Energy comes from USDA nutrient 1008. Salt is calculated as sodium × 2.5, with unit conversion to grams. It is not a separately measured salt value.
Preparation
Light beer is 29 kcal per 100 ml against regular beer's 43 — about a third less, achieved by fermenting more of the carbohydrate and diluting what remains, which is why it also carries less alcohol. Nothing in the glass changes that. As with all alcohol, the energy is mostly ethanol at 7 kcal per gram, and it appears on no label in most markets.
Logging this food
A 12 fl oz can or bottle is 354 g and 103 kcal; a fluid ounce is 30 g and 9. The saving against regular beer is 50 kcal a can, which is real but easily undone: five light beers is 515 kcal against three regular ones at 459. Count the cans, not the label.
Swaps and alternatives
Regular beer is 43 kcal per 100 ml. A glass of wine is 123 kcal for 5 fl oz and a jigger of spirits 97 — a spirit with a zero-calorie mixer is the lightest drink in this family per unit of alcohol. The saving that dominates all of them is the number of drinks.
