Each time you eat, enzymes in your body's cells break down the food and turn it into energy that keeps your heart beating, your mind thinking and your legs churning during a grueling workout. The faster your metabolism runs, the more calories you burn. The more you burn, the easier it is to drop pounds. And get this—you can make your metabolism work harder, a lot harder, 24 hours a day.
This is known as metabolic adaptation, says Bustillo. When we drastically reduce our calories for an extended period of time, our bodies adapt to needing that smaller number of calories, which decreases our BMR. The longer this underfeeding happens, the further our BMR may drop. [CAN WE USE THE 'STARVATION MODE' ANALOGY HERE?

Whenever possible, slice each of your workouts into two smaller sessions. For example, do a 15-minute weight-lifting session in the morning, then do your 30-minute walk on your lunch hour or at night. You'll burn an extra 100 to 200 calories that day, explains Kelly Tracy, M.A., fitness coordinator at Duke University Diet and Fitness Center. Don't have time? Just add in some stair climbing or short walks throughout the day. Even small bursts of activity are enough to get your metabolism revved, according to a study in the scientific journal Nature. "I call it the mini stoke: For five minutes out of every hour, get up and do something, even if it's just walking around your office," says professor of medicine Peeke.

So, not only are you going to add on (or not be able to lose) weight because of alcohol, you also wind up looking older and sleeping worse. “[As you age] it will be increasingly difficult to get a good night’s rest with alcohol in your system and sleepless nights lead to carb and sugar cravings the next day,” says registered dietitian Martha McKittrick in 30 Foods You Should Never Eat After Age 30. Meanwhile, alcohol zaps moisture from your skin making fine lines more noticeable and speeding up your skin’s loss of elasticity.
So how many calories should you consume? Depending on your level of activity, you can safely lose anywhere from half a pound to two pounds a week if you multiply your current weight by 11, says Applegate. (For example, if you're 120 pounds, aim for around 1,320 calories a day.) Unless you're less than five feet tall, don't let your daily calories dip below 1,200. "Research shows that women who consume less than this amount see their resting metabolic rate plummet by as much as 45 percent," notes Dale Huff, R.D., a St. Louis nutritionist.

Choosy moms shouldn’t choose Jif—whether you’re spooning into the jar yourself or spreading it onto your kid’s PB&J. besides peanuts, the red-capped jar contains molasses, fully hydrogenated vegetable oils, and mono and diglycerides—which add more fat to the spread. Peanut butter can be a satiating, healthy spread if you choose the right one.

You might want to think twice before ditching dairy if you’re trying to lose weight—despite what your Paleo-preaching CrossFit friends tell you. Cheese is a satisfying, portable, and inexpensive food that’s packed with calcium, vitamin D, and protein. “Calcium can also promote weight loss because it helps maintain muscle mass, which boosts and helps maintain metabolism, helping you burn calories more efficiently throughout the day,” says Tanya Zuckerbrot, RD, author of The Miracle Carb Diet: Make Calories & Fat Disappear—With Fiber! That doesn’t mean you can help yourself to a cheese-drenched casserole, though. Work cheese into fiber-rich snacks to make them more satiating.
