The difference between HOTs and previous weight loss drugs and supplements is profound. Despite decades of development and hundreds of millions of prescriptions nothing in the weight loss space has ever triggered anything approaching the disruption we are seeing now.
Previous weight loss drugs worked primarily by suppressing appetite through stimulating the central nervous system (phentermine), blocking fat absorption in the gut (orlistat), or modulating mood and reward circuits (bupropion-naltrexone). These mechanisms produced modest results, with phentermine-topiramate achieving roughly 8% average body weight loss; orlistat, about 3%; bupropion-naltrexone, roughly 3%. These were marginal improvements with significant side effects including elevated heart rate, insomnia, anxiety, oily stools, fecal urgency and dependency risks. This is not including the long list of failed weight loss pharmaceuticals that caused serious illness, injury or death before being pulled from the shelves.
GLP-1 drugs achieve 15–22% average body weight loss with Retatrutide, still in trials, showing up to 28%. Far from an incremental improvement over prior drugs, it is a major leap into a different category of effectiveness, comparable to (and soon exceeding) bariatric surgery.
Previous weight loss drugs were blunt instruments that pushed on one lever (suppress appetite, block fat absorption, stimulate metabolism) and left the underlying biology unchanged. GLP-1s work by mimicking hormones that the body naturally produces, activating receptors throughout the brain, gut, pancreas, and cardiovascular system. They reduce food noise rather than simply making food less palatable or digestion less efficient. Users consistently describe this not as feeling sick or suppressed, but as simply not being hungry in the way they used to be. The term that has organically emerged is "liquid willpower."
Supplements occupy a different but equally important contrast. The weight loss supplement industry, which includes products like green tea extract, garcinia cambogia, raspberry ketones, conjugated linoleic acid, and hundreds of others. These are characterized by weak effect sizes (typically 1–2 kg over several months in the best-designed trials), high placebo response rates, inconsistent quality control, and a regulatory environment that permits marketing far in advance of scientific evidence. These are not even close to the same category of intervention as GLP-1 drugs.
Finally, and crucially, previous weight loss drugs produced weight loss only. GLP-1s produce weight loss plus cardiovascular improvement, addiction reduction, sleep apnea resolution, joint health benefits, and more. They are not just more effective weight loss drugs, they are a categorically different kind of medicine - Health Optimizer Therapies.
We are entering a new era of healthcare based on a categorically different kind of medicine whose purpose is not just to save us from illness, but to help us be the best version of ourselves.
The next generation of HOTs will trigger a multi-trillion-dollar global disruption, affecting dozens of industries across multiple sectors, driving a radical global improvement in health and wellness encompassing at least 1 billion people worldwide before 2040.
Optimizing well with advanced HOTs will soon become as important as eating well with nutritious foods. Nations, industries, and individuals that recognize this early and act decisively will be best positioned to capture the extraordinary benefits of this transformation.
