Hi to all, Just joined this site. I have had hypothyroidism for 25 years. Now on 75g. This has varied over the years between 50 - 150g. If anyone can explain these results I would be grateful. The blood was not taken on an empty stomach, and I had taken my dose 2 hours before! Now I know different! The Serum TSH level is 2.27, is this okay? Or should I aim for it to be higher, or lower? I have good health, but always struggle to lose weight. Now on a diet of 800 calories a day (Michael Mosley, not for diabetes, just to lose about 10 lbs I would like to shed). A few years ago I lost a lot of weight on SlimmingWorld, but now find it hard to shift; and for their regime to work for me. Wondered if my dose is too low to move weight? I am finding I can lose weight on 800, about 1-2 pounds a week - which does not seem like much!! Thanking you in anticipation for any comments or advice.
