Recently she shared with MyFitness Pal that when you’re working toward a weight-loss goal, it’s normal to be watching the number on the scale like a hawk waiting for any changes that might occur. But if you’ve been tracking your weight for even a few weeks, you’ve probably noticed fluctuations are common. Still, they can be frustrating to see when you’re working hard to get into your best shape ever.
Even for those who aren’t actively trying to lose weight, it can be unwelcome to see the scale jump up. Rest assured, weight changes from one day to the next are generally temporary and, according to experts, they don’t mean you’re not making progress.
Here, find eight explanations for why your weight can spike — straight from nutritionists who help people meet their weight-loss goals every day — that have nothing to do with gaining fat.
1. YOU DRANK A TON OF WATER
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. Why? “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 actually 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.”
