How much saturated fat should a woman eat a day?
The same line as everyone, under 10% of your calories. For a woman eating 1,600 calories that’s about 18 g of saturated fat a day, at 1,800 it’s 20 g, and at 2,000 about 22 g. The tool below works out yours.
It’s easy to take the label’s 20 g as your limit. It’s the same Daily Value for everyone, though, and the US guidelines put most adult women’s calorie needs at 1,600 to 2,400 a day. At 1,600 calories, 20 g is 11% of your day, a little over the line. Your own line can be smaller than the label’s.
What we’d do: work out your own number once and keep that in your head instead of the label’s. Across the guidelines’ 1,600 to 2,400 calories, that’s 18 to 27 g, and one tablespoon of butter is between a quarter and two fifths of it.
Your line by calories
| Calories a day | Saturated fat line | A tablespoon of butter (7.2 g) is |
|---|---|---|
| 1,400 | 16 g | 46% |
| 1,600 | 18 g | 40% |
| 1,800 | 20 g | 36% |
| 2,000 | 22 g | 32% |
| 2,200 | 24 g | 29% |
| 2,400 | 27 g | 27% |
The line is calories × 0.10 ÷ 9, since fat has 9 calories a gram. These are the US guideline’s lines. The Gyroscope app personalizes yours.
Where most women are
The 2020 to 2025 US guidelines found the average woman eating about 210 calories of saturated fat a day, which is about 23 g. That’s over the line for a woman on 2,000 calories or less. More than 70% of adults are over.
The biggest single source is usually in plain sight. An ounce of cheddar has 6.0 g, a cup of whole milk 5.1 g, and a butter croissant 6.6 g, so one croissant is about a third of a 1,600 calorie day’s line. The scorer on the home page splits a whole day for you, and the quiz finds the one swap.
The other fats women need
Two fats are essential, since your body can’t make them, and the US sets a floor for both. Women 19 to 50 need about 12 g a day of linoleic acid and women 51 and up about 11 g. Every adult woman needs about 1.1 g a day of alpha-linolenic acid, the plant omega-3, which is about two teaspoons of ground flaxseed or half an ounce of walnuts (about 7 halves).
If you’re pregnant or breastfeeding, the fish advice changes. The FDA suggests 8 to 12 ounces of seafood a week from its lower-mercury Best Choices list, such as salmon, sardines and trout, and the 2026 guidelines name the same three fish. Your midwife or doctor can help you fit that in.
