He started with a 16-hour daily fast and gradually increased it to 24 hours. He also started exercising while fasting, mainly doing cardio and weightlifting. He found that he had more energy during his workouts and could push himself harder.
James also changed his diet to whole foods and cut out processed junk food. He drank plenty of water throughout the day to stay hydrated, and he took electrolyte supplements to ensure he wasn’t depleting his body’s stores.
The results were astounding. James lost almost 50 pounds over the course of a few months, and he was able to maintain his weight loss for over a year and counting. He credits his success to his fasting schedule and exercise regimen, as well as the support and accountability of his weight loss coach.
In conclusion, yes, you can exercise while fasting, and in fact, it may even be beneficial for weight loss and improving overall fitness. Training in the fasted state can activate your body’s energy stores and increase growth hormone production, leading to faster recovery from workouts. However, listening to your body and adjusting your workouts is essential, especially if you feel dizzy or lightheaded.
Suppose you’re considering incorporating fasting and exercise into your weight loss journey. In that case, it may be helpful to seek the guidance of a weight loss coach or medical professional who can provide personalized advice and support. And, as James’s story shows, with the right tools and mindset, sustainable weight loss is possible.

Summary of Transcript:
The video discusses whether exercising is possible while fasting, and the answer is yes since the body can store calories. Body fat stores energy, so while fasting, the body can burn stored energy or glucose in the blood for exercise. Training in the fasted state, or just before breaking a fast, is beneficial to activate systems that release growth hormones and increase nervous system response. The video also discusses a weight loss success story of someone who followed guidance from a coach.
