Is anyone else here doing the 5:2 Diet?

Hi

I've wanted to lose weight for a few years now and although I cant say I've ever really dieted before I did try to limit my food intake a few times in the past, but it only lasted a week or two at a time.

I discovered the 5:2 diet by accident and I've been going with it for just over two weeks now and combining it with majorly upping my excercise (bike riding, treadmill running) I've lost over 7lbs.
I eat approx 1200 calories for 5 days and then 600 calories on 2 other days that week. If I go over on any day by 100-200 calories I'm not too worried.
I've cut my alcohol intake enormously and almost entirely cut out my crisp (potato chips), buscuit and chocolate eating which is making a huge difference.
The great thing is that as much as I am on a diet, it doesnt feel like one because for 5 days a week I can eat, albeit sensibly and can have the odd treat if I want one.

Anybody on here doing this diet?
If 'Yes' what do you think to it?

    This IS the 5:2 diet. The calorie intake is suggested from their own website. Please dont tell me what diet I am on.

    Dr. Mosely's website? The guy is now hawking the "blood sugar diet" (he's moved onto other thing$).

    I read this book......the information I got was to "eat normally" the other 5 days. It said nothing about averaging an unhealthy 1,000 GROSS calories for the week, let alone dieting 7 days a week.

    I have been reading a lot about it and have been playing with limiting myself to 2 meals in a 6-hour time period, just to explore feeling hungry and to see how my energy levels do. So far, so good! I have read a lot of good things about IF, but have also read that women may not always see the same benefits as men (http://www.ncbi.nlm.nih.gov/pubmed/15833943?dopt=Abstract). Women also need to be cautious with it because of the risk of it becoming a chronic stressor -- a persistent level of stress will negate the benefits of fasting. (http://www.marksdailyapple.com/women-and-intermittent-fasting/) If it's a struggle, don't do it.

    It would be highly surprising if 1200 was your normal eating allowance / maintenance calories / TDEE that you are supposed to eat at on the 5 days - unless you are really, really tiny and sedentary?

    When you plug your numbers into the fastdiet website calorie counter what does it tell you?

    I am looking forward to hearing from people who are doing 5:2 and about their experiences with it, especially the "2" days.

    I have played around with 5:2, I had a friend lose about 15 lbs and is now maintaining at 6:1.

    I have to agree with the one person who called out that 1200/day plus the 2 low calorie days is pushing the envelope and probably not healthy for a sustained period. The point of 5:2 is that you don't have to "diet" every day, and unless you are very petite, you're dieting at 1200 calories

    I inputed my details, gave them what weight I wanted to lose and it gave me my 5 day calorie intake plus my 2 day 'Fasting' calorie intake.
    May I suggest you contact the website direct and inform them they are giving out the wrong information!

    What are your stats? I ask because you are basically eating 1028 calories per day with what looks to be quite a bit of exercise...

    Yep and where did the 1200 for a male come from, this calculator will not give this.. and no where does it ask you how much you want to loose?

    OP...You need to try again..

    But FYI, on 5:2 you SHOULD be eating mainenance on your non-fasting days.

    I went to this site, and this comes directly from the Get Started part:

    How many calories on a non-Fast Day?

    You may have wondered how we came up with the recommendation that women have 500 calories and men have 600 calories on a Fast Day. We used the rule of thumb that women need 2000 calories and men need 2400 calories per day and on a Fast Day you should eat a quarter of a normal day’s recommended calories. Some of you have also wondered exactly how many calories you should be eating on days when you’re not fasting.

    We thought we’d bring everything together in one place for you so you can do the calculations here. You can use the calculator on the right to calculate your BMI, BMR (basal metabolic rate) and TDEE (total daily energy expenditure). We’ll go into these in more depth below.


    I tried their calculator, and as a 52 year old, 5 ft 4 in, lightly active female, my TDEE is right at about 1900 calories. What are your stats?

    Are you looking at your BMR or TDEE on that site?
    You should eat TDEE.....

