Cereal, O's, honey nut calories: 154 per 1 cup (40 g)
This exact USDA record reports 154 calories for 1 cup (40 g). That answer belongs to this description and weight; it is not a universal value for every meal that shares the name.

The editorial read
The useful answer has a weight, a composition, and an identity
Portion: the cited record reports about 154 calories for 1 cup at 40 grams. On a fixed-weight basis, the same record contains 385 calories per 100 grams. The first number answers a portion question; the second answers a concentration question.
Composition: that source amount also reports 3.4 g protein, 3 g fiber, and 232 mg sodium. Read those values together: a calorie total by itself cannot describe the nutrient profile.
Identity: the largest listed formulation input is cereals, oats, regular and quick, not fortified, dry, representing 65.5% of the record’s listed input weight. The record contains 11 source-input rows in all. These are provenance for a standardized calculation, not a recipe for your plate.
The source calls its underlying survey portion “Quantity not specified,” but it separately lists 1 cup at the identical weight. We use the familiar household label here without changing the source calculation.
The household measures attached to this record span roughly 116–154 calories across the listed portions. That is a set of scaled examples—not a confidence interval, a recommendation, or a claim about the full universe of recipes.
Calculated from the smallest and largest usable household measures listed by USDA for this exact FNDDS record; not a confidence interval.
Record-specific decision brief
What the numbers say—and what choice still belongs to you
This analysis belongs to USDA FDC 2708464: “Cereal, O's, honey nut.” It separates gram-weight arithmetic, corpus context, label signals, and record selection so one number does not have to answer four different questions.
01 · Portion arithmetic
Three weights, one fixed composition
For FDC 2708464, each row multiplies the published per-100-gram values by its stated weight. “1 prepackaged single serving” through “125% of the reference weight” are weight scenarios: named measures come from USDA, while percentage labels are transparent arithmetic.
| Scenario | Weight | Energy | Protein | Fiber | Sodium |
|---|---|---|---|---|---|
| 1 prepackaged single servingUSDA-listed household measure | 30 g | 116 kcal | 2.6 g | 2.3 g | 174 mg |
| 1 cupUSDA-listed household measure | 40 g | 154 kcal | 3.4 g | 3 g | 232 mg |
| 125% of the reference weightArithmetic scenario from the reference weight | 50 g | 193 kcal | 4.3 g | 3.8 g | 290 mg |
02 · Fixed-weight context
Where 100 grams sits inside Ready-to-eat cereal, higher sugar (>21.2g/100g)
The comparison set contains 20 exact records in the Ready-to-eat cereal, higher sugar (>21.2g/100g) USDA category. Here, “middle half” describes FDC 2708464’s energy position in that corpus—not nutritional quality, desirability, or a health rating.

03 · FDA label lens
The strongest strength-side and tradeoff-side signals
At FDC 2708464’s 40 g reference weight, the largest strength-side percentage among the nutrients evaluated here is Iron; the larger tradeoff-side percentage is Sodium. Percentages use FDA label Daily Values, whose general “high” guide begins at 20% Daily Value. This is not an overall score or a personalized target.
Strength-side signals

04 · Highest-impact checks
The three levers most worth resolving first
For “Cereal, O's, honey nut,” the first-pass checks follow the evidence actually published: its named weights, the FDC 2708446 alternative, and its source-formulation identity.
- 01
Listed portion span: 1 prepackaged single serving to 1 cup
USDA assigns those measures 30 g and 40 g. At this record’s fixed composition, scaled energy moves from 116 kcal to 154 kcal.
- 02
Source identity: FDC 2708464 versus 2708446
The closest published neighbor currently carries the same nutrient, portion, and source-input evidence. The FDC IDs still identify separate source records, so the exact citation remains the deciding field.
- 03
Formulation anchor: Cereals, oats, regular and quick, not fortified, dry
The source formulation has 11 input rows; Cereals, oats, regular and quick, not fortified, dry supplies 65.5% of listed input weight. Those are standardized formulation inputs, not final plated percentages.
05 · Exact-record choice
Select by literal evidence, not the shortest name
The published nutrient, portion, and formulation evidence is identical for this pair. Preserve FDC 2708464 when this is the cited source; do not manufacture a nutritional distinction that the records do not show.

Exact-record context
What makes this USDA record distinct?
For FDC 2708464, the close-record rule searches the USDA “Ready-to-eat cereal, higher sugar (>21.2g/100g)” category for shared description terms or source inputs. Any surviving pair is compared per 100 grams, so unlike source-serving sizes cannot manufacture the nutrient difference.

Source-equivalent fields
Different source identities, matching published reference fields
Across the nutrient, portion, and formulation fields published here, FDC 2708464 and FDC 2708446 match exactly. Their descriptions and source identities remain distinct provenance; matching database fields do not make every real-world version interchangeable.
Practical reading: do not infer a nutrient difference from the names alone. Choose the description that more closely matches what was reported, while treating the shared values as a standardized reference rather than a measurement of your plate.
Evidence boundary: FDC 2708464 versus FDC 2708446 is a comparison of standardized source records—not a measurement of your meal, an overall food-quality rank, or proof that one input caused a difference.

Uncertainty, made actionable
What can change this estimate?
This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with portion size, recipe or brand, cooking fat, toppings and add-ins.
For “Cereal, O's, honey nut,” resolve portion size first, then move through the remaining 3 published levers. Unknowns should remain visible rather than expanding every assumption at once.
- 01
portion size
When composition is held constant, nutrient totals scale directly with grams. A 20% weight correction produces the same 20% correction to the scaled totals.
- 02
recipe or brand
Prefer a package, menu, or known recipe when it identifies the food more precisely. Otherwise preserve the generic record as an explicit approximation.
- 03
cooking fat
Match the named cooking-fat state when possible. Fat used, retained, or left behind is preparation information that a dish name alone cannot recover.
- 04
toppings and add-ins
Check whether the exact source description already includes it. If not, keep the addition separate rather than silently folding it into the base record.
How we estimated this
The arithmetic is simple; the provenance is the point
FDC 2708464 comes from FoodData Central Survey Foods (FNDDS). Its 385 kcal per 100 g becomes 154 kcal at 40 g through nutrient per portion = nutrient per 100 g × portion grams ÷ 100; this page adds no second nutrition estimate.
About the serving label: USDA describes the underlying survey portion as “Quantity not specified.” The separately listed 1 cup has the same gram weight, so the familiar label can be shown without changing the calculation.
Data cycle: 2021–2023, published October 31, 2024
FoodData Central ID: 2708464
FNDDS food code: 57241000
The scaling for FDC 2708464 can be exact while the match to “Cereal, O's, honey nut” is wrong. That is why this profile keeps its 40 g weight, 11-row source formulation, and selection uncertainty beside the arithmetic.
