These “chemical shields” against the obesogenic environment not only facilitate satiety at lower caloric intake but also reduce the pervasive “food noise” described by many users, making it potentially easier to engage in other healthy lifestyle changes. These are important medicines coming at a time when obesogenic environments show little signs of being meaningfully reversed.&lt;/p&gt;&lt;p&gt;Importantly, the clinical effects of these weight loss therapies extend beyond weight reduction. Semaglutide has been shown to reduce cardiovascular events in people without diabetes, as demonstrated in the landmark SELECT trial [&lt;span&gt;1&lt;/span&gt;]. Tirzepatide, a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 receptor agonist (GLP-1RA), appears to offer even greater average weight loss and potentially additional metabolic benefits, though its cardiovascular impact remains to be confirmed.&lt;/p&gt;&lt;p&gt;The ongoing SURMOUNT-MMO trial described in this issue of &lt;i&gt;Obesity&lt;/i&gt; [&lt;span&gt;2&lt;/span&gt;] is designed to evaluate this question and much more. It is the pivotal placebo-controlled cardiovascular outcomes trial for tirzepatide in individuals without type 2 diabetes (T2D), following on from the soon to be reported SUPRASS CVOT (https://clinicaltrials.gov/study/NCT04255433) which tests the cardiovascular outcomes of tirzepatide versus an active comparator, dulaglutide, in people with T2D. SURMOUNT-MMO compares tirzepatide to placebo for a composite primary endpoint that includes a range of cardiovascular events, notably including heart failure—a cardiovascular condition more strongly associated with obesity than atherosclerotic outcomes.&lt;/p&gt;&lt;p&gt;Critically, however, in addition to the primary endpoint, SURMOUNT-MMO is also examining a series of important secondary outcomes [&lt;span&gt;2&lt;/span&gt;]. These include the incidence of T2D, changes in kidney function via estimated glomerular filtration rate, and physical functioning, each representing somewhat different pathways through which obesity causes harm: metabolic, hemodynamic, and mechanical. Other secondary and tertiary outcomes include heart failure hospitalization, obesity-related liver outcomes, cancers linked to obesity, and all-cause hospitalization [&lt;span&gt;2&lt;/span&gt;]. Consequently, this trial will offer an opportunity to assess both the broad direct and weight loss effects of tirzepatide in a controlled setting (Figure 1). Placebo-controlled randomized trials remain the gold standard for assessing both benefits and safety and are especially valuable for detecting outcomes that are relatively common. Even the best designed observational studies cannot provide this level of causal evidence.&lt;/p&gt;&lt;p&gt;Beyond clinical outcomes, health systems and policy makers are paying close attention to trials like SURMOUNT MMO due to economic implications.
