I helped my dad lose 50 lbs by finally, after 10 years, getting him to give up bread, sugar, potatoes. It took buying him 2 months of Ozempic. Once he saw what stopping the cravings for certain foods can do, he believed me finally. At 65 years old, healthier than I remember since he was 40 and I was a teen. It doesn't require some weird bionic arm implant.
