Comprehensive Guide to Weight Loss Terms

BMI (Body Mass Index)

A measure that uses height and weight to estimate body fat. It’s a common screening tool to categorize individuals into weight categories that may lead to health problems.

Calculation

BMI is calculated by dividing a person’s weight in kilograms by the square of their height in meters.

Categories
  • Underweight: BMI < 18.5
  • Normal weight: BMI 18.5–24.9
  • Overweight: BMI 25–29.9
  • Obesity: BMI 30 or greater

“BMI is a simple, inexpensive, and noninvasive surrogate measure of body fat.” – National Institute of Health

Ketogenic Diet

A high-fat, low-carbohydrate diet that shifts the body’s metabolism towards ketosis, a state where fat is burned for energy instead of carbohydrates.

How it Works

By drastically reducing carbohydrate intake and replacing it with fat, the body enters a metabolic state called ketosis.

Benefits
  • Weight loss
  • Improved mental clarity
  • Increased energy

“The keto diet can be a great way to lose weight and improve health.” – Harvard Medical School

Intermittent Fasting

An eating pattern that cycles between periods of eating and fasting. It can help with weight loss by reducing calorie intake and improving metabolic health.

Methods

Common methods include the 16/8 method, Eat-Stop-Eat, and the 5:2 diet.

Advantages
  • Weight loss
  • Improved insulin sensitivity
  • Reduced inflammation

“Intermittent fasting can be a powerful tool for weight loss and longevity.” – Mayo Clinic

Gastric Bypass Surgery

A surgical procedure for weight loss where the stomach is divided into a small upper pouch and a larger lower pouch, and the small intestine is rearranged to connect to both. This reduces the amount of food you can eat and the calories absorbed.

Procedure

The surgery involves creating a small stomach pouch and bypassing a portion of the small intestine.

Risks
  • Infection
  • Blood clots
  • Dumping syndrome

“Gastric bypass surgery can be life-changing but comes with significant risks.” – American Society for Metabolic and Bariatric Surgery

Metabolism

The process by which your body converts what you eat and drink into energy. A higher metabolism means more calories burned, which can aid in weight loss.

Factors

Metabolism is influenced by age, sex, muscle mass, and physical activity levels.

Boosting Metabolism
  • Exercise regularly
  • Eat protein-rich foods
  • Stay hydrated

“A healthy metabolism is crucial for maintaining a healthy weight.” – Centers for Disease Control and Prevention
