Hi! I'm gad your doctor figured out some of your issues! Many dr's don't. And i hope you are on your way to feeling much better!
1. Wait 1 hour after taking your pill before you eat. Food will cause you to not absorb the medicine. Especially milk products and especially man made thyroid such as synthroid/levothyroxine.
2. Stay away from soy. It's a thyroid killer. Slows it down (and your metabolism).
3. Stay away from goitergenic foods such as broccoli and cauliflower. However if you cook it really well it removes a lot of those properties that slow your thyroid down.
4. Do you have the autoimmune version? If so know that it can tend to bounce around. After a time on these pills you will get to know if you're not on enough or too little. Go by how YOU feel... not the numbers.
5. I found taking thyroid did NOT make me lose weight, though you most certainly are a whole different human being and could
I gained 100 pounds in about 6 months. What the thyroid pill did was STOP me from gaining. (Thank the lord)
6. Easy on the flouride. Flouride is the medicine the use to stop HYPERthyroidism (ie kills your thyroid in a small dose). So don't eat your toothpaste and easy on the tea! Natural tea leaf plants absorb the most toxic flouride from the grounds and it can affect your thyroid.
It's really about you. There really isn't a thyroid diet though a lot tend towards low carb. You need to do what is best for YOU and what will fit into your own schedule. I do low carb, low sugar (from whole food only), low cal, low chemical/processed. I never lost weight until I got on Metformin (for insulin resistance).
It is definately tougher to lose weight being hypothyroid. I recommend Mary Shoman's website. Se has a weight loss section. As long as you are striving towards healthy foods and not pointless foods, I think that is the most important.
