How do I view or change my weight loss zone? (iOS)

When you open your Noom app, you’ll see a calorie range called the Weight Loss Zone at the top of the page.

Your Weight Loss Zone represents a personal calorie range that’s calculated by factoring in your age, height, current weight, gender identity, and basic activity level to calculate the approximate number of calories your body uses in a day, based on the Harris-Benedict equation.

To lose weight, you have to expend more calories than you take in, which we call a caloric deficit. We subtract how many calories you need to burn to lose weight from your total daily energy expenditure (TDEE) while also eating a healthy number of calories to keep your body functioning at its best. This creates the Weight Loss Zone, which is a range of a few hundred calories.

Eating closer to the lower end of the Weight Loss Zone typically leads to greater weight loss (about 2 lbs or ~1 kg lost per week), while eating at the higher end of the Weight Loss Zone typically leads to a more moderate weight loss (about 0.5 lb or ~0.25 kg lost per week).

Your target calorie range is also updated each day based on the amount of activity you log, which you can read more about in the How does exercise or step count affect my weight loss zone? FAQ.

It’s important to note that you should be eating within the Weight Loss Zone, not below it. Your body needs calories to function, and even basic bodily functions like breathing and digestion require energy. Going below your zone can have negative consequences and isn’t sustainable in the long term.

We’ve honed in on giving you a calorie range rather than a precise number to hit because we know that not every day is the same. Consistently staying within your Weight Loss Zone each week is more important for building habits and reaching your weight loss goals than hitting an exact number each day.

However, if you’d prefer a specific calorie target, you can adjust the settings in your app so that you’ll have a designated number to hit each day rather than a Weight Loss Zone calorie range.

Adjusting Your Goal Weight

To adjust your Goal Weight:

1. Open Noom and tap the hamburger menu icon (three horizontal lines) in the top left corner of the screen
2. Tap Settings
3. Tap Weight and Calorie Settings
4. Tap Goal Weight to open up the slider bar
5. Slide your finger left or right across the slider bar to select your new goal weight
6. If needed, you can tap pounds, kilograms, or stones to toggle between these options

Adjusting Your Manual Calorie Adjustment

To adjust your Manual Calorie Adjustment:

1. Open Noom and tap the hamburger menu icon (three horizontal lines) in the top left corner of the screen.
2. Tap Settings
3. Tap Weight and Calorie Settings
4. TapManual Calorie Adjustment to open up the slider bar.
5. Slide your finger left or right across the slider bar to add any extra calories you want to be added to your weight loss zone.

Note: Make any manual adjustments to account for special circumstances and recommendations from your physician (e.g., lactating).

Adjusting Your Weight Loss Speed (if applicable)

To adjust your Weight Loss Speed:

1. Open Noom and tap the hamburger menu icon (three horizontal lines) in the top left corner of the screen
2. Tap Settings
3. Scroll down to Weight Loss Speed
4. You should see a turtle on the left, a hare in the center, and a cheetah on the right. The turtle means a slower weight loss speed, the hare means an intermediate weight loss speed, and the cheetah means a faster weight loss speed. Slide your finger left or right across the orange circle to adjust your weight loss speed.

Note: Depending on your app version, you may not have the Weight loss speed option as this is only available on the older versions of the app.

Minimum Calorie Range

To keep your body functioning at its best, Noom won’t let those who identify as female adjust their goal below 1,200-1,320 calories per day, those who identify as male below 1,400-1,540 calories per day, and those who don’t choose to select a binary gender below 1,200-1,320 calories per day. If you notice that your calorie goal isn’t changing when you adjust your settings, it may be that it’s already within the safe range for your current height, weight, and age.
