  • There seem to be thousands of different active topics but I can’t find one specifically aimed at simply recording how long people have managed to keep following the Fast Diet regime and how successful, or otherwise, it has proven for them.

    There was a negative article by Jonathan Leake in the Sunday Times on 31/12/2017 where a quote was included stating “…there is no evidence to show it (i.e. intermittent dieting) helps achieve weight loss lasting years or even months”.

    Well, if anyone is interested I have just over 5 years of data to show that in at least one case there is precisely that evidence. From memory the Horizon programme that first discussed 5:2 was in Summer 2012, just after the London Olympics. I began my Fast Diet regime about 6 months later, on Sunday 3rd February 2013, after my wife was also convinced it was something we should try. I’ve been doing it ever since.

    I don’t especially want this topic’s thread to replicate the many others from people describing what’s worked for them, or what their concerns are, or what they ate yesterday etc. I’m simply interested in knowing how many other people have managed to keep doing this for at least 5 years and what their long term results are.

    The next thread will be my basic results and no more. It is likely it will be my last post until another year has passed. In 5 years I might create another topic called “10 Years or more on a Fast Diet regime?” along exactly the same lines.

    Hope this table format survives the submission process. My results are:

    Mr Data, good losses on your part! Well done.
    My husband and I have been on this since April of 2013. You have us beat by a month. We still Fast twice a week at 600 calories/day. We are maintaining our losses. Husband lost 45 pounds, I was keeping him company and got to my target weight and then went to a weight which is even lower and where I want to stay. Haven’t seen this weight since 8th grade! My BMI is in the 18 range, which is considered too low but my doctor thinks I am very healthy and she approves.

    Well done fasting_me and your husband,

    You’ve lost more than me. I still 5:2 it as well, 6:1 didn’t work for me. I got down to a weight I hadn’t seen since I was 12, but it’s crept back on a little since then. I suspect I’m not being quite as disciplined as I originally was on the 2 fasting days – although in the last 2 years both in-laws dying, a double knee op, a redundancy and currently a twisted ankle and sciatica possibly haven’t helped. Still, as Churchill apparently used to say KBO.

    Seems like there aren’t many, who log into this website anyway, who have kept going for 5 years, unless they haven’t spotted this topic, or are just keeping quiet.

    There is a chat for Maintainers, where you will find several others who have reached their targets.
    You’ve had a lot to deal with, Mr Data, but you keep calm and carry on. Good work.

    I’ve only been fasting for about 18 months, but this is working for me. I’m down about 5kg since starting 5:2. My weight loss is slow because my focus is more on building strength and lean body mass than losing weight. With calorie restriction and too much cardio I was losing lean body mass and actually gaining fat. It took me years to get there, but it was a sad state of affairs. Fasting has been the cure for that. There seem to be some people that make the eat less move more work for years, most don’t succeed at that. These days I focus on fasting and nutrition and that is working well for me. Right now it looks like I’ll be doing this for at least another 3.5 years … I get to the 5!

    I started with the eat less move more over six years ago and when it was failing me, 5:2 brought me back on track. My peak weight was 106kg, now I’m in the low 80’s, sometimes high 70’s.

    Hi @mr Data

    I started 5:2 in 2013 and I intend to keep this WOL going forever! Sadly though I only found this great online forum in Feb 2017, so I don’t have a ton of data online.

    During these 5 years, my BMI has gone from just over 22 to hovering at or just under 20.

    Sometimes I don’t fast for a month, sometimes I only do 6:1, sometimes I just do 16:8 – it just depends.

    Happy fasting!

    7 year check-in with updated stats:

    Date: 3/2/13, 3/2/14, 3/2/15, 3/2/16, 3/2/17, 3/2/18, 3/2/19, 2/2/20
    Kg: # # 94.3, # 77.6, # 78.1, # 79.8, # 81.9, # 81.0, # 82.4, # 80.7
    BMI: # 27.0, # 22.2, # 22.3, # 22.8, # 23.4, # 23.2, # 23.6, # 23.1

    still KBO’ing.

    This posting is pretty old

    I am 6 years and 4 months into 5:2 IF

    Down 100# (-90 <> -107 since year 2.4)

    Started at 274# – Now solid in the 170<>180 range

    VERY pleased and happy to continue 5:2 IF?

    You betcha !

    I’m working on my fourth year of 5:2 fasting. I mostly water fast, but I do sometimes do longer fasts and I have skipped fasting sometimes.

    1) No real problems with weight. I tend to stay in a 78kg to 82kg range. (6 years ago I was at 106kg.)

    2) Continuing to slowly lean out. Fat seems more loose where I have it and it comes and goes quickly.

    3) Gaining slowly in strength and muscle which is a big deal at 60.

    4) Fasting is getting easier all the time, often if feels better than eating. (Seems strange, but I’m into feeling well.)

    Maybe everything will go to pot next year, but at least the 4th year seems good for me!

