I've lost a total of 50 pounds, still have 40 more to go. Did Weight Watchers but it's just too expensive right now. However, I have learned how to make a lifestyle change from Weight Watchers so I'm just continuing to do those things.
Make sure to eat 5 servings of fruits and vegetables every day, 2 dairy, 2 tsp of healthy oil (choose from sunflower, oil, safflower, canola -- there's 2 more but I can't remember them), 6 glasses of water.
Weight loss is all about increasing your activity and making better food choices. Choose low or no fat whenever possible, trim visible fat from your meat. Choose less processed foods whenever possible (brown rice vs white).
Good luck and remember -- weight loss is a marathon, not a sprint. It didn't come on quickly, it won't come off quickly. Healthy weight loss is 1-2 pounds per week.
