The examples you sited consume such “miniscule” quantities of calories, I cann’t even believe it’s being seriously discussed. You’d burn more calories by chewing gum.
So you can lose weight by chewing gum too? There are some foods you can eat that will make you lose weight but I don’t recommend it. Once I ate a Mexican omelette at a small cafe. The chili in the omelette had been kept at the wrong temperature for too long. Trust me, by the time I fought off the food poisoning I had lost not just water weight but some fat and muscle as well. At one point when I was vomiting I swear I saw something that looked like an internal organ go by as well. I’d rather lose weight the old fashioned way, exercise and diet.
