One Diet does not rule them all!

I completely understand that one diet does not fill all, but, people that are diagnosed Hypothyroid, which diet have you found works for you?

I was going to try Keto, but having read up, it can be a something that causes diabetes. So then I though, why not try a Diabetes diet? I read this can cause other problems. But, would I not find this with all diets?

I calorie counted for 8+ weeks and found that even without following any sort of real plan, I was well within, sometimes under my daily count. My foods are varied and I cook 90% from scratch myself as I am home all day.

Only 'help' from a Dr is a 12 week voucher for Slimming World, which is pointless because I can not afford to buy the foods they want you to eat!

Please help this chubby Hippo to lose some weight... I am too big too even walk more than a distance of 10ft without being in pain and out of breath, yet my calories intake is perfect!
