Frequently asked questions

What is Breastfeeding Calorie Calculator?

Extra daily calories while breastfeeding — about +500 kcal exclusive, with a gradual weight-loss option.

When would I actually use this?

Planning meals against a target, checking whether a habit covers the recommended intake, and translating a label into what it means for the day.

What is the most common mistake?

Treating a daily target as a daily requirement. Reference intakes are population averages over time; a day above or below one means nothing on its own.

How is Breastfeeding Calorie Calculator different from Alcohol Calorie Calculator?

They sit next to each other but answer different questions: Alcohol Calorie Calculator is the one to open when you need it to add up the calories of a drinking session from a library of beers, wines, spirits and cocktails, with a custom-drink option. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Calorie deficit calculator is the closest one after this: Find the daily calorie deficit to reach a weight-loss goal by a target date.

What else is worth having open alongside it?

Pregnancy Calorie Calculator and Daily calorie calculator (TDEE) — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Reference intakes come from public health bodies (EFSA in Europe, the NIH and USDA in the United States) and differ between them. They describe populations, not you, and are not medical advice.

ExplainerWhat Breastfeeding Actually Costs in Energy — and Why the Published Number Is Smaller Than the MilkMilk production has a computable cost: volume times energy density divided by the efficiency of conversion. Do the sum and you get about 675 kcal a day, not the 500 that gets quoted. Here is the derivation, why the published increment is deliberately lower, how much the real spread is between mothers, what the water requirement actually rests on, and why cutting calories while feeding is a clinical question.ExplainerEating for Two Is About Three Hundred Calories — and Almost None of Them in the First TrimesterThe extra energy a pregnancy costs is far smaller than the phrase suggests, and it arrives on a schedule: near zero in the first trimester, modest in the second, real in the third. Here are the published increments from EFSA, FAO/WHO/UNU and the 2023 US reference intakes, what they look like as food, and why protein and folate rise proportionally faster than calories do.ExplainerHow Much Milk Does a Baby Need? The Rule of Thumb and Its LimitsA formula-fed baby takes roughly 2.3 fl oz per pound of body weight per day in the first months, split across the day's feeds. Here is the table by age and weight, why breastfed babies are not measured this way, and the signs that outrank any number.Comparison16/8, 5:2 or Alternate Day: The Fasting Protocols ComparedFive protocols side by side, what each demands, and the uncomfortable finding from the controlled trials: matched for calories, fasting loses about the same weight as simply eating less.ExplainerHow Many Calories Are in a Pound of Fat?A pound of body fat holds about 3,500 calories.

A dry spirit is almost pure alcohol calories; a liqueur is nearly half sugar. Here is the derivation, the table, and the metabolic caveat stated without overclaiming.
