Good job! Yes, fasting is effective.
My farming career included plenty of livestock related work, very physical. The last 16 years of it I worked various physically demanding off the farm jobs.
But quitting the farm career in 2001, then becoming a truck driver, showed me how quickly weight can be added. I nipped it in the bud by exercising at the end of the day, whether at home or a truckstop (I’m proof you don’t need a gym full of equipment to stay in shape).
We daily take some apple cider vinegar with water and juice. That stuff does work wonders.
The biggest change was a month into fasting I had my yearly physical. I have had genetically high cholesterol my entire life. Tried five different statins. My total cholesterol went from 290 to 205 from the previous year. That was after only dropping the initial 10-15 pounds.
