I've lost 2 pant sizes. Does that count?
My take-- first and foremost focus needs to be put on getting adequately/optimally treated for thyroid issues. For me, that means getting free T4 and free T3 to at least midrange of their respective ranges.
After that, I believe your body needs time to heal. That time depends on how long you were hypo and untreated or undertreated. Trying to force the body, through strenuous dietary and/or exercise changes only exacerbates the problem.
Once your body has had time to heal then you can implement diet and exercise protocols that will, as a primary function, promote health and as a perk will bring about weight loss.
My journey-- I most likely went undiagnosed for years. During that time I ate less and less while exercising more and more. After diagnosis I was kept under medicated due to low TSH, yet got got sicker and sicker.
About 7 years later I finally convinced yet another new doctor to ignore TSH and increase my meds. That small (12.5 mcg) was all that was needed for me to see a steady improvement in wellbeing. It took about another year before I felt well enough to implement diet and exercise changes.
Today, about 11 years after diagnosis and 2+ years after diet and exercise changes I am healthy and at a healthy weight.In the end, what worked for me was taking the focus off weight and putting it on making healthy choices on a daily basis.
My husband also is hypo, and I totally agree with all of the above. His doctor refused to give him Armour (dessicated thyroid) and wanted to give him Synthroid (synthetic thyroid). We finally figured out that we could order dessicated thyroid online for ourselves, and the doctor is completely unaware that he's not filling his prescriptions. Says his blood work is perfect, lol.
A really good resource for learning to manage your illness is Stop the Thyroid Madness, which I was lucky enough to find when DH was first diagnosed. That's how I found out about the dessicated thyroid's superiority to the synthetic, and so forth. Especially click on the T-4 Only link and follow the T4-Only Meds Do Not Work link, if you're unsure about the dessicated thyroid. And we buy DH's Armour on http://www.overseas-foreign-pharmacy.com/product_category.php?cat=37, if you're interested but can't get your doctor to prescribe anything but Synthroid. I'm sorry to sound like I'm pushing this, but my SIL had a really horrible experience with Synthroid. It caused her to lose all her hair; she was bald as a cue ball, and the hair would not grow back while she was on the medication. Do a search on Synthroid + Hair Loss, there are a zillion links out there.
As marcadav said, don't worry about your weight right now. Worry about healing yourself, getting your hypothyroidism properly treated. As your body heals with the right combination of meds, diet and exercise, your weight will take care of itself.
Your book club may have scintillating discussions. But my book club can drink your book club under the table.
Remove all fluoride, chlorine from your life that you can (toothpaste, teas, city water for drinking/shower/bath). The thyroid needs iodine. Fluoride, chlorine, bromide/bromine compete with iodine for absorption. Read everything you can find about iodine supplementation. Find a doctor willing to work with you on natural methods.
For about 90 percent of people hypothyroidism is caused by Hashimoto's, an autoimmune disease. Until this is addressed you may struggle with weight and other symptoms despite doing everything right or even being on medication. The book that best sums it up is "Why Do I Still Have Thyroid Symptoms When My Lab Tests Are Normal?" by Datis Kharrazian.
Going grain-free is great for many autoimmune conditions, but you may also need to investigate whether eggs, dairy, or nuts are a problem for you. Many people with chronic autoimmune issue also have chronic leaky gut issues and develop many food intolerances. Eating foods that trigger inflammation will perpetuate the problem and the symptoms.
There's lots more to it of course, but understanding that you're most likely dealing with an immune issue is often a good place to start.
