High intensity intervals are one of the best ways to burn fat – and keep burning it throughout the day.

Your session should last about 20 mins. Try 30 seconds of sprinting followed by 90 seconds of walking, repeated 10 times.

Then load up on omega-3-rich oily fish, such as salmon, served with salad leaves, tomatoes and raw peppers. Omega 3 foods keep you satiated and turn on fat-burning genes.
