@chasey – 10 days ago my weight was below 78kg. On Friday morning it was a little over 83kg and today it was 79.3kg. That was mostly water weight coming and going. Weight is really a range and you mostly likely just saw a high point.

You can use other measurements if you like. How do your clothes fix for example. One can even use a cloth tape and make measurements.

On the average a lot of people lose about 1lb per week on 5:2. I lose less than that because my body fat is getting low and I workout harder to build some muscle. I also eat above the recommended amount on non-fasting days.

There is a large number of variables:
* How much you are eating
* What types of foods you are eating
* When you are eating and how often
* How much weight you have to lose
* How you exercise
* etc
