Just The Facts, Ma'am...
As everyone's goals are personal, I've done my best to research those facts which are important to me, and success with obtaining my goal.
a) Get the weight off, and start a full, active life, before I have suffer from co-morbidities or other unrelated issues.
b) Get the weight off before my daughter is cognisent my weight struggles. I want to be a role model for her, demonstrating the importance of living a healthy lifestyle. I DO NOT want her to think that her weight should be the all-consuming battle it has been for me for the past 20+ years.
Both surgies have associated risks, and I'd be happiest never experiencing them. However, I'd be remiss if I did not make them known.
