Your One-Day Fat Blast

Mix it up

By Susan Hall

7 a.m.

Interval training (alternating moderate exercise with bursts of intensity) increases fat burn by 36 percent. Try this 30-minute routine: Walk at a moderate pace 1 minute, walk briskly 1 minute, run at a moderate pace 1 minute, then sprint 1 minute; finish with 30 seconds each of lunges and squats. Repeat 6 times.

Eat your oatmeal

9 a.m.

Enjoy 1 cup of cooked oatmeal topped with 2 tablespoons each of walnuts and dried tart cherries, and you'll get three flab-blasting powerhouses—metabolism-revving Resistant Starch (in oatmeal), which can help boost your body's fat-burning ability by 25%; slimming omega-3s (in walnuts); and belly-fat-targeting anthocyanins (in tart cherries).

Hit the lobby bathroom

9:30 a.m.

When nature calls at the office, take the stairs to a loo that's not on your floor. Walk a bit afterward, and you'll burn 40 calories total in 10 minutes.

Curl and chat

10 a.m.

Muscle torches calories, so build more by keeping a set of 5- to 10-pound dumbbells under your desk and doing biceps curls while you're on the phone. You'll burn nearly 20 calories in 5 minutes.
