How Does Weight Loss Work: Breakthrough Science That Transforms Stubborn Fat

 

How Does Weight Loss Work: A Physician’s Evidence-Based Approach to Real Results

By Dr. Crystal Broussard, MD – Board Certified in Family Medicine, Specialized in Obesity Medicine

Introduction

As a board-certified family physician and aesthetic expert with over twenty years in family medicine and specialized training in obesity medicine, I’m here to clear up the confusion about how does weight loss works.

Weight loss is your body’s process of burning more calories than you take in, which leads to stored fat being used for energy. This process is shaped by your metabolism, hormone levels, and day-to-day habits. Understanding this can feel overwhelming, especially if you’ve tried countless diets without lasting results or faced sudden weight gain despite your best efforts.

Research underscores that interventions targeting weight loss can improve health and prevent obesity-related complications. For many in Spring, TX, battling weight isn’t just about the scale; it’s about reclaiming energy, confidence, and quality of life.

If you’re tired of judgment and want answers that truly fit your journey, you’re in the right place.

How Does Weight Loss Work? (The Science, Simplified)

Weight loss happens when your body uses more energy than it takes in. This is called a calorie deficit. Your metabolism, hormones, and daily habits all play a role in how your body burns calories and stores fat.

In simple terms, weight loss works by:

• Burning more calories than you eat
• Using stored fat for energy
• Adjusting to changes in hormones and metabolism
• Making consistent lifestyle changes

Your metabolism is the process your body uses to turn food into energy. Hormones like insulin, thyroid, and estrogen can speed up or slow down this process. For many women in midlife, hormone shifts can make weight loss feel impossible, even with healthy habits.

In my 20+ years of practice, I’ve seen that many patients don’t just need a diet—they need a medical diagnosis, emotional support, and accountability tools to truly succeed in long-term weight loss. Your body’s biology is powerful, and it’s not your fault if you’ve struggled. Research shows that even small changes, like adding 30 minutes of aerobic exercise each week, can reduce body weight by about half a kilogram.

Calories, Hormones, and Your Metabolism

Calories are the energy in food. If you eat more than you burn, your body stores the extra as fat. But it’s not just about willpower—hormones and metabolism can make this process harder or easier. For example, thyroid problems or menopause can slow metabolism, making weight loss more challenging.

With extensive experience treating patients facing hormonal weight gain, I’ve observed that evaluating and addressing factors such as thyroid function, insulin sensitivity, and estrogen levels can be beneficial for women who feel stuck despite adhering to conventional weight loss strategies.

For many women struggling with the underlying causes of weight gain, identifying and addressing these medical factors is key to long-term success. Learn more about our physician-led obesity care and approaches for treating obesity and weight-related conditions.

The Role of Exercise and Diet

Exercise helps you burn calories and build muscle, which boosts your metabolism. Diet matters too, but it’s not about starving yourself. Balanced meals with protein, fiber, and healthy fats keep you full and support steady energy.

Professional guidelines and systematic reviews confirm that each 30 minutes of weekly aerobic exercise yields measurable weight loss and health improvements. I encourage my patients to start with small, realistic changes—like a daily walk or swapping sugary drinks for water—because these simple shifts add up over time and feel less overwhelming.

When to Seek Medical Attention

If you notice sudden weight gain, unexplained fatigue, or rapid weight loss without trying, it’s time to see a physician. These can be signs of underlying health issues that need prompt attention. In some cases, this may be due to hormone imbalance, metabolic disorders, or conditions like thyroid disease all of which can benefit from hormone optimization or medical evaluation.

Why Is Weight Loss So Hard for Many People?

Losing weight isn’t just about eating less and moving more. Real-life barriers like hormones, stress, and emotional eating can make it feel impossible. Many women, especially in midlife, tell me they feel like their bodies are working against them.

Obesity is linked to higher risks of diabetes, cancer, and heart disease, which adds pressure and fear to the process as detailed in comprehensive medical reviews. But shame and blame don’t help. I want you to know that struggling with weight is common, and it’s not a personal failure. If you are experiencing weight challenges related to midlife or menopause, our EvexiPEL hormone therapy and medically supervised weight loss solutions may offer new hope.

