The introduction of glucagon-like peptide-1 (GLP-1) receptor agonists, corresponding to semaglutide (Ozempic and Wegovy) is a breakthrough within the administration of weight problems. These drugs 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 observe (they aren’t), or that perhaps I don’t agree with utilizing prescription drugs over eating regimen for weight reduction. I wrote all about that right here.
I imagine the brand new class of weight reduction drugs are unimaginable instruments that can assist to vary individuals’s lives for the higher. However they aren’t your complete puzzle; they’re solely only a piece, and there are some very actual limitations to their use.
Current analysis means 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 the usage of GLP-1 agonist drugs between 2019 and 2023.
Though even a 0.04% change in weight problems charges could point out a normal downward development which may be attributed partially to GLP-1 drugs, there are good causes to imagine that these medicine is not going to drastically cut back the prevalence of weight problems…at the least, not now. However why?
The reply to this query is multifaceted and complex.
Limitations of GLP-1 Medicines in Addressing Inhabitants-Huge Epidemic
Value and Accessibility: These drugs are tremendous costly – as in, over $15,000 a yr in some circumstances. 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, corporations typically cap spending or period for GLP-1 drugs. 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 america than in Germany. Knowledge on affected person discontinuation of GLP-1 receptor agonist drugs is inconclusive, however numbers vary from round 50% inside 3 months to 75% by the two yr mark. The explanations for going off the meds embrace price, unintended effects, or sluggish weight reduction.
In different phrases, so many individuals who would doubtless profit vastly from these drugs, 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 best charges of weight problems (and the bottom entry to healthcare total).
The patents for a number of of those drugs are up in March, 2026, which means that inexpensive generic variations of semaglutide will doubtless be available on the market shortly after that. Will they be rather more reasonably priced? Solely time will inform.
Sustainability of Results: Whereas GLP-1 drugs are efficient for weight reduction, analysis means that these drugs are in all probability 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 yr after therapy 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 drugs, we focus not solely on meals, but in addition on relationship with meals and with life-style adjustments corresponding to growing bodily exercise.
Limitations on Efficacy of GLP-1 Agonist Medicines: Based on 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 might imply 80 kilos misplaced. That individual nonetheless has weight problems.
Along with this, Dr. Nadolsky strengthened the truth that not everybody responds to those drugs.
Root Causes of Weight problems: Weight problems is pushed by advanced elements, together with socioeconomic disparities, meals system points, and sedentary life. Conversely, GLP-1 drugs primarily goal processes corresponding to urge for food regulation and insulin sensitivity. These are clearly essential, however to essentially 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 evaluation in Nature Drugs proposed that initiatives to deal with this problem which have 4 components: 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 by way of social norms and different strategies.
The evaluation 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: Widespread unintended effects of GLP-1 drugs, corresponding to nausea, vomiting, and gastrointestinal discomfort, can deter adherence. Moreover, these medicine are contraindicated for people with sure circumstances, corresponding to kidney illness, sure cancers, and a historical past of pancreatitis.
The Position of Dietary Interventions
GLP-1 drugs are efficient for most individuals, however adjustments in eating regimen do must be a part of their use. Dietary methods can improve the efficacy of therapy whereas supporting long-term well being.
Listed here are some suggestions for consuming whereas on a GLP-1 drugs:
Prioritize Protein and Fiber: GLP-1 drugs sluggish gastric emptying, selling early satiety. Which means most meals and snacks needs to be nutrient-dense to keep away from nutrient deficiencies and promote total well being. A eating regimen 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 option 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 drugs. I like to recommend specializing in complete, 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 eating regimen.
Hydration and Small, Frequent Meals: Folks on GLP-1 drugs 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, corresponding to soups and smoothies, may also help.
Conscious Consuming Practices: GLP-1 drugs cut back urge for food, creating a possibility to observe conscious consuming. Slowing down throughout meals, savoring meals, and listening to starvation cues may also help reinforce wholesome consuming behaviors.
Rising Weight Loss Medicines
Along with present GLP-1 receptor agonists, a number of promising weight reduction drugs are below improvement or awaiting approval:
- Orforglipron Eli Lilly is growing Orforglipron, an oral GLP-1 receptor agonist. This remedy might present another 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.
- 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 drugs provide important advantages for people fighting weight problems, however they aren’t a panacea for the broader epidemics. Addressing these advanced, multifactorial challenges requires a complete strategy that mixes medical innovation with strong public well being efforts. By integrating dietary methods, selling equitable entry to care, and tackling systemic points, we will make significant progress towards reversing the tendencies in weight problems.
