Why did I gain 5 lbs in one day?
Daily weight fluctuation is normal. The average adult's weight fluctuates up to 5 or 6 pounds per day. It all comes down to what and when you eat, drink, exercise, and even sleep.
"We can weigh 5, 6, 7 pounds more at night than we do first thing in the morning," Hunnes says. Part of that is thanks to all the salt we consume throughout the day; the other part is that we may not have fully digested (and excreted) everything we at and drank that day yet.
Bloating, gut health issues and hormonal changes can make you hold onto more water weight. The water weight usually settles down after your period. If you are not regular, or your fiber intake has been inconsistent, this can be a reason why you gained weight overnight.
Why does my weight fluctuate so much? “Everyone's weight fluctuates throughout the day, and especially from morning to night,” says dietitian Anne Danahy, MS, RDN. “The average change is 2 to 5 pounds, and it's due to fluid shifts throughout the day.” If you see fluctuations of less than 5 pounds, you needn't worry.
The length of time that it takes to lose water weight depends on how much water you're retaining, the cause of the water weight gain, and the action taken to lose it. If you have one high-sodium meal and then return to normal, healthy dietary habits, you'll likely return to your normal weight in 1-2 days.
- Drinking more water.
- Avoiding super salty and sugary foods.
- Exercising regularly.
- Eating hydrating foods.
- Reducing carbohydrates.
- Trying supplements or water pills.
- Improving your sleep.
- Decreasing stress.
Here's Why Your Weight Might Be Higher
Let's talk about the most likely possibilities for your five-pound weight gain. James says that drinking water, eating late at night, and consuming extra carbs (which your body stores in water) can all influence the number on the scale. So can your menstrual cycle.
The bottom line is that a 1000-1500 surplus of calories for a day means you'll only gain about 0.70-112 grams of fat. The scales might say you've gained more, but that's because of the water weight excess sodium and carbohydrates bring along with it.
It can be useful to remember that, just as one day of dieting will not cause a person to lose weight, a day of binge eating will not cause weight gain. Although an episode of overeating can happen to anyone occasionally, some people have a binge eating disorder, which usually requires professional attention.
Sudden weight gain -- 2-3 pounds in a day or more than 5 pounds a week -- could mean it's getting worse. You also might have swollen feet and ankles, a faster pulse, heavy breathing, high blood pressure, memory loss, and confusion. You might want to track these symptoms so you can tell your doctor about abrupt changes.
