The Krispy Kreme milkshake as fattening as a Sunday roast with 612 calories

A food chain has unveiled a sugar-laden milkshake with as many calories as a typical Sunday roast.

Nutritionists branded the concoction from Krispy Kreme a ‘calorie explosion’.

The strawberry and cream version contains 612 calories – more than a quarter of a woman’s daily allowance and almost as much as a 650-calorie roast chicken dinner.
