Alcohol and Your Goals
How drinking affects your weight, training and recovery
Alcohol is part of social life for many people, and it does not have to derail your goals. But it is worth understanding what it does, so you can make informed choices. Here is the honest picture.
The basics
- Alcohol provides 7 kcal per gram, almost as much as fat, with no useful nutrients.
- UK guidance: keep to under 14 units a week, spread over at least 3 days, with drink-free days.
- Drinks are often mixed with sugary, calorie-dense mixers that add up fast.
Alcohol and weight
Alcohol is not stored as fat directly, but your body burns it first, so the calories from your food are more likely to be stored while it does. It also lowers your inhibitions around food, so late-night eating creeps in. It is an easy and often-forgotten source of calories.
In numbers: a pint is around 180 kcal and a large glass of wine around 190 kcal. Cutting roughly 4 drinks a week saves about 750 kcal, which could add up to around 5 kg over a year if those were surplus calories. There are about 7,700 kcal in 1 kg of body fat, so small, consistent changes add up. Try our Alcohol Units and Calories tool to see your own numbers.
Alcohol and training
- It is a diuretic, so it worsens hydration and slows recovery.
- It reduces muscle repair (protein synthesis), even when you eat enough protein.
- Even small amounts before exercise can reduce endurance, coordination and judgement.
- It disrupts sleep quality, which hits recovery and your energy the next day.
