Why Understanding Your TDEE Matters at Slym Wellness Clinic
Why TDEE Matters at Slym Wellness Clinic
At Slym Wellness, we take a whole-body approach to wellness, combining data-driven insights with personalized care. Understanding your TDEE helps our providers design a plan that supports:
Healthy weight management
Hormonal balance and energy restoration
Improved body composition
Enhanced metabolism and recovery
Our goal isn’t just calorie control, it’s metabolic optimization through nutrition, movement, and clinical support.
Understand Your Daily Calorie Needs
IMPORTANT DISCLAIMER: This calculator is for educational purposes only and does not determine eligibility for medical treatment. A licensed healthcare provider must review your full health history to make personalized recommendations.
Your Total Daily Energy Expenditure (TDEE) represents how many calories your body burns each day through basic functions (breathing, circulation, digestion) and daily activity. Understanding your TDEE helps you make informed decisions about nutrition, fitness, and weight management—whether your goal is fat loss, maintenance, or body recomposition.
Our free TDEE Calculator estimates your daily calorie burn and gives you insight into how many calories to eat to reach your goals.
How Does It Work?
Enter your age, height, weight, sex, and activity level into our calculator above.
Once complete, you’ll see three results:
Calories to maintain your current weight
Calories to lose 1 lb per week
Calories to lose 2 lbs per week
Your TDEE result shows how much energy your body uses in a typical day. From here, you can adjust your intake to align with your goals.
After identifying your TDEE, you can set your calorie goal:
Maintenance: Eat close to your TDEE to maintain your current weight.
Weight Loss: Create a moderate calorie deficit (commonly 500–750 calories per day).
Muscle Gain: Add 250–500 calories above maintenance to support muscle growth.
Tip: Sustainable changes matter more than aggressive deficits. Extreme calorie restriction may reduce metabolism and increase fatigue—especially for those on GLP-1 medications.
Determine your TDEE using the calculator.
Choose your target—maintenance, fat loss, or muscle gain.
Pair with a nutrition plan that supports your goal.
Re-evaluate monthly or quarterly, as metabolism adapts over time.
At Slym Wellness, we often pair TDEE insights with other metabolic calculators, like our Lean Body Mass, Protein Intake, or Calorie Deficit tools, to create a comprehensive wellness plan.

Your metabolism is unique, and your plan should be too.
Use this TDEE calculator as your first step toward better metabolic awareness, then connect with your Slym Wellness provider to review your results and design a personalized approach to nutrition, hormones, and long-term wellness.
Understanding TDEE: The Energy Balance Equation
Your total daily energy expenditure combines several key components:
Basal Metabolic Rate (BMR):
Energy needed to sustain vital body functions at rest—commonly 60–70% of total calories.Non-Exercise Activity Thermogenesis (NEAT):
Energy burned through daily movement—walking, standing, fidgeting, and posture maintenance.Exercise Activity Thermogenesis (EAT):
Calories burned through structured workouts, sports, or physical labor.Thermic Effect of Food (TEF):
Calories used to digest and process food—typically around 10% of total daily calories.
Together, these create your TDEE, the baseline for designing a personalized nutrition and wellness plan.
Special Considerations for GLP-1 Patients
For patients on GLP-1 medications (such as semaglutide or tirzepatide), appetite suppression often leads to reduced calorie intake. While this supports weight loss, it can also impact energy levels and muscle preservation.
Our providers focus on:
Ensuring adequate protein intake (1.2–1.6 g/kg body weight)
Encouraging resistance training to preserve lean muscle
Preventing overly aggressive calorie restriction
Monitoring energy and hormonal markers
Tracking your TDEE helps ensure your metabolism remains supported, not slowed, during medication therapy.
Frequently Asked Questions (FAQ)
A: TDEE stands for Total Daily Energy Expenditure, the total number of calories your body burns each day through all activities and bodily functions.
A: BMR measures the calories burned at complete rest, while TDEE includes activity, exercise, and digestion, making it a more complete daily estimate.
A: A moderate deficit of 500–750 calories per day is common. This typically supports 1–2 lbs of weight loss per week while maintaining muscle and energy.
A: Yes. GLP-1s reduce appetite and food intake, which can lower TDEE if protein and movement aren’t optimized. That’s why provider guidance is key for sustainable progress.
A: Every 4–8 weeks or whenever your activity, medication, or weight changes significantly.
