What Happens to Your Body When You Start Cutting Calories

When you start cutting calories, there are various changes that take place within your body. These changes mostly depend on the amount of calories you are cutting and the time frame in which you have been cutting the calories. Generally, if the calorie deficit you create is more than 1000 calories per day, it can have drastic effects on your body. Here are some of the ways that your body will be affected when you start cutting calories:

Changes in Energy Levels

  • Short-term effects – you will likely experience a decrease in your energy levels as your body adjusts to the changes in food intake.
  • Long-term effects – If the calorie restriction is maintained for an extended period of time, your energy levels may rise slightly as the body gets used to the reduced calorie intake.

Weight Loss

Cutting calories is a great way to help you reach your weight loss goals. As the number of calories you consume is reduced, your body will be forced to draw on stored energy (in the form of fat) to make up for the missing calories. As a result, you should begin to experience steady weight loss over time.

Changes in Nutrient Processes

When you start cutting calories, your body’s ability to adequately process and utilize nutrients from food can decline over time. This is because your body has to work harder to utilize the same amount of nutrients from fewer calories. As a result, you may experience fatigue and other issues such as muscle aches and a weakened immune system.

Hunger and Cravings

One of the common effects of calorie restriction is an increase in hunger and cravings. This is because your body is used to getting a certain number of calories on a regular basis and when that number is suddenly reduced, your body starts sending signals that it needs more food. This is why it is important to ensure that you are eating a nutritious and balanced diet when cutting calories.



Cutting calories can be an effective way to lose weight, but it is important to keep in mind the potential effects it can have on your body. When cutting calories, make sure to ensure you are getting an adequate amount of nutrients and calories to ensure that you are maintaining your health while still reaching your goal of weight loss.