    Yikes I'm with every one else. I haven't done 5:2 but I have researched it pretty extensively and hang out on the IF boards sometimes. (I might give it a go eventually. Just have to get some things in order first, because consistentcy is really the key to any calorie deficit.) Please consider bumping your calories up. Use a TDEE calculator such as this one: http://scoobysworkshop.com/calorie-calculator/. Eat that 5 times a week and 500-600 calories on your 2 fast days. If it gives you 1200 because of your stats, then you've proved us all wrong.

    And if you feel you're eating "sensibly" at 1200 calories, just imagine what you could eat at maintenance calories. Might want to throw some crisps and chocolate back in. :)

    Mosely's 5:2 plan is this: two days a week of 600 calories and the other five days of maintenance.

    I believe the 5:2 strategy is 2 days a week fasting at the recommended calories and eating as you normally do on the other 5 days. Once you reach your desired weight you maintain by fasting only 1 day.

    I've been doing the 5:2 for about 3 weeks and am down 3 lbs. I am fairly active and do structured workout a minimum of 3 days a week. I chose to try this strategy because although I had lost 34 lbs I was sitting in a plateau for the last 5 months and wanted to change things up a bit. This appears to be working.

    I track my calories on my fasting days but not necessarily on my feed days only because the plan says 'eat normally' and whatever my 'normal' is is what it is.

    I do agree that eating 1200 on the feed days is not the intent of the 5:2 plan.

    No, it's not. I just went and looked at the website. It says exactly what Dnarules posted. There is no reason to get snippy and rude with us. We are just trying to help because eating at such an extreme deficit (without doctor supervision) is only setting yourself up for failure. If you want to try the diet fine, but try the actual diet. What you are quoting isn't it. We aren't trying to be mean here. Only trying to help. No need to be so defensive.

    Hate to hijack a thread but really don't want to start another one. I have been interested in trying 5:2 IF. I know it's 5 days at maintenance and 2 at 500-600 calories. I have done a bit research myself but one question remains... That is: assuming I use a sedentary TDEE estimate, what would I do about exercise calories? Could I eat a NET of 500 calories on fast days if I exercised? Could I eat exercise back just as normal on non fasting days too? Thanks in advance! I haven't seen anybody talking about whether it should be gross v. net calories in the MFP forums nor in any other forum I have looked up. :/

    On fast days, only 500 kcal. Regardless of excercise.
    The most correct TDEE is if you set a realistic amount of excercise. My TDEE is about 2000 kcal including excercise, so that is how much I should eat on non-fasting days.
    Then there is days with more or less excercise, but that has been taken into consideration when calculating the TDEE.
    Be aware of eating enough on non-fasting days :-)
    I dont do 5:2 at the moment, but has been on and off for over 2 years. It both does wonders for my digestion and keeps my belly flat, but it also stresses my body to much, so I can't sleep, I can't concentrate and I get too hungry and dizzy on fasting days, if I stick to the diet for too long a period. On fasting days I stick to tea and water until I have a normal meal with the family at dinner. I usually stick to the diet a month and the pause for a month.
    So please listen to your body for signs to quit.

    Don't understand why would you estimate a TDEE as sedentary unless you really are sedentary? Then it's moot point anyway! If you want to estimate TDEE then do it accurately.

    Could I eat a NET of 500 calories on fast days if I exercised
    No - it's 500 cals (for women, 600 for men) and that's it whether you exercise or not. Fasted exercise can take some time to get used to so build up slowly. I ended up being able to train just as hard fasted or fed but that took a lot of adjusting to.

    Could I eat exercise back just as normal on non fasting days too?
    Yes you can eat back exercise calories but only on the 5 normal days.

    Haven't seen anybody talking about whether it should be gross v. net calories in the MFP forums nor in any other forum I have looked up.
    Join the two 5:2 groups on here - the subject comes up a lot.
    Net calories is very much a myfitnesspal peculiarity but one I like as it suits my high but variable exercise routine.

    Don't confuse your self by mixing TDEE and MFP methods - do one or the other but don't mix and match.
    Don't put false information into either calculation (such as sedentary when you aren't!).
