Basal metabolic rate is the amount of energy per unit of time that a person needs to keep the body functioning at rest. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles.
How do you use your BMR to lose weight?
Your Basal Metabolic Rate (BMR) is the number of calories you burn at rest. The safest way to handle a caloric reduction for fat loss is to reduce your intake by something marginal and being consistent. To optimize your BMR for lean body mass gain, you need to exceed the number of calories you require each day.
Is it OK to eat under your BMR?
Should you eat less than your BMR to lose weight? Since BMR represents the minimal calorie number you need for involuntary body functions, you shouldn’t consume fewer calories than your BMR. To lose weight properly, you need to consider both physical activity and your BMR.
How does basal metabolic rate affect energy balance?
The basal metabolic rate accounts for most of our energy needs, about 60-75% of total energy expenditure. … Higher BMR levels result from greater levels of lean body mass. Since males tend to have more lean body mass than women, their BMR is generally higher. BMR can also decrease with age as lean body mass decreases.
What happens if I eat less than my BMR?
1. It Can Lower Your Metabolism. Regularly eating fewer calories than your body needs can cause your metabolism to slow down.
What is a good BMR?

What happens if you eat less than 1000 calories?
In general, if you cut 500 to 1,000 calories a day from your typical diet, you’ll lose about 1 pound (0.5 kilogram) a week. It sounds simple. However, it’s more complex because when you lose weight, you usually lose a combination of fat, lean tissue and water.
What happens when BMR increases?
Environmental temperature – if temperature is very low or very high, the body has to work harder to maintain its normal body temperature, which increases the BMR. Infection or illness – BMR increases because the body has to work harder to build new tissues and to create an immune response.
What is the difference between basal metabolic rate and resting metabolic rate?
Basal metabolic rate (BMR) is often used interchangeably with resting metabolic rate (RMR). While BMR is a minimum number of calories required for basic functions at rest, RMR — also called resting energy expenditure (REE) — is the number of calories that your body burns while it’s at rest.
What does it mean to have a low basal metabolic rate?
A low BMR means you have to eat less calories in order to lose body fat and weight. The Metabolic age is calculated by comparing your Basal Metabolic Rate to the average BMR of your chronological age group. If your metabolic age is higher than your actual age, it’s an sign that you need to improve your metabolic rate.
Do you eat less than your BMR to lose weight?
Eat fewer calories than you burn each day.
Keep in mind that your body burns calories all day long as part of your basal metabolic rate (BMR), because it takes energy (calories) for your body to perform basic functions that are necessary for life—breathing, digesting, circulating, thinking and more.
Is 1200 calories too low?
A 1,200-calorie diet is much too low for most people and can result in negative side effects like dizziness, extreme hunger, nausea, micronutrient deficiencies, fatigue, headaches, and gallstones ( 23 ).
