Question 1

How many calories in a veggie burger?

Accepted Answer

Portobello mushroom burger: 290 kcal. Black bean burger: 350 kcal. Falafel burger: 380 kcal. BK Veggie Burger: 390 kcal. McDonald's McPlant: 430 kcal. Five Guys Veggie Sandwich: 440 kcal. Wendy's Veggie Sandwich: 480 kcal. Beyond Burger (homemade): 490 kcal. BK Impossible Whopper: 630 kcal.

Question 2

Is the Impossible Whopper lower in calories than the regular Whopper?

Accepted Answer

Barely — only 40 kcal less (630 vs 670 kcal, a 6% reduction). The Impossible Whopper also has 9g more carbs and 100mg more sodium. Plant-based is not meaningfully lower calorie than beef in this format. The environmental and ethical case is stronger than the nutritional case.

Question 3

Are plant-based burgers (Beyond, Impossible) healthier than beef?

Accepted Answer

Different rather than simply healthier. Advantages: zero cholesterol, more fibre, no haem iron. Disadvantages vs lean beef: more sodium (Beyond patty 390mg vs lean beef ~80mg), more processed, similar saturated fat. Beyond patty: 250 kcal, 20g protein, 18g fat. 80/20 beef patty: 287 kcal, 19g protein, 23g fat. Beyond is slightly lower fat; similar in protein.

Question 4

What is the lowest calorie veggie burger?

Accepted Answer

Portobello mushroom burger (~290 kcal) — the mushroom cap itself is only ~26 kcal. Black bean burger (homemade, no mayo): ~280–320 kcal. At chains: BK Veggie Burger (390 kcal) is the lowest among major chain options — 240 kcal less than the Impossible Whopper.

Question 5

Are veggie burgers good for weight loss?

Accepted Answer

Depends on the type. Bean-based (350 kcal, 8g fibre) and mushroom (290 kcal) support calorie control. Plant-based (Beyond/Impossible) are NOT lower calorie than many beef burgers. The Impossible Whopper (630 kcal) is more than double a McDonald's Cheeseburger (300 kcal). Fibre in bean-based patties increases satiety.

Question 6

What is the difference between Beyond Burger and Impossible Burger?

Accepted Answer

Beyond: pea protein, coconut oil + cocoa butter, beet juice colouring. Per patty (113g): 250 kcal, 20g protein, 18g fat, 5g sat fat, 390mg sodium. Impossible: soy protein, sunflower + coconut oil, soy leghemoglobin (haem substitute). Per patty: 240 kcal, 19g protein, 14g fat, 8g sat fat, 370mg sodium. Beyond is soy-free; Impossible closely mimics beef flavour. McDonald's McPlant uses Beyond; BK uses Impossible.
