Lentils

A 198 g bowl of cooked lentils is 230 calories against the cooked record and 713 against the dry one, the record most trackers default to first.

Why this page exists

A cup of cooked lentils weighs 198 g. Log that bowl against the cooked record and it comes to 230 calories. Log the identical 198 g against the dry record instead, the one that tends to be the default because dry lentils are what people search for, and the same bowl reads as 713 calories. Nothing about the lentils changed between those two numbers. The record did.

The two states are not close approximations of each other. Dry lentils run 360 calories and 23.6 g of protein per 100 g. Boil them and the same 100 g of finished food carries 116 calories and 9 g of protein, because water has replaced most of the mass. Divide one figure by the other and the ratio lands at 3.1, close to what a home cook means by lentils tripling in the pot. A scale reading taken before cooking has to be converted, not just relabeled, before a tracker can do anything useful with it.

Everything below scales from the two USDA records on this page, dry and cooked. The serving control changes the amount, the variant selector changes which state you're logging, and the gap between them is the entire reason this page exists.

Logging lentils without guessing

Decide at which point you're weighing, and match the record to it. Weigh the lentils before they touch water and log the dry record. Weigh them after boiling and log the cooked record. What breaks a log is switching mid-recipe: a scoop weighed out of the dry bag, then an hour later the cooked result weighed again and logged against whichever record happened to still be selected. Pick one weighing point per meal and hold it there.

Weighing dry costs you the fiber number. The dry record reports no fiber and no sugar at all. The USDA never measured either on the raw dry sample, so the table marks both unavailable instead of showing a zero that isn't true. The cooked record does report them, 7.9 g of fiber and 1.8 g of sugar per 100 g. If fiber is a number worth tracking, weigh the lentils after cooking and log against the cooked record. Dry weight logged against the dry record will always show fiber as a dash, even though the food on the plate had plenty of it.

No soak, 20 minutes, and that changes which habit is easier. Lentils skip the overnight soak beans need. Rinsed dry lentils go straight into simmering water and are tender in about 20 minutes. That short a cook time makes weighing the dry portion before the pot the simpler habit for a lot of people: measure 100 g dry, cook the batch, eat all of it, and log 100 g against the dry record instead of fishing the finished lentils back onto a scale. The tradeoff is the fiber and sugar gap above. Pick the record that matches what you actually weighed.

Salt is not in either record. Both records measure lentils without added salt, dry as harvested and cooked as boiled. The dry record's sodium is 0 mg per 100 g and the cooked record's is barely higher. Whatever sodium lands in the finished bowl came from the stock, the salt you added, or the canned tomatoes stirred in at the end, and none of that is counted in the lentil figure. Log the salt and stock as their own entries rather than assuming the lentil record covers them. The high-protein soup puts that principle to work directly: its 50 g of dry lentils contribute close to nothing to the pot's 144 mg of sodium per serving, which leaves room to salt at the table instead of inheriting a fixed load.

Where lentils fit, and where they don't

Protein and fiber in the same food, at a low calorie cost. 116 calories buys 9 g of protein and 7.9 g of fiber in the cooked record, a combination rice and potatoes don't offer at the same price. Rice carries the carbohydrate without matching fiber or protein. Potatoes carry fiber without matching protein. That pairing is why lentils show up on both the fiber-focused and protein-focused sides of a grocery list rather than just one.

A gentler carb around training. Rice and lentils carry similar carbohydrate per serving, but the protein and fiber sitting alongside the carbohydrate in the cooked lentil record slow how fast it shows up as blood glucose. Legumes are the most consistent low-glycemic-index carbohydrate category in the food supply, which makes a cooked lentil bowl a reasonable stand-in for rice on a day when a slower rise matters more than convenience. On a day when convenience wins, rice still cooks in about the same time with less prep.

Fiber load and hard efforts don't mix. One cup cooked carries 15.6 g of fiber. That's a genuine win most days and a liability an hour before intervals, when a gut full of fiber is competing with hard breathing for blood flow. Save the full bowl for after training. Before training, rice or another lower-fiber carb is the safer choice.

Pair with rice or bread for the amino acid profile. Lentils run lysine-rich and short on methionine. Rice and other grains run the opposite way. Combining the two in one meal covers what either falls short on alone, the same logic behind rice and lentils or lentils and bread showing up in most cuisines that lean on legumes. A bowl of lentils on its own is still a real source of protein. Next to rice, it's a more complete one.

Buy dry, and let the pantry life make the case. Dry lentils store for a year or more in a sealed container and cost a fraction of the canned or refrigerated cooked versions. Combined with the 20-minute cook time and no soak, that makes a dry-weight batch the cheapest way to keep a protein-and-fiber carb on hand. Weigh the dry portion once, log 100 g of dry lentils against the dry record's 360 calories and 23.6 g of protein, and treat what comes out of the pot as pre-portioned rather than something to re-weigh.

    100 g of dry lentils weighed straight from the bag before they touch water. Cook the whole batch, portion it into containers, and log 100 g against this dry-weight figure rather than re-weighing the cooked mass later. Cheap, shelf-stable, and the math stays simple.

    A standard 1 cup serving of cooked lentils. 15.6 g of fiber and 17.9 g of protein for 230 calories is a hard combination to beat from a single ingredient. This only works if you weigh the lentils after cooking and log against this record, not the dry one.

  • A gentler carb than rice around training

    150 g cooked carries 30.2 g of carbohydrate for 174 calories, with the protein and fiber that come from the same record slowing how fast that carbohydrate shows up as blood glucose. Reach for this over rice on a day when a slower rise matters more than convenience.

    35 g of dry lentils, the USDA reference amount, carries essentially no sodium on its own. Everything salty in the finished soup comes from the stock or the salt you add, and this record won't hide that from you.

Methodology

Where the numbers come from

Every figure on this page is scaled from a per-100 g value in a USDA record by one shared function, so the numbers here and the numbers on a meal page that uses this ingredient cannot disagree. Values are rounded once, at the point of display.

Unavailable values

A nutrient a record does not measure is shown as unavailable and never as zero. Across the 405 records in this dataset, 165 report no fiber and 228 report no sugar, so the distinction is not a rare edge case. A zero on this page means the analysis measured zero.

Source coverage

Every claim on this page resolves to one of the records listed here. This family has no open source gaps.
