the best fruit for you

(343kJ per medium grapefruit)

Grapefruit diets may have gone out of style with leg warmers and leotards, but these orbs are still one of your biggest diet allies: "They're low in sugar and high in fibre, plus research shows they improve insulin resistance, meaning they make you feel fuller," says dietician David Grotto, author of 101 Optimal Life Foods. In a study published in the Journal of Medicinal Food, obese adults who ate half a grapefruit before each of their three daily meals lost 1.4kg more over the course of 12 weeks than those who skipped the grapefruit appetiser.

Squeeze More In Citrus is a great complement to soy sauce and other Asian flavours. Add grapefruit segments to a stir-fry once everything else is cooked, then stir gently and heat until just warmed.
