Use a calorie-needs calculator like LIVESTRONG.COM’s MyPlate app to figure out your daily calorie needs, then subtract calories to create your energy deficit. With an app like MyPlate, you can factor in your weight-loss goal, and it will tell you the exact number of calories (as well has how much fat, protein and carbohydrates) you need to reach that goal.

And maybe a new mattress, because it’s not just the amount of time you spend sleeping that keeps you lean, it’s also the quality of your sleep. Fat cells in your body produce a hormone called leptin that helps the body keep track of how much potential energy (i.e. fat) it has stored. But leptin is only produced during certain stages of sleep. Miss out on those stages because you’re not resting soundly enough, and you’ll disturb levels of the hormone, leaving your body with no real idea of its energy reserves. Consequently, you’ll end up storing calories rather than burning them.


1. Get clear on what motivates you. “Try to connect with the real reason you want to lose weight,” says Jonny Bowden, PhD, a Los Angeles-based board-certified nutritionist. “Beyond a slimmer waist, what do you really want? Is it more energy? Better sleep? More mental clarity? The ability to run a block without getting winded?” Once you've identified your goals, write them down. Seeing the bigger picture might help you make better day-to-day decisions, Bowden says.
A reasonable daily diet for an adult is 2,000 food calories. That's 8.36 megajoules per day, or about 100 joules per second -- in other words, 100 watts. Most of that ends up as heat, so you warm a room as much as a bright light bulb. Cut your consumption by 600 calories per day and you'll lose a pound of fat every week. Most diet experts consider that a reasonable goal. Don't drop below 1,000 calories per day, or you might get lethargic. But at 1,400 calories per day, you can easily maintain an active life.
Other Exercises – Ab exercises will also help reduce belly fat and help you keep that tummy tone as you lose the weight. We are a huge fan of core and ab exercises here at Lose Weight by Eating, and consider them the best exercise to lose belly fat. Not only to they help you tone up fast, they also strengthen your back, fix your posture (which makes you look thinner!) and help you lose belly fat!
I put theory into practice. In 2003, I had once again grown out of my belt. I wasn't grossly overweight: 205 pounds in a six-foot, one-inch body. That wouldn't be bad for a football player, but I'm 59 years old, and the excess pounds weren't in muscle. I had gained a pound a year for several decades. I felt heavy and old. I decided to try conservation of energy. I gave up lunch and snacks.
Unsurprisingly, the results showed that nothing had happened to the weight of the women receiving calcium or the placebo. However, the group which took the multivitamin lost more weight – about 3 kg more – and improved their health markers. Among other things, their basal metabolic rate (the rate at which the body burns calories when at rest) increased.
You know that protein's essential for a slimmer you. But here's why protein really needs to play a prime roll on your plate: "Your body starts to produce more insulin as you age, since your muscle and fat cells aren't responding to it properly," explains Louis Aronne, M.D., director of the obesity clinic at Cornell University. Insulin promotes fat storage—especially around your belly—and a diet high in protein may protect you against insulin resistance, says Aronne. In one study, obese women who followed a diet for eight weeks that was roughly 30 perecent protein, 40 percent carbs, and 30 percent fat lost significantly more fat—including visceral pudge—than women who stuck to a plan that was 16 percent protein, 55 percent carbs, and 26 percent fat.
Think sweets are the enemy of weight loss success? Not so fast: dark chocolate might just be your best friend for weight loss (and that doesn't even include these other 5 Health Benefits of Eating Chocolate). Researchers at the University of Copenhagen fed healthy young men 100g of either milk or dark chocolate first thing in the morning, then had them rate their hunger level and fed them a meal of pizza two hours later. They found that the men who had dark chocolate were felt more satisfied after eating the chocolate, were less hungry, and ate less (17 percent fewer calories than the milk chocolate eaters) when offered pizza at their next meal. 
In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
The body doesn't react to all fats in the same way. Research correlates high intake of saturated fat (the kind in meat and dairy) to increased visceral fat, says Patton. On the other hand, monounsaturated fats (the kind in olive oil and avocados) and specific types of polyunsaturated fats (mainly omega-3s, found in walnuts, sunflower seeds, and fatty fish like salmon) have anti-inflammatory effects in the body, and if eaten in proper portions may do your body good. But Patton warns that eating too much fat of any kind increases your calorie intake and could lead to weight gain, so enjoy healthy fats in moderation. 

If you're eating fewer than 1,200 calories per day, your workouts will suffer and the constant stress on your body can lead to muscle loss and slow your metabolism, as we reported in 10 Things You Don't Know About Calories. If you're trying to eat super healthy, you might be surprised at how few calories you're actually eating—try tracking your daily intake with a food tracking app and make sure you're fueling your body, not depriving it of nutrients.
3. Exercise Ball Crunch: This is one of the most effective ways to strengthen and flatten abs.  Studies show this exercise is 40% more effective than regular ab crunches as it targets smaller muscles for flat toned abs including the oblique’s for a small waist and the outermost muscles that your typical ab crunch may miss.  To begin, lie down on the ball positioning it under the lower back.  Place arms behind your head.  Tighten your abs as you lift your torso off the ball while keeping the ball stable.  Lower back down and repeat 15 times with 1-3 sets.

1000 crunches a night may get you strong abdominal muscles, but with a full layer of fat on top, you will not get the results you really want. Instead of all those crunches, do exercises that engage multiple muscle groups and work your cardiovascular system. Try planking, where you hold yourself in a push-up position, resting your forearms on the ground. Try 3 or 4 sets of holding for 30 seconds each. Getting up and moving throughout the day by going for walks will also help.


Those trans fats on your menu are hiding out in plain sight and sabotaging your lean belly plans every time you eat them. If a food product says it contains partially hydrogenated oils, you’re eating trans fat, which can increase your risk of heart disease, high cholesterol, and obesity with every bite. In fact, research conducted at Wake Forest University reveals that monkeys whose diets contained eight percent trans fat upped their body fat by 7.2 percent over a six-year study, while those who ate monounsaturated fat gained just a fraction of that amount. Instead of letting harmful trans fat take up space on your menu, fill up with the 20 Healthy Fats to Make You Thin.
