As a result, the nutritional gaps already present in a calorie-restricted diet seem to be amplified.\u201d<\/p>\n<p>Researchers analyzed data from 332 adults with a BMI of 27 kg\/m<sup>2<\/sup> or higher who used the Robin Health app. Participants self-reported GLP-1 use. Macronutrient composition was determined using a photo recognition food logging system within the app. <\/p>\n<p>Of the study group, 116 reported using a GLP-1 (mean age, 52.5 years; 72.4% women; mean baseline BMI, 31.3 kg\/m<sup>2<\/sup>) and 216 did not use a GLP-1 (mean age, 50 years; 63% women; mean baseline BMI, 30.6 kg\/m<sup>2<\/sup>). <\/p>\n<p>Adults who used a GLP-1 had lower daily energy (1,102 kcal vs. 1,281 kcal; <i>P<\/i> = .001), protein (53.8 g vs. 62 g; <i>P<\/i> = .004), carbohydrate (128 g vs. 143 g; <i>P<\/i> &lt; .001) and fat intake (39.7 g vs. 45.7 g;<i> P<\/i> &lt; .001) than nonusers. The proportion of one\u2019s diet that consisted of protein (19.9% vs. 18.9%), carbohydrates (46.7% vs. 46.2%) and fat (32.7% vs. 33.5%) was similar between GLP-1 users and nonusers, respectively.<\/p>\n<p>\u201cThis suggests that GLP-1 receptor agonists appear to induce a proportional appetite suppression rather than selective changes in dietary preference, which has important implications for how we counsel patients,\u201d Vinelli said.<\/p>\n<p>Of those who used a GLP-1, 87.9% did not meet protein intake recommendations from the Italian Society of Human Nutrition. <\/p>\n<p>Adults using a GLP-1 were more likely to skip breakfast (31.3% of days vs. 16.1%; <i>P <\/i>&lt; .001), lunch (30.5% of days vs. 18.2%; <i>P <\/i>&lt; .001) and dinner (40.4% of days vs. 29.6%; <i>P <\/i>&lt; .001) than those not using a GLP-1. <\/p>\n<p>Among adults with at least two weight entries, the GLP-1 group lost more weight (mean change, \u20132.5 percentage points vs. \u20130.2 percentage points; <i>P<\/i> &lt; .001) and had a higher proportion of participants lose at least 5% of their body weight (22.5% vs. 3.1%; <i>P<\/i> &lt; .001) than nonusers.<\/p>\n<p>Vinelli said the findings emphasize how important it is for people with obesity to regularly consult with a nutritionist or dietitian when using a GLP-1.<\/p>\n<p>\u201cSpecifically, our data highlight practical priorities: actively monitoring protein intake, as most patients appear unable to meet even minimum recommended levels through habitual eating alone, but also all nutrients intake; and addressing meal skipping, particularly dinner, which reduces opportunities for adequate protein distribution,\u201d Vinelli said. \u201cIn this context, digital applications like Robin emerge as valuable tools to monitor and analyze patients\u2019 dietary habits, assess adherence to nutritional recommendations and support more effective and personalized dietary management.\u201d<\/p>\n<p>Vinelli said the researchers plan to conduct another study to analyze micronutrient composition, and that more research is needed to confirm the findings in larger study cohorts and to assess macronutrient intake during dose titration of the drugs.<\/p>\n<h2>For more information:<\/h2>\n<p>      <b>Valentina Vinelli<\/b><b>, <\/b><b>PhD<\/b><b>,<\/b> can be reached at valentina@robin.health.<\/p>\n<div class=\"article__content--footer\">\n<div class=\"publisher-logo\">\n    <span>Published by:<\/span><br \/>\n    <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.healio.com\/~\/media\/h5\/feature\/news\/publogos\/et.svg?la=en&amp;h=23&amp;w=148&amp;hash=7DBE65E47ABE522DBAC4A3C80BB97B4E\" class=\"logo-img\" height=\"23\" alt=\"endocrine today logo\" width=\"148\"\/>\n  <\/div>\n<div class=\"sources-references-disclosures\">\n<h3>Sources\/Disclosures<\/h3>\n<h2> Source: <\/h2>\n<p class=\"citation\">Vinelli V, et al.
