Exercising at lower intensities will use more fat for energy. This basic premise is what started the theory of the fat burning zone, which is the idea that working in a certain heart rate zone (around 55 to 65 percent of your maximum heart rate) will allow your body to burn more fat. Over the years, this theory has become so ingrained in our exercise experience that we see it touted in books, charts, websites, magazines, and even on cardio machines at the gym.
At its core, burning fat comes down to the process of lipolysis—the breaking down of fat lipids, explains Seedman. This happens in the mitochondria of the muscles, or the powerhouses of the cells, responsible for generating the energy our cells need to do their jobs. Exercise has been shown to improve mitochondria function, which then promotes fat breakdown, Seedman adds. Plus, working out helps regulate pretty much all the hormones that optimize fat loss.
Maybe you are trying too many things. If you keep switching diets and are doing too much exercise, your body is trying to balance itself. it might also be caused by lack of sleep or too much stress. Do moderate exercise and start eating a little bit cleaner and the pounds will come off. If you still don't notice a difference, talk to your doctor. You might have a thyroid problem or some other medical issue.
Drink cold water: Staying hydrated period is important to keep your systems sharp, but adding ice to your water can help give your fat-burning potential a boost. German researchers found that drinking six cups of cold water can raise your BMR—that’s your resting metabolism—by roughly 50 calories a day because your body has to work to heat the H2O to body temperature.
A big part of weight loss is simply being aware of the decisions you’re making. For example, when out at happy hour with friends, you may lose track of how much you're eating or drinking. But if you take a split second to step back and become aware of that fact, you’re more able to course correct. “The awareness and then planning for what else I can be doing, that might give me the same benefit of eating comfort foods,” says Gagliardi.
While the old thinking was that steady-state cardio sessions were best for burning fat, we now know that short and intense bursts of fast-paced cardio is much more effective. Hope Pedraza, an ACSM personal trainer and the creator of inBalance, a San Antonio-based fitness and wellness studio, suggests doing intervals that alternate between exercises that work different muscle groups.
Break up your workouts. Your metabolism spikes after every bout of physical activity. So if you can break up your hour workout into two half-hour chunks, you'll get two spikes instead of one. Your body burns calories at a higher-rate after a workout (sometimes for several hours after), and if you rejuvenate it later in the day, you'll further enhance the effect.
Certain energy drinks have been shown to boost fat loss. University of Oklahoma (Norman) researchers reported in a 2008 study that when 60 male and female subjects consumed a diet energy drink containing 200mg of caffeine and 250mg of EGCG from green tea extract for 28 days, they lost more than one pound of body fat without changing their diets or exercise habits.
Cut back on calories. The most important part of losing weight is not working out until you collapse — it's your diet. If you burn 500 to 750 more calories than what you eat every day, you will lose 1–2 pounds every week (any more than that is considered unsafe weight loss). There are tons of little changes you can make to cut calories from your diet, from replacing high-calorie dressings with vinaigrette and asking for all dressings/sauces served on the side, eating at the table instead of in front of the tv, skipping cheese and other fatty additions to your salads and meals, using smaller plates, leave off the whipped cream on your coffee drink, and on and on.
