I wouldn't say I was particularly "overweight" though I am getting there, I weighed in early last week and discovered I was 13 stone 8lbs or 193lbs, standing at 6"2 that gives me a BMI of 24.8 so just 0.2 points of being overweight.
I discovered this "diet" after watching the Horizon program and decided to give it a go. I'm on week 1, fast day 2 and it's going well so far, I can definitely see myself sticking to this! I tried weight watchers for a while earlier in the year but it didn't really suit me, despite losing 4lbs on that, I put it back on quite quickly!
If I'm honest I'm primarily doing this for the health benefits, though weight loss comes a very close second.
