Meet the dad-of-two who has lost over 50kg on a diet of grapefruit, chips and his own urine.

Dave Murphy says the unusual beverage choice has seen him go from 20st to 12st, cured his asthma and is the key behind his youthful good looks. Dave also believes that the practice of urine therapy could be a means of solving the world food shortage – and slashing people’s grocery bills.

For the last six years, Dave, 54 from Basildon, Essex has been drinking his own wee – and even bathing in it. Most days, Dave survives on little else besides one grapefruit and two glasses of his own urine. His only indulgence is a small portion of chips from his local chippy three times per week. In fact for thirty days in 2012, Dave subsisted on nothing else but his own urine.

Dave also uses his urine to moisturize his face. He maintains that wee is the ultimate anti- ageing product. Dave began his unique practice in May 2011 after he hesitantly attended a talk about urine therapy. At the time, Dave was clinically overweight at a whopping 20-stone and he suffered from poor health, including life-long asthma.
