Why Am I Not Losing Weight? 5 Medical Factors That Could Be Holding You Back

At HealthStone Primary Care Partners in Hollywood, FL, we know how frustrating it is to feel stuck on your weight loss journey. 

You eat well and stay active, yet the scale refuses to budge. Dr. Charles Stone and our primary care team help patients uncover the hidden biological roadblocks that stall progress.

If you are struggling to manage your weight, a medical evaluation can provide the answers you need. We offer personalized weight loss support to help you reach your goals safely.

1. An underactive thyroid

An underactive thyroid, or hypothyroidism, can slow your metabolism, but it may not cause as much fat gain as you think. According to the American Thyroid Association, an underactive thyroid typically causes a modest weight gain of about 5 to 10 pounds.

This weight gain is mostly due to salt and water retention in your tissues, not actual fat. Once you treat the underlying cause, your body's ability to lose weight returns to normal. At our Hollywood, FL office, we can run simple blood tests during your annual physicals to check your thyroid levels.

2. Certain prescription medications

Some daily medications can act as biological roadblocks that actively trigger weight gain or stall your progress. A 2025 systematic review in Schizophrenia Bulletin found that certain prescription drugs, like beta-blockers, are causally linked to weight gain. 

These medications can alter brain pathways, increasing your appetite or slightly lowering your resting energy expenditure. You should never stop taking a prescribed medication without talking to your doctor first. We offer comprehensive medication reviews to see if we can safely transition you to more weight-neutral alternatives.

3. Chronic sleep deprivation

Not getting enough sleep directly disrupts the hormones that control how hungry you feel throughout the day. In a 2022 randomized clinical trial of adults with overweight, restorative sleep was linked to eating fewer daily calories.

Adequate sleep keeps your hunger hormones, ghrelin and leptin, in a healthy balance. When you are sleep-deprived, your brain demands quick energy, leading to intense cravings for high-calorie foods. 

Our team works with you on lifestyle adjustments to help improve your sleep hygiene and support your overall wellness.

4. Subconscious calorie creep

Even when you are trying your best to eat healthy, it's easy to underestimate how many calories you actually consume. A study in the American Journal of Clinical Nutrition found that successful weight loss maintainers underreported their daily intake by a median of 605 calories. 

This tracking discrepancy may be a natural result of dieting fatigue. Over time, we subconsciously overlook small snacks, cooking oils, or liquid calories that can completely erase a caloric deficit. 

Our team provides personalized nutritional guidance as part of our wellness and preventive care services to help you build sustainable habits.

5. High stress and emotional eating

Chronic stress does not shut down your metabolism, but it heavily influences the behaviors that lead to weight gain. A 2025 systematic review in Nutrients highlights that stress is strongly linked to emotional eating and consuming high-calorie foods.

When you are stressed, your body releases hormones that drive cravings for comfort foods. Managing your stress is key to regaining control over your dietary choices. We take a holistic approach to your health, helping you manage stress and its impact on your physical well-being.
