Yes you are right BigM (I hope the M stands for Mike or Matt or something, I keep thinking of burgers when I read your name
This afternoon I went to the secondhand book store and purchased a great little book called Don't Diet!
by Rick Isaac and Eamon Murphy.
It's really an easy read and has pointed me in the direction of the snacks you speak of, it also recommends not consuming wheat, only oats if I want a grain food for breakfast.
It says it's only essential to exercise 3 hours per week (it can be broken up into 6 x 30 minute sessions throughout that week.
exercise, nutrition, strength training and flexibility are all essential as is drinking water (which I always tend to forget to do)
I'll read the book tonight to see what it's all about and start it first thing Monday.
