hi,
firstly, since you have high level of cholesterol , the reduction in cholesterol level can not be controlled only by your diet and physical activity and hence it is really essential for you to take tablets.
secondly, no relation with the weight reduction and your cataract surgery. however after surgery for sometime not advisable to physical activity.
about your concern over the non-reduction of cholesterol even when you are on diet, that genetics has role in cholesterol regulation. and there are other multiple factor like physical activity etc, so please dont be demotivated by that.

wish you good luck in weight reduction and cholesterol reduction.

DEAR SIR/MADAM

ITS MUCH TO WORRY ABOUT LDL - C CHOLESTEROL AND TRIGLYCERIDES LEVELS RATHER THAN TOTAL CHOLESTEROL
SEE WHAT IS YOUR HDL - C STATUS.

IF YOU HAVE THESE LEVELS ELEVATED, ITS BETTER TO START MEDICINES, EVEN TAKING STATINS WILL HELP TO CONTROL PROGRESSION OF RETINOPATHY, SO GO AHEAD TAKING STATINS.

ATORVASTATIN IS BEST, ALL THE BEST

THANKS

Thanks for your question

Reducing Cholesterol without Drugs:
Avoid oily food
Avoid fast food and bar be que
Avoid Beef

Cholesterol and Diabetes: well cholesterol does not cause diabetes, rather in diabetes there is a risk of deranged cholesterol levels and you need to decrease it to a certain level in diabetes.
