The introduction of glucagon-like peptide-1 (GLP-1) receptor agonists, comparable to semaglutide (Ozempic and Wegovy) is a breakthrough within the administration of weight problems. These medicines have confirmed to be very efficient in selling weight reduction and enhancing blood sugar ranges.
Whereas lots of people might imagine that I’ve one thing in opposition to GLP-1s – whether or not as a result of they’re ‘competitors’ for my apply (they aren’t), or that perhaps I don’t agree with utilizing prescription drugs over weight loss plan for weight reduction. I wrote all about that right here.
I consider the brand new class of weight reduction medicines are unimaginable instruments that can assist to alter individuals’s lives for the higher. However they aren’t the complete puzzle; they’re solely only a piece, and there are some very actual limitations to their use.
Current analysis suggests that weight problems charges within the US have dropped very barely – from 46% in 2022 to 45.6% in 2023. There was a 700% enhance in using GLP-1 agonist medicines between 2019 and 2023.
Though even a 0.04% change in weight problems charges could point out a basic downward development which may be attributed partially to GLP-1 medicines, there are good causes to consider that these medication is not going to drastically cut back the prevalence of weight problems…no less than, not now. However why?
The reply to this query is multifaceted and sophisticated.
Limitations of GLP-1 Medicines in Addressing Inhabitants-Broad Epidemic
Price and Accessibility: These medicines are tremendous costly – as in, over $15,000 a 12 months in some instances. This can be a big barrier for individuals who can’t afford to pay out of pocket, or who don’t have personal insurance coverage protection. Even for these with personal insurance coverage, firms typically cap spending or length for GLP-1 medicines. Whereas some individuals qualify for GLP-1 meds by way of Medicare or Medicaid, many don’t.
A current listening to of the US Senate Committee on Well being, Schooling, Labor, and Pensions revealed that Ozempic prices 15x extra in the USA than in Germany. Information on affected person discontinuation of GLP-1 receptor agonist medicines is inconclusive, however numbers vary from round 50% inside 3 months to 75% by the two 12 months mark. The explanations for going off the meds embrace value, negative effects, or sluggish weight reduction.
In different phrases, so many individuals who would possible profit tremendously from these medicines, simply can’t entry them in any respect, or for lengthy sufficient. Entry is decrease for individuals in sure racial and ethnic teams, that are additionally the teams which have the very best charges of weight problems (and the bottom entry to healthcare total).
The patents for a number of of those medicines are up in March, 2026, that means that inexpensive generic variations of semaglutide will possible be in the marketplace shortly after that. Will they be far more inexpensive? Solely time will inform.
Sustainability of Results: Whereas GLP-1 medicines are efficient for weight reduction, analysis means that these medicines are most likely a long-term dedication. For many individuals, their advantages are contingent on continued use. A research from the STEP 1 trial highlighted that two-thirds of the burden misplaced utilizing semaglutide was regained inside a 12 months after remedy discontinuation. Because the numbers point out, some weight regain is probably going, however that’s not essentially true for everybody.
After I work with shoppers who’re on GLP-1 agonist medicines, we focus not solely on meals, but in addition on relationship with meals and with life-style adjustments comparable to growing bodily exercise.
Limitations on Efficacy of GLP-1 Agonist Medicines: In line with Dr. Spencer Nadolsky, D.O. and Weight problems and Lipid Specialist, these meds do have their limits.
Proper now, the common is round 20% weight reduction with Tizepatide (Mounjaro). For a 400 pound individual, that may imply 80 kilos misplaced. That individual nonetheless has weight problems.
Along with this, Dr. Nadolsky bolstered the truth that not everybody responds to those medicines.
Root Causes of Weight problems: Weight problems is pushed by advanced components, together with socioeconomic disparities, meals system points, and sedentary existence. Conversely, GLP-1 medicines primarily goal processes comparable to urge for food regulation and insulin sensitivity. These are clearly necessary, however to actually impact change on weight problems charges, there needs to be a complete focus not solely on pharmacology, but in addition public well being interventions. A 2023 overview in Nature Drugs proposed that initiatives to handle this situation which have 4 components: informing the general public about vitamin, enabling them to make health-promoting selections, motivating them to make adjustments to their routines and habits, and influencing behaviour through social norms and different strategies.
The overview recommended growing lively transport, growing healthcare payor incentives, enhancing entry to and affordability of wholesome meals, limiting availability and media advertising of high-calorie meals, enhancing meals labeling, reformulating meals merchandise to be extra healthful, and growing entry to weight administration packages and bariatric surgical procedure.
Aspect Results and Contraindications: Frequent negative effects of GLP-1 medicines, comparable to nausea, vomiting, and gastrointestinal discomfort, can deter adherence. Moreover, these medication are contraindicated for people with sure circumstances, comparable to kidney illness, sure cancers, and a historical past of pancreatitis.
The Position of Dietary Interventions
GLP-1 medicines are efficient for most individuals, however adjustments in weight loss plan do have to be a part of their use. Dietary methods can improve the efficacy of remedy whereas supporting long-term well being.
Listed below are some ideas for consuming whereas on a GLP-1 medicines:
Prioritize Protein and Fiber: GLP-1 medicines sluggish gastric emptying, selling early satiety. Which means that most meals and snacks needs to be nutrient-dense to keep away from nutrient deficiencies and promote total well being. A weight loss plan wealthy in lean proteins (e.g., meat and fish, tofu, eggs, Greek yogurt and ricotta, beans and lentils) helps to keep up muscle mass. Getting ~25+ grams of fiber per day from greens, entire grains, and fruits, helps maintain fullness and helps blood sugar management. Don’t sleep on beans or soy meals as a approach to get high-quality protein and fibre in a single place!
Reduce Extremely-Processed Meals: Processed meals excessive in refined carbohydrates, added sugars, and unhealthy fat can counteract the advantages of GLP-1 medicines. I like to recommend specializing in entire, minimally processed meals to enhance total metabolic well being. That additionally means minimizing alcohol and different lower-quality meals to assist maximize vitamins in your weight loss plan.
Hydration and Small, Frequent Meals: Individuals on GLP-1 medicines typically expertise nausea, which may be mitigated by staying hydrated and consuming smaller, extra frequent meals. On nauseous days, incorporating meals which might be mild on the abdomen, comparable to soups and smoothies, will help.
Aware Consuming Practices: GLP-1 medicines cut back urge for food, creating a chance to apply aware consuming. Slowing down throughout meals, savoring meals, and listening to starvation cues will help reinforce wholesome consuming behaviors.
Rising Weight Loss Medicines
Along with present GLP-1 receptor agonists, a number of promising weight reduction medicines are beneath growth or awaiting approval:
- Orforglipron Eli Lilly is growing Orforglipron, an oral GLP-1 receptor agonist. This medicine might present an alternate for sufferers preferring to not use injectables.
- CagriSema (Cagrilintide/Semaglutide Mixture) Novo Nordisk is advancing this mixture remedy, exhibiting important weight reduction results in early trials.
- Retatrutide Retatrutide is a triple-hormone receptor agonist, with early research reporting substantial weight discount.
- VK2735 Viking Therapeutics is exploring VK2735, an oral remedy with promising preliminary outcomes.
Conclusion
GLP-1 medicines provide important advantages for people fighting weight problems, however they don’t seem to be a panacea for the broader epidemics. Addressing these advanced, multifactorial challenges requires a complete method that mixes medical innovation with sturdy public well being efforts. By integrating dietary methods, selling equitable entry to care, and tackling systemic points, we are able to make significant progress towards reversing the developments in weight problems.
