Can a tea detox make you lose weight fast?
If you see any product with the word "detox" in it, walk right on by. The only weight the detox will shed is from your wallet. Some "detox" protocols include food restrictions that place you in a deficit, and that's how you lose weight. In addition some have you go low or even no carb, so your body sheds it glycogen stores, and with each molecule of glycogen comes 3–4 molecules of water, and hence you lose water weight which will just come straight back when you resume eating carbs again.
But it's a scam to claim that any product can "detoxify" your body is any way shape or form. So just walk right on by.
