# Why Does My Weight Go Up Sometimes Even When I'm in a Calorie Deficit?

If you've been following a calorie deficit but the number on the scale goes up one morning, don't panic. Daily weight fluctuations are completely normal and do not necessarily mean you've gained body fat. In fact, your body weight can change by several pounds over the course of a few days, even while you're consistently losing fat. We will show you today, on how start tracking and staying calm can help if this happens.

<Note>
  The key is to focus on long-term trends rather than individual weigh-ins.

## Water Weight Changes Constantly

One of the biggest reasons your weight changes from day to day is water.

Eating a meal that is higher in carbohydrates or sodium can cause your body to temporarily hold more water. Drinking more fluids, changes in hormone levels, and even a tough workout can also affect how much water your body stores.

Women may notice even larger fluctuations throughout different stages of their menstrual cycle due to hormonal changes. Men experience weight fluctuations as well, although they are often less noticeable. In both cases, these short-term changes are completely normal and should not be confused with body fat gain.

## Food Still Inside Your Digestive System

Your body weight also includes the food and liquids that are still being digested.

For example, if you eat a large dinner the night before weighing yourself, you may simply have more food in your digestive system the next morning. That extra weight has nothing to do with fat gain.

## Look at the Trend, Not Today's Number

One of the biggest mistakes people make is letting a single weigh-in determine how they feel about their progress.

Imagine you weighed **220 pounds** twelve weeks ago and today your long-term trend has brought you down to **201 pounds**. If you step on the scale tomorrow and it reads **203 pounds**, that does not mean you've suddenly gained two pounds of body fat or that your calorie deficit has stopped working. More often than not, it is simply normal day-to-day fluctuation caused by water, food, sodium, or other temporary factors.

<Tip>
  What matters is the direction your average weight is moving over weeks and months, not what happens on any single morning.

## Track Your Progress Over Time

This is one of the reasons using a tracking app can be so helpful. Instead of relying on memory or worrying about individual weigh-ins, you can see your long-term progress clearly.

GetFIT App, our online body transformation membership, makes it easy to track your body weight, meals, calories, protein intake, workouts, and other progress in one place. Looking at your weekly and monthly trends gives you a much more accurate picture of your results than focusing on a single day's number.

## Weigh Yourself Consistently

To get the most reliable picture of your progress, try to weigh yourself under similar conditions each time.

A good approach is to weigh yourself:

* First thing in the morning
* After using the bathroom
* Before eating or drinking
* Wearing similar clothing, or no clothing at all

When you stay consistent with your calorie deficit and keep an eye on your long-term trend instead of daily fluctuations, you'll have a much better understanding of your actual progress. A small increase from one day to the next is normal.

  What matters is where your weight is heading over the course of several weeks, not what the scale says on any single day.
