A diet that’s low in fat and carbohydrates can improve artery function, according to a 2012 study by Johns Hopkins researchers. After six months, those on the low-carb diet had lost more weight, and at a faster pace. But in both groups, when weight was lost—and especially when belly fat shrank—the arteries were able to expand better, allowing blood to travel more freely. The study shows that you don’t have to cut out all dietary fat to shrink belly fat. For heart health, simply losing weight and exercising seems to be key.
The upshot of all these chemicals floating around is big trouble for big-bellied guys. In a study at the University of Alabama at Birmingham, researchers took 137 men of all ages and sizes and used seven different measurements to determine their risks of cardiovascular disease. The single best sign of multiple heart-disease risks? No, it wasn't the guys' family histories or their cholesterol profiles. It was the amount of abdominal fat they carried.

Real talk: It could take weeks or months to see the metabolic effects of exercise on the scale, and even then, building muscle, which is denser than body fat, could lead to weight gain. "Do what you like because it’s good for you," Dr. Seltzer says, noting the way exercise is awesome for your heart, mental health, and more—and that not all measure of progress can be seen on the scale.
Although you won't be able to completely transform your body or even lose more than a few pounds in a month, you can jump-start your weight-loss journey and be well on your way to achieving your goals. Just be mindful that while you can lose weight in a month, you can't specifically target your belly; there's no such thing as being able to spot-reduce fat (your body decides where the fat comes from - yay, genetics!). We tapped registered dietitian and ACSM-certified personal trainer Jim White, who owns Jim White Fitness and Nutrition Studios and helps clients reach their weight-loss goals, for insight on how to lose belly fat in 30 days.
“For some people, it’s knowing, ‘Typically I eat a whole sandwich,’” says Gagliardi. “‘Now, I’m going to make the decision to eat half a sandwich at lunch and save the other half for my dinner and essentially cut my calories in half. And they feel good about that. They’re not having to do math.” To get started, check out these 25 simple ways to cut 500 calories a day.
Don’t buy your tickets to Bonnaroo just yet; the kind of acid that will help you slim down is the stuff right inside your cabinet. A 12-week study published in Bioscience, Biotechnology, and Biochemistry reveals that obese study subjects who made vinegar part of their diet dropped more belly fat than a control group, and other research suggests that acidic foods, like vinegar, can increase the human carbohydrate metabolism by as much as 40 percent.
A study in Psychosomatic Medicine confirms the link between stress and weight gain, revealing that women who are most vulnerable to the effects of stress are more likely to have excess abdominal fat and higher levels of the stress hormone cortisol. One reason could be that women tend to eat more, especially sweets, on days they are stressed, according to a study in the journal Psychoneuroendocrinology.
There are different types of HIIT but an easy one to begin with is to simply warm up for 3 minutes on an elliptical machine or by walking.  Then work out for 30 seconds so that at the end of the exercise you feel satisfied.  Reduce the speed to slow down to a moderate pace.  Do this 7 more times or for total 8 intervals. Start with one interval and as your body is ready to take more increase the intervals.  Studies show that HIIT to be the absolute premier cardio for weight loss and optimal health as compared to longer, traditional cardio.
The truth is there is no “one size fits all” solution to permanent healthy weight loss. What works for one person may not work for you, since our bodies respond differently to different foods, depending on genetics and other health factors. To find the method of weight loss that’s right for you will likely take time and require patience, commitment, and some experimentation with different foods and diets.
For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.

Somewhere between a 3 and a 4. No, I have not tried the diet, and I'm not sure it's the diet for me. But I do know people who have been successful on it. What bothered me the most is that everyday for 6 weeks, all 4 meals and 3 snacks are spelled out, and on many of these days, the choices are the same, so the book continues to repeat itself over and over. The same rules are repeated over and over too. The smoothie and protein shake recipes look good. I wish there had been some suggestions for p ...more
If you're specifically looking to target your belly, we have some bad news: you can't spot-target fat loss. That means you can do crunches or planks all day long, but you won't specifically burn belly fat. Instead, you can lose body fat overall, including from your belly. And by avoiding certain belly-bloating foods and with some strategic exercise, you will inevitably see results in your belly.
2. Ab Plank is a great exercise to really challenge your entire core and build up your strength and endurance. The Plank works the lower abdomens, the oblique muscles and your lower back. It takes focus and concentration plus some upper body strength. Start with holding the plank position for 30- 40 seconds and build your way up. You will be amazed at how strong your cores will get by doing this exercise regularly.
Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. Plus, it'll help you relax post-meal so you won't be tempted by stress-induced grazing that can rack up calories.
And that raises the most important point: Thinking about exercise as a way to work off food or simply allow you to eat sets up a host of unhealthy and unhelpful thought patterns and habits around food and exercise. For instance, one 2013 research review found that, not only did people generally overestimate how many calories exercise burned—when they did work out, they ramped up their food intake. And if you overeat following exercise, any caloric deficit created during your workout can become a wash. And related: thinking of food as a reward and exercise as a punishment is likely to sabotage your weight loss efforts anyway.
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.
If you eat a carbohydrate-rich meal (lots of pasta, rice, bread, or French fries, for example), your body releases insulin to help with the influx of all this glucose into your blood. As well as regulating blood sugar levels, insulin does two things: It prevents your fat cells from releasing fat for the body to burn as fuel (because its priority is to burn off the glucose) and it creates more fat cells for storing everything that your body can’t burn off. The result is that you gain weight and your body now requires more fuel to burn, so you eat more. Since insulin only burns carbohydrates, you crave carbs and so begins a vicious cycle of consuming carbs and gaining weight. To lose weight, the reasoning goes, you need to break this cycle by reducing carbs.

