Yea I dropped about 100lbs. Not exactly sure cause I never weighed myself at my heaviest. I was living abroad at the time and started keto and from then on the weight just melted off.
I wasn't even doing anything - just eating keto to satiety every day. Then I moved back to the US and slowly began gaining it all back (also over about 2 years).
I tried various things to slow down or reverse the gain, including lifting, other methods of working out, dieting more or harder.. nothing worked. Until this :) With the heavy cream. Down 45lbs again so far. Yay!
Having done that for two years, why was it unsustainable to eat at maintenance from then on? You felt hungry? Lost interest? I lose interest in goals all of the time. But what happened?
