The introduction of glucagon-like peptide-1 (GLP-1) receptor agonists, reminiscent of 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 bettering 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 observe (they aren’t), or that possibly I don’t agree with utilizing prescription drugs over food plan for weight reduction. I wrote all about that right here.
I consider the brand new class of weight reduction drugs are unimaginable instruments that can assist to vary folks’s lives for the higher. However they aren’t all the puzzle; they’re solely only a piece, and there are some very actual limitations to their use.
Latest 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 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 pattern that could be attributed partially to GLP-1 drugs, 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 complex.
Limitations of GLP-1 Medicines in Addressing Inhabitants-Vast Epidemic
Price 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 usually cap spending or length for GLP-1 drugs. Whereas some folks qualify for GLP-1 meds by means of 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 the US than in Germany. Information 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, uncomfortable side effects, or gradual weight reduction.
In different phrases, so many individuals who would seemingly profit enormously from these drugs, simply can’t entry them in any respect, or for lengthy sufficient. Entry is decrease for folks 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 cheaper generic variations of semaglutide will seemingly be available on the market shortly after that. Will they be way more inexpensive? Solely time will inform.
Sustainability of Results: Whereas GLP-1 drugs are efficient for weight reduction, analysis means that these drugs 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 yr 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 shoppers who’re on GLP-1 agonist drugs, we focus not solely on meals, but additionally on relationship with meals and with way of life adjustments reminiscent of rising bodily exercise.
Limitations on Efficacy of GLP-1 Agonist Medicines: In response to 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 particular person, that might imply 80 kilos misplaced. That particular person 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 reminiscent of urge for food regulation and insulin sensitivity. These are clearly essential, however to actually impact change on weight problems charges, there must be a complete focus not solely on pharmacology, but additionally public well being interventions. A 2023 assessment in Nature Medication proposed that initiatives to deal with this concern which have 4 components: informing the general public about vitamin, enabling them to make health-promoting decisions, motivating them to make adjustments to their routines and habits, and influencing behaviour through social norms and different strategies.
The assessment steered rising lively transport, rising healthcare payor incentives, bettering entry to and affordability of wholesome meals, limiting availability and media advertising of high-calorie meals, bettering meals labeling, reformulating meals merchandise to be extra healthful, and rising entry to weight administration applications and bariatric surgical procedure.
Facet Results and Contraindications: Frequent uncomfortable side effects of GLP-1 drugs, reminiscent of nausea, vomiting, and gastrointestinal discomfort, can deter adherence. Moreover, these medicine are contraindicated for people with sure situations, reminiscent of 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 food plan do should 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 drugs:
Prioritize Protein and Fiber: GLP-1 drugs gradual gastric emptying, selling early satiety. Which means that most meals and snacks must be nutrient-dense to keep away from nutrient deficiencies and promote total well being. A food 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 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 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 food plan.
Hydration and Small, Frequent Meals: Folks on GLP-1 drugs usually expertise nausea, which will be mitigated by staying hydrated and consuming smaller, extra frequent meals. On nauseous days, incorporating meals which are mild on the abdomen, reminiscent of soups and smoothies, might help.
Conscious Consuming Practices: GLP-1 drugs scale back urge for food, creating a chance to observe aware consuming. Slowing down throughout meals, savoring meals, and listening to starvation cues might help reinforce wholesome consuming behaviors.
Rising Weight Loss Medicines
Along with current GLP-1 receptor agonists, a number of promising weight reduction drugs are beneath growth or awaiting approval:
- Orforglipron Eli Lilly is creating Orforglipron, an oral GLP-1 receptor agonist. This remedy may present another for sufferers preferring to not use injectables.
- CagriSema (Cagrilintide/Semaglutide Mixture) Novo Nordisk is advancing this mixture remedy, displaying 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 drugs supply important advantages for people battling weight problems, however they don’t seem to be 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.
