It’s true that staying well-hydrated is a good move if you’re trying to lose weight, but the first few days of upping your water intake could actually cause the number on the scale to creep up, too. “Let’s break down what weight really is,” says Megan Ware, RDN. “It is not just the measurement of fat in the body. It is the weight of your bones, organs, muscles, fluid and waste. When you’re dehydrated, you weigh less, but that doesn’t mean you are healthier. Let’s say you don’t drink much fluid one day, and the next morning you wake up and your weight is down. Then you drink a ton of water, and the next day, it looks like you gained 2 pounds. That does not mean you gained 2 pounds of fat; it just means that your body was depleted of water the day before.”
