Is 4 hours of working out a week enough to lose weight?

If you burn more calories than you eat, you will lose weight. Keeping a food and activity log has helped many people find the right formula for their personal weight-loss plan. It's hard to say whether or not 4 hours per week will be right for your goals, but if you keep track of your progress, you'll know in about 3 weeks or less. Personally, I think that dedicating 4 hours a week to fitness is a solid and sustainable plan.

Also, keep in mind that if you are already lean or at a healthy weight, the rate of weight lossmay be slower than if you are overweight. I'm about 115 pounds, but I use to be 134. My weight loss was at the rate of about 1-1.5 pounds per week.
