Sure, ketchup is tasty, but it’s also a serious saboteur when it comes your weight loss efforts. Ketchup is loaded with sugar — up to four grams per tablespoon — and bears little nutritional resemblance to the fruit from which it’s derived. Luckily, swapping out your ketchup for salsa can help you shave off that belly fat fast. Fresh tomatoes, like those used in salsa, are loaded with lycopene, which a study conducted at China Medical University in Taiwan links to reductions in both overall fat and waist circumference. If you like your salsa spicy, all the better; the capsaicin in hot peppers, like jalapeños and chipotles, can boost your metabolism, 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.
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.
At the same time, wearing clothes you can actually move in (read: not stilettos and a tiny pencil skirt) to work might help keep you active during the day instead of parked at your desk. A study by the American Council on Exercise found that people took an average of eight percent more steps on days that they wore jeans instead of conventional business clothes. You officially have a health excuse to ask for casual Friday every day.
And as people get older they tend to become less active, which means you burn fewer calories all day long. Plus, you naturally lose muscle mass due to hormonal changes, which further drops your daily calorie-burn rate. Muscle tissue burns more calories than fat tissue, so a body with less lean tissue has a lower metabolism and is prone to weight gain.
And while the weight room can be intimidating for women, pumping iron is key to getting a toned and fit physique. Don’t worry, lifting heavy weights won’t make you bulky — you just don’t have the testosterone to build the size of a man. Lifting will improve your posture, make your arms, core and lower body more shapely and boost your metabolism by building muscle. Resistance training also helps you hold onto muscle that you naturally lose as you age.
The main advantage of the low-carb diet is that it causes you to want to eat less. Even without counting calories most overweight people eat far fewer calories on low carb. Sugar and starch may increase your hunger, while avoiding them may decrease your appetite to an adequate level. If your body wants to have an appropriate number of calories you don’t need to bother counting them. Thus: Calories count, but you don’t need to count them.
While many people turn to artificial sweeteners in a misguided attempt to whittle their waistlines, those fake sugars are likely to have the opposite effect. According to researchers at Yale, artificial sweeteners are actually linked with an increased risk of abdominal obesity and weight gain, possibly because they can trigger cravings for the real stuff and spike insulin levels in a similar fashion to real sugar.
