The answer is yes. Stop engorging carbohydrates, go fast. There are quite a number of pieces I published that I write about how fasting helps you.
But I rather refer to historical figures today.
Start fasting that will solve lots of the Covid/Spike issues.
A 5 day water fast wiped out the fatigue I had for 3 months after Covid.
Intermittent fast, 14-18 hours a day for several years now. I did a 20 mile cycle a few weeks ago and realised I hadn't eaten til I got back, it works.
