Calorie deficit to lose 3 pounds a week: Diet Guide
Introduction
To embark on a successful weight loss journey, it's crucial to understand the fundamental concept of a calorie deficit. The key principle is that to lose one pound of fat, you need to create a calorie deficit of approximately 3500 calories. Extrapolating this to a weekly goal of shedding 3 pounds, the target calorie deficit becomes 10,500 calories per week. This translates to an average daily calorie deficit of 10500 / 7 = 1500 calories.
| Weekly Target (3 Pounds) | Daily Calorie Deficit |
|---|---|
| 10,500 calories | 1,500 calories |

Introduction to Calorie Deficit
Calorie deficit is the foundation of effective weight loss. It occurs when you consume fewer calories than your body expends, forcing it to tap into stored fat for energy. Understanding this concept is essential for achieving your weight loss goals.

BMR (Basal Metabolic Rate) and TDEE
Your Basal Metabolic Rate (BMR) is the amount of calories your body requires at rest to maintain essential physiological functions. It represents the energy expended in a neutral temperature environment during periods of no physical activity. BMR serves as a foundational benchmark for determining your overall calorie needs. To calculate Total Daily Energy Expenditure (TDEE), we multiply the BMR values by a factor corresponding to the individual's physical activity level. The table below illustrates the values of this activity factor, ranging from no activity to high-intensity activity:Physical Activity Factors for TDEE Calculation Activity Level Factor No Activity (Sedentary) 1.2 Light Activity (Light exercise/sports 1-3 days/week) 1.375 Moderate Activity (Moderate exercise/sports 3-5 days/week) 1.55 High Activity (Hard exercise/sports 6-7 days a week) 1.725 Very High Activity (Very hard exercise/sports & physical job or 2x training) 1.9 BMR and TDEE can be calculated using factors such as weight, height, biological gender, and activity level. For a quick calculation, you can use our online BMR/TDEE calculator. For a detailed illustration, consider the following example in the table below, illustrating a BMR calculation:
Understanding BMR is essential as it forms the basis for calculating Total Daily Energy Expenditure (TDEE), which accounts for your daily activity level.BMR TDEE Calculation Example Biological Gender Age Weight (lbs) Height (inches) Activity Factor BMR Male 30 165 70 1.55 (Moderate Activity) 2700 calories/day TDEE and BMR Relation with Calorie Deficit
Let's figure out how many calories you should eat each day to lose 3 pounds a week:
- Your BMR is 2700 calories/day (based on our example).
- Your Activity Factor is 1.55 (considered Moderate Activity).
Calculate your Total Daily Energy Expenditure (TDEE) by multiplying BMR and Activity Factor:
\[ TDEE = 2700 \times 1.55 = 4185 \text{ calories/day} \]
To create a 1500 calorie deficit, subtract 1500 from the TDEE:
\[ Caloric Intake = TDEE - 1500 = 4185 - 1500 = 2685 (calories/day} \]
Therefore, to lose 3 pounds a week, aim for a daily intake of 2685 calories. This involves consuming 2685 calories per day, factoring in your BMR and activity level.
Summary:
To determine how many calories you need to eat per day to lose 3 pounds a week, you can use our TDEE-BMR calculator. Simply input your details, and once you get the result, subtract 1500 calories.

- Fruits such as berries, apples, and oranges
Good Sources of Protein:
Ensure your protein intake comes from quality sources, including:
- Lean meats like chicken, turkey, and fish
- Eggs and dairy products
- Plant-based proteins such as tofu, tempeh, and legumes
Good Sources of Healthy Fats:
Incorporate healthy fats into your diet from sources like:
- Avocado
- Nuts and seeds
- Olive oil
- Fatty fish like salmon and mackerel
Understanding Omega-3 and Omega-6:
Omega-3: Found in fatty fish, chia seeds, flaxseeds, and walnuts, omega-3 fatty acids contribute to heart health, reduce inflammation, and support brain function. Including these sources in your diet promotes overall well-being.
Omega-6: Commonly found in vegetable oils and nuts, omega-6 fatty acids are crucial for cell function and growth. However, maintaining a balance between omega-3 and omega-6 intake is important for optimal health.
