Understanding Weight Loss Fundamentals and Calorie Basics
Weight loss is simple: burn more calories than you eat. Create a calorie deficit to shed pounds. This means eating fewer calories than your body burns daily.
What is a Calorie Deficit?
A calorie deficit happens when you eat less than your body needs. If your body needs 2000 calories daily, eating 1500 creates a 500-calorie deficit. This deficit makes your body use stored fat for energy.
The Science Behind Weight Loss
Losing weight isn’t just about eating less. It’s about making a plan that works for you. To lose one pound weekly, cut 3,500 calories.
This means reducing 500 calories daily from your current maintenance level. A sustainable plan is key to long-term success.
The Role of Metabolism in Weight Loss
Your metabolism affects how many calories you burn daily. Age, gender, and activity level impact your metabolic rate. Knowing your metabolism helps determine your calorie needs for weight loss.
Activity Level | Calorie Adjustment |
---|---|
Sedentary | -200 calories |
Moderately Active | -300 calories |
Very Active | -400 calories |
Losing 2 pounds weekly needs a big calorie cut. Focus on nutrient-dense foods for proper nutrition. Always talk to a doctor before starting a new diet.

Calculating Your Base Metabolic Rate (BMR)
Your Base Metabolic Rate (BMR) is vital for weight loss. It shows how many calories your body burns at rest. Knowing your BMR helps create an effective plan for fat loss.
The Mifflin-St Jeor Equation
The Mifflin-St Jeor Equation estimates BMR using weight, height, age, and gender. It’s a popular method for this calculation.
- For men: BMR = 10W + 6.25H – 5A + 5
- For women: BMR = 10W + 6.25H – 5A – 161
W is weight in kg, H is height in cm, and A is age in years. This equation determines calories needed to maintain current weight.
The Harris-Benedict Formula
The Harris-Benedict Formula is another way to calculate BMR. It uses the same factors as the Mifflin-St Jeor Equation.
- For men: BMR = 13.397W + 4.799H – 5.677A + 88.362
- For women: BMR = 9.247W + 3.098H – 4.330A + 447.593
