Perhaps you can do some research online
to learn whether there are ways,
foods, liquids,
to increase your basic
metabolism. If you were too slender, and have the same hunger habits, I would suspect you have contracted a parasite, like a tapeworm. Poor people walk in bodily waste, and hookworms and other parasites get into their bodies and remain for years. Why not go to Google and type, "how to increase ones metabolism?"Or, foods that increase your metabolism.
