Are Reese's Peanut Butter Cups good for weight loss?
At 515 calories per 100 g peanut butter cups are energy dense, and a two-cup package is about 232 calories with about 21.2 g of sugars. The same package has about 4.8 g of saturated fat, roughly a quarter of the FDA Daily Value of 20 g. Miniatures are the easiest way to keep a treat small at about 36 calories each, as long as you count them: five miniatures (35 g) are about 180 calories. Compared with a 2 oz Snickers bar at about 280 calories, a Reese's package is lighter per pack but denser per gram.
How to log Reese's Peanut Butter Cups in Cal.AI
Use Barcode on the wrapper or search "Reese's Peanut Butter Cups" in Cal.AI, then pick the package (45 g), a single cup (17 g) or the number of miniatures (7 g each). Do not log a two-cup package as two single cups: USDA lists the package at 45 g, while two 17 g cups come to only 34 g, about 57 calories less. Save your usual size so it is one tap next time.
Frequently asked questions
How many calories are in one Reese's cup?
USDA lists a single Reese's Peanut Butter Cup (0.6 oz, 17 g) at about 88 calories, with about 1.7 g of protein, 9.4 g of carbohydrate and 5.2 g of fat. A miniature (7 g) is about 36 calories. The cups in a standard two-cup package weigh more than that single cup, since the 45 g package comes to about 232 calories.
How many calories are in Reese's miniatures?
Each miniature peanut butter cup (7 g) has about 36 calories, with about 2.1 g of fat and 3.3 g of sugars, according to USDA data. They add up quickly from a bowl: six miniatures (42 g) are about 216 calories, close to a full two-cup package at about 232. Count the wrappers before you log them.
Are Reese's cups high in protein?
Not really. They have 10.2 g of protein per 100 g, more than milk chocolate or a Snickers bar, thanks to the peanut butter, but a two-cup package provides only about 4.6 g alongside about 232 calories. By energy they are about 51% fat, 41% carbohydrate and 8% protein, so they work as a treat rather than a protein snack.
