Willpower Does Not Equal Weight Loss

By: Dr. Alexa

“Just Eat Less and Move More.”

For decades, weight loss advice has revolved around one central principle: eat fewer calories than you burn, and the weight will come off. This concept — known as a caloric deficit — is rooted in the laws of thermodynamics and is biologically accurate on paper to some extent.

So why is it that many people track every bite, reduce their intake, and exercise regularly — yet still struggle to lose weight?

Here’s the truth: caloric deficit is necessary for fat loss, but it doesn’t guarantee visible weight loss, if stress and inflammation is not addressed first. Most of us are not metabolically healthy enough for us to achieve long term weight loss.

Chronic Dieting Actually Slows Your Metabolism

As you diet, your body becomes more efficient — it burns fewer calories to perform the same functions. This is a protective response to perceived starvation.

• Your basal metabolic rate (BMR) drops burning less calories at rest.

• Non-exercise activity thermogenesis (NEAT) decreases (you unconsciously move less).

• Hunger hormones increase, making you crave more food.

Over time, the deficit you started with may shrink or disappear altogether unless you adjust.

Connecting the Dots Between Stress, Inflammation, & Fat Loss

Chronically elevated cortisol levels can interfere with weight loss in several ways:

Fat Storage

• high cortisol promotes visceral fat storage — the kind that accumulates around your organs and midsection. This type of fat is more resistant to loss.

Insulin Resistance

• long-term elevated cortisol can increase insulin resistance, making it harder to access stored fat for energy and potentially leading to more fat gain.

Muscle Breakdown

• cortisol can increase the breakdown of muscle tissue, which lowers your resting metabolic rate over time, making it harder to burn calories.

Disrupted Sleep

• High cortisol can interfere with sleep quality or cause insomnia. Poor sleep disrupts hunger hormones (ghrelin and leptin) and reduces your body’s ability to regulate weight.

Stubborn Weight or Chronic Inflammation?

Disrupted Mitochondrial Function

• Inflammation impairs mitochondria (the cell’s energy factories), reducing your body’s ability to efficiently burn calories and fat for energy.

Inflammation Induced Slowed Metabolism

• Inflammatory cytokines (like TNF-alpha and IL-6) can interfere with thyroid function and other hormones that regulate metabolic rate, slowing down how many calories you burn at rest.

Insulin Resistance (Part 2)

• Chronic inflammation — especially in fat tissue — promotes insulin resistance just like cortisol, which makes it harder for your body to use glucose for energy. As a result:

• Blood sugar stays high.

• The body stores more fat, particularly around the abdomen.

• Fat burning is impaired.

AND FINALLY, What You Can Do About It

✅ How to Lower Inflammation and Cortisol to Support Weight Loss

• Eat an anti-inflammatory diet: focus on whole foods, omega-3s (like fish and flax), leafy greens, berries, olive oil, and turmeric.

• Avoid ultra-processed foods, sugar, refined carbs, and industrial seed oils.

• Get quality sleep and manage stress.

• Move regularly, even light activity helps.

• Get Tested: Find the underlying causes of cortisol and inflammation through functional lab testing. With proper testing, we can see what your unique stressors are. 

• Support gut health with fiber, fermented foods, or a probiotic if needed.

• Address underlying health issues with a functional root cause healthcare provider. 

Final Thoughts

Chronic stress and inflammation creates a hormonal and metabolic environment that favors fat storage and hunger, not fat loss. While calories still matter, lowering inflammation and cortisol can unlock your body’s natural ability to lose weight by restoring hormonal balance, improving insulin sensitivity, and boosting energy.
