I eat 500-600 cal. usually every Monday and Thursday. Lunch and dinner.
As I had not experienced any serious weight loss aroung May, I started fasting 15-16 hours a day (non-fasting days), meaning that I only eat for about 8 hours a day. This really helped me to start losing weight. During my summer vacation in July I didn't always do the 15-16 hour-a-day fasting, but I started on that again in August.
Now for a month and a half I have been actually gaining weight despite I am on the 5:2 PLUS only eating for 8-9 hours a day on non-fasting days. I think I am doing all I can, but it is still not working.
You can see my progress in the graph below. It might be easier to see here: http://oi61.tinypic.com/2s0oc51.jpg
On fasting days I usually eat soups, salads, whole wheat bread/pasta, brown rice etc. I try to avoid empty calories.
On regular days I eat typical meals, not particularly healthy or unhealthy foods. It varies. But I do eat a lot of chocolate and sweets, but that is how manage to survive the fasting periods.
Does anyone have suggestions for what I can do? It is becoming difficult to keep doing this when I am actually gaining weight.
