Light beer has 46 kcal per 100 g — about 30% fewer than regular lager. A 500 ml bottle runs ~230 kcal versus ~215 for full-strength. The combined meta-analysis of 599,912 drinkers (Wood et al., Lancet 2018) found life expectancy drops above ~100 g alcohol per week.
How should I track Alcoholic beverage, beer, light, higher alcohol?
Liquid calories from Alcoholic beverage, beer, light, higher alcohol are easy to overlook because drinks do not trigger the same fullness signals as solid food. A meta-analysis (Wehling & Lusher, Am J Clin Nutr 2021) confirmed that people underreport beverage intake more than solid food. Most people pour 30–50% more than the label serving size without realizing it. Use a kitchen scale to weigh your glass or bottle once — you will know your exact pour going forward. This one calibration step can save you from hundreds of untracked calories per week.
