What's your view on intermittent fasting?

I've been trying to stick to this:

2 weetabix with semi skimmed at midday or 1

At 3 or 4 have some chopped spring onions, peppers, cheese, ham, grated carrots, brown pasta, salad cream & spicy coleslaw

At 6 or 7 have rice & spring onions, peppers, ham or chicken

Then that's it for about 18 hours

Of course, I have on odd cheat meal.

The purpose is to lose another 2 stone. I'm 12st now & was 14.

I haven't done my boxing training in a few months so I'm not sure there's any point in fasting if I'm not working out?
