In the context of human history, our transformation into coach potatoes happened in the blink of an eye. Only 100 years ago, most people relied on manual work to make their living.

Today, things are different. Many of us live our lives in front of a screen. Online shopping and remote work mean some of us don’t need to leave the house at all. So how bad is this for us?

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.

In today’s episode, Jonathan speaks to a Human Physiologist to learn about the interactions between diet and exercise and their impact on human health:

Dr. Javier Gonzalez is an associate professor of Human Physiology at the University of Bath and also a technical advisor to the athletes in the INEOS Tour de France cycling team.
