A man shed a staggering 15st - more than half his bodyweight - by eating a carnivore diet consisting of just meat and eggs.

Isaiah Caldwell, 28, tipped the scales at 31 stone at his heaviest.

But after being told his weight might be causing fertility issues he decided to change his lifestyle - and now weighs 16 stone.

Tech salesman Isaiah, from St Louis, Missouri, US, lost the weight by following the carnivore diet.
