How Many Calories to Maintain Your Weight by Body Size
Understand TDEE and find out how many calories are needed to maintain weights of 165, 190, 240, and 250 lbs.
How Many Calories to Maintain Your Weight by Body Size
To lose or gain weight, you must first know how to stay exactly where you are. Your maintenance calories—also known as your Total Daily Energy Expenditure (TDEE)—vary significantly based on your body size, gender, and activity levels. In this guide, we will analyze the energy requirements for various weight categories, looking specifically at how many calories to maintain 250 lbs, how many calories to maintain 190 lbs, how many calories to maintain 240 lbs, and how many calories to maintain 165 lbs.
What Determines Your Maintenance Calories?
Your TDEE is made up of four main components:
- Basal Metabolic Rate (BMR): The energy your body needs to survive at rest (heart beating, breathing, brain function). Larger bodies require more energy to sustain basic functions.
- Non-Exercise Activity Thermogenesis (NEAT): Energy burned during daily movement like fidgeting, walking, and chores.
- Thermic Effect of Food (TEF): The energy required to digest food (about 10% of total calories).
- Exercise Activity Thermogenesis (EAT): The energy burned during structured workouts.
Maintenance Estimates by Body Weight
Below are estimated daily maintenance calories for adult men and women at different weights, assuming a height of 5’10” (men), 5’5” (women), and moderate daily activity.
1. How Many Calories to Maintain 250 lbs
A body weight of 250 lbs requires significant energy to maintain due to the metabolic demands of carrying larger mass.
- Male (Moderate Activity): ~3,100 to 3,400 calories/day
- Female (Moderate Activity): ~2,600 to 2,900 calories/day
2. How Many Calories to Maintain 240 lbs
Very similar to 250 lbs, a 240 lb individual has a high baseline metabolic rate.
- Male (Moderate Activity): ~3,000 to 3,300 calories/day
- Female (Moderate Activity): ~2,500 to 2,800 calories/day
3. How Many Calories to Maintain 190 lbs
This represents a common average weight category for adult males.
- Male (Moderate Activity): ~2,600 to 2,800 calories/day
- Female (Moderate Activity): ~2,100 to 2,300 calories/day
4. How Many Calories to Maintain 165 lbs
At 165 lbs, the energy requirements are lower, making calorie deficits tighter to calculate.
- Male (Moderate Activity): ~2,300 to 2,500 calories/day
- Female (Moderate Activity): ~1,900 to 2,100 calories/day
Maintenance Calorie Comparison Table
Below is a quick reference table showing how weight and activity level impact maintenance needs (estimates for an adult male, 30 years old, 5’10”):
| Body Weight | Sedentary | Lightly Active | Moderately Active | Very Active |
|---|---|---|---|---|
| 165 lbs | 2,000 kcal | 2,300 kcal | 2,500 kcal | 2,800 kcal |
| 190 lbs | 2,200 kcal | 2,500 kcal | 2,750 kcal | 3,100 kcal |
| 240 lbs | 2,500 kcal | 2,850 kcal | 3,150 kcal | 3,550 kcal |
| 250 lbs | 2,600 kcal | 2,950 kcal | 3,250 kcal | 3,650 kcal |
How to Calculate Your Exact Maintenance Calories
While tables provide general ranges, you can calculate your TDEE using the Mifflin-St Jeor formula:
$$\text{BMR (Men)} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} - 5 \times \text{age (y)} + 5$$ $$\text{BMR (Women)} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} - 5 \times \text{age (y)} - 161$$
Once you have your BMR, multiply it by your activity multiplier:
- Sedentary: BMR × 1.2
- Lightly Active: BMR × 1.375
- Moderately Active: BMR × 1.55
- Very Active: BMR × 1.725
