Calorie counting
Calorie counting is arithmetic before it is discipline: a daily number, a way to log what you eat, and enough consistency that two weeks of data mean something. These guides cover each part. They explain where a daily target comes from (the Mifflin-St Jeor equation, published in the American Journal of Clinical Nutrition in 1990, is the one behind most calculators), how to estimate a portion when there is no scale in the room, how to read the serving size on an FDA Nutrition Facts panel, and which everyday habits quietly hide a few hundred calories. General information, not medical advice.

Questions this section answers
One question from each guide below, answered here. Follow a question to the guide that works through it in full.
- How long do you have to track calories before it tells you anything?
-
Three weeks, read as three weekly weight averages against three weeks of logs. Anything shorter is dominated by water and glycogen shifts rather than by energy balance. After that first block, most people find the daily work drops sharply, which matches the Harvey finding that average logging time fell from 23.2 minutes a day in month one to 14.6 minutes by month six.
The Best Way to Track Calories for Beginners → - How accurate is estimating portions by hand?
-
Expect to be within roughly a quarter of the true amount on solid foods, and further off on anything mixed, fried or sauced. That level of error is tolerable because it repeats: if you overestimate rice by the same margin every day, the trend on the scale is still honest. What breaks a log is not the size of the error but its variability, and the meals you never record at all.
How to Track Calories Without Weighing Your Food → - Can you gain weight while eating in a deficit?
-
Yes, on the scale and for short periods. Salt, carbohydrate refeeding, a new training program, poor sleep and constipation all add water or mass without adding fat, and any of them can outweigh a week of fat loss. Kreitzman and colleagues documented the glycogen and water version of this in 1992. Read weekly averages across three weeks before treating an increase as real.
Why Am I Not Losing Weight in a Calorie Deficit? → - Is a local-only health app safer?
-
They remove one category of risk completely: with no server holding your history, no server breach can expose it. They do nothing about a lost or unlocked phone, which becomes the single copy of everything. Set a passcode and keep the system backup on.
Health Apps Without an Account: What Stays on Your Phone → - How long does it take to find your maintenance calories?
-
Three weeks of consistent eating and daily weighing, read as three weekly averages. Shorter windows are dominated by water and glycogen shifts rather than by energy balance, which is why a flat week or a heavy week proves very little on its own. If the three weekly averages hold within about a pound, the intake you ate is your maintenance level.
Maintenance Calories: What They Are and How to Find Yours → - Is the 3,500 calories per pound rule wrong?
-
It is right about tissue and wrong about time. A pound of body fat really does hold about 3,500 calories, the figure Wishnofsky published in 1958. Applied as a weekly forecast it overshoots, because expenditure falls as body weight falls. Thomas and colleagues demonstrated the overestimate against supervised trials in 2013 and recommended dynamic models instead. Keep the rule for setting a target, not for predicting a date.
How Many Calories to Lose a Pound? → - Can you lose weight by tracking macros and ignoring calories?
-
Yes, but only because macros contain calories. Hitting fixed gram targets for protein, carbohydrate and fat fixes the calorie total automatically, since the three multiply out at 4, 9 and 4 calories per gram. Tracking macros without noticing the total is not a different mechanism, it is the same mechanism with an extra step and more room for arithmetic to slip.
Calories vs Macros: What's the Difference? → - Is the hand method accurate enough to lose weight with?
-
For most people, yes, provided it is calibrated once and used consistently. Direction matters more than precision: a method that is 15% off in the same direction every day still shows a real trend on the scale over a month. What defeats weight loss is not a rough estimate, it is an incomplete log with meals missing from it entirely.
How to Estimate Portion Sizes With Your Hand → - How many calories a day do these mistakes typically hide?
-
The published estimates are large. Lichtman and colleagues measured a gap of just over 1,000 calories a day between what participants reported and what they ate, and the CDC's 145-calorie daily average from sugar-sweetened beverages is one item inside a gap that size. A deficit of 500 calories a day disappears entirely inside errors of that scale.
7 Common Calorie Counting Mistakes (and How to Fix Them) → - Do the calories on a label include fiber?
-
Yes, in the United States. Total Carbohydrate on the FDA panel includes dietary fiber, and fiber grams are listed underneath as a subcategory rather than deducted. The "net carbs" figure some brands print on the front of the box is not an FDA-defined term and does not appear on the Nutrition Facts panel, so it cannot be compared across products the way %DV can.
How to Read a Nutrition Label (Without Overthinking It) → - Is a kcal the same thing as a calorie?
-
On a nutrition label, yes. One food Calorie equals one kilocalorie, which is 1,000 of the small calories used in physics. American labels write "Calories" and most scientific sources write "kcal" for the same quantity, which is why USDA FoodData Central lists energy in kcal. A 500-kcal meal and a 500-Calorie meal are identical.
How Many Calories Should You Eat a Day? → - Does counting calories from a photo work without an internet connection?
-
No. The image has to be analyzed on a server, so the phone needs a connection at the moment you submit the photo. Everything else in Kalo.Quest works offline: the day's log, the weight and activity history, the weekly and monthly averages, and the progress photos, which stay on the phone. Only the analysis step requires a network.
