I was 347lbs at the time. Wasnt a diabetic (nor pre-diabetic) no heart disease, blood pressure or really anything other than my weight. Prior to then Id had two massive bouts of weight loss at 50-100lbs so I know what it takes. Id tried but this last time without meds was extremely hard. You cant do much in the way of productive exercise when both your shoulders need replacement at 30 and between two knees have an ACL tear and two MCL tears. To top it off I had wildly out of whack hormones.
