Fat acids are a substrate for cholesterol, meaning that fatty acids must be available to create cholesterol. This is important because cholesterol is eventually converted to testosterone. If fat intake is too low there will not be enough fatty acids available for optimal testosterone productions. This will lead to an even lower level of testosterone.
High carb days need to be inserted into your fat loss plan regularly to prevent a metabolism stall, but high carb days cannot be taken too frequently without slowing progress. The frequency with which to take high carb days will depend on how fast your metabolism is and how lean you are. Below is the guide for determining the frequency of high carbs days based on body type.
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.
