to think some people overreact about fasting?

I was listening to Dr Rangan Chatterjee’s podcast and he mentioned a few times that whenever he talks about fasting, there is always a bit of a backlash.

He does say quite clearly that it is not for everyone, and that people should do what works for them, but apparently every time he brings it up there is still a pushback and people getting quite upset about it. He didn't go into the reasons why people are reacting this way.

There is a lot of research now supporting the benefits of fasting. Many people of different faiths have been fasting for years so there is good evidence it is beneficial.

Obviously there are exceptions and it will not be suitable for everyone but that is true of most health approaches.

It just made me wonder why it seems to trigger such a strong reaction. No one is being forced to do it and he is not presenting it as a one size fits all solution.

I wonder whether people are getting offended as it may be a willpower issue.

AIBU to think the reaction is a bit over the top?

I eat one meal a day.

I don’t go on about it, but I lost 16 stone and reversed a load of health issues, so people ask me.

It’s like I’ve told them I eat kittens.

I will definitely die from eating once a day. They said nothing when I was pushing 30 stone and cramming greggs into my face all day, but yes, eating one meal a day of unprocessed food is what going to end me.

And when I say they ask me, it’s usually becuase they are accusing me of WLS or jabs, and getting angry because I won’t “admit” to doing something I haven’t. So of course, I have to tell them it’s fasting. Then they tell me I will die or that I have an ED, I can’t fucking win.

I think that some people will hide an ED behind this for sure.

Plenty of people hide behind all sorts of things to hide an ED. That is nothing new. Anything can be abused.

It doesn't stop fasting being hugely beneficial to health.

I think it’s unfair to suggest that sensible fasting encourages eating disorders. If you want to target eating disorders then it’s media portrayals of beauty standards you need to be going after, not fasting.

If fasting encourages eating disorders then so does the gym because many people with eating disorders exercise excessively as a way of trying desperately to lose weight. Should we ban gym memberships? What about weight loss injections? - there are people that abuse them too and lie online to get hold of them so let’s ban them too. They shouldn’t be talked about either.

I find it bizarre that people are focusing only on fasting but not other weight loss methods that people with EDs are known use to abuse

I think that is probably the reason for the backlash whenever Rangan mentions fasting. People jump to disordered eating when there are multiple ways people choose to hide disordered eating.

I think dieting is like religion or politics, you should only ever discuss it with people you are 100% sure are on the same page as you

For what it's worth I do intermittent fasting because it helps enormously with my ibs....I think l I've only ever discussed it with a GP though

This.

i have seen posters on her on 72 hr + fasts. Some even for a week.

if gives those with disordered eating an “exuse” to not be eating. I know when I was in the thick of it a massive part was making sure others didn’t think you had a problem. Fasting gives someone a reason to be sitting at dinner with a glass of water with everyone else thinking you’re acting reasonably.

it doesn’t work for me.

That doesn't mean fasting itself is the issue. People with disordered eating can latch onto almost anything. Clean eating, cutting carbs, obsessively tracking calories, over-exercising, lying about having eaten.

The research shows it is hugely beneficial to health and longevity.

Those really long fasts you see mentioned are not what most people are doing day to day. Most people talking about fasting are doing something much more basic and structured.

Sitting at dinner with a glass of water could be a red flag in one context, but in another it’s just someone sticking to a plan they’ve chosen and then eating normally later. You can't make judgements for one snapshot.

The key difference is what’s going on overall. Are they eating properly outside of that window, are they physically okay, is there anxiety or secrecy around food. That is what separates fasting from disordered eating, not just the act of not eating for a period of time.

There might not be from the chap you mentioned but I've had several first-hand experiences of people whanging on about fasting - or whatever other dietary habits they've latched on to - like it makes them the virgin Mary. So when I hear somebody else strike up about fasting, or beetroot juice, or cider vinegar, or whatever else it is, I no longer listen politely for long.

You could say that about anything WLI, keto and everything else people bang on about. Even politics.

