Shaping is a behavioral technique in which you select a series of short-term goals that get closer and closer to the ultimate goal (e.g., an initial reduction of fat intake from 40 percent of calories to 35 percent of calories, and later to 30 percent). It is based on the concept that "nothing succeeds like success." Shaping uses two important behavioral principles: (1) consecutive goals that move you ahead in small steps are the best way to reach a distant point; and (2) consecutive rewards keep the overall effort invigorated.
What can work like magic, though, is simply eating fewer calories than you're burning. It's pretty easy to do that every now and then. It's when you try to do it for weeks and months that things get a little trickier. By incorporating insight gained from research-backed fat-loss strategies, you have a better shot at losing the weight you want without compromising your fitness or health.

However, due to the intense exercise, the total calorie consumption is higher. We burn more calories due to the hard muscle work – even AFTER the run. The body needs more energy for recovery, thereby burning even more calories. That’s how you benefit from post-workout fat burning and the afterburn effect (EPOC, excess post-exercise oxygen consumption).
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.
