“Generally, studies have shown that on average a meal containing a spicy dish, like a bowl of chili, can temporarily increase metabolism by about 8 percent over a person’s normal rate, an amount considered fairly negligible.”
The calories in Sriracha are so low that they are likely “cancelled out” by an increases metabolism of let’s say 5%. So if a meal was 500 calories and normally you’d straight up burn off 70%, instead of 350 calories, you’d be burning 367 calories while of you added a tablespoon of Sriracha (15 calories). This is just a big sloppy for instance, I don’t know enough about metabolism to say this is 100% correct. Just a little about math.
