But treating obesity is not just about weight management. This article explores another dimension of treatment: what can happen on a psychological level when the body and relationship to food change rapidly.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With GLP-1 agonists and the new molecules that are gradually being introduced, it is now possible to achieve weight loss levels that would have been difficult to imagine with the medical treatments we had just a few years ago.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is a major therapeutic advance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But when a treatment acts quickly on hunger, satiety, food cravings, and sometimes even on interest in food, a question deserves to be asked:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What happens when chemistry changes faster than the person has time to adapt?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the CoAttitude Clinic, in obesity medicine, I call this possible experience the Chemical Void.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is not a recognized medical diagnosis. It is a clinical concept that allows for putting words to an experience that some patients may encounter when something that previously occupied an important place in their equilibrium quickly disappears.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>When the \u00abfood noise\u00bb dies down<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Patients sometimes describe it in spectacular terms:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00ab I don\u2019t think about it anymore. Before, I thought about what I was going to eat all day long. Now, nothing. \u00bb<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Scientific literature is increasingly interested in food noise, which consists of repetitive, sometimes intrusive thoughts about food.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">GLP-1-type treatments can reduce hunger, food cravings, and the attraction to certain foods. For many people, this reduction represents a real liberation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, there is room for something else.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But this new psychological availability sometimes raises an unexpected question:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>of space for what?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because eating didn\u2019t always have the sole function of satisfying hunger.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Food could comfort, calm, celebrate, occupy, reward, anesthetize an emotion, fill a lonely evening, or simply provide several small moments of pleasure in a difficult day.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the medication greatly diminishes this interest, the person may discover a space they had never really had to inhabit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is a first dimension of the Chemical Void:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The treatment can withdraw a response before the person has built up what might take its place.<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>When pleasure changes too<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This observation is all the more interesting because the action of GLP-1 does not only concern hunger and satiety.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The brain circuits involved in motivation and reward are also affected.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A systematic review published in 2024 in <em><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/38945189\/\" type=\"link\" id=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/38945189\/\">Physiology &amp; Behavior<\/a><\/em> The authors analyzed human studies involving GLP-1 agonists and reward-related behaviors. In particular, they report a decrease in energy intake and changes in brain activation in response to food and rewards. They also highlight possible interactions with the dopaminergic mechanisms involved in motivation and reward.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most of the time, reducing this power of the food reward is precisely what we are looking for.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But there are two things to be distinguished:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No longer being a prisoner of a desire is not the same as no longer having a desire for anything.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In some patients, it is therefore necessary to be able to listen to the onset of a more general decrease in drive: less interest in food, certainly, but perhaps also less enthusiasm, less desire, less pleasure, or that strange feeling of \u00absomething having gone out.\u00bb.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Research today does not allow the existence of a specific syndrome caused by these drugs to be confirmed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, it gives us an additional reason to ask the question.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>And what if those extra pounds had also served some purpose?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is another dimension of the Chemical Void, much more intimate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We often talk about weight as a problem that the patient should get rid of.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But the story of some patients tells of something more complex.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I have had the opportunity to accompany a person who deeply wanted to lose weight and who had succeeded in doing so several times.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yet each weight loss gradually awakened an extremely painful sensation: the feeling of being exposed to others.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This feeling had its roots very deep in his history, going back to a childhood marked by abandonment and poverty.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">His desire to lose weight was completely genuine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But another part of her had learned, long ago, that this bodily envelope could also protect.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the envelope disappeared, the vulnerability reappeared.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And until this dimension was accompanied, the weight gain episodes kept happening.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another person once told me a very different phrase:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00abI am finally ready to no longer hide behind my body. I can also feel strong in a body that is not as large.\u00bb<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Everything was there.