Why You Can't Lose Weight - And It's Not Your Fault

Have you been trying to lose weight for a significant period of time without success? Have you tried every diet in the book? You’re not alone. Millions of people around the globe spend significant time and resources trying to lose weight - and still fail. 

Based on our medical experience here at Inspire Medical and Wellness, we’ve identified 4 common reasons for unexpected weight gain. 

Thyroid dysfunction

The thyroid gland, part of the body’s endocrine system, regulates hormone levels. These hormones tell different parts of the body what to do and how to do it. When functioning improperly, the thyroid produces less-than-optimal levels of hormones, sending the body inaccurate instructions on how to operate. As the thyroid regulates metabolism, thyroid dysfunction can lead to weight gain and may also make it difficult to lose weight.


Stress largely contributes to weight gain and inability to lose weight because it activates the production of the stress hormone, cortisol. Cortisol causes what is commonly known as the “fight or flight” response in the human body, a state of slowed digestion and increased blood sugar supply. This immediate supply of energy in the body increases hunger, however the body never expends the extra energy, leaving it stored as fat. 

Menopause & hypogonadism

As we age, our bodies naturally undergo hormonal and physiological changes that impact our ability to maintain a healthy weight. For women, this natural process is known as menopause, while in men this process is called hypogonadism. During this period, both men and women become more susceptible to weight gain due to changes in estrogen and testosterone levels

Sleep deprivation

How many hours of sleep do you get every night? Do you have a regular sleep schedule? These questions may seem irrelevant to weight management, however, sleep quality can significantly impact an individual’s ability to maintain a healthy weight. In fact, those who consistently sleep fewer than the recommended 7-9 hours per night are much more likely to gain weight or become obese than those who consistently get a full night’s sleep. 

How does sleep impact weight? When we don’t get enough sleep, our bodies are left feeling fatigued and low on energy. The body, in an effort to restore energy levels, responds by increasing ghrelin levels and decreasing leptin levels, effectively increasing appetite. Furthermore, the body doesn’t just want more food when it’s tired, it wants more energy-dense food. Yes, you got it...carbs, sugar, and fat. Over the course of time, sleep deprivation and the resulting eating habits can significantly impact your overall health and your waistline.
