The SAID principle
The SAID principle is simple—it stands for Specific Adaptation to Imposed Demands. This training principle basically states that if you want to get better at something you must do that something over and over until you are better at it. If you want to play baseball like Derek Jeter then you must play baseball, a lot. If you want to be as good at CrossFit as Rich Froning Jr. then you must put in the time like he has.
This is your body adapting to the imposed demand place upon it. The SAID principle not only relates to things in the gym but all aspects of life, including diet, sleep, school, etc. This really relates to your diet, if something is not working and you are not seeing the results you are looking for change the demands placed on your body by changing your food choices to base your diet on vegetables, lean meats, nuts and seeds, some fruit, little starch and no sugar. Keep intake to levels that will support exercise but not body fat. If you are not seeing results and you are tracking your diet, then change ratios and how often you eat maybe you need to be more consistent with your training? There is no one right way to reach your goals, there are thousands. Use the SAID principle to your advantage.
