Alcohol is where things can get tricky, as calories, fat, sugar and carbohydrates aren’t required to be listed on labels.

Both teas play a role in microbial gut health leading to an anti-obese environment," explains Valdez. "Overall, whether it be green tea, black tea, white tea, or lemon tea, they all have zero calories and provide hydration, which can be an opportunity to assist with weight loss versus consuming sugary beverages or alcohol. If you want a little antioxidant water, tea is a nice choice. And if you can't tolerate coffee, tea is a perfect substitute."

But following a detox diet full of natural foods can enhance the body's ability to cleanse. He adds, however, that dieters should make no assumptions about health when choosing a detox diet. "Detoxes have gotten very trendy, and many of them are unhealthy and quite dangerous."
