Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index (for instance, asparagus is lower on the glycemic index than a potato) or lower in carbs per serving than others. Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. They may be added back, such as in “enriched” bread.
Yes, there is rest built in—two days, to be exact—but not until you’ve put in seven straight days of pedal-to-the-metal work. Rest on days 8 and 13 to allow your body to temporarily recover from the grind of the program. This will help you bank more energy for the work days that follow. These rest days are mandatory. For those of you hitting the panic button, don’t fret—12 out of 14 days at these intensities will still be plenty adequate for getting your shred. Remember: your body changes while it recovers, not while you train. So, consider these two days your chance to bust into the gym a little more ripped on days 9 and 14.
After somewhere between three and five hours, your body stops processing its last meal. There's nothing left to absorb, so insulin levels naturally decrease. Then, somewhere between eight and 12 hours after that last meal, your body starts burning stored fat. (Why don't you start burning fat sooner? Biology is sometimes a pain in the ass; it's like our bodies will do anything to hang on to fat.)
Physical activity helps burn abdominal fat. “One of the biggest benefits of exercise is that you get a lot of bang for your buck on body composition,” Stewart says. Exercise seems to work off belly fat in particular because it reduces circulating levels of insulin —which would otherwise signal the body to hang on to fat—and causes the liver to use up fatty acids, especially those nearby visceral fat deposits, he says.

Your body uses two primary nutrients for fuel: glucose and ketones. Most people use glucose for fuel; this is because the average person has a carbohydrate based diet. If you want to burn fat fast as hell, however, put your body into a state of ketosis. What this means is that your body’s primary source of energy is no longer carbohydrates, but fat. In other words, you’ll literally be burning your own fat supplies for energy.
The scale is not necessarily your friend. You may want to lose fat – but the scale measures muscles, bone and internal organs as well. Gaining muscle is a good thing. Thus weight or BMI are imperfect ways to measure your progress. This is especially true if you’re just coming off a long period of semi-starvation (calorie counting), as your body may want to restore lost muscles etc. Starting weight training and gaining muscle can also hide your fat loss.
"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."
