Understanding RMR, BMI, and BMR: Key Health Metrics Explained

When navigating health and fitness, you'll often encounter acronyms like RMR, BMI, and BMR. Each of these metrics offers unique insights into your body's functions and overall health status.

RMR (Resting Metabolic Rate): RMR refers to the amount of energy (in calories) your body requires to maintain basic physiological functions, such as breathing and circulation, while at rest. This measurement is crucial for understanding how many calories your body needs daily to function before additional activities like walking, talking, or eating are factored in.

BMI (Body Mass Index): BMI is widely used to classify weight status and potential health risks. It is calculated by dividing a person's weight in kilograms by the square of their height in meters. BMI categories (underweight, normal weight, overweight, and obese) help identify potential health risks related to weight issues, but it does not measure body fat directly or distribute between muscle and fat.

BMR (Basal Metabolic Rate): BMR is very similar to RMR and is often used interchangeably. However, BMR is a more controlled measurement that estimates the minimum amount of energy needed for basic functions at complete rest in a neutral environment after waking. It does not include calories burned during digestion or physical activity.

Understanding these metrics can help tailor diet and exercise plans effectively. For instance, knowing your RMR or BMR can guide nutritional decisions to achieve weight loss or muscle gain goals, while BMI can provide a quick snapshot of potential health risks associated with body weight.

However, it's important to combine these metrics with other assessments for a comprehensive health evaluation, as BMI alone can be misleading due to its inability to differentiate between muscle mass and fat.

Should I Do Cardio Before or After Weightlifting?

A very common question - should you do cardio before or after your weight lifting session?

Cardio Before Weights: Doing cardio before lifting weights is beneficial if your primary goal is to increase your cardiovascular endurance or warm up your muscles to prevent injury during strength training. However, it's important to keep the cardio session light and short to conserve energy for lifting weights. Extended or intense cardio sessions before weights might deplete your energy reserves, potentially reducing your strength and effectiveness during the weight-lifting session.

Cardio After Weights: If your main focus is on building strength or muscle mass, it's generally better to perform cardio after your weight training session. Lifting weights first allows you to approach your strength training with maximum energy and concentration, which is crucial for achieving the best results in muscle development. Following up with cardio can help in burning fat and enhancing muscle definition, as your body may utilize fat stores for energy once the glycogen stores are depleted from weight lifting.

How Probiotics Work

Probiotics are often called "good" bacteria because they help maintain the health of your gut. They are live microorganisms, similar to the beneficial microorganisms found naturally in your digestive system.

Probiotics support your body's ability to absorb nutrients and fight infection. They are believed to restore the natural balance of gut bacteria that can be disrupted by poor diet, stress, or antibiotics. By enhancing the gut flora, probiotics play a crucial role in maintaining gut health.

Benefits of Probiotics:

1. Digestive Health: Probiotics can help prevent or treat digestive issues like irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diarrhea caused by infections or antibiotics.

2. Immune Function: They can boost your immune system by increasing the production of immune cells in the gut.

3. Mental Health: Emerging research suggests a link between gut health and mood and mental health. This connection is often referred to as the "gut-brain axis."

It’s important to note that while probiotics are generally safe for most people, their effects can vary.
