Autumn Calabrese gives her No. 1 Tip for losing weight

Autumn Calabrese has a wealth of knowledge when it comes to what people need to get in shape, but her No. 1 diet and wellness tip is surprising.
In fact, you probably have the ingredient readily on tap.

"Drink water," she said in a phone interview with Business Insider. "Yeah, portion control is really important, too, [but] it's amazing how many Americans are actually dehydrated, and that leads to so many problems."

And many times you reach for that bag of chips, you might just be thirsty.

"Our bodies can't really tell the difference between hunger and thirst," she said, "so a lot of times people are dehydrated and they think they're hungry, so they go eat when really they just need ... a glass of water."
"That's what our bodies are made of ... it's what flushes our system ... keeps us going," she said. "Being dehydrated is a miserable feeling; I've done it for competitions ... so my biggest tip is actually drink your water."
