Peanuts fit a weight-loss plan as a measured handful. A serving (30 g, a small handful) gives 156 kcal, 7.1 g of protein and 11.9 g of fat, per IFCT 2017. They are filling and cheap, and they are calorie-dense: the handful is the whole point.

The verdict on peanuts

Spoon-sized food

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

  • 4.5 g of protein for every 100 kcal.
  • One serving gives 7.1 g of the roughly 58 g of protein a day ICMR-NIN's RDA sets for a 70 kg adult.
  • 3.1 g of fibre in a serving.

How peanuts fits a plan that loses fat and keeps muscle

IFCT 2017 lists groundnut at 520 kcal and 23.6 g of protein per 100 g, the most protein of any nut or seed in this guide. Most of the calories still come from fat, so peanuts work as a snack or a topping, not as a main protein.

Portion is everything. A small handful in poha, a spoon of crushed peanuts in a salad, or a measured bowl as an evening snack all fit a calorie deficit. A whole packet in front of the TV can add a meal's worth of calories.

Peanuts in an Indian kitchen

Dry-roasted peanuts in their skins, from a street vendor or roasted at home in a kadhai, are a better snack than salted, fried or masala-coated ones. Count a small handful into your palm rather than eating from the packet. Crushed peanuts add crunch and protein to poha, sabudana khichdi and a kosambari salad. Peanut chutney goes with idli and dosa. Peanut butter with no added sugar is fine in a teaspoon; chikki is mostly jaggery.

Pair it, or swap it

Boiled peanuts with onion, tomato and lemon are lighter per bowl than roasted ones because they hold water. A teaspoon of peanut butter on apple slices makes a balanced snack.

Worth knowing

Masala peanuts, fried and salted, and chikki with jaggery are different snacks. Peanut butter often has added sugar and oil; choose one that lists only peanuts.
