Two of the most popular serving sizes, a pint of beer and a quarter bottle of wine, are often mistakenly regarded as a standard drink where in fact they are equivalent to two standard drinks each. As a general guide for low-risk drinking, the recommended upper weekly limit used in Ireland is based on the UK unit – 14 units for women and 21 units for men. This involved multiplying the serving size of the drink (millilitres) by the alcohol content (% ABV) of the drink and dividing by 1.25 (1 ml=1.25 g) to establish the grams of pure alcohol in that specific drink (Table 1). To establish the standard drink in Ireland, the first step was to calculate the amount of pure alcohol in each of the alcoholic beverages.
It is therefore not appropriate to use the UK unit measure when describing a standard drink in Ireland. Although the UK unit was used in Ireland, it did not reflect the typical strength or serving measure of drinks sold in Ireland, where a single measure of spirits is larger, at 1/4 gill. A ‘UK unit of alcohol’ is found in a half pint of beer (3.5% ABV) or a small glass of wine (100 ml) or a single measure of spirits (1/6 gill) and equals 8 grams of pure alcohol. The measure used was called a ‘unit of alcohol’ and related to the most common drinks and alcohol content of drinks served in the UK. The purpose was to help scientists and health professionals in the clinical setting estimate alcohol consumption for comparative purposes. The UK unit was devised in the early 1970s as a simple method to calculate the alcoholic strength in different drinks. Part of the confusion stems from the use of the ‘UK unit’, which is inappropriate in the Irish context.

For extra reference in case you need it, we've included our alcohol conversion chart below, giving you the full rundown on different types of beverages. Therefore, in order to account for the "macro value" of alcohol, we assign the drink's calories to either carbs or fat instead. However, alcohol is not regulated by the FDA, so that information is not included on nutrition fact labels. Think of alcohol like a separate macro-while carbs and protein have 4 calories per gram and fat has 9 calories per gram, alcohol has 7 calories per gram. It is important that we track alcohol in the same way we track our food to ensure we're hitting our macros. If you are a current Macrostax user, simply click the " Add this to your food log" link to add the custom calculated alcohol macros to your day! *Note: you cannot use protein to account for alcohol
Or anywhere in between to use a combination of both carbs and fats so it fits your macros however you need it to
