Flaxseed fits a weight-loss plan as a daily spoon. A serving (1 tablespoon, about 10 g) gives 44 kcal with 2.6 g of fibre and 1.9 g of protein. It does not burn fat; it adds fibre that helps meals keep you full, and it is easy to stir into curd, dal or roti dough.

The verdict on flaxseed

Spoon-sized food

Use it by the spoon or the small handful: 400 kcal or more in every 100 g.

  • 4.2 g of protein for every 100 kcal.
  • One serving gives 1.9 g of the roughly 58 g of protein a day ICMR-NIN's RDA sets for a 70 kg adult.
  • 2.6 g of fibre in a serving.

How flaxseed fits a plan that loses fat and keeps muscle

IFCT 2017 lists linseeds at 26.2 g of fibre per 100 g, the most fibre of any food in this guide, alongside 444 kcal. That combination is why a single spoon is the right amount: plenty of fibre, but calorie-dense if you pour it.

Ground flaxseed is easier to digest than whole seeds, which can pass through unchanged. Grind a week's worth at a time and keep it in the fridge.

Flaxseed in an Indian kitchen

Flaxseed, alsi, is best ground: whole seeds often pass through undigested. Grind a small batch in a mixer and keep it in an airtight jar in the fridge, since ground flax turns rancid at room temperature. Stir a tablespoon into atta dough, a bowl of curd, oats or a smoothie. Roasted alsi with a little salt is a Punjabi mukhwas after meals. Start with a small amount and drink water, since it adds a lot of fibre at once.

Pair it, or swap it

A spoon of ground flax in curd, a smoothie, or kneaded into roti dough adds fibre quietly. Alsi chutney with roti is a traditional way to eat it.

Worth knowing

Start with a teaspoon and drink water through the day; a lot of fibre at once can cause bloating.
