After a year of lower dose Thyroxine, reduced from 200 micrograms to 175, I notice that I am losing again.
I know that I must have gained at first, just from my waist measurement, but the low carb regime is having an effect again.
It is not so much a diet as a way of eating, and the only one which controls my weight.
On 'normal' diets with lots of 'healthy' carbohydrate I put on weight uncontrollably, exercise will not stop the gain and reducing diets counting calories are no help as I go into hibernation.

I had lost 14 inches off my waist, and am back to 2 or 3 inches of that now.
I carry all my weight around my middle as a 'bay window' effect, so when I say my waist sucks - it really does.
