I need to lose about 20 pounds (at least). I've been overweight my whole life but only started doing something about it when I was 14 (I'm now 21). It seems I constantly go through the cycle of losing 15-20 pounds in 6 months or so and then within a year I gain most or all of it back. I'm almost back at my starting weight when I was 14, which for me is the heaviest I've ever been. I eat fairly healthy meals, but my weakness is totally dessert. And I really need to start exercising on a regular basis but it's just so hard for me to get started. Once I get to the gym I work really hard, but the hardest part is getting there.
How do you find motivation to stay away from temptation (i.e. desserts & sugar)? How do you motivate yourself to create a workout routine and stick to it?
