As long as you don't go nuts on nuts (which can be calorie overload), they can be super beneficial in helping you lose weight. In a study published in the European Journal of Nutrition, researchers found that those who got their protein from nuts instead of animal products had less weight gain than those who never ate them. So consider this your permission to snack on peanuts, almonds, hazelnuts, pistachios, and walnuts — so long as you practice portion control. If sodium is a concern, grab roasted or raw over salted varieties.

Napping may be an easy way to catch up on some missed shut-eye, but dozing off in the middle of the day does nothing to aid weight loss. In fact, research has found that people burn fewer calories when they sleep during the day and log their waking hours after the sun’s gone down. To come to this finding, researchers at the University of Colorado at Boulder studied 14 healthy adults for six days. For two days, study participants slept at night and stayed awake during the day, then they reversed their routines to mimic the schedules of night owls. When participants slept during the day, researchers found that they burned 52 to 59 fewer calories than they did while catching their Zzzs in the evening—likely because the schedule messed with their circadian rhythm, the body’s internal clock that plays a major role in metabolism function. If your circadian rhythm is out of whack, a separate study by University of Colorado Boulder researchers suggested spending a weekend in the wilderness to get it back on track.

One thing restaurants (and individuals) typically overdo it on when cooking is salt, and that can easily cause unhealthy bloating and weight gain. In fact, one British study found that for every additional 1,000 milligrams of sodium you eat a day, your risk of obesity spikes by 25 percent, so ditch the salt and stick to metabolism-boosting spices such as cayenne and mustard instead.