Common Weight Loss Myths

Let’s clear up a few myths:

• Myth: “All calories are equal.”
  Fact: The type of food matters—protein and fiber keep you full longer.
• Myth: “You just need more willpower.”
  Fact: Hormones and stress can override willpower.
• Myth: “Quick fixes work.”
  Fact: Crash diets often lead to regaining more weight later.

Patients often blame themselves for unsuccessful diets, which may not account for their unique biological, psychological, and environmental factors. Science shows that sustainable change not perfection, leads to lasting results.

Real Barriers: Hormones, Stress, and More

Hormonal changes, especially during perimenopause or thyroid shifts, can slow metabolism and increase cravings. Stress raises cortisol, which can trigger emotional eating and fat storage.

From my perspective as a medical weight loss and hormonal health specialist, addressing factors like sleep quality, chronic stress, and hormonal fluctuations is essential, not just what you eat or how much you move. In my clinic, I guide women to focus on small, manageable steps like relaxation techniques and better sleep, because these parts of health are just as impactful as diet and exercise.

What Makes Physician-Led Weight Loss Different?

Physician-led weight loss means you get a plan that’s safe, effective, and tailored to your unique needs. Unlike generic programs, I use medical knowledge to address the root causes of weight gain, like hormones, metabolism, and emotional health.

Research supports that patient-centered, physician-led care delivers better long-term results and supports your overall well-being. I’ve seen firsthand how a personalized approach can help women finally break through stubborn plateaus that resisted conventional diets.

Safety and Medication Management

As a physician, I can safely prescribe and monitor medications like the GLP-1 medical weight loss program (a new type of prescription weight loss injection). These medications, such as semaglutide and tirzepatide injections, can help regulate appetite and blood sugar for those who qualify.

While some providers focus on calorie counting alone, I’ve found that combining medical therapies such as GLP-1s for metabolic reset, with lifestyle support, produces stronger, more sustainable weight loss—especially for women dealing with hormonal or metabolic barriers.

I always make sure any medication fits your health history and goals. My patients appreciate knowing they’re in safe hands, with regular check-ins and support.

Comprehensive, Personalized Plans

Your plan isn’t just about food or exercise. I look at your whole health—hormones, sleep, stress, and even skin confidence. We use tools like body composition scans to track progress, not just the number on the scale. If you’re interested in next-generation solutions that go beyond the basics, explore our non-surgical body sculpting or body fat reduction treatment for comprehensive wellness and body confidence.

My clinical observation is that women often experience the best results when we blend medical treatments, lifestyle coaching, and emotional support, because healing and transformation require a holistic, compassionate approach.

Research-Backed Results: What Actually Works

The best weight loss results come from programs that combine medical guidance, behavioral change, and ongoing support. A large review of 80 studies with over 26,000 participants found that structured interventions, especially those led by physicians, lead to more weight loss and better long-term success.

In my practice, I’ve seen patients who struggled for years finally see progress when we focus on realistic goals and weekly accountability, not just numbers on a scale, but improvements in energy and confidence.

Behavioral Change and Accountability

Changing habits is hard, but you don’t have to do it alone. Regular check-ins, support groups, and tracking tools make a big difference. Research shows that people who have ongoing support are more likely to keep weight off for good, per pooled clinical trial data.

I use weekly visits and digital tracking with my patients to celebrate wins and address challenges as soon as they emerge—this kind of partnership is a major reason why my patients achieve lifelong change.

Medical Advances (GLP-1s, Body Composition Scans)

New treatments like GLP-1 medical weight loss programs (semaglutide, tirzepatide) have changed the game for many women, especially those with metabolic or hormonal challenges. These medications help control hunger and support steady weight loss, as proven in clinical trials.

In my clinical experience, the addition of body composition scans gives us a window into your true progress, seeing fat loss, muscle gains, and water changes so your plan can be adjusted in real time for the best results. I’ve seen women regain their vitality with this integrative, physician-guided model.
