Why that’s so important: “The more muscle we have, the more calories we burn,” Kirkpatrick says. Even if it doesn't actually help you lose weight, it can help keep you from gaining it—along with all the other good things it does for your body, mind, and life. Lots of over-40 guys like HIIT, since its compressed timeframe ends up having a low impact on your schedule.
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.
Yeah, you've probs heard that diet tip before—as it's wise for anyone trying to lose weight. Fried foods contain a whole lot of fat and contribute to weight gain—simple as that. But again, in your 40s, you deal with natural physiological changes that make it *even* tougher to shed excess weight, so overdoing it on fried foods has larger consequences. "A 20 year old can get away with eating empty calorie meals. A 40 year old usually cannot on a semi regular basis," Mirkin points out. "Until we are age 20, [our] bodies are building muscle. After age 20, it stops."
If you eat healthy and exercise regularly and still can’t lose weight, your thyroid might not be working like it should. This happens in about 5% of people, and it's most common in women and people over 60. In addition to weight gain, it can also cause fatigue, joint or muscle pain, and depression. Medications can help, so get it checked if you think it might be an issue.
