A short fasted cardio was one of the tools I used to tap into belly fat. Excessive amounts can increase stress but starting with as little as five minutes and building slowly can make great effect. If you haven’t done it before, it will be great to discuss with your physician to start any exercise regime. I also shared one of my friends who used fasted cardio with permission from her physician and supervision of her training coach. There are two articles discussing her fat loss journey which might give you some perspectives.
I also recommend this post which reflects my years of research and experience on calories versus hormones. The science is crystal clear about the hormonal effects on fat-loss while some people still count calories and miserably fail in the long term. I was one of them and learned my lessons in a hard way.
I hope these personal stories might inform you and empower you to research the topic and develop your experiments with the help of your healthcare advisors. I wish you the best in your health journey.
