What Is A Calorie Deficit Diet?
A calorie deficit diet promotes the intake of fewer calories than the body burns. This causes a calorie deficit, where your body must use the stored energy and burn fat to make up for the missing calories. For instance, those with a daily caloric requirement of 2000 calories can create a calorie deficit of 500 calories by taking only 1500 calories. Their body will start burning fat to produce energy in an attempt to make up for this deficit. This, eventually, will lead to weight loss (1).
A calorie deficit is created by either consuming fewer calories, exercising more, or both.

Embarking on a calorie deficit diet involves careful planning to create a sustainable and healthy approach to weight loss and improved well-being. Take a look at the next section to understand how this diet works.

Following a calorie deficit diet without proper guidance can be difficult. But the following guide can help.
- Calculate the Maintenance Calories You Need: Determine your Total Daily Energy Expenditurei XTotal number of calories burnt in a day that depends on a person’s basal metabolic rate and physical activity level (TDEE), which takes your activity level and basal metabolic ratei XTotal number of calories needed to perform basic life functions like breathing, nerve function, and circulation (BMR) into consideration. You can use online calculators for this purpose.
- Set Your Calorie Deficit: Decide the number of calories you want to cut from your daily intake. A deficit of 300 to 500 calories per day is usually recommended to help lose 1 to 2 pounds per week.
- Select Nutrient-Dense Foods: Consume more of fresh fruits, healthy fats, vegetables, nuts, and legumes for sustainable weight loss (2).
- Portion Control: Monitor your portion sizes to avoid consuming excess calories. You can even measure and weigh your food to help track your caloric intake.
- Monitor Your Intake: Keep a food journal or use a calorie tracking app to help maintain your calorie deficit.
- Eat Several Small Meals Throughout The Day: Some research suggests that smaller, more frequent meals can help manage your appetite, keep your energy levels up, and reduce fat mass and body fat percentage (3).
- Exercise Regularly: A calorie deficit can also be achieved by engaging in physical exercises. Combine strength training with cardiovascular exercises like walking, running, or swimming to maintain your muscle mass and achieve healthy weight loss (4).
- Consult A Doctor: Speak to a licensed dietitian or healthcare professional before beginning a calorie deficit diet. They will provide a customized diet plan to make sure your dietary requirements are met.

Healthiest Ways To Cut Excess Calories From Your Diet
The following tips can help you slowly cut excess calories from your diet while enabling you to focus on balanced nutrition:
- Practice Mindful Eating: Mindless eating can often lead to overeating. Pay attention to your body’s hunger cues and focus on what and how much you are eating.
- Reduce Portion Sizes: Use smaller plates and bowls to help control portion sizes. If you are craving for something high in calories, consume that in a small portion to satisfy your taste buds.
- Limit Sugary And Processed Foods: Avoid sugary drinks, soda, snacks, and heavily processed foods as they lack nutritional value.
- Prefer Home-Cooked Meals: Cooking your own meals allows you to manage the portion sizes and control calories.
- Stay Hydrated: Drink enough water throughout the day, as thirst can sometimes be mistaken for hunger.
- Snack Wisely: Opt for healthy options like fresh fruits, vegetables, yogurt, or nuts. Avoid mindless snacking in front of the TV or computer.
- Practice Moderation: Enjoy occasional treats or have cheat days in moderation rather than completely cutting out everything. This can help prevent feelings of deprivation and can keep your cravings in check.
- Set Realistic Goals: Aim for gradual, sustainable weight loss rather than rapid changes that are difficult to maintain in the long-term.

![A calorie deficit diet may cause fatigue and weakness](https://cdn2.stylecraze.com/wp-content/uploads/2023/12/A-calorie-deficit-diet-may-cause-fatigue-and-weakness.jpg)
While a calorie deficit diet can be an effective tool for weight loss, it can pose the following risks and challenges:
- Nutrient Deficiencies: Restricted calorie intake can lead to vitamin C and zinc deficiencies, which may increase the risk of scurvyi XA disease that develops due to vitamin C deficiency and causes symptoms like bleeding gums and fatigue and immune system dysfunction (9), (10), (11).
- Muscle Loss: Inadequate protein intake on a calorie deficit diet may break down muscle tissue for energy. This can lead to muscle loss and a slower metabolism. A study found that a calorie deficit diet for weight loss can decrease lean mass. Hence, one should combine the diet with some physical activity to maintain muscle mass and strength (12).
- Fatigue And Weakness: A calorie deficit diet can cause fatigue, weakness, and reduced physical performance. This can make it a challenge to carry out daily activities. Prolonged calorie restriction can also decrease the energy needed for physical activity (13).
- Hormonal Imbalances: Long-term calorie deficit can significantly reduce androgeni XNatural or synthetic steroidal hormones, like testosterone, that regulate the development and maintenance of male characteristics and testosteronei XA male sex hormone that plays an important role in the development of male reproductive tissues and characteristics . This may increase the risk of infertility (14), (15).
- Mental Health Issues: Calorie restriction may cause feelings of deprivation, stress, and anxiety around food. This may potentially increase the risk of binge eating (13).
Conclusion
A calorie deficit diet can aid in weight loss when followed properly. It promotes the intake of fewer calories than your body expends. This results in gradual and sustainable weight loss. However, it is essential to strike a balance between reduced calorie intake and proper nutrition to prevent nutritional deficiencies and fatigue. Consume whole, nutrient-dense, protein-rich foods. Combine that with regular exercise to achieve the desired calorie deficit. Consult a doctor for a customized diet plan to help shed those pounds while also moving towards a healthier and energized you.
