Alcohol doesn’t have to be off the table. It just behaves differently to everything else you eat, and once you know how, it stops catching you out.
It isn’t really a macronutrient, but it delivers calories like one: 7 per gram, closer to fat than to carbs. That part is easy enough to plan around. The three things that come with it are what quietly cost people progress.
“The drinks are rarely the biggest issue. What comes after them usually is.”

Fat
Nearly as calorie-dense as fat, with none of fat’s satiety or nutritional value.
Three complications food doesn’t have
Every other calorie source tells you something. Protein sends the strongest fullness signal, fibre slows digestion, fat and carbs trigger the hormones that say stop. Alcohol sends nothing, so two glasses before dinner don’t make dinner smaller. They get added to it.
It also lowers your guard, including the one that keeps your food choices sensible. And while it’s in your system your liver clears it first, so fat burning waits its turn. Drink heavily after training and muscle repair slows too.
Zero satiety
No fullness signal, so it adds rather than replaces
Lowers your guard
Worse choices, bigger portions, later at night
Pauses fat burning
Your liver clears alcohol first, fat oxidation waits
What your drinks actually cost
None of these are off-limits. They’re just easier to plan for once you know the number.

Three drinks on a Friday is often 400–600 kcal, before any food that follows. Approximate, and it varies by brand and ABV.
Moderate drinking, tracked, doesn’t derail you
Small and modest amounts, accounted for, have little measurable effect on fat loss or muscle retention. The clear negative effects start around the point where you’re drinking enough to feel drunk. One or two, planned and logged, fits a plan that works.
What derails people isn’t the wine. It’s the unlogged wine, and the food that follows it.
How to plan a night out
A rough plan beats no plan. And one night out never changes your results, only treating it as a write-off does.
Before you go
Eat protein and vegetables first. Hardest to make up later, and it blunts the effect of drinking on an empty stomach.
Make a buffer. Trim carbs or fat slightly at earlier meals. A skipped slice of toast does it, no need to starve.
Pre-log the drinks. Decide before you’re in the room, and you’ll see exactly what’s left for food.
Keep protein non-negotiable. Drinks come out of carbs and fat, never out of overnight recovery.
Log it the next morning and move on. Water, a balanced meal with protein, back to normal.
TRY THIS TODAY
Next time you drink, log it before you go out, not after. Seeing the calories already accounted for changes the decisions you make in the room.
IN KAIORA
Kaiora logs alcohol alongside your food so nothing disappears into a blind spot, and handles the macro conversion for you, you enter the drink and it does the maths. Recommendation: eat before you go, hydrate during, a realistic reset the morning after. Never to make you feel monitored.
The science
Norton & Baker, Fat Loss Forever, on calorie density, fat oxidation and moderate intake. Parr et al. (2014), PLoS ONE: alcohol after training measurably reduced myofibrillar protein synthesis even with protein held constant.
