Digestive metabolism, or thermic effect of food (TEF): Simply digesting food—turning carbs into sugar and turning protein into amino acids—typically burns 10 to 15 percent of your daily calories. Digesting protein burns more calories than digesting carbohydrates or fat—about 25 calories for every 100 consumed. Digesting carbohydrates and fat burns about 10 to 15 calories for every 100 consumed.

Carbs are always perceived as the enemy, but they too have a significant role in fat loss. The body needs glucose to work, and to a certain level, your brain requires it to think and function optimally. Some will argue that technically we don't need carbs, but many of your body's basic functions will decrease in performance without the right amount of carbs at the right times.
Weight gain has been associated with excessive consumption of fats, (added) sugars, refined carbohydrates in general, and alcohol consumption.[citation needed] Depression, stress or boredom may also contribute to weight increase,[5] and in these cases, individuals are advised to seek medical help. A 2010 study found that dieters who got a full night's sleep lost more than twice as much fat as sleep-deprived dieters.[6][7]
We call it a beer gut for a reason: Your body tends to prioritize getting rid of any alcohol in your system, so it targets those calories first, which may impede fat burning, explains Hultin. Alcohol also tends to be higher in calories (7 per gram), and its inhibition-dissolving tendencies may lead you to overeat. Lose the booze, and you’ll likely lose more weight, too.

The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.


Stress wreaks havoc on every part of your body, and can lead to breakouts, joint pain, headaches, and yes, even excess belly fat. That’s because when you’re stressed, your body pumps out extra cortisol, that not-so-great hormone you keep hearing about. Studies show that cortisol not only spikes your appetite, but may also redistribute body fat to your belly area, according to a review published in the journal Obesity.
Carbohydrates are essential to keeping a fast metabolism. Leptin and other fat burning hormones are directly related to carbohydrate intake and body fat levels. Leptin is a fat burning hormone that serves many functions. One of the most important functions is the control of energy expenditure. When food intake, and most notably carb intake is high, leptin levels will be high. This sends signals to you body that it is in a fed state and this can cause your metabolism to remain high.

If your fitness goals include a flatter belly and stronger core, you're going to need a solid plan, expert guidance, and a little outside motivation. Our 30 Days to a Flat Belly plan has all three! This comprehensive workout plan will give you results you want without a pricey gym membership; you can do these workouts anywhere — and they're all 30 minutes or less.
"When we’re lacking in sleep, our body’s hormones get thrown off balance which can impact our hunger levels the next day. We all have two hormones that affect our appetite: ghrelin and leptin. When we don’t get enough sleep, our ghrelin levels (the hormone that makes us feel hungry) rise, and our leptin levels (the hormone that makes us feel full) drop. This means that when we’re awake, we tend to eat more but feel less satisfied. Try going to bed a little earlier than usual to avoid this imbalance and remember to remove any distractions that might prevent you from nodding off."

Our increasingly slothful lifestyles are partly to blame for skyrocketing obesity rates, so it’s no surprise that being more active is a simple fix for belly fat. In 2003, a first-of-its-kind study from Duke University showed that sedentary adults accumulated abdominal fat surprisingly quickly — and that sedentary women stacked on fat more visceral fat than sedentary men, even though they added less fat overall.

But if you're trying to get ripped, you must minimize your consumption of fat. Protein, on the other hand, not only adds to your muscle—key in boosting the metabolism—but actually increases your metabolism more directly. The body burns more calories processing protein than it burns to process carbs or fat, known as the thermic effect of food. That's the main reason diets that include a lot of protein result in greater fat loss than low-protein diets, even when both diets contain the same amount of calories.


Weight training can sometimes seem like an afterthought in many fat loss plans. This is a huge mistake since weight training burns an incredible amount of calories and raises the metabolism for hours after training. Many people mistakenly believe that the best way to lose fat is to stop lifting weights and focus on cardio. This will cause you to lose weight but most of it will not be fat.

6. Fast once a week: While regularly underfeeding your body completely messes with your hormone balance, there’s sufficient research to suggest that intermittent fasting (IF)—or going without any food for set intervals—can actually help your insulin sensitivity and burn more fat. Researchers at LSU, for example, found that when people fasted all day, every other day, their fat oxidation increased and they actually lost 4 percent of their body fat in just 22 days. There are a lot of ways to go about IF, from fasting for 12 to 16 hours every day, to going 24 hours once a week. (Learn more about it here.)
This question is on so many minds: how can I lose belly fat...and fast? While there's no magic formula of food and exercise to reduce belly fat with the snap of your fingers, there are nutrition choices, exercises and lifestyle changes that can help. Here's your guide to understanding exactly what belly fat is and how you might be able to reduce it over time.
To understand how far I have come in these 6 weeks, you would have to understand where I started. I weighed 210 lbs. This is the biggest I had ever been. I was lazy, never worked out and ate like crap. When I got married I weighed 140. That was 12 years ago. After having 2 children, like many moms, I just let myself go. My diet consisted of lots of fast food and lots of junk food. My daily routine included stopping at a fast food restaurant for a biscuit and large sweet tea every day on my way to work. I knew I was slowly killing myself. I was completely disgusted by the way i looked and felt, but I never made myself do anything different. In the past I had done all of the fad diets....weight watchers, low carb, low calorie, whole 30. I could do anything for a few weeks, but knew it was not something I would maintain in the long run. My weight constantly went up and down. About 8 weeks ago, my new friend Stacy shared with me about this program. She showed me her before and after pics. She assured me this was life changing and that I could do it. After much thought I jumped in and I am so glad I did. For 6 weeks I have worked out consistently. I have eaten so much better. Because of this I feel so much better! 
This could be because the body increases insulin secretion in anticipation that sugar will appear in the blood. When this doesn’t happen, blood sugar drops and hunger increases. Whether this chain of events regularly takes place is somewhat unclear. Something odd happened when I tested Pepsi Max though, and there are well-designed studies showing increased insulin when using artificial sweeteners.
I have struggled with my weight and binge eating my entire life. Finally, at 49 years old, I have found a lifestyle - the FASTer Way to Fat Loss lifestyle - that works with me and my busy life. I am a busy full time professional and I travel quite a bit. Never knowing where I am, I am able to do the workouts and eat following the guidelines of the plan from anywhere. I knew I had experienced a major mind set shift over the weekend when I came across an old bottle of prescription diet pills I had been hanging onto as a crutch. I no longer need those and never would consider taking those now that I have taken control of my body and changed my mindset. Eating real whole food and moving my body consistently has led to this transformation from a size 10-12 to a size 6. I'm wearing clothes I haven't worn in years. Most importantly, I don't have a deadline to get weight off or see a certain number on the scale as I used to. I am trusting that my body will continue in its transformation until I lose this excess body fat. I am halfway there, and I know I'll be successful. I no longer have the mindset that I have to be perfect in my eating. I used to fall off the wagon and literally binge for three days and then feel horrible. Progress, not perfection. Thank you for that mantra, Amanda, and for creating this wonderful program. I am so thankful that I discovered this program and can continue to enjoy it with VIP membership now that I've completed two 6 week cycles.

