I cant do the 5.2- I managed it for 16 weeks and lost 17lbs but I dont know what is wrong with my mindset- I just cannot get back into it- regardless of how much I am convincing myself that for me, it works.
Ive seen some references to '16:8'. I think I have grasped that the concept is to eat for just 8 hours out of the 24. How many calories though? and how many days a week do you do this? also- most importantly--- Does it work??
Yes, 16:8 means eat within an 8-hour window and fast for 16 consecutive hours. Almost everyone who loses weight needs a calorie deficit ( the exceptions are those for whom fasting clears up a metabolic problem or removes a trigger food)
Easiest method is just to cut out either breakfast or supper and do NOT eat bigger meals in those 8 hours to compensate.
For best results, do this every day After 2 weeks, see if you have lost weight and tune your intake if need be.
If you find that you need to count calories: To achieve a 3,000 cal weekly calorie deficit and hence about 1lb loss, you need to average about TDEE-430 cals per day
btw, once you get used to fasting on 16:8, you might find you can add FDs again. Many of us on 5:2 do 16:8 on NFDs.
