I started out on 5:2 and lost 5kg over about 8 weeks which was fantastic. I started reading all the posts about 16:8 and thought that given that I only had 3-4 kg to lose I would give it a try. I had expected that I would maintain my weight and not lose any but what has actually happened is that I have continued to slowly lose weight on 16:8 alone.
I have stuck to 16:8 everyday and haven't found it hard at all. Eating normal lunch, having afternoon snack and normal dinner at night. My only rules have been to cut out wine during the week and drink only at weekends which has helped with my sleep patterns and I have reduced the amount of sugar I was consuming.
All in all I feel great, i have lots of energy and I'm not stressing about food because nothing is restricted, I can have a slice of cake or a sweet treat occasionally. Very pleased with the results.
Keep you posted on whether the weight stays off.
