I'll be happy to help. I agree that it's important to stay lean and in the best of health. Your body is still adjusting to the change in eating, so try to be patient and five it a little time. Your comment that you feel as though you've lost weight shows you are entering the Zone. The extra pound could very well be due to a variation in hydration levels from the last time you weighed (wt can change by several pounds either way due to level of hydration). Be sure to drink plenty of water to prevent fluid retention. The current Zone recommendation is to drink a 16 oz glass of water before every meal. Carbohydrate choices are of the utmost importance. Judge your success for now by mental clarity plus lack of hunger 4 hours after a meal. If you have hunger at 4 hours use the hormonal adjustment chart to adjust carbohydrate amounts (http://drsears.com/portals/6/Docume...lchart.pdf
Rather than the scale, use the Body Fat Calculator on this site to monitor your fat loss (http://www.zonediet.com/tools/body-...lculator).
Dr. Sears recommends to use your calculator stats form 2 weeks after beginning the Zone so give it another week to calculate your baseline. During the first two weeks of the diet you can still be retained fluid, and that will skew your calculator result. The goal will be for your body fat to decrease (if you are still above 22% body fat), and for your LBM to remain stable or to increase.
Since you have a hypothyroid concern (assuming that's why you're taking Synthroid), you might need to practice stricter adherence to Zone principles. I have a lot of experience with hypothyroidism and the Zone. I have hypothyroidism as do several relatives of mine who all follow the Zone diet. We've all been very successful in losing the excess weight and keeping it off for good. A tip, a small number of carbohydrates have changed category from favorable to unfavorable since "A Week In The Zone " was written,. Defer to the most up to date Food Block Guide (http://drsears.com/ArticlePreview/t...ult.aspx).
If you have any questions or would like me to take a look at your meals to suggest whe to fine tune for you needs feel free to post the information here.
Have a nice weekend!
