If your goal is to speed up your metabolism and lose weight, then you have to try eating more spicy foods, like gochujang jjigae, because fermented red pepper paste contains capsaicin, which can naturally stimulate your metabolism.
Add gochujang and water or broth to a small pot. Stir and bring to a boil. Add garlic, potatoes, zucchini, and mushrooms and simmer until potatoes are soft, about 10 to 15 minutes. Add tofu at the end, then top with green chili peppers.
