If you’ve struggled to lose weight in the past, or if you’ve lost weight and then gained it back, it’s important to remember that what you’ve done before just doesn’t work – if it did, you'd be at the weight you want. Being very restrictive DOES work for fast weight loss, but it DOES NOT work for weight maintenance. If you want this time to be different, you have to do things differently, even if it means you lose weight more slowly.
