I'm unsure if that is a good combination fasting and heavy exercise especially road cycling.
Firstly I didn't want to hijack this thread but as a legit question has been asked I figured I'd answer it.
Hi
@JohnEGreen
On this link
Dr Mosely shows his torso via an MRI
This shows what "That white stuff is all fat" said Mosely, we know that visceral fat is what actually causes T2DM. In the above clip Mosely explains that he's a Toffee thin on the outside with fats around his organs on the inside. If you watch the entire video Mosely was a relatively thin diabetic (BMI 26s) to start in the first place. When tested in the US though he had 30% abdominal fat.
Over here
https://intensivedietarymanagement.com/fasting-and-exercise-fasting-23/ Dr Jason Fung explains
" For example,
this study looked at muscle fibres both before and after training in the fasted state. This means that you fast for a certain period of time, usually around 24 hours and then do your endurance or other training. The combination of low insulin and high adrenalin levels created by the fasted state stimulates adipose tissue lipolysis (breakdown of fat) and peripheral fat oxidation (burning of fat for energy). " I think we can agree that we as T2DM's need to break down our visceral fats..
Fung goes on and in summation gives his best ideas..
"So, what’s my best advice on physical exertion and fasting? Don’t worry about it. Do everything you normally do during fasting. If you normally exercise, or even if you don’t, you can still do it during fasting. Whether you fast for 24 hours or 24 days, you can still exercise." (If its good enough for Lebron its probably okay for a weeks fasting for LBB)
A good deal of current knowledge of reversals of T2DM stem from bariatric surgeries. Professor Roy Taylor 's work tries to mimic surgery with his 2011 studies on 800 kcals/day for 8 weeks for diabetic patients.
Here Dr Jason Fung
https://intensivedietarymanagement.com/fasting-cures-diabetes-t2d-4/
shows that within one week of post bariatric surgery blood sugars are normalized
even before the benefits of massive weight loss is enjoyed. This is what we T2DM's could be doing, aggressively mimicking a surgery we won't or can't do..
I hope my thinking stands up to peer reviews.. If I've said anything contentious in voicing ideas here please don't start a flame war.. PM me and I'll modify my post..
