Just back from seeing the GP re weightloss. I have lost 5kg in 3.5 months with a fairly strict diet of vegetables, protein, some low GI wholegrain carbs and no sugar, plus 2-3 per week gym sessions with other exercise on the other days (walk, videos etc). I was pretty disapointed in the weightloss as I'd been trying really really hard and I feel like I can't cut back my food intake to any less. I'm getting my hormones checked, thyroid is fine. Oh and I've got a long way to go on the weight loss front!

Anyway my GP "prescribed" 1 hour of hard exercise at least 5 days per week and no more than 1 day off between exercise sessions. Eeek! That sounds like a lot.

What do you reckon? Do you have a "magic number" for exercise for weight loss?
