Consider someone fifty pounds overweight. Using the quick and dirty formula for caloric need (11 calories/pound), that amounts to 550 calories per day to maintain that excess fifty pounds. Now, considering nothing else than the first laws of thermodynamics (calories in=calories out), that someone will have to go on a “diet” that is 550 calories less than what they are currently consuming.
At the end of the “diet,” what would be the most logical maintenance mechanism? Continuing on the diet, of course, forever. If you go back to doing what you were before, there is only one outcome–regaining the weight commensurate with your caloric consumption and daily activity.
A problem arises when the “diet” is not valid long-term, which I allude to in the previous post. If you don’t have ownership of your diet, if it is foreign and not your own, then the risk of recidivism is much higher. This is why I think that you need to have a direct knowledge of the caloric content, carbohydrate and protein content of the foods you eat as opposed to a “system” that gets between you and your energy consumption.
Don’t forget that there are many variables; Diet Induced Thermogenesis, daily exercise (aerobic and resistance training) to elevate your BMI, the timing of meals, and other strategies addressed in the book, all of which will facilitate both weight-loss and maintenance; because, for all my grousing about calories in and calories out, it is obviously more complex than that.
A strategy, implied in the above, that would be helpful for maintenance would be the addition of lean muscle tissue (weight-lifting) to a significant extent, which will increase your basal metabolic rate. I exercise five to six hours a week, about half resistance based, and I’ve found that I maintain my goal weight within a fairly tight range, without having to specifically count calories.
After your “diet,” and by that I also mean your daily energy expenditure habits, becomes ingrained (your new normal), you will be able to do the same.
Your diet is temporary only in the sense that it lasts as long as it takes for you to follow it naturally, without having to count and keep track on a daily basis; and if you vary by more than 5% (like the Holidays), then you start keeping track again.
