Contrary to early beliefs, drugs like Ozempic's main effect is on GLP-1 receptors in the brain, not the gut. This changes how the brain functions, representing a more intimate and potentially riskier intervention that could trigger psychological side effects or, conversely, treat addiction.
By suppressing appetite, drugs like Ozempic eliminate "comfort eating" as a coping mechanism. This unmasks underlying emotions like sadness or stress, forcing individuals to confront feelings they previously managed with food and develop new emotional regulation strategies.
People adopt fad diets less for nutrition and more to signal a desired identity, class status, or sense of self-control. They fulfill deep psychological needs by allowing adherents to perform a perfected self. One doesn't just 'do' a diet; they 'become' a Paleo or clean eater.
A financial analyst at Barclays predicts the societal impact of new weight loss drugs will be comparable to the smartphone. This suggests they will cause unpredictable and far-reaching shifts in culture, social norms, and industries beyond healthcare, such as food service, dating, and media.
The primary obstacle for fad diets isn't willpower but social friction. Deeply embedded cultural norms around what constitutes a meal and the importance of eating with others make it difficult to sustain restrictive regimens long-term, causing people to abandon them to maintain social connections.
New fad diets are rarely novel; they are reworkings of previous ones. For example, Atkins, Paleo, and Keto all recycle the Victorian-era Banting diet's low-carbohydrate concept. This piggybacking on familiar precepts creates a sense of legitimacy and primes consumers to accept the next iteration.
