.... My weight has been fluctuating between 210-220 lbs (95.5-100Kg)....
something about this sounds so familiar....
i have two knee replacements.
i have one hip replacement.
i'm 5' 11".
i'm 66 now.
i started making an effort to lose weight when i hit the mid 220's.
for about 3-4 years i was stuck between 210 - 217 lbs.
i then made two changes...
i drastically cut the amount of sugar in my diet.
i started intermittent fasting.
over the first 4 months i dropped ~10 lbs/ month.
over the following year i've dropped another 10-15 lbs.
my original goal was to get back to ~190 lbs.
i'm currently in the low 160's.
i've got a pretty arthritic shoulder, so i have given up on most gym exercising in favor of now, simply walking.
aside from my shoulder, the weight loss has nearly eliminated any other joint pain. i haven't had to take an anti-inflamatory med in well over a year. kneeling on replacement knees is never a pleasant experience, you're not alone there. and my A1C is well below 6 now.
just something to think about.
good luck.
