Part of what makes GLPs so powerful is that they can alter behavior before a person ever reaches conscious contemplation. Many people never meaningfully consider a different way of eating or living because they have never experienced the physiological and psychological conditions that make that alternative feel preferable. GLPs can change the reward landscape first, and cognition often catches up afterward.
For some people, cognition never catches up to the behavioral shift, which is why many revert after discontinuation. But that outcome is not inevitable. The period on a GLP can become evidence—>if someone consciously updates the perceived benefits of food, movement, satiety, and their old habits, the new behavior can become genuinely preferable rather than merely pharmacologically easier.
Obesity is driven by a number of interacting factors that all converge to affect its proximal cause: chronic energy surplus.
Beliefs, priorities, and preferences are the biggest factors. Most people simply have no desire to be healthy or to put in the effort required to be healthy in the modern environment.
And appreciating this truth and the agency that people possess is not mutually exclusive with everything else that follows.
Hyperpalatable food supply is next, defined by food options rich in combinations of added sugars, refined grains, added fats, salt, and flavorings. None of these things is obesogenic on its own.
Inactivity comes third. People don't want to be active, and the modern environment is great at allowing people to live their lives with very little physical activity being needed.
Then you have things like genetics, sleep and circadian disruption, chronic stress, medications, socioeconomic factors, alcohol, toxicants, and the microbiome.
Key thing is figuring out what the biggest levers are for a particular person. But energy balance remains king, and encouraging personal agency over behavior is essential (e.g., no food will ever compel you to eat it).
