Are You Trying, and Failing, To Lose Weight?

If you’ve struggled to lose weight, you’re not alone. More importantly, struggling with weight is not simply a matter of willpower or personal discipline. Obesity is now recognized as a chronic, complex medical condition influenced by genetics, hormones, metabolism, sleep, medications, environment, and lifestyle. This epidemic iis likely a function of our diets being inundated with ultraprocessed food and iit being easier to lead a sedentary lifestyle. Understanding this can help people move beyond self-blame and focus on effective, evidence-based solutions.

One of the best books I’ve found on this topic is Nature Wants Us to Be Fat by Richard J. Johnson, MD. I frequently recommend it because it helps explain the biology behind weight gain and why so many people find it difficult to lose weight despite their best efforts.

Today, more than 40% of U.S. adults have obesity, and rates have steadily increased over the past two decades. This growing epidemic highlights that the problem is far more complex than simply “eating too much” or “not exercising enough.”

Start by Looking for Medical Causes

Before beginning any weight-loss program, it’s important to determine whether there are underlying medical conditions making weight loss more difficult. These may include:

• Obstructive sleep apnea
• Hypothyroidism
• Iron deficiency or anemia
• Vitamin and nutritional deficiencies
• Menopause and other hormonal changes
• Low testosterone in some men
• Chronic stress and poor sleep

In addition, many commonly prescribed medications can contribute to weight gain or make weight loss more challenging. These include certain antidepressants, steroids, medications for diabetes, and some acid-reducing medications, among others.

Without identifying and addressing these factors, even the most disciplined diet and exercise program may produce disappointing results.

Exercise Matters—but It’s Only Part of the Equation

Physical activity is essential for overall health and plays an important role in maintaining weight loss. However, exercise alone is rarely enough to produce substantial weight loss.

Building and maintaining muscle is particularly important because muscle tissue burns more calories than fat, even at rest. As we age—or after prolonged inactivity or illness—we naturally lose muscle mass, causing our metabolism to slow. This helps explain why some people honestly report eating very little yet still struggle to lose weight.

Strength training combined with regular aerobic activity can help preserve muscle mass and improve metabolic health.

Understanding Insulin Resistance

For many people, excess weight is closely linked to insulin resistance.

Insulin is a hormone that regulates blood sugar, but it also promotes fat storage and makes it more difficult for the body to access stored fat for energy. Over time, diets high in refined carbohydrates and added sugars can worsen insulin resistance in susceptible individuals.

When insulin resistance improves, many patients find that losing weight becomes significantly easier.

Nutrition Still Matters

Successful long-term weight management isn’t about following the latest fad diet. Instead, most people benefit from:

• Reducing added sugars and refined carbohydrates
• Eating adequate protein to preserve muscle
• Choosing whole, minimally processed foods
• Increasing fiber intake
• Paying attention to portion sizes
• Developing eating patterns that are sustainable over time

For some individuals, intermittent fasting or time-restricted eating may also be helpful. While these approaches are not appropriate for everyone, they can improve insulin sensitivity and reduce overall calorie intake when used safely under medical guidance.

Modern Medications Are Changing the Landscape

One of the most significant advances in obesity treatment has been the development of GLP-1 receptor agonists and newer dual hormone medications.

Medications such as semaglutide (Ozempic® and Wegovy®) and tirzepatide (Mounjaro® and Zepbound®) help regulate appetite, improve insulin resistance, slow stomach emptying, and reduce what many patients describe as “food noise”—the constant thoughts about food that can make weight management exhausting.

These medications are not a substitute for healthy lifestyle habits, but for carefully selected patients they can be remarkably effective when combined with nutritional counseling, exercise, and treatment of underlying medical conditions.

There Is Hope

The most important message is this: if you’ve struggled with your weight for years, don’t assume you have failed.

Weight management is rarely about a lack of motivation. More often, it requires identifying and treating the biological, hormonal, and lifestyle factors that make weight loss difficult.

With a thorough medical evaluation, an individualized nutrition plan, regular physical activity, and—when appropriate—modern medications, many people are finally able to achieve meaningful, lasting weight loss.

You don’t have to face this challenge alone. Partner with a physician who understands the science of obesity and is willing to work with you to develop a comprehensive treatment plan. Lasting success is possible, and there are more effective tools available today than ever before.
