Can my TDEE change if I switch to a sedentary lifestyle

I understand that changing your lifestyle can be a significant concern, and it's great that you're taking the time to consider how these changes might affect your health. To address your question, yes, your Total Daily Energy Expenditure (TDEE) can change if you switch to a more sedentary lifestyle. TDEE is the total number of calories your body burns in a day, which includes your Basal Metabolic Rate (BMR) and the calories burned through physical activity. When you adopt a sedentary lifestyle, your physical activity level decreases. This decrease will lower the number of calories you burn through daily activities such as exercise, walking, and even fidgeting. With less movement, your body will require fewer calories to maintain its current weight. It's important to consider the implications of this change. If you continue to consume the same number of calories that you did when you were more active, it could lead to weight gain over time. Conversely, if you're aware of your new TDEE and adjust your caloric intake accordingly, you can help maintain a healthy weight. In summary, a shift to a sedentary lifestyle will typically lower your TDEE, so it's essential to pay attention to both your physical activity levels and your caloric intake to ensure you remain healthy. If you're looking for ways to adapt to these changes or want personalized advice, consider talking with a healthcare professional who can offer support tailored to your specific situation.
