Q: I’ve gotten my food habits pretty well under control, but I’m still gaining weight! What could be causing that? -- Kayla E., Tucson, Arizona A: That is a great question -- because so many people find out that their weight issues develop from a combination of problems, not just overeating or eating the wrong foods. You know, of course, that for long-term weight management, you need to crank up your metabolism and build more calorie-burning muscles by getting plenty of physical activity (300 minutes a week minimum). Plus, muscle and metabolism decrease by 5% per decade, so you need to eat less to keep weight constant. But other contributing issues could include: 1. Lack of restful sleep. Too little sleep increases secretion of the “feed me” hormone ghrelin and suppresses the “I’m full” hormone leptin. It’s also linked to elevated levels of the stress hormone cortisol and a growth hormone deficiency -- both can contribute to obesity.
