Having an accurate way to measure your progress is important. For some background information on measuring your progress go to the article Measuring Your Progress.


The Metabolic Index (MIDx) is the best way to measure your progress while you're on my phase shift diets, or for that matter any time you want to see how you're doing as far as body composition. The MIDx takes into account all the variables that other methods can't. Not only does it address the height/weight issue but also the degree of body fat. With the MIDx you get a snap shot of your body composition and progress.


What is the MIDx and what does it measure? The MIDx is a ratio derived by considering not only weight and height but also your percentage of body fat. It uses a very easy formula for calculating. In fact, just fill in your weight in pounds, your height in inches and your bodyfat level as a percentage into the following formula and do the calculations.




Figuring Out the MIDx


Body weight in pounds divided by the height in inches squared and the results multiplied by 7,250 and the results divided by the percent body fat.


{(body weight in pounds) / (height in inches)2 * 7,250} / % body fat.


Or if you are using the Metric system:


{(body weight in kilograms) / (height in meters)2 * 10.3} / % body fat.


In my case, using pounds and inches, my MIDx is 185 / (66)2 * 7,250 divided

by 10%


(185 / 4356) * 7,250 / 10

MIDx = 30.8




Or even better just plug in your statistics into our form and get your MIDx immediately. Go ahead and plug in some maybes and see how the MIDx changes as you drop weight and body fat and get toned.


My Metabolic Index

In my case, my MIDx is 185 / (66)2 * 7,250 divided by 10%

(185 / 4356) * 7,250 / 10 MIDx = 30.8


Even though I'm heavy for my height, I have a fair amount of muscle mass and a low body fat. So rather than looking fat I look trim and muscular. When I was an elite powerlifter I varied my weight considerably going up to as much as 212 lbs and as low as 132 lbs (so I could compete in the 132 lb class, if only for a short time). At 132 lbs my bodyfat was 3%. If we plug this informaiton into the MIDx equation we come up with a value of 73.23. That number is off the charts but there's not many people in the world that would have that extreme body composition,, and not many that either would want to or be able to maintain it. The exception would be competitive bodybuilders who would be looking to having more muscle mass and lower single digits of body fat.


On a more reasonable level, let's say that I go into a cutting phase of one of my phase shift diets, for example the Metabolic Diet or the Anabolic Diet (the Anabolic Solution for Bodybuilders includes the updated version of my Anabolic Diet), and get down to 175 lbs and 8% bodyfat. My MIDx would then be 36. The increase in the MIDx shows that at 175 lbs. and 8 % bodyfat I'm carrying less fat in proportion to my muscle mass than at 185 lbs. and 10% body fat. This shows that I'm making progress as far as improving my body composition.


Once you've established your baseline MIDx it's easy to objectively see if you're making progress...

The important thing about the MIDx is that it will give you a starting point and from there an indication of how you're progressing every step of the way. Once you've established your baseline MIDx it's easy to objectively see if you're making progress, if you're losing body fat but not at the expense of important muscle mass. If the MIDx is going up, even minimally, you're making progress.


The higher the Metabolic Index, up to a point, the better your improvement and the closer you are to your goals. The lower the Metabolic Index is, the more room for improvement there is and a determination of just how much more you have to go to reach your goals.


The ideal for the average woman is different than the ideal for average man. For women the ideal is around 13 to 20 while for men it's between 22 to 32. In reality the final point doesn't really matter since it's the improvement that counts. As long as the index keeps going up then there is some improvement being made. Once the index gets above 18 for women and 32 for men you've looking at muscle mass and body fat levels that are too extreme for most of us but not to those who aspire to bodybuilding and competitive fitness standards.


In reality, the MIDx is an indicator that when you're losing weight you're close to maintaining or even increasing lean body mass as you lose body fat. In fact, the more lean body mass you have and the less fat the better the index. If someone loses even a lot of weight but loses too much lean body mass the index won't improve all that much. What that means is that even though the person has lost weight they look very flabby and therefore lost the weight by sacrificing muscle mass. This is exactly the opposite of what most people want. They want to lose weight but they also want to look slim and trim.


Now that you've got something to accurately measure your progress, let's get at it by following one of my phase shift diets (the prototype which is the Metabolic Diet but also included the Anabolic Diet, Radical Diet, and the Anabolic Solutions for Bodybuilders and Powerlifters) and working out. And for those who want faster results, taking some of the my MD+ line of supplements that I especially formulated for use with my phase shift diets.
