Is it important to stick to the plan?
Generally chronic health problems do not suddenly develop overnight. They develop over a long period of time (often years) with improper diet (which cause nutritional deficiencies and imbalances) and environmental influences. All of which have gotten you into your current health condition.
Therefore, the sooner and more thoroughly you implement your program, the sooner you will start to see results. While on your program, if you continue those some old habits and routines that contributed to your current condition, your body's condition may not improve as you hope. Total commitment to your program is strongly urged.
