  • ●On a fat-loss diet, measure your portion. 2 halves (8 g) already adds 52 kcal, and it's easy to eat more than you meant to.
  • ●It's low in protein (1.2 g in 2 halves (8 g)), so if you're building muscle, pair it with dal, paneer, curd, eggs or chicken.
  • ●It's high in fibre (6.7 g per 100 g), which helps digestion, fullness and steadier blood sugar.

To burn it off: 2 halves (8 g) (52 kcal) takes about 10 min of brisk walking or 5 min of running for a 70 kg adult.
