The introduction of glucagon-like peptide-1 (GLP-1) receptor agonistscomparable 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 towards 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 prescribed drugs over weight-reduction plan for weight reduction. I wrote all about that right here.
I consider the brand new class of weight reduction medicines are unbelievable instruments that can assist to vary folks’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% improve in using GLP-1 agonist medicines between 2019 and 2023.
Though even a 0.04% change in weight problems charges could point out a normal downward development that could be attributed partially to GLP-1 medicines, there are good causes to consider that these medicine is not going to drastically scale back the prevalence of weight problems…a minimum of, not now. However why?
The reply to this query is multifaceted and sophisticated.
Limitations of GLP-1 Medicines in Addressing Inhabitants-Huge Epidemic
Value and Accessibility: These medicines are tremendous costly – as in, over $15,000 a 12 months in some instances. It is a big barrier for individuals who can’t afford to pay out of pocket, or who don’t have non-public insurance coverage protection. Even for these with non-public insurance coverage, firms typically cap spending or period for GLP-1 medicines. Whereas some folks qualify for GLP-1 meds by Medicare or Medicaid, many don’t.
A latest listening to of the US Senate Committee on Well being, Schooling, Labor, and Pensions revealed that Ozempic prices 15x extra in america 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 embody value, negative effects, or gradual weight reduction.
In different phrases, so many individuals who would probably profit drastically from these medicines, simply can’t entry them in any respect, or for lengthy sufficient. Entry is decrease for folks in sure racial and ethnic teamsthat are additionally the teams which have the very best charges of weight problems (and the bottom entry to healthcare general).
The patents for a number of of those medicines are up in March, 2026, which means that inexpensive generic variations of semaglutide will probably 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 examine from the STEP 1 trial highlighted that two-thirds of the load 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.
Once I work with purchasers who’re on GLP-1 agonist medicines, we focus not solely on meals, but in addition on relationship with meals and with way of life adjustments comparable to growing bodily exercise.
Limitations on Efficacy of GLP-1 Agonist Medicines: Based on Dr. Spencer NadolskyD.O. and Weight problems and Lipid Specialist, these meds do have their limits.
Proper now, the typical is round 20% weight reduction with Tizepatide (Mounjaro). For a 400 pound particular person, that will imply 80 kilos misplaced. That particular person 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 elementstogether with socioeconomic disparities, meals system points, and sedentary life. Conversely, GLP-1 medicines primarily goal processes comparable to urge for food regulation and insulin sensitivity. These are clearly essential, 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 deal with this subject which have 4 elements: informing the general public about diet, 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 advised growing energetic transport, growing healthcare payor incentives, enhancing entry to and affordability of wholesome meals, limiting availability and media advertising and marketing of high-calorie meals, enhancing meals labeling, reformulating meals merchandise to be extra healthful, and growing entry to weight administration applications and bariatric surgical procedure.
Aspect Results and Contraindications: Widespread negative effects of GLP-1 medicinescomparable to nausea, vomiting, and gastrointestinal discomfort, can deter adherence. Moreover, these medicine are contraindicated for people with sure situations, comparable to kidney illness, sure cancers, and a historical past of pancreatitis.
The Function of Dietary Interventions
GLP-1 medicines are efficient for most individuals, however adjustments in weight-reduction plan do must 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 gradual 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 general well being. A weight-reduction plan wealthy in lean proteins (e.g., meat and fish, tofu, eggs, Greek yogurt and ricotta, beans and lentils) helps to take care of muscle mass. Getting ~25+ grams of fiber per day from greens, complete grains, and fruits, helps maintain fullness and helps blood sugar management. Don’t sleep on beans or soy meals as a solution to get high-quality protein and fibre in a single place!
Decrease 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 complete, minimally processed meals to enhance general metabolic well being. That additionally means minimizing alcohol and different lower-quality meals to assist maximize vitamins in your weight-reduction plan.
Hydration and Small, Frequent Meals: Folks 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 are light on the abdomen, comparable to soups and smoothies, will help.
Aware Consuming Practices: GLP-1 medicines scale back urge for food, creating a possibility to apply conscious 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 below growth or awaiting approval:
- Orforglipron Eli Lilly is growing Orforglipron, an oral GLP-1 receptor agonist. This remedy may present an alternate for sufferers preferring to not use injectables.
- CagriSema (Cagrilintide/Semaglutide Mixture) Novo Nordisk is advancing this mixture remedy, displaying vital weight reduction results in early trials.
- Retras 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 supply vital advantages for people scuffling with 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 strong 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 traits in weight problems.
