High Ketosis, Low Ketosis; Does it matter?

There are various degrees of ketosis depending on your needs. According to the chart below a Glucose:Ketone Index (GKI) below 3 is “Therapeutic ketosis” that the medical profession uses to treat epilepsy and cancer. A range between 3 and 6 would be “Moderate/functional ketosis” and desirable for obesity, type 2 diabetes and insulin resistance. Lower on the index, between 6 and 9, is “low ketosis” and used for maintenance, optimal health and weight loss. Any thing above 9 there is no ketosis.

From Wikipedia we learn that “Ketosis is a metabolic state in which some of the body’s energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides most of the energy.

Ketosis is a nutritional process characterized by serum concentrations of ketone bodies over 0.5 m/mol, with low and stable levels of insulin and blood glucose. It is almost always generalized with hyperketonemia,

Ketones: From Toxic to Therapeutic to Ergogenic

As an athlete I always thought of myself as healthy. I followed what the “experts” suggested was my best diet for an endurance athlete;

  • High carbohydrates
  • Low Fat

Late last year and in January of this year I took a long hard look at my health because;

  • I could not lose the excess body fat I gained and carried over the last three years
  • I wasn’t sleeping well
  • I wasn’t getting the athletic performance gains that I was promised if I followed a certain workout protocol

It wasn’t until I finally took to heart something I believe in:

If I always do what I’ve always done, I’ll always get what I always got.

I finally had to look to change everything I was doing because clearly it wasn’t working. I didn’t want to go insane believing that if I did the same things I would get a different result.

This is when I discovered KETONES and a LOW-CARB DIET.

May the Force Be With You! It’s where Ketosis comes from!

What I’d been told about carbohydrates from all the endurance sports coaches and nutrition experts turned out to really suck and now with this information I realize that it helped me underperform for the past umpteen years.

Well perhaps it may have worked in the past. I started racing the Ironman triathlon at age 50. From then to age 58 I maintained a decent race weight. Then in 2015 things changed rapidly for me. I gained weight even though I was doing everything the same. While training fulltime for the Hawaii Ironman World Championship I put in weeks of 20+ hours of training and I could not release 8-10 lbs around my mid section. I was also starting to have more inflammation and my performance decreased as well.

After some soul searching and asking the right questions, I switched to a high-fat low-carb diet and my health and endurance performance as an Ironman triathlete is returning.

Below is an article that says it better than I ever could. I’ll share my take at the end.
