Hi all, I have been doing the 5:2 way for approx 9 weeks and lost 16 lbs so far. I have worked out my TDEE via the calculater and it comes in under 1500, which isn’ta problem for me. On fast days I eat between 440-480 cals. On some 5:2 pages I have seen people getting put down because they get told like me, that for the ‘science’ to work you have to eat over 1500. But surely as your weight decrease’s so does your tdee? I have inputed my details like height( 5ft 3) age etc correctly … I would appreciate positive feedback…many thanks 🙂

Everyone’s TDEE varies, so if yours has calculated out to 1500, that’s totally fine. And you are absolutely correct that as your weight decreases your TDEE decreases. It also will decrease as you age, and if you become less active. You are doing it right by following your TDEE, not some arbitrary 1500 number.

Congrats on your 16lbs lost, sounds like the science is working just fine for you!

I don’t know about other 5:2 pages, but here we don’t really put people down. That’s why this is the only 5:2 page I bother with. 🙂

I have a question here – starting my day one of fast tomorrow (actually it’s started at 8pm today) – will it be a problem if i don’t eat as much as my TDEE-it’s at 1975 calories now. I dont think I consume more than 1500-1600 on a daily basis – so is it okay if i stick to that, or will that prevent a weight loss?

Hi and welcome:

The basic rule is the less you eat, the more you lose.

There is no problem with eating less than your TDEE. Some discourage it because you might be more hungry and have more trouble sticking with the program, but from a scientific/weight loss point of view, if you want you can eat less than TDEE on non-diet days and less than 5/600 on your diet days. Here is a bit more information on TDEE: http://thefastdiet.co.uk/forums/topic/tdee-for-the-curious-or-why-dont-i-lose-weight-faster/

Good Luck!

I think the biggest problem with eating up to your TDEE is not logging food properly and going over it!

It is very easy to underestimate calorie intake, by underestimating portion sizes, forgetting to log harmless looking things such as cookies…not logging sauces and not weighing your food.

I log all of my food on myfitnesspal and if in doubt I weigh it. I also calculated my TDEE with activity set to sedentary, eventhough I work out nearly every day.

Nothing bad should happen to you if you eat under your TDEE as long as you stay over your BMR.

Best of luck
Stef.

Thanks all for your replies, it’s reassuring to know that I am doing it ‘right’…on normal days I don’t go hungry and I do log my intake into MFP, but sometimes struggle on fast days so I don’t 1/4 my tdee as it would be so little…on some pages the information given out is so misleading in so much as newbies keep posting the same questions and get varying answers..confused.com… thanks again 🙂

1/4 of my tdee would be fairly small too, so I just eat 500 cal on fast days, and up to my tdee on nonfast days. So far I’ve been losing (10 weeks now) so I think you should be fine with what you’re doing.

@stef. Thanks for the response. It’s a good insight. Today’s my first fast day and I have even weighed in a tomato I ate with my breakfast oats 🙂 But on a non-fast day, how is it that people are saying ‘all you can eat’ carbs/desserts and everything else?
I’ve been eating healthy and watching my portion sizes, so don’t intend to change that because I am on this diet – so i should be able to stay under my TDEE 🙂

Hi again Brown:

People might be saying that, but if they do it they don’t lose much weight.

5:2 works on calories, not on types of foods eaten. So you can eat cake and drink soda every day – if you keep within your caloric limits of 500 or less on diet days and TDEE or less on non-diet days.

There is an ongoing discussion on what ‘eating healthy’ means. Science has shown recently that diets high in fat and low in carbs are more healthy than the previously touted ‘low fat diet’. However, from a 5:2 point of view, it is the calories that count, not the food eaten.

Good Luck!
