Join me as we embark on a thrilling adventure, simplifying the complex and revealing the secrets to fueling your body just right. Are you ready to discover the power of calories and macros? Let’s dive in together and conquer this nutritional quest!
What are Calories?
Calories are units of energy that your body needs to work and stay busy. They give your body energy, just like oil gives a car energy. Calories come from everything you eat and drink during the day.
To stay at a healthy weight, you should eat about the same number of calories as you burn through physical exercise and basic body functions. The term for this balance is “energy balance.”
Factors influencing daily calorie needs
Several factors influence how many calories you need each day. These factors determine the amount of energy your body requires to function properly. Let’s explore them together!
Basal Metabolic Rate (BMR)
Your basal metabolic rate (BMR) plays a significant role. BMR refers to the calories your body needs at rest to maintain vital functions like breathing and circulating blood. Although you can’t change your BMR easily, you can consider it when determining your calorie needs.
Calculating your Basal Metabolic Rate (BMR) helps determine the number of calories your body needs to perform essential functions at rest. Here’s a simple way to estimate your BMR using the Harris-Benedict equation:
For males:
BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) – (5.677 × age in years)
For females:
BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) – (4.330 × age in years)
To use the equation, follow these steps:
- Convert your weight from pounds to kilograms by dividing it by 2.205. For example, if you weigh 150 pounds, divide 150 by 2.205 to get approximately 68 kg.
- Convert your height from inches to centimeters by multiplying it by 2.54. For example, if you are 65 inches tall, multiply 65 by 2.54 to get approximately 165 cm.
- Substitute the converted weight, height, and age into the appropriate equation based on your gender.
- Calculate the equation to find your estimated BMR.
Physical activity level
Your physical activity level affects calorie requirements. If you engage in regular exercise or have an active lifestyle, you’ll need more calories to fuel your activities. Being active boosts your metabolism and burns additional calories.
Calculating your physical activity level is a straightforward process. Here’s a simple method to determine it:
Sedentary: If your daily routine involves mostly sitting or minimal physical activity, such as working at a desk job or watching TV for most of the day, you fall into the sedentary category. No additional exercise or structured physical activity is included in this level.
Lightly Active: If you engage in light physical activity for about 1-3 days per week, you can be considered lightly active. This includes activities like casual walking, light house chores, or occasional recreational activities.
Moderately Active: If you exercise or engage in moderate physical activity for about 3-5 days per week, you would fall into the moderately active category. Examples of moderate activities include brisk walking, cycling, swimming, or participating in a fitness class.
Very Active: If you have a physically demanding job or participate in intense exercise or sports for about 6-7 days per week, you would be classified as very active. This level includes activities like running, weightlifting, high-intensity interval training (HIIT), or engaging in competitive sports.
It’s important to be honest with yourself when determining your activity level. Consider the overall intensity and frequency of your physical activities throughout a typical week. Remember, the goal is to assess your regular physical activity, excluding any sporadic or infrequent events.
Calculating your physical activity level helps in estimating your daily calorie needs more accurately. The more active you are, the more calories your body requires to support your energy expenditure. Taking this into account alongside your basal metabolic rate (BMR) can provide a clearer picture of your total calorie requirements.
Thermic effect of food (TEF)
The thermic effect of food (TEF) influences calorie needs. When you eat, your body expends energy to digest, absorb, and process the nutrients. Protein, for example, has a higher TEF compared to carbohydrates and fats. Including protein in your meals can increase calorie burn.
Calculating the thermic effect of food (TEF) is relatively simple. Here’s how you can estimate it:
Determine your total daily calorie intake: Start by calculating the number of calories you consume in a day. You can track your food and beverage intake using a mobile app or a food diary.
Calculate the TEF percentage: On average, the TEF accounts for about 10% of your total calorie intake. Multiply your total daily calorie intake by 0.1 (10%) to find the estimated TEF.
Calculate the TEF in calories: Multiply the TEF percentage by your total daily calorie intake. This will give you the estimated TEF in calories.
For example, if your daily calorie intake is 2000 calories, you would multiply 2000 by 0.1 to get 200 calories as the estimated TEF.
It’s important to note that the TEF can vary based on factors such as the composition of your diet. Protein has a higher thermic effect compared to carbohydrates and fats. So, if you consume a higher protein diet, the TEF may be slightly higher.
What are Macronutrients (Macros)?
Macronutrients, also known as “macros,” are the essential nutrients that our bodies need in larger quantities to stay healthy and strong. There are three main types of macros: carbohydrates, proteins, and fats. Let’s dive into what each of these macros does for you!
Carbohydrates are like your body’s fuel. They give you energy to play, run, and learn new things. Foods like bread, rice, pasta, and fruits are packed with carbohydrates. It’s a good idea to choose whole grains and fruits for their extra nutrients and fiber.
Proteins are your body’s building blocks. They help you grow taller, make your muscles strong, and repair any boo-boos. Foods like chicken, fish, eggs, beans, and nuts are excellent sources of protein. Try to have a little protein with each meal or snack.
Fats are not all bad! Some fats are actually good for you and help your body work properly. Avocados, nuts, and olive oil are examples of healthy fats. They help your brain grow and keep your skin nice and soft. But be careful, some fats, like those in chips and cookies, are not as good for you. It’s best to enjoy those as treats sometimes.
Determining Your Macros
To achieve your health goals, it’s important to understand your macronutrients (macros): carbohydrates, proteins, and fats. Determining the right balance of macros for you is crucial. Here’s how you can do it:
Assess Your Needs: Consider your activity level, body composition goals, and overall health. This will help you determine your macro ratios.
Protein: Ensure you’re getting enough protein to support muscle growth and repair. Aim for lean sources like chicken, fish, and beans. A general recommendation is 0.8 grams of protein per kilogram of body weight.
Carbohydrates: Determine your carbohydrate intake based on your energy needs. Focus on whole grains, fruits, and vegetables. They provide essential vitamins, minerals, and fiber. Avoid sugary drinks and processed snacks.
Fats: Include healthy fats like avocados, nuts, and olive oil in your diet. They promote heart health and help absorb vitamins. Limit saturated and trans fats found in fried and processed foods.
Remember, individual needs vary, so it’s essential to listen to your body. Consult a registered dietitian or nutritionist for personalized guidance. Tracking your macros using apps or journals can also help you stay on track.
