Orange is the new… belly blaster?

So says new research in the British Journal of Clinical Pharmacology, which found that taking a supplement of p-synephrine — an alkaloid naturally occurring in citrus fruit — before exercise helped people torch more fat during their workouts. The effect was the equivalent of ditching about two kilos of pure fat in a year (if you work out moderately for an hour most days).

And according to the USDA, one medium-sized orange (sans peel) has 270 kilojoules, one gram of protein, 0.3 grams of fat, 16 grams of carbs, 3 grams of fibre, and 13 grams of sugar. They’ve got a solid rep as being packed with vitamin C (although there are some foods that have even more) and have a decent calcium content (about six percent of your daily value). Orange peel is also packed with cancer-fighting d-limonene. However, eating too many oranges per day can trigger acid reflux since they’re highly acidic, so limit your servings to no more than two per day if you’re concerned.

Bonus reason to slurp something tart: your body easily uses fruit sugars for energy, meaning you’ll be able to go hard at the gym.
