Alcohol: the calories that vanish from most food logs
Seven calories a gram, almost nobody logs it, and it suppresses fat oxidation while it is being processed. The arithmetic is less forgiving than the culture around it.
Alcohol is the most consistently missing item in food logs. Not because people are dishonest, because a drink does not feel like food, and logging apps do not make it easy.
The arithmetic does not care.
Seven calories a gram
Alcohol sits between carbohydrate and protein (4 cal/g) and fat (9 cal/g), at about 7 calories per gram. A standard drink holds roughly 14 g of alcohol, about 98 calories before anything else.
Then the mixer:
| Drink | Calories |
|---|---|
| Light beer, 12 oz | 100 |
| Regular beer, 12 oz | 150 |
| IPA, 12 oz | 200–250 |
| Wine, 5 oz | 120–130 |
| Spirit, 1.5 oz neat | 100 |
| Gin and tonic | 180 |
| Margarita | 250–450 |
| Piña colada | 400–600 |
Four beers on a Friday is roughly 600–1,000 calories. A weekly routine of that is 3,000–5,000 calories a month that never touched the log.
The metabolic part, honestly
There is a real effect and it is smaller than the internet suggests.
The body cannot store alcohol, so it prioritizes clearing it, and fat oxidation is suppressed while that happens. Real, measurable, and temporary, hours, not days.
The bigger effect is behavioral, and everyone recognizes it: alcohol lowers inhibition around food. The late-night order is usually a larger line item than the drinks.
Where the guidance sits
US guidance is up to two drinks a day for men and one for women, and this is one of the areas that has been tightening, several health bodies have moved toward saying there is no intake with a clear net benefit. The old "red wine is good for you" story has not held up well.
This article is not going to tell you what to drink. It is going to tell you to count it.
Cap it weekly, not daily
Alcohol is the clearest case for a weekly cap rather than a daily one.
A daily limit either forbids a normal Friday or is set so loosely it never triggers. A weekly one, say ten drinks, matches how the thing is actually consumed, and it lets a big Saturday coexist with five dry days without either feeling like a failure.
That requires a tracker that understands ceilings and weekly windows, which most do not. In AIM you can add "alcohol units" as a custom metric with a weekly cap, and get flagged by the drink that crosses it rather than by a summary at midnight. The caps article covers the setup.
The simplest thing
If you take one thing: log the drinks.
Not to feel bad about them. Because a log missing 800 calories a week is not a slightly incomplete picture; it is a misleading one, and it is the reason a lot of people conclude that tracking does not work for them.
Common questions
- How many calories are in alcohol?
- Pure alcohol provides about 7 calories per gram, between carbohydrate and protein at 4 and fat at 9. A standard drink contains roughly 14 g of alcohol, so about 98 calories before anything it is mixed with.
- Does alcohol stop fat burning?
- While alcohol is being metabolized the body prioritizes clearing it, which suppresses fat oxidation during that window. The effect is temporary. The larger issue for body composition is usually the calories themselves plus what people eat while drinking.
- Should I log alcohol in a food tracker?
- Yes, and it is the item most often left out. A few drinks across a week can be a thousand calories that never appear in the log, which makes the rest of the data misleading rather than merely incomplete.

Caps, not goals: limiting soda, sugar and seed oils
Most trackers only know how to count up toward a target. Some of what you eat needs a ceiling instead, a number to stay under, with something that says so when you pass it.
Calorie labels are legally allowed to be wrong
The FDA permits up to 20% variance on declared calories, and restaurant meals are routinely further off than that. Which changes what a tracking number is actually for.
Seed oils: what the evidence actually shows
One of the loudest nutrition arguments online, and the research is far less dramatic than either side claims. Here is what is established and what is inference.
