Ozempic, Wegovy, and other GLP-1 medications have garnered significant attention, particularly as numerous individuals, including various celebrities, have begun using them for weight management. These drugs are effective in managing Type 2 diabetes and addressing obesity. In a recent video posted on her YouTube channel, television host and actress Oprah Winfrey discussed these medications, her experience with the GLP-1 drug, the importance of recognizing obesity as a disease, and other related topics.

Joining Oprah in this discussion was Dr. Ania Jastreboff, an endocrinologist and associate professor at the Yale School of Medicine. Dr. Jastreboff has dedicated over two decades to researching GLP-1 medications.

Is taking weight loss medications the easy way out?

Dr. Ania stated that it is essential to consider the approach we take when addressing high blood pressure. When patients present with this condition, we advise them on the benefits of a low-salt diet and provide appropriate medications to manage the underlying biological factors. A similar strategy should be applied to obesity. We must emphasize that while a healthy diet and regular exercise are vital for improving overall health and addressing the biological aspects of obesity, there are also medications or surgical options available that can assist in this treatment.

Obesity is a disease

Oprah inquired of Dr. Ania whether obesity should be classified as a disease. Dr. Ania affirmed this classification, emphasizing that obesity is not a matter of personal choice but rather a biological issue. She elaborated that the body regulates energy storage by accumulating fat, a process influenced by hormones that respond to nutrients and communicate signals to the brain regarding hunger, satiety, and energy requirements.

Given this biological regulation, one might wonder why obesity occurs. According to Dr. Ania, the answer lies in our obesogenic environment, characterized by the prevalence of ultra-processed foods, insufficient sleep, limited physical activity, and elevated stress levels. These elements collectively increase the body's propensity to store energy and fat. "Our body is functioning as it is designed to, but it is doing so excessively in this particular environment," she remarked.

What determines obesity vs being overweight?

Currently, there are no definitive definitions available. Traditionally, we have relied on the Body Mass Index (BMI) for this purpose. However, it is important to note that BMI serves primarily as a screening tool and was never intended to function as a diagnostic instrument. Specifically, overweight is classified as a BMI exceeding 25, while obesity is defined as a BMI greater than 30. Initially, these classifications formed the basis for medication indications, but this framework is also undergoing evolution and change.

Why are some people prone to obesity and not others?

According to Dr. Ania, our evolutionary history over centuries and millennia has led us to develop a strong aversion to starvation. She explains, “We consume significantly more than our actual needs. Consequently, our bodies have adapted to burn off the excess. However, in the context of an obesogenic environment, our bodies may respond by storing energy, thinking, ‘Perhaps I will need this later.’ Thus, when we attempt to lose weight, our bodies resist, signaling a refusal to let go.”

When Oprah inquired whether this phenomenon is linked to hormonal influences in her body or in individuals with obesity, the endocrinologist responded, “It could be related to your unique physiology—obesity is classified as a neuro-metabolic disease, where neuroendocrine hormones communicate with the brain. Therefore, your body might be particularly efficient at retaining energy, effectively holding onto extra fat for future use. In contrast, another person's body may not have the same tendency. This variability is influenced by the environment in which we exist.”

Oprah also recounted her enlightening experience upon first using a weight loss medication. She stated, “One realization I had the very first time I took a GLP-1 was that for years, I believed that thin individuals simply possessed greater willpower. I thought they made healthier food choices and could adhere to their diets more effectively, never indulging in a potato chip. However, I came to understand that they are not preoccupied with food; they eat only when hungry and stop when satisfied.”
