If you struggle to lose weight eating the same amount of calories that once allowed you to weigh a lot less, then it is a good indication your metabolism needs some work.
Chances are if you’ve been struggling with your weight for an extended period of time, more than likely you’ve screwed up your metabolism.
Yo-yo dieting—the process of losing weight and regaining it repeatedly—plagues many people who struggle to maintain a long-term fitness plan. There are many reasons why this happens: restricting calories too heavily, reintroducing calories too quickly, not building healthy habits that you can stick to, and going back to old eating behaviors once the weight is gone.
