Hello - I Have Been Trying To Lose Weight For

Hello - I have been trying to lose weight for the past year (and most of my life) but can't seem to get off this plateau. I live alone and do not have good eating habits. I crave sweets. Thank goodness I am not diabetic....yet. I had bilateral knee surgery just a year ago and am still trying to heal from that surgery. Is there something
That would curb my craving for sweets? Thank you.
