To jumpstart your weight loss, the biggest focus should be to develop habits that will help you build or maintain your muscle mass. "The most effective way that women over 40 can boost their metabolism is by building muscle through weight-lifting and resistance training," says Dr. Peterson (more on that to come). But nutrition and sleep habits also play a role here.
When you’re busy with work, kids, and life, you can be tempted to grab food on-the-go or multitask through a meal. But you’re more likely to overeat -- and be hungry again soon after -- if you don’t focus on your food. Sit down for meals and tune in to what’s on your plate (not what’s on your TV or computer screen). That helps your brain realize when you’ve had enough.
