The Whopper Jr. is the smaller cousin of the classic Whopper, built around a single flame-grilled beef patty with the same familiar toppings — lettuce, tomato, onion, pickles, ketchup and mayo on a sesame bun. Because it keeps one patty instead of the full-size stack, it lands at a lighter calorie count while holding on to the same flavor profile.
Per 100 g, Whopper Jr. carries about 225 kcal, 9.7 g protein, 18.6 g carbs, 12.4 g fat and 2.2 g fiber. The bun drives most of the carbs, while the patty and mayo account for much of the fat, so changes to those two parts move the numbers the most.

What Are the Protein, Carb and Fat Macros?
A single Whopper Jr. provides roughly 14.1 g protein, 27 g carbs and 18 g fat. The beef patty is the main protein source, the bun supplies most of the carbohydrate, and the fat comes from the patty and the mayo together. Pairing it with water instead of a soda, and a side salad instead of fries, keeps the meal closer to the burger's own numbers.
