The Science of Weight Loss: What Works and Why

People everywhere, including on the Central Coast, are interested in weight loss. The weight loss industry is filled with myths and misconceptions. At Headstrong Fit, we focus on understanding the science of weight loss for sustainable, healthy living.


Calories: The Basics

Weight loss is a simple equation: calories in vs. calories out. Burning more calories than you consume results in weight loss, known as a caloric deficit.

Basal Metabolic Rate (BMR): Calories needed at rest, accounting for about 60-75% of daily needs.

Physical Activity: Exercise and daily activities increase calorie burn.

Digestion: Energy used for digesting food, about 10% of daily calories.


Macronutrients and Weight Loss

Proteins: Essential for muscle repair and growth, can increase calorie burn and reduce appetite.

Fats: Healthy fats support hormonal balance and satiety, reducing caloric intake.

Carbohydrates: The body's primary energy source; complex carbs provide sustained energy.


The Role of Exercise

Diet is critical, but exercise is also essential. Aerobic exercises burn fat, while resistance training builds muscle, boosting metabolism.


Myth Busting

  • Starvation Mode: Eating too few calories doesn't trigger "starvation mode," but prolonged calorie restriction can slow metabolism.
  • Spot Reduction: You can't target specific areas for weight loss; fat loss occurs overall.
  • Fad Diets: Quick fixes rarely yield lasting results; a balanced approach is better.


Psychological Aspect

Weight loss is a mental journey. Realistic goals, support, stress management, and sleep are vital for success.
