When aiming for weight loss, it’s generally recommended to create a moderate calorie deficit. A moderate deficit allows for steady and sustainable weight loss without compromising your overall health and well-being. 

To determine an appropriate calorie deficit, you need to consider your individual needs and goals. Typically, a deficit of 500-1000 calories per day is considered a reasonable range for most people.

In your case, if your Total Daily Energy Expenditure (TDEE) is approximately 2000 calories and you burn an additional 1000 calories through exercise, your total energy expenditure would be around 3000 calories. 

To create a moderate calorie deficit, you could consider reducing your daily caloric intake by 500-1000 calories. This would put you in a range of 2000-2500 calories per day, depending on your specific target deficit.

It’s important to note that individual needs vary, and it’s recommended to consult with a registered dietitian or healthcare professional for personalized advice based on your unique circumstances, goals, and any underlying health conditions.

Additionally, it’s essential to prioritize a balanced diet that provides adequate nutrition and to focus on the quality of the calories you consume rather than solely focusing on the quantity. Combine your calorie deficit with regular physical activity, strength training, and other healthy lifestyle habits to support your weight loss journey.
