When you think about what you eat, you probably picture plates. Drinks slip past. A can of fizzy drink, a glass of juice, a milky coffee with sugar and an evening beer can each look small, yet together they can add up to a whole meal's worth of energy, and they rarely fill you up the way food does.

Why drinks are easy to miss

Energy in a drink is real energy: sugar gives about 4 kcal per gram and alcohol gives about 7 kcal per gram, almost as much as fat. But liquid calories tend to feel less filling than the same energy eaten as food, so people often don't eat less later to make up for them. Studies on this are mixed in size, but the direction is consistent enough that health bodies advise paying attention to what you drink.

What counts as "free sugars"

Free sugars are sugars added to food and drinks, plus the sugars in honey, syrups, juice and smoothies. The NHS advises adults to have no more than 30 g a day, and a single can of cola can use up more than that. Sugar naturally inside a whole piece of fruit, or lactose in milk, is not counted the same way. Fruit juice and smoothies are limited to a total of 150 ml (a small glass) a day, ideally with a meal.

Water, tea and coffee without sugar, and milk are easy defaults. The calories to watch are in sweet drinks, juice and alcohol.

Easy, gentle swaps

You don't need to give up anything you love. If you want to change the numbers, small steps work well: choose a sugar-free or no-added-sugar version of your usual fizzy drink, dilute juice with water, take one less sugar in tea, or keep sweet drinks for meals rather than sipping them all day. If a drink is part of how you relax or socialise, that matters too, so pick the change that feels easy to keep.

When to talk to someone

This guide is general information, not medical advice. If you have diabetes, take medication, are pregnant or breastfeeding, have or have had an eating disorder, or want to change how much you drink, talk to a doctor or registered dietitian first. Do not cut energy below the usual minimums (about 1,200 kcal for women and 1,500 kcal for men a day) without professional advice.
