Do you stick to a certain number of calories on your 5 non fast days? if so what have your weekly/monthly losses been like? I am tempted to try the 5:2 plan but a part of me thinks I wont lose on it, I'm willing to give it a try but first I would really like to know what peoples calorie intake is on their 5 non fast days. I have been doing a lot of searching and so far all I have found is for females to eat no more than 500 calories on their 2 fast days but I just cannot find a calorie limit for the non fast days. All I have found is to eat normally, but then I find myself asking "what's normal?" I'm not sure I really know?... if I did maybe I wouldn't have gained nearly 6 stone. One of the things I like about JUDDD is the calculator, knowing what my allowances. Even with me knowing my limit I find myself still going over so I don't think being told to eat 'normal' will work for me. I found another forum dedicated to the 5:2 plan and they mention on there finding your TDEE (total daily energy expenditure). Once you have that, to get a loss of 1 lb per week eat 3500 less blah blah. So what I did, which I could have done it totally wrong! is: my TDEE is 1906, so I multiplied that by 7 then subtracted 3500 and subtracted another 1000 (for my 2 fast days) to leave me with my calories to eat over my 5 non fast days. It leaves me with about 1768 for my 5 non fast days. For 1.5 lb it would be 1418 for my 5 non fast days. Maybe I have done that wrong though. Looking at those figures I could see me doing the 1768 on my 5 non fast days but I don't think I would do so great on 1400 calories a day on my 5 days - I think I might end up feeling like I'm on a low calorie diet - me and diets where I start to feel deprived do not mix, that's why I like JUDDD so much - I just can't help but be tempted to try 5:2.
