When Dr John Hart turned 50 he was overweight, with constant fatigue and brain fog, a fading memory, low mood and no libido or enthusiasm. He didn’t like the answer of what the future held. So he started researching anti-ageing and functional medicine, applying what he learnt, and saw incredible changes in his body composition, memory and attention and overall vitality and health.

Dr John is the founder of the Hart Clinic and author of The Brain Book. You can find out more about him at www.drjohnhart.com
