But a simple plan isn't always an easy plan. Changing your daily movement habits can be hard. So I've developed this 3-step plan to increase your metabolism while you keep your food intake the same. You'll create the energy deficit needed for weight loss without an expensive diet or hard-to-find foods. Follow the program for 2-3 weeks to increase your energy levels, boost your metabolism and put your weight loss program into hyperdrive.
The more often you eat, the faster your metabolism will be. However, eating more often does not mean you can consume heavy foods with high calorie intakes in greater frequency. Instead, your calorie intake is divided into three meals a day with two healthy snacks in between your meals. Dr. Oz recommends dieters to eat within an hour of waking up to inhibit the body from going into starvation mode. To keep your metabolism up and running, he suggests to adhere to the schedule below:
To get why, you have to understand a bit of the science behind metabolism. Your metabolic rate is essentially the speed at which your body expends energy, and it depends on many different factors. Your age, weight, health history, organ function, oxygen capacity, and even your height can all influence how many calories you burn during exercise, but also (and more importantly) during sedentary times of day.
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.
Most of us choose one time of day to get our exercise in—whether that’s first thing in the morning or right after work. Though having a routine is helpful, Katherine suggests incorporating physical activity into both morning and night. For example, if you typically only exercise in the morning, then do a little something in the afternoon or early evening to bring the heart rate back up for a bit. “Evening exercisers can do the same thing in the morning,” she says. “Ten to 15 minutes of some activity in the morning will jump-start your metabolism for the day and will do a world of good.”
It’s no secret that experts recommend putting away blue-light devices, such as smartphones, tablets, and laptops, at least an hour before bed to improve sleep quality. However, a recent pilot study from Northwestern University shows that exposure to blue-light at night can impact glucose metabolism. Although the exact correlation is still being studied, John La Puma, MD, suggests ceasing exposure to blue light two hours prior to hitting the sack. “It resets melatonin levels so that getting to sleep becomes harder, and too little sleep means weight gain for most people,” says Dr. La Puma.
What should you be having? Morning munchies that are slow to digest and leave you feeling fuller longer. Try a mix of lean protein with complex carbohydrates and healthy fats, like this power breakfast, recommended by Berardi: an omelet made from one egg and two egg whites and a half cup of mixed peppers and onions, plus a half cup of cooked steel-cut oats mixed with a quarter cup of frozen berries and a teaspoon of omega-3-loaded fish oil.
Research shows that getting plenty of protein can boost your metabolism, causing you to burn an extra 150 to 200 calories a day, says Jeff Hampl, Ph.D., R.D., a spokesman for the American Dietetic Association. "Protein is made up mainly of amino acids, which are harder for your body to break down [than fat and carbs], so you burn more calories getting rid of them," he explains.
Experts say weight training is the best way to crank up your resting metabolic rate. "As you get older, your resting metabolic rate drops, but weight training can rev it right back up again: A pound of muscle burns up to nine times the calories a pound of fat does," explains fitness expert Westcott. In fact, a woman who weighs 130 pounds and is muscular burns more calories than a sedentary 120-pound woman of the same height. Regular strength training can increase your resting metabolic rate anywhere from 6.8 to 7.8 percent. (That means that if you weigh 120 pounds, you could burn around 100 more calories a day, even when you're just watching TV.)
Spreading your meals throughout the day might keep you from getting too hungry and overeating. If so, it is a good idea. Athletes perform better when they eat more often in smaller amounts. If you are someone who has a hard time stopping once you start eating, 3 meals a day may make it easier for you to stick to an appropriate intake than lots of little snacks.
Noshing throughout the day is a proven strategy to help you curb hunger and eat fewer calories overall. Now, experts are promoting nibbling versus gorging as a way to keep metabolism running by holding blood sugar levels steady and preventing weight-gain-promoting insulin spikes. Enjoying six small meals a day should do the trick; keep them around 300 calories each, or divide your usual day's calories by six.
Stop obsessing over numbers. Quality over quantity becomes key for optimizing mitochondria. That said, if you’d like to know how much you should be eating, calculate your resting metabolic rate (RMR) or the total number of calories your body needs to survive at complete rest. If you eat fewer calories than your RMR, your body thinks it is starving. Calculating your RMR is easy. If you are average size, take your weight in pounds and multiply by 10. If you are very muscular and lean, multiply your weight by 13. If you are very overweight, multiply it by 8. Eating less than your RMR means your body goes into starvation mode.
