I have followed Dr. Berg’s recommendations for years and it goes something like this:
Over-exercising is just going to keep cortisol levels high and no body fat ever gets burned even with low insulin or a ketogenic diet, then their is the estrogen molecule which is the least of the big 3 fat blocking hormones!
The only way to defeat that cortisol and leptin resistance (if T3 is high?), that I know of is HIIT.
I like to use an elliptical cross training machine for HIIT to defeat both cortisol and leptin resistance! I bought my own elliptical for $2800 because it really does work for me!
Short burst high intensity interval exercising e.g. 5 sets for 5 or 10 minutes a day or every other day what ever you feel you can handle? (DO NOT EXERCISE ANY MORE THAN THAT A DAY IF YOU WANT TO BURN BODY FAT?)
Exercising for hours on end will just defeat your goal of burning body fat unless your into building bigger muscles?
Experiment and see what works for you?
Also wanted to mention be mindful of your internal circadian clock; always exercise after 5:00 PM so when you go to sleep at night your HGH will be a lot higher from exercising and burning the body fat while you sleep and then starts to decline throughout the day and won’t be blocked by high cortisol levels if you try working out in the morning or afternoon?
