LessFood, esp Sugars: Weight daily using scale with 0.1 lb resolution, 1st thing after arising & bathroom, nothing on, & log wt. Plot out goal date, subtract min. 1 wk & plot out dates back to current date to create schedule. Minimize food quantity, esp. Sugars & carbs, as needed; victoza (liraglutide) ± symlin (rx agents) an option to safely ?? apatite if needed. Stay physically active to keep muscle mass & BMR ?. All quite dooable.
