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.
But you’ll likely experience some benefit before then. Fiber helps slow down your digestion and requires more chewing, which helps signal to your body that it’s full, keeping your hunger in check throughout the day. One small study published in Food & Nutrition Research actually found that men who ate meals rich in high-fiber foods, like beans and peas, felt more satisfied than those who focused only on protein-rich foods, like pork and veal. Adult women should aim to eat 25 to 28 grams of fiber per day.
While the Duke study found no added benefit to resistance training (aka weight or strength training) when it comes to belly fat, a 2014 study from a Harvard University team found otherwise. Twenty minutes of weights a day was linked to less of an increase in belly fat (particularly for older men). “Engaging in resistance training or, ideally, combining it with aerobic exercise could help older adults lessen abdominal fat while increasing or preserving muscle mass," said the paper’s lead author Rania Mekary.
Limit your use of saturated fats. Saturated fats to avoid are found in meats and high-fat dairy products such as cheese, milk (and cream), and butter. Some plant-based oils, such as palm oil, palm kernel oil and coconut oil, also contain high levels of saturated fats. Polyunsaturated fats are a better alternative. Polyunsaturated fats are found in many nuts, seeds, avocados, and some fish.
Like protein, fiber slows the rate at which your body plows through carb calories so you feel full for longer and maintain steadier blood sugar levels, one reason why research consistently links fiber intake to weight loss. That means fibrous whole grain bread tends to be a better choice than white bread and also explains why fruits, which contain fiber and valuable vitamins in addition to sugar, beat straight-up candy every time.
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.
Awesome news: Turns out marathoning for an hour on the treadmill isn't only boring as hell, but it doesn't even give you that great of a workout. Experts say if you're trying to flatten your abs, one of the most effective methods is actually interval training, which means incorporating short bursts of high-intensity burnouts into whatever you're doing, whether that's running, squats, whatever. And bonus — it'll keep you burning calories for up to 16 hours post-exercise. Um, we'll take it.
It can actually help you cut back on calories. That's because capsaicin, a compound found in jalapeno and cayenne peppers, may (slightly) increase your body's release of stress hormones such as adrenaline, which can speed up your ability to burn calories. What's more, eating hot peppers may help slow you down. You're less likely to wolfed down that plate of spicy spaghetti —— and therefore stay more mindful of when you're full. Some great adds: Ginger, turmeric, black pepper, oregano, and jalapenos.
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.
Folks with fluctuating blood sugar levels are more likely to have belly fat than folks whose sugar levels are relatively steady. Try taking daily supplements of 750 mg to 1,500 mg of glucomannan, a Japanese root extract that can help you shed up to six pounds of belly fat in two months, Columbia University scientists say. (Important: Be sure to check with your doctor first.)
If you want to work late at night, think again. When your biorhythms are off, you end up eating more. When you're tired you produce more ghrelin, which triggers cravings for sugar and other fat-building foods. Losing sleep can also alter your hormone production, affecting your cortisol levels that cause insulin sensitivity, prime reasons for belly fat! Getting about 7 hours of sleep a night is one of the best things you can do for your body shaping goals.
The researchers hypothesize that participants who abstained from animal products dropped significantly more pounds since plant-based foods include loads of filling fiber and slow-to-digest complex carbs. Though more research is needed to confirm these results, the study authors write, "Vegetarian diets appeared to have significant benefits on weight reduction compared to non-vegetarian diets."
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.