The chap in question doesn't bang on about any one thing. He considers a range of different perspectives and then say do what works for you.

Fast or don't fast. It should be a private matter, the oversharing by some is inappropriate.

Many binge rather than fast anyway. Ramadan for example, a massive feast before dawn and a massive feast at dusk. Same calories over a 24hr period just done at different times. It's no hardship.

I think a key problem is that advice to fast, if not properly delivered and understood, can encourage EDs in those who tend towards disordered eating.

I remember doing 24 hour fast for charity as a child in the 80's...

There are no holier-than-thou undertones. It is presented as an option that is backed up by research. It seems to be against the idea of fasting.

SatsumaDog · 17/04/2026 13:33

I think a lot of people think of fasting as something you do for long periods and that it’s a fairly extreme thing to do. In reality, it refers to a huge spectrum of durations. Most people fast for 12 hours every night.

Anything relating to food and its restriction seems to make people emotional. One size does not fit all and even intermittent fasting (16h plus) makes me feel unwell. Each to their own I suppose!

There's some truth in people who think it's normal to eat every day, are greedy?
Fasting is another part of disordered eating. Intermittent fasting, is fine, if it physically suits someone.

Do you realise that many cultures had fasted from the beginning of time?

It’s not all about disordered eating

And there is much scientific evidence that autophagy Is hugely beneficial

Yes but others see that as a disqualifier… that if they don’t say the intermittent part then they don’t mean that type.

As other have asked, are they reacting against the idea of fasting itself or are they reacting against somebody else banging on about fasting, quite possibly with holier-than-thou undertones? There's nothing more boring than hearing about the intricacies of somebody else's diet regimen so while I sort of do the 'intermittent fasting' thing myself - almost inadvertently - I don't feel the need to bring it up in conversation and if anybody else does I very quickly get to 'STFU I don't care you tedious git' stage.

Then you just eat early, to me fasting would be going an entire day or more without calories intentionally. Hence why yours is called intermittent fasting not just fasting.

I don't have any interest in diets or weight loss culture, and "intermittent fasting" always seemed to me to be one of those bonkers borderline-unhealthy things that those people do. The phrase sounds quite extreme. Turns out I occasionally do it accidentally - I can't eat before I go running otherwise I get stomach cramps, so if I don't run until midday I guess I've "intermittently fasted" without realising? I wouldn't do it for its own sake though.

so you think It’s borderline unhealthy, but then admit that you do it
That doesn’t really make sense

There’s nothing remotely unhealthy about having 16 hours for example of not eating

That still leaves eight hours to be eating your food which is enough for anyone

Jellybunny98 · 17/04/2026 13:26

I don’t really care what anybody else chooses to do and have done intermittent fasting before myself but I do think some of the concern with fasting is that it can end up in a binge/restrict cycle which moves into disordered eating.

If you fast for say 16 hours and then just eat your normal breakfast, snack, lunch, dinner etc then that’s great and works for lots of people.

But if you fast for 16 hours and then are so starving hungry that you spend the first 2 hours eating your entire days worth of calories it’s not great and that’s the cycle lots of people fall into.

However that’s true of lots of methods of weight loss really, and exercise, everything taken too far can become negative for someone.

nunamenuyear · 17/04/2026 11:20

I don’t care if people fast or not but those who do often seem a bit smug about it.

Only the smug ones.
you likely wouldn’t know about the non smug ones would you as they’d just be doing it and not talking about it

GoldenCupsatHarvestTime · 17/04/2026 13:19

As can be seen on this very thread. There is a division between those who do not class intermittent fasting as actual fasting and those who do. Which was my very point. It causes agro because people are looking at the topic from different definitions.

Holtome · 17/04/2026 13:19

Intermittent fasting seems like the "right" way to eat to me, what our Grandparents would have done, if you mean 8am breakfast, 5:30pm dinner and no evening snacking. I don't know why there'd be any "backlash" to that.

How? It has so many benefits proven in scientific journals.
