I have found keto to be the only way to loose weight with 18 hour fast each day.

If you take medication for your hypothyroid you may want to talk to your doctor to see if your dose needs to be adjusted. I have the same thing. My doctor put me on a medication for weight control. I find that walking helps a lot. Also drinking a lot of water dose help. Try a low carb diet.

Weight control medicine which one is that?

-20-30 active minutes per day -Increase thyroid medicine if necessary- talk to your doctor about a goal range (mine is tsh under 2.5) -increase water intake - I stay away from “fad” diets, gluten is a known inflammatory / trigger for some thyroid issues. I cut/ keep gluten at a bare minimum -I am working with functional medicine dietician to figure out what’s best for me which will be different for others

I agree with you. Reducing carbs, sugar, dairy, and packaged foods has helped me.
