Quick takeaways

Exercise is crucial for health, improving heart health, muscular-skeletal health, fat tissue, and brain health, with recommended levels of moderate-intensity or vigorous-intensity exercise along with strength training.

Diet plays a more significant role in weight loss than exercise, as it is easier to consume calories than burn them through exercise, but exercise can help control appetite, improve body composition, and complement dietary efforts.

Exercising in a fasted state can lead to increased fat burning, improved glucose control, and enhanced insulin sensitivity, but the benefits may vary depending on individual goals and preferences, and a mix of fasted and fed exercise can be suitable.

The answer is now clear: Low levels of physical activity lead to an increased risk of disease and a lower quality of life in older age. However, when we come to the question of what sort of exercise you should be doing, how often, and how much it contributes to weight loss, the answers might surprise you.
