How to lose almost 1lb in 12 hours. Simply burn duck fat overnight as you sleep.

Fry off and then gently oven roast duck breasts and use the fat that comes off to stir fry vegetables. I had 2 breasts and kale with pancetta. Enjoy for dinner then burn it, and some extra fat off while you sleep!

18.30 prior to duck: 12 st 8.3 lbs.

6.30am the following morning: 12st 7.6lbs.

No exercise required!