According to a small study published in the journal Annals of Internal Medicine, people who slept for 8.5 hours a night for two weeks lost nearly twice as much weight on average than participants who slept 5.5 hours per night, despite the fact that they followed the same diet and workout plan. That's because when you get a good night's sleep, your hunger hormones, like ghrelin and leptin, stay in check. That means you're not going to wake up with a sudden hankering for a bacon, egg, and cheese. (Start working towards your goals with Women's Health's Body Clock Diet.)


I'm more toned and I can pull my skin away from my muscle (whereas before it was fat). I love that I DO workout hard, but it's not the kind of hard that I used to do, where you work out until you want to throw up, or can't sit down for 2 days because you're so sore. I couldn't do that in this stage of life so this program really works for me. I was able to jog (and I HATE running) the other day, because I had the energy and the muscle strength to support that kind of movement. The only negative thing about this program is that I have to buy a ton of new clothes!! :-)
Protein is a must for any weight loss plan, but it doesn’t always have to come from meat. Beans and legumes are a fantastic alternative because they tend to be lower in calories and fat, and high in filling fiber as well as protein. Swapping them in for meat has been shown to boost weight loss and can burn fat fast. Next, check out these 50 ways to lose weight without a lick of exercise.
Of course, not all carbohydrates are equal. In short, fast-digesting carbs tend to create a large insulin burst, leading to more potential fat gain. These carbs include white bread, most cold cereals, any sweets, rice cakes, white rice, and white potatoes. Conversely, slow-digesting carbs (found in whole-grain breads, oatmeal, sweet potatoes, and legumes) don't cause much of an insulin rise, so these should make up the vast majority of your carb consumption.
Digestive metabolism, or thermic effect of food (TEF): Simply digesting food—turning carbs into sugar and turning protein into amino acids—typically burns 10 to 15 percent of your daily calories. Digesting protein burns more calories than digesting carbohydrates or fat—about 25 calories for every 100 consumed. Digesting carbohydrates and fat burns about 10 to 15 calories for every 100 consumed.
If you ate nothing but Twinkies or apples for a few months, you'd probably lose weight. You'd also lose muscle mass and gym performance—and threaten your overall health. Your goal is to build a healthy diet that gives you the right amount of macros (proteins, carbohydrates, and fats) that will sustain you over that time. Let's look at these macros one at a time.

On high carb days protein intake should be lowered to 0.95 gram per pound of body weight. To calculate this you must multiply your body weight by 0.95. This means if you weigh 180 lbs. then on your high carb days you should eat 180 grams of protein. Don’t worry about losing any muscle mass as a result of lowering protein. The higher insulin levels from the extra carbs will be more than enough to preserve muscle.


"Only doing abdominal-focused workouts, like crunches, won’t help you banish the bulge. Belly fat is simply where your body stores energy, so you need to take a whole-body approach to tackle it. HIIT training (high intensity interval training) is a great way to burn fat and get your heart rate up. Squats, burpees and treadmill sprints are all examples to try."

When trying to build and maintain muscle mass, adequate protein intake is a must. The best choices for protein are lean animal proteins. Protein that is not derived from an animal source is that it is considered an incomplete protein. This means that it lacks certain essential amino acids necessary to build muscle. Here are some of the best choices choices for protein:
This formula will help you lose weight faster, says Kristin Kirkpatrick, R.D., manager of wellness nutrition services at the Cleveland Clinic Wellness Institute. A 2016 study published in the American Journal of Clinical Nutrition suggests that increasing your protein intake while decreasing the amount of calories you consume ensures that you lose fat instead of muscle. This 35-35-30 breakdown doesn't mean you can eat any old carb or fat though, she says. Aim to get most of your healthy fat from nuts and fish, your carbs from beans and whole grains, and protein from lean sources like eggs, chicken, and fish, she says.

Water isn’t just a calorie-free beverage, it’s also essential to the process of metabolizing fat, known as hydrolysis, says Pence. So it’s important to drink enough fluids every day—and you’ll need even more if you’re overweight. A good rule of thumb is to drink a milliliter of water for every calorie you consume. Not into the metric system? If you’re following a 2000-calorie diet, that comes to 67 ounces or just over a half gallon of water.
