In my early 20s, I dropped pounds quickly by cutting out drinks with calories and walking more. In my late 20s, I moved to New York and walked A LOT. I ate and drank whatever I wanted and was thinner than any other time in my adult life.
Now I’m 40 and I have two kids. I have tried changing my diet and only eating certain things, but that didn’t work for me. I could come up with a sensible plan (don’t drink calories, have a fruit or vegetable with every meal, no snacks except fruits or vegetables, dessert once a week), but I couldn’t stick to it.
On the other hand, counting calories works for me. I use an iPhone app called LoseIt. You plug in your starting weight, height, age, sex, goal weight and rate at which you want to lose (for me, 1 pound a week). Every day, you track everything you eat and all exercise. You record your weight loss, and the app lowers your allotted amount of calories per day accordingly. My initial goal was to lose 20 pounds. I’ve lost about 15 pounds (my lowest was -18 pounds) and kept it off. I keep gaining and losing 3-5 pounds due to laziness (and ice cream), but I feel confident that if I want to lose more weight, I can just follow the plan more strictly and it will happen.