    Been an avid follower of this WOL since watching the original programme on TV during the 2012 olympics. Tbh there are times when I follow it less closely but even when not sticking to the full regime it has influenced my eating in a positive way. 4:3 works best for me Mon/Weds/Friday, giving me the weekend to relax and enjoy life lol.
    My weight 8 years ago and body shape were bad and god knows what kind of a state I’d be in now if I hadn’t stumbled upon this.
    In regards to tips the biggest thing is ‘DON’T focus on the fact you can’t eat when you’re in the midst of a fasting day ‘mind crisis’ focus on the fact that tomorrow morning you’ll wake up feeling GREAT can ENJOY a decent breakfast . The other thing is hunger doesn’t build and build, it comes and goes in waves, a glass of water, a coffee or even some DIY and the hunger soon goes.
    Like I said I don’t always stick to it as rigidly as I did almost religiously for the first 5 years nowadays but I range from 35-45lbs lighter than I was in 2012, my immune system is much much stronger, my cholesterol levels and blood pressure are much lower than they were and my body shape has never reverted to the blob I was
    Here’s to the next 8 years 😊

    Been following the fast diet for about 5 years. Fairly strictly for the first 8-9 months & then just the general principles.
    Blew through my target weight in 3-4 months & settled on my current range of 160-165 lbs, BMI ~22 (started at 185 lbs). My tastes & body adjusted to the new weight range fairly quickly & I have modified my regime as I read research & moved away from the recommended North American food guide. I find it easier to do either 24 or 36 hr fasts with the occasional longer fast thrown in for the health benefits. I don’t eat snacks & often skip breakfast or lunch if I’m not hungry. I don’t count calories anymore but tend to eat fewer carbs then before. I don’t avoid animal fats but do avoid/limit sugars/artificial sweeteners & vegetable oils.

    8 year check in and still 5:2ing OK.

    BMI target is 22.5, Over the years it has been:-

    2013 Average 23.2 (21.6 – 27.0)
    2014 Average 22.2 (21.6 – 23.0)
    2015 Average 22.8 (22.2 – 23.6)
    2016 Average 23.1 (22.2 – 23.7)
    2017 Average 23.3 (22.7 – 23.9)
    2018 Average 23.2 (22.1 – 24.1)
    2019 Average 23.0 (22.4 – 23.6)
    2020 Average 22.4 (21.9 – 23.2)

    Today 22.7

    More time to do a long daily walk in 2020 thanks to lockdowns and furlough periods.

    Great work Mr Data keep up the good work!

    Thanks Iona.

    Hello All,

    I’m back

    It’s been two more years, so now in my 8th year and I am still using 5:2 IF in my life, and I continue to lose small amounts of weight – My best in the last 3 days = 168#, and my target was 165#, this after weighing 274# in late 2012

    8 years later, and I am STILL enthusiastic about my program – It’s been a stunning success in my life, and I won’t let it go

    Well done Trajan, amazing results too!!!!!
    And along with all that weight loss there’s all the other health benefits to the immune system etc (as in your other post in the science thread.
    Keep it up mate and Good luck!!!

    Well done Trajan.

    Ive been doing 5:2 since 2015. I lost around 30 pounds after about 6 months, and maintained that for the next 6 years or so. Then the pandemic hit and I took a couple months off, and gained 10 pounds back, and then started back up in May ’21, but the problem is since I have started back up I am not loosing weight like I did before. not sure what to do differently.

    Hi Innerphaze,
    I’ve found the same in that losing weight through this isn’t as easy after a while. It still happens but the magic way my spare tyre disappeared is a thing of the past.
    I’m no scientist but there’s been quite a lot of research around the body reacting to calorie restriction by burning less calories in the long run. That’s a simplified explanation and whether that’s right or whether it applies to alternate days of calorie restriction I don’t know.
    On a similar note to your point, I’ve been doing 5:2 or 4:3 since 2012 but when the lockdown happened (and at various other occasions) I’ve drifted away from strictly adhering to it. Recently I’ve started wearing a whoop strap, it measures HRV, which is supposed to be a good measure of the health of your autonomic system. Also your resting heart rate and respiratory rate which again are good guides to your health.
    I’m a 54 year old male with mild COPD but a keen cyclist, my stats produced (the strap sends the results of the stats to your smartphone) have been up and down but nothing special.
    …then on Sunday I did my first fast since Spring, mainly because I’ve been having some stomach problems, I didn’t really expect it to have a massive effect on my health markers. But Monday through to Wednesday my stats were amazing my HRV was the highest it’s ever been and my resting heart rate was down to 52bpm. Tried it again on Thursday to see whether anything would happen…and again there was a massive further spike in my stats. My HRV has doubled from a few instances a couple of weeks back and hit another high, additionally my resting heart rate was 48 today.
    So in short, personally I think the weight loss effect of this WOL is not as effective, though it still works, after an extended period of time. But the health impact could continue for longer.

    Though as I said, I’m no scientist.

    Good info on the health benefits.

    Back in 2013/14 after 6 months of 5:2 and having lost all the weight I wanted to I switched to 6:1 for about 8 months but the weight crept back up and when I switched back to 5:2 the weight didn’t come off again nearly as fast as it had in those first 6 months – in fact I’ve never got back down quite as low again, although I did change my target to be a bit higher at a BMI of 22.5, instead of down at 21.6 which was the minimum I got too (when some people said I looked too thin).

    I chose 22.5 as a wide ranging health analysis at the time, looking at loads of different studies, indicated it was the healthiest weight across a range of factors including the immune system’s ability to fight off infections. I don’t know if that conclusion has since been revised over the last 7 years.
