The way many of us think about weight loss is totally counter-productive. Focus on healthy habits you can sustain instead of the numbers on the scale. Here's what to remember: - Forget goal weights. Instead, focus on behavioral goals. - Start with small changes and let them snowball. - A loss of only 3% of your body weight can meaningfully improve your health. - Remember that your best weight is the one you reach when you live the healthiest life you can actually enjoy.
