USDA numbers for plain milk chocolate M&M's per 1.69 oz package, per serving and per 10 pieces, with the sugar and saturated fat.

By the Cal.AI Team · Published · 3 min read

Short answer 100 g of M&M's (milk chocolate) has 492 calories (USDA). A typical serving, 1 package (1.69 oz, 48 g), has about 236 calories with 2.1 g protein, 34 g carbs and 10 g fat. That package holds about 30.6 g of sugars, so most of its carbohydrate is sugar.

M&M's are small enough to eat by the handful without counting, which makes them easy to undercount. USDA lists the plain milk chocolate version at 492 calories per 100 g, and 10 pieces weigh about 7 g, so each candy is roughly 3.4 calories. Peanut and other varieties are different foods with their own numbers.

Are M&M's (milk chocolate) good for weight loss?

At 492 calories per 100 g M&M's are energy dense, and the candy-coated pieces are easy to eat without noticing. A 1.69 oz package carries about 30.6 g of sugars and 6.3 g of saturated fat, close to a third of the FDA Daily Value of 20 g. If you want a few, count out a serving (21 g, about 103 calories) into a bowl instead of eating from a larger bag. Per 100 g they sit almost level with a Snickers bar at 491 and a little below milk chocolate at 535, so the candy shell does not make them a light option.

How to log M&M's (milk chocolate) in Cal.AI

Scan the barcode on the package or search "M&M's" in Cal.AI, then set the amount: 48 g for a 1.69 oz package, 21 g for a serving or 7 g per 10 pieces. If you ate from a bowl, count the pieces and log them in tens, about 34 calories each time, using the serving + control. The common mistake is logging a handful as one 21 g serving when you ate more, so count or weigh when you can.
