“Light” or “lite” has two doors, and which applies depends on your product’s fat profile: if 50% or more of its calories come from fat, cut fat by at least 50% per Reference Amount Customarily Consumed (RACC) versus a named reference food; below 50%, qualify by cutting calories by at least one-third OR fat by at least 50% (21 CFR 101.56(b)). “Light in sodium” is a separate, sodium-only version requiring at least a 50% sodium cut. Every version is a relative claim needing a reference food and a comparative statement naming it and the percentage reduced. The trap: skipping the “which door applies” step, or using “light” for texture/color without the disclosure that keeps it from reading as a calorie claim.

| Threshold | ≥50% cal from fat: fat cut ≥50%. Else: cal cut ≥1/3 or fat cut ≥50%. Sodium: cut ≥50% |
| Claim type | relative |

| Disclosure statement | Not applicable |
| Wordings FDA allows | Light, Lite, Light in sodium, Lightly salted |
What the rule says
21 CFR 101.56(b) states: “‘Light’ or ‘lite’ may be used if the food derives 50 percent or more of its calories from fat and the fat is reduced by 50 percent or more, or the food derives less than 50 percent of its calories from fat and the calories are reduced by one third or the fat is reduced by 50 percent or more per reference amount customarily consumed.” Paragraph (b)(4) bars the claim where there’s nothing left to lighten: “A ‘light’ claim may not be made on a food for which the reference food meets the definition of ‘low fat’ and ‘low calorie.’”
Sodium has its own branch. “Light in sodium” requires at least a 50% sodium reduction per RACC versus the reference food. “Lightly salted” is a related but distinct, lower-bar term: at least 50% less sodium added than is normally added to the reference food; if the product still isn’t “low sodium,” the label must carry “not a low sodium food” next to the Nutrition Facts panel.
“Light” can also describe a physical attribute under 101.56(e): the attribute (e.g., “color” or “texture”) must appear “in the same style, color, and at least one-half the type size as the word ‘light’ and in immediate proximity thereto.” Separately, 101.56(f) exempts uses tied by long common usage to specific foods (light brown sugar, light corn syrup) from being nutrient content claims at all.
Every branch is still a relative claim under 21 CFR 101.13(j): the reference food must be an appropriate one, and 101.13(j)(2) requires the label state its identity and the percentage or fraction reduced, in immediate proximity to the claim.
The numbers
| Fat share of calories | Path to “light” |
|---|---|
| ≥50% from fat | Fat reduced ≥50% per RACC vs. reference food |
| <50% from fat | Calories reduced ≥1/3, or fat reduced ≥50%, per RACC |
| Sodium | “Light in sodium”: sodium reduced ≥50% per RACC |
| Sodium, lower bar | “Lightly salted”: ≥50% less sodium added than normally added; “not a low sodium food” disclosure if still not “low sodium” |
Find the fat share with: (grams of fat × 9 calories/gram) ÷ total calories. At 50% or higher, only the fat-reduction path is open; below that, either path works.
The comparative statement under 101.13(j)(2) needs the reference food’s identity and the percentage or fraction reduced (“1/3 fewer calories than [reference food],” or “fat reduced 50% from [reference food]”), plus quantitative per-serving comparisons near the claim.
Rounding under 21 CFR 101.9(c)(1) governs what prints on each panel, but the reduction math runs on unrounded values. If your reformulation pushes fat, saturated fat, cholesterol, or sodium over the disqualifying levels in 21 CFR 101.13(h) (13 g / 4 g / 60 mg / 480 mg per RACC), that disclosure applies independently.
On the label
Take a regular ranch dressing at 130 calories and 14 g fat per RACC (2 tbsp, per 21 CFR 101.12’s table). Fat is roughly 97% of calories, over the 50% line, so only the fat-reduction door applies. A reformulated version at 6 g fat (57% cut) qualifies: “Light Ranch Dressing: 57% less fat than our Regular Ranch Dressing (14 g reduced to 6 g fat per serving).” See our salad dressing label guide.
Now take a granola bar under the 50%-from-fat line: a reference bar at 200 calories and 6 g fat (27% from fat) per RACC. It can qualify by cutting calories a third (to 133 or fewer) or fat by half (to 3 g or fewer); only one path needs to clear. See our granola bars label guide.
For sodium, if you cut your jerky’s sodium from 600 mg to 280 mg per RACC (53%), your label could use “Light in Sodium: 53% less sodium than our Regular Beef Jerky.” See the jerky label guide.
Mistakes we see
- Skipping the fat-share test. At ≥50% of calories from fat, the calories-cut-by-a-third alternative isn’t available. Only the 50% fat cut qualifies.
- Using “light” for texture or color without the required disclosure. “Light and crispy” without “crispy” alongside “light” at half its type size, per 101.56(e), reads as an implied calorie claim.
- Confusing “light in sodium” with “lightly salted.” Different thresholds (50% sodium reduction vs. 50% less sodium added), and only “lightly salted” carries the “not a low sodium food” disclosure.
- Missing the comparative statement or reference food identity. 101.13(j)(2) requires both, next to the claim.
- Claiming on a food already both low fat and low calorie. 101.56(b)(4) bars it outright.

Light / Lite claim FAQ
What's the difference between "light" and "lite"?
None under the regulation. 21 CFR 101.56 treats them as the same claim, spelled either way, subject to the same numeric tests.
What if my product already gets most of its calories from fat?
If 50% or more of your product's calories come from fat, the only path to 'light' is cutting fat by 50% or more per RACC compared to the reference food. The one-third-fewer-calories alternative isn't available to you.
Can I call a product "light" just because it tastes or looks lighter?
Only for a genuine physical attribute (color or texture) under 21 CFR 101.56(e), and the attribute name must appear in the same style and color as 'light' and in type at least half its size, in immediate proximity to it.
What's "lightly salted"?
A sodium-specific claim requiring at least 50% less sodium than is normally added to the reference food; if the resulting product isn't also 'low sodium,' the label must carry 'not a low sodium food' next to the Nutrition Facts panel.
Does a "light" claim need a reference food and comparative statement?
Yes. Light is a relative claim under 21 CFR 101.13(j): the label has to name the reference food and state the percentage or fraction of calorie, fat, or sodium reduction in immediate proximity to the claim.