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Weight was no longer necessary to fulfill the same function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This person wasn't just giving up kilos; she had started to build another way of feeling safe.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This obviously does not mean that obesity systematically hides a trauma or that weight always has a psychological function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But this means that when such a function exists, quickly modifying the body without recognizing it can leave the person without the protection they used to have for a very long time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Ghost Corps and the Chemical Void: two different shifts<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It is here that it is important to distinguish two phenomena that I encounter in my practice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The Ghost Body appears when the brain continues to inhabit a body that no longer exists.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The Chemical Void appears when the treatment eliminates a function before the person has built what will take its place.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the first case, the internal image of the body is out of sync with the real body.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the second, the emotional and hedonistic adaptation may lag behind the biological transformation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And the two can obviously coexist. The body changes. Hunger changes. Desires change. The relationship to pleasure can change. The way others look at us can change.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, identity, emotions, protective mechanisms, and sources of comfort do not necessarily transform at the same rate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Before embarking on a weight loss program, ask if the weight is holding on to something beyond itself.&nbsp;<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">That is why the arrival of extremely effective medicines imposes, in my opinion, not less support but more.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Access to these medicines is essential, and so are information and support for patients.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Prescribing an obesity treatment should therefore not only consist of asking the question:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00ab How many kilos can this person lose? \u00bb<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is often also necessary to ask:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00abWhat might change in life when these kilos, this hunger and this relationship with food are no longer there in the same way?\u00bb<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The 10 questions of the Chemical Void<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Before the treatment, and then during weight loss, here are ten questions we can explore:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Is food today one of your main sources of pleasure?<\/li>\n\n\n\n<li>Do you sometimes eat to calm yourself down, to comfort yourself, to reward yourself, or to fill a void?<\/li>\n\n\n\n<li>What do you do when you are sad, anxious, lonely, frustrated or exhausted without using food?<\/li>\n\n\n\n<li>If your thoughts about food decreased enormously tomorrow, what would take that place?<\/li>\n\n\n\n<li>Have you ever felt a sense of vulnerability, exposure, or \u00abunmasking\u00bb during a previous weight loss?<\/li>\n\n\n\n<li>Has your body or your weight ever given you, consciously or not, the impression of protecting you from the gaze, desire, closeness, or judgment of others?<\/li>\n\n\n\n<li>Can you imagine being safe and feeling strong in a smaller body?<\/li>\n\n\n\n<li>Is your current identity strongly linked to your weight or your body appearance?<\/li>\n\n\n\n<li>Apart from food, what are your main sources of pleasure, comfort, connection and inspiration today?<\/li>\n\n\n\n<li>If your body changed much faster than expected, what support would you need to recognize yourself and continue to feel like yourself?<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">There is no wrong answer to this questionnaire. There are no good or bad answers. Everyone has their own.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A difficult answer is not a contraindication to losing weight. It is an indication of what will need to be accompanied.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Five antidotes to Chemical Voids<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">I propose this prevention through five axes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>1 Building a map of pleasures<\/strong><\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>2 Give another response to the emotions<\/strong><\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>3 Identifying the protective function of the body<\/strong><\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>4 Gradually adapting to the new body<\/strong><\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>5 Monitoring and nurturing the vital momentum<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These five dimensions can be worked on before and during weight loss so that the physical transformation can gradually be accompanied by an emotional, hedonistic, and identity-based transformation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Losing weight without losing oneself<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Modern obesity medications offer us an extraordinary opportunity: to reduce some of the biological pressure that drives some people to overeat and makes weight loss so difficult to maintain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They sometimes make it possible to silence, almost suddenly, a noise that sometimes takes up an immense space.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yet they cannot decide on our behalf what we will do with silence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That may be where another part of the treatment begins.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the noise of food subsides, when the body transforms, when the old shell becomes less necessary, one sometimes has to help the person build new sources of pleasure, security, identity, and momentum.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because treating obesity should not only be about losing weight.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The treatment should allow the person to lose weight and find their own way in life.<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Modern treatments for obesity can quickly transform hunger, food pleasure, and the body.
