Health, Fitness, BMI, and AI…Are They Connected?

Health and Fitness are poorly defined terms and can only really make sense when you apply your own personal definition. With that said there are general definitions that most people will accept as having at least something to do with both health and fitness.

Health seems to have something to do with reducing risk of premature death and disease, namely having favorable blood markers for disease such as total cholesterol, HDL, LDL, HDL/LDL ratio, Triglycerides, glucose, insulin, blood pressure and heart rate.

Beyond that, reduced stress and how you feel in general are probably the most important indicators of health.

Fitness on the other hand seems to refer to movement and capacity to be active.

So far there isn’t one measurement that indicates health AND fitness, until now.

I think the Adonis Index ratio might the one measurement that indicates both health and fitness.

In recent years height to waist ratio has gained favor over BMI as a better indicator of health and disease risk for lifestyle disorders such as cardiovascular disease, obesity, and diabetes.

But height to waist ratio doesn’t say much about fitness. I think the addition of the shoulder measurement and thus the Adonis Index ratio is a more complete measurement of both health and fitness.

Having and healthy and fit body is synonymous with having a body that other people will admire.

In todays podcast we discuss:

1. What health means and how we measure it

2. What fitness means and how we measure it

3. What the look of a healthy body is

4. BMI vs Height to Waist Ratio vs Adonis Index Ratio as markers of health and fitness

5. A personal health perspective vs a global health perspective

6. What to do when you’ve made a big time change in your health and fitness

p.s. Here is the awesome thread in the forum that we talk about in the podcast (there are multiple pages, click through to the 2nd or 3rd page for the cool before and after’s).

Weight Loss Research Explained

In last weeks podcast I interviewed a weight loss researcher who is beginning to study body fat regulation. We discussed some of the theories that he and his colleagues would be trying to explore during their research.

This brought up many issues about the way weight loss research is done and if weight loss research itself can be of any real value to free living people.

Some of you seemed to find last weeks podcast a contradiction to what you’re used to hearing from me.

Although I didn’t agree with much of what Stephan had to say I wanted to give him a fair chance to explain his theories. After all I approached him for an interview, it wouldn’t be fair if I just fought with him on each point I disagreed with (and there were many).

This weeks podcast is an explanation of my views on how the process of studying weight loss is itself the confounding variable that renders most of the research virtually useless.

I will also discuss research bias and why you must take these kinds of research claims and theories with a grain of salt.

Finally the true weight loss experiment is you and the rest of us who are doing it for real on our own without being in an artificial research setting. In essence we are the only true weight loss research study worth paying attention to.

Body Fat Regulation, Can We Change it?

The regulation of body fat stores is a complex interplay of many hormones, chemical messengers and systems with your body. It’s also big business for the food and supplement industry. It is also a growing area of research as we try to get a better understanding of what exactly is going on.

In this podcast I interview Stephan Guyenet, his area of research is body fat regulation.

We discuss the possible mechanism for body fat regulation and why we are seeing the overweight and obesity issues that are becoming prevalent in todays society.
