World-leading sports nutritionist James Collins shapes the diets of Olympic athletes and Premiership footballers, so they are on peak form when it counts.

After a decade of working with the likes of Frank Lampard and Alexis Sánchez, now he's distilling his elite sports success into simple food principles that any of us can follow to feel at our best in our daily lives.

Peak performance is all about energy and how to eat right for your body and your routine.

By following the Energy Secret plan, you will learn how to fuel your body for your life, power through the 4pm slump and resist the junk foods that drag you down.

Instead you will naturally choose foods that will leave you bursting with energy for work and play.

You'll feel more productive and flourish under pressure.

You'll sleep well, lose unwanted weight and never (or rarely) get ill again.
