"Caffeine causes the body to rely more on fat for fuel during a workout, rather than glucose," Aceto says. "But the caffeine effect is lessened when you eat a high-carbohydrate meal with it." Drink 1-2 cups of black coffee within two hours of working out, and emphasize healthy fats and protein if you're drinking it with a meal or snack. Skip the cream and sugar (which add unwanted calories and fat), and avoid drinking coffee at other times of the day; doing so can desensitize you to the fat-burning effects of caffeine.
Another win for your morning cup of joe: Caffeinated coffee keeps things moving through the digestive tract. Since staying regular is key to a tighter-looking tummy, drinking about 8 to 16 ounces of java at the same time every day can help you stay on schedule. Remember: Sugary drinks can lead to weight gain, so skip fancy flavorings and synthetic sweeteners containing sugar alcohols, which can cause bloating.
It seems like 75% of the people come into to my office, and 90% of women and want to lower body fat %, cannot diet effectively forever and at times the best long term solution for reviving metabolism is to put on some good old fashion muscle! Remember that a long term diet especially with low caloric intake will actually teach the body to store fat to preserve survival. If you have been dieting for an extended period of time with poor results, a sluggish metabolism may be to blame! No ladies you are not going to pack on 20 lbs of muscle overnight, that is not going to happen without the right genetics and efforts to do specifically that, however some gains in muscle, say even 5 lbs can help you burn many more calories 24x7 while improving your hormonal landscape as well. Remember more muscle also helps with long term bone health and every day function.

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.


While it is technically correct that cardio activity will use fat to fuel energy output, this process usually only lasts as long as the session itself, and because we gradually adjust to certain levels of intensity the body increasingly resists shedding unwanted weight when routinely using this method: this is why varying one's cardio intensity levels is mandatory if we wish to optimize fat loss. Weight training, however, will work one's body much more intensely than most forms of cardio will, thus stimulating a greater metabolic response, which will ultimately lead to increased fat loss above and beyond that directly attributable to aerobic work.
Before we answer those questions, it’s important to understand how fuel (carbs, fat and protein) is transformed into energy and in which cases they are stored as fuel. To be used by our cells, the different types of fuel must go through several stages of transformation to become the one and only form of  “usable” energy: adenosine triphosphate — more commonly referred to as ATP. ATP is the universal energy currency for many living organisms from mammals to insects and fungus to plants.

To cut calories and lose weight, you have to eat right. That means no empty calories from unhealthy foods, including chips, cakes and cookies. Skip foods that contain simple carbohydrates and eliminate soda altogether. By drinking water and avoiding breads, you may reduce your caloric intake enough to lose weight. If not, opt for vegetable dishes over meat-based ones and choose non-fat dairy when you can.
Avoid Junk Food – While you are at it, make sure that you do not eat junk food by any chance. By eating junk food, you are creating your chances of getting slim, very slim. Junk food like fries and burgers and flavored sodas are the worst enemy when you are aiming to lose weight. Instead of snacking on these, you must eat nuts, and fruits when feeling hungry. https://www.youtube.com/watch?v=TyXnVTALGM0
