I have been in the zone for about two weeks now and have started feeling dizzy and lightheaded. The same thing happened to me a few years ago when I tried the zone and it took me over a month to feel normal again.

I really don't want to go off the diet and was wondering if anyone else experienced this and if you can offer any advice.

Hi Lynn Ellen!

Recheck your personal block requirement and the composition of your meals. It sounds like either you're not eating enough, or you're eating too many carbs in relation to protein, or both. If you're taking fish oil make sure you're at an appropriate dosage, and not taking too much. If you'd like to post your typical day of meals and snacks I'll be happy to take a look.
