Zone Dieter Considering CR Lifestyle

[Guest guest]

Hi:

I've been following a 40-30-30 diet for a long time (>12 years) and

it's worked well for me in terms of controlling insulin levels, giving

me more energy, less soft tissue issues, etc. (I've always been skinny

and never really had a weight problem.)

As I get older, I'm considering the advantages of a more calorie

restricted diet. I eat pretty " lightly " now, but justify eating an

entire bag of chips or equivalent a few times a week by thinking that

binging is somehow " natural " (in an " ancestral diet " sort of way).

So, I'm just wondering if there is any advice for switching from zone

type diet to Calorie Restriction. I can imagine it being a matter of

reducing portions even a bit more and maybe having to give up intense

exercise to avoid need for large amounts of carbs (with the thinking

that with moderate exercise, you use can use predominately fat as fuel).

Any thoughts appreciated,

Jon
