Yes, eating less and exercising more is one simple, tried-and-true weight loss strategy.  But here are three weight loss secrets you might not have heard of.

Secret number one: Turn down your thermostat a smidge. Studies indicate that cozy indoor temps may inhibit calorie-burning because your body will burn extra calories to keep warm. But not if it's feeling toasty. Research suggests that keeping temps below 68 degrees Fahrenheit may help fire up your metabolism.

Secret number two: Go to bed early. A lack of sleep throws your appetite hormones into the “gimme-more” mode. Poor sleep also affects blood sugar and insulin levels in a way that can increase the risk of excessive weight gain. Your goal: 7 to 8 hours of nightly shut-eye, day in and day out. 

Secret number three: Cut down your dining out to once a month. In the study, eating just one restaurant meal per week upped the risk of obesity by 50%. Preparing meals at home allows you to control fat, sugar, and salt content - and lets you know exactly what you're eating.
