followed by a steady — and now much more manageable — 5:2, which allows 800 calories on fast days and healthy eating the rest of the week."
I see it now. You starve yourself on 800 calories for a period of time, THEN you get a reasonable 5:2 plan lol.4 -

the article says a maximum of 12 weeks
Hang on....12 weeks is 3 months = a few months, which is what I said5 -
I've used Mosley's 5:2IF plan in the past and thought he was a pretty solid resource (I've read his older book/watched his BBC fasting documentary a few times and suggested it to others), however I can no longer recommend him to others because I think he's going down a slippery slope and people will jump on his new plan and end up a mess.7

Low intake diets can be ok for *some* people under *certain* circumstances. But as a general rule, they are neither healthy nor sustainable. They do not teach good habits, proper portion control, or balance. IMO, they are not a good option.
5:2 and similar fasting protocols, by in large, are more healthy (nutritional) given the 5 days at full calories, assuming a reasonably balanced diet. And if you are properly managing your intake on the 5 days, then you *should* be learning about portion sizes, balance, etc... so most of the concerns related to VLCD go away (or the risk is minimized) with 5:2 and similar. However, the question of long-term sustainability still comes up, and the answer to that question will probably be very individual.6 -
I apologize in advance! I’m not promoting 800 calories a day. I just read this intermittent fasting article and it mentioned doing 5 days regular eating, 2 days 800 calories so I thought I would ask.6

I've only known one person who did an 800 cal/day diet and that was under medical supervision as part of treating issues beyond just being overweight. I would not choose that route. I do sometimes have days that low, but not lots of them and generally only due to illness or something of that nature.4

That would be 5:2IF and is generally accepted as an ok plan to follow. The key though is making sure you have those higher calorie days mixed in with the lower calorie days. Mosley started out promoting that but has now gone down the path of promoting very low calorie days for consecutive days, for longer periods of time. That's completely different than 5:2IF.4 -
Extremely dangerous to attempt with a team of medical professionals monitoring you.
There would have to be some massive underlying health risk to justify this.
This still fails to address the underlying behavioral aspect and the long term success rate of these programs are abysmal.7 -
My thoughts, based as always on my own experience. Last year when I first started to exercise I didn’t eat back any calories and was eating 1200-1300 calories a day. (Didn’t know better at that time).
Reading through the boards, I figured out what net calories were. lol. Turns out I was netting 800-900 calories most days. I was lightheaded and tired. When I made sure I was netting the correct amount of calories for me those issues resolved and I continued to lose just fine, albeit slower.
Personally, I think 800 calories a day seems unnecessarily low and potentially dangerous unless one is under the direction of a physician. Intermittent fasting, on the other hand, can be very helpful to stay within a healthy calorie intake.

If you are eating 800 calories one or two days a week, and using the saved calories to eat more on the remaining days, that can be an effective strategy, often called 5:2 intermittent fasting. It's generally safe as long as your weekly calorie total is not an overly aggressive deficit. Some people might still have a problem eating that low even for one day, especially anyone with blood sugar issues, so YMMV. Eating too little one day would cause me to overeat like a lunatic the next, but it works for some people's appetite.
Eating 800 cals every day is not safe and should only be done under a doctor's guidance in an extreme situation. It still has it's dangers, which is why you would need to be monitored by a doctor to ensure any dangers are caught early. It would no doubt also require supplementation (again, doctor prescribed) to avoid malnutrition. In general, it's a great way to swap one unhealthy situation (excess fat, obesity related diseases) for another (malnutrition, muscle wasting, hormonal issues, EDs).3 -
Low calorie diets long term are a problem for your metabolism. Women especially who can create hormonal imbalances and thyroid problems. If you are on a deprivation diet to lose weight, it will only set you up for failure and the inevitable yo-yo cycle.6

It is pretty amazing how the human body works. And i'll say it again, not everyone is the same. Sounds like a pretty tough program for most people. Those of us that live in countries where food is readily available are so trained to just eat when and where we want that even missing a day of food makes us want to eat our spouses...per some of the previous posters...funny but goes to show really how much eating is really a mental thing for us now. We don't eat to survive we just eat and its habit. Where am i going with this? I don't know, but it sure made me think...4

Isn't VLCD promotion against community guidelines?
What’s VLCD?
Very low calorie diet. Against the TOS.
What's TOS?
This is why I don't go on forums. People don't use words and then just expect you to know what they mean.
I agree it would have been more helpful if the words Community Guidelines were used and a link provided. So here you go: https://myfitnesspal.com/welcome/guidelines
The relevant guideline is # 6.
Community Guidelines are also referenced in a sticky in the Getting Started forum. https://community.myfitnesspal.com/en/discussion/10041081/welcome-to-the-myfitnesspal-community#latest
A tip for better foruming experiences - read stickies and get the lay of the land before posting.
Hard to link on mobile phones and that term is broadly used so I don't see the difference.3 -
800 calories a day is the reason I have brittle bone disease, nails that peel off in layers and I'm fighting to keep my teeth at the age of 40
They shouldn't be allowed to promote that17 -

That's my thought. Unless you want to end up like Karen Carpenter. (Man, am I showing my age with that reference.)1 -

Aaah - Michael Mosley's "diet of the month".......yeah, I'm sure he's making a ton of money. Mosely doesn't actual Prove anything in his multiple diet books. Look closer, there aren't scientific studies. Just he said, she said.
OP - do you want to lower your body fat %, or do you just want a certain number on the scale? Because a very aggressive weight loss plan will help you lose lots of lean muscle mass.
Very low calorie diets are only recommended for the very obese (they don't lose muscle initially) and are medically supervised with vitamin injections (more effective than pills) and check-ups.
Please when your hair starts to fall out, take that as a sign you aren't eating enough. This is a dangerous practice.4 -