Choose Liquid Calories Wisely. Sweetened drinks pile on the calories, but don't reduce hunger like solid foods do. Satisfy your thirst with water, sparkling water with citrus, skim or low-fat milk, or small portions of 100% fruit juice. Try a glass of nutritious and low-calorie vegetable juice to hold you over if you get hungry between meals. Be careful of alcohol calories, which add up quickly. If you tend to drink a glass or two of wine or a cocktail on most days, limiting alcohol to the weekends can be a huge calorie saver.


If you want to shrink your gut, get enough protein in your diet. In this case, about 25 percent of calories. Why? For starters, protein makes you feel full and helps you build muscle (which increases metabolism, thereby making it easier to lose weight). Just as important, high-protein diets have been shown to be the best way of attacking belly fat. In one study, published in the International Journal of Obesity, Danish researchers put 65 people on either a 12 percent protein diet or a 25 percent protein diet. The low-protein dieters lost an average of 11 pounds, which isn't bad. But the high-protein subjects lost an average of 20 pounds--including twice as much abdominal fat as the low-protein group.
As said before, measuring your waist with the tape is the easiest way to check belly fat. Measure your torso at the level of your navel. As per the official guidelines, measure your abdomen from just above the hip bone or the iliac crest, just where it intersects the line dropping down from the middle of the right armpit. Breathe normally while taking the measurement, and don’t hold the measuring tape too tight against the skin. Those with a waist size more than 33 inches are at risk of developing chronic heart disease.
To start off, aim to do ab work 3 or 4 times a week on non-consecutive days with at least 24 hours of rest in between sessions, says Gagliardi. During those sessions, you can start with simpler moves like crunches, bicycle crunches, and planks. Even though you may only be directly targeting your abs 3 or 4 times a week, you should still be activating your core (aka, tightening your ab muscles) in every workout you do, says Gagliardi.
I followed this diet all the way through and have mixed feelings. I lost about 7 lbs and would have liked to lose more. I did feel it got me into better eating habits and working out on a regular basis but it is a very extreme diet and hard to maintain after the 6 weeks. I also feel like there is a lot of fruits and juices that you eat and drink. A lot of sugars even though they are natural sugars.
It’s true that a caloric deficit—burning more calories per day than you take in—is a requisite of weight loss. But creating a deficit doesn’t have to (and shouldn’t) involve deprivation. That goes for calories, carbs, sugar, fat, or any other commonly demonized nutrient. “No one food is responsible for your weight,” Langer says, explaining that a good vs. bad mentality sets people up for disordered eating and exercise habits. In fact, caloric deprivation increases how the brain responds to food, setting you up for binge-eating down the line, according to research from the Oregon Research Institute.

It’s possible you’ve lost significant fat already with foods like milk, wheat bread, and artificial sweeteners in your diet, but for the next week, cut these out entirely—even if you don’t think you have an intolerance to them. Even the slightest irritation to your digestive system can cause bloating and water retention, so eliminate the risk completely. Dairy and gluten appear in numerous condiments (soy sauce, salad dressings, some brands of barbecue sauce, etc.), so to avoid a potential problem, read labels and control your intake as much as possible. Season your food with condiments such as sea salt, salsa, and balsamic vinegar instead.
Trim Portions. If you did nothing else but reduce your portions by 10%-20%, you would lose weight. Most of the portions served both in restaurants and at home are bigger than you need. Pull out the measuring cups to get a handle on your usual portion sizes, and work on paring them down. Get instant portion control by using small bowls, plates, and cups, says Brian Wansink, PhD, author of Mindless Eating. You won't feel deprived because the food will look plentiful on dainty dishware.

Nuts. It’s very easy to eat until the nuts are gone, regardless of how full you are. A tip: According to science, salted nuts are harder to stop eating than unsalted nuts. Salted nuts tempt you to more overeating. Good to know. Another tip: Avoid bringing the entire bag to the couch, preferably choose a small bowl instead. I often eat all the nuts in front of me, whether I’m hungry or not.
"Crash diets (dramatically cutting down how much you eat) might help you to lose a few pounds at first, but they’re hard to sustain and won’t help you keep the weight off. It might seem like a quick and easy option, but eating too few calories can actually do more harm than good. If your calorie intake dips too low, your body could go into starvation mode. This will slow down your metabolism, making it harder for your body to lose weight. Make sensible, healthy changes to your lifestyle that you can stick to and avoid the fad diets."
