Calculating your Total Daily Energy Expenditure (TDEE) is a crucial step in understanding your daily calorie needs, whether you are looking to lose weight, maintain your current weight, or gain muscle. TDEE considers your Basal Metabolic Rate (BMR) and your activity level, and it is important to accurately select your activity level to get an estimate that best matches your daily energy requirements.
Before diving into activity levels, it's important to understand TDEE. Your TDEE represents the total number of calories your body needs to maintain your current weight based on your daily activities. It consists of two main components:
1. Basal Metabolic Rate (BMR): BMR represents the calories your body requires at rest, just to maintain basic functions like breathing and cell repair.
2. Activity Level: This factor takes into account the calories you burn through daily activities, exercise, and other physical efforts.
The tricky part of calculating TDEE is determining your activity level. Here are the common activity levels and a guide to help you choose the right one:
1. Sedentary: If you have a desk job and little to no regular exercise, this level is appropriate. Your daily activity includes minimal movement beyond basic daily activities.
2. Lightly Active: This level is for individuals who have a desk job but engage in light physical activity or exercise a few times a week. Light walking or leisurely cycling falls under this category.
3. Moderately Active: You should select this level if your job involves moderate physical activity, or you engage in structured exercise or sports several times a week. This includes professions like teaching or retail, or regular workouts.
4. Very Active: Choose this level if you have a physically demanding job or engage in strenuous exercise daily. Construction workers, professional athletes, or those with highly active lifestyles belong to this category.
5. Extremely Active: Reserved for elite athletes or individuals with exceptionally strenuous occupations or workouts. This level represents those who engage in heavy training and physical labor.
Here are tips to ensure you choose the right activity level for accurate TDEE calculation:
1. Be honest with yourself: Avoid overestimating your activity level, as this can lead to overestimating your calorie needs, hindering your weight goals.
2. Monitor your progress: If you are not seeing the desired results in terms of weight management, reassess your activity level. It might be necessary to adjust it over time.
3. Consult a professional: If you are uncertain about your activity level or TDEE, consider consulting with a registered dietitian or fitness expert for personalized guidance.
It is important to note that one of the most significant shifts in culture with the COVID-19 pandemic was the way it impacted our physical activity levels. As offices closed their doors and employees transitioned to remote work, the boundaries between work and personal life blurred. Commuting for many people, which once provided an opportunity for physical activity, was eliminated when remote work became permanent. With the office now just a few steps from the bedroom, sedentary workdays became the new norm.
A sedentary lifestyle can have a significant impact on overall activity levels when calculating caloric goals. Here is how it effects the calculations:
Lower Basal Metabolic Rate (BMR): Your BMR is the number of calories your body needs to maintain basic functions at rest. BMR is influenced by factors like age, gender, and body composition. Being sedentary generally means less muscle mass and lower BMR, resulting in a lower calorie starting point for calorie requirements.
Reduced Non-Exercise Activity Thermogenesis (NEAT): Sedentary individuals often engage in fewer spontaneous activities throughout the day. Simple movements like standing, walking, or fidgeting can significantly contribute to daily calorie expenditure. A sedentary lifestyle tends to reduce NEAT, which lowers overall energy expenditure.
Decreased Exercise Activity: Sedentary individuals typically engage in less structured physical activity. This includes activities such as going to the gym, walking, jogging, or playing sports. The lower the frequency and intensity of exercise, the fewer calories are burned through structured activities.
I found that, even with my daily workouts, I was sedentary. That had an impact on my ability to be in a deficit, even restricting calories significantly. My coach switched up my routine. I no longer workout at home and the trip to the gym and navigating the gym has added basic movement to my day. He gave me a daily step goal. Since I work from home, attaining that goal requires intentional walks.
Here are considerations for you to break the sedentary cycle:
1. Schedule Regular Breaks: Set a timer to remind yourself to take short breaks from sitting to stretch and walk around your home or workspace.
2. Workouts: If you do not go to a gym, consider investing in home workout equipment or follow online fitness classes to maintain an active lifestyle from home. If you prefer group workouts or going to the gym, prioritize your workout time and schedule it into your day!
3. Outdoor Activities: Try to spend time outdoors, even if it's just for a short walk. Enjoy nature and fresh air.
4. Prioritize Mental Health: Practice mindfulness and engage in activities that promote mental well-being, such as meditation or yoga.
5. Stay Connected: Find creative ways to stay connected with friends and family, whether through virtual gatherings or safely distanced outdoor activities.
Selecting the appropriate activity level when calculating your TDEE is crucial for tailoring your dietary and fitness goals to your specific needs. Remember that it's not a one-size-fits-all approach, and regular assessments can help you fine-tune your strategy. By taking the time to understand your activity level and making informed choices, you'll be better equipped to achieve your health and fitness objectives.
