Claim: Absorbs all the water in your body so you can ‘shed’ pounds quickly.
“They’re terrifically healthy for you, full of beta carotene and fiber.” Aronica says that the fiber acts as a sponge and draws water out of your digestive tract. The benefit of this is that it makes the stool soft and large and reduces incidence of constipation, as well as drawing out harmful compounds (like cholesterol). But losing water temporarily won’t result in weight loss, and being dehydrated can cause constipation as the sponge like fiber tries to keep absorbing fluid in your gut. Definitely add them to your diet, but don’t expect them to cause weight loss.
