The introduction of glucagon-like peptide-1 (GLP-1) receptor agonists, akin 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 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 follow (they aren’t), or that possibly I don’t agree with utilizing prescription drugs over weight loss plan for weight reduction. I wrote all about that right here.
I imagine the brand new class of weight reduction drugs are unimaginable instruments that may 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 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 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 basic downward pattern which may be attributed partially to GLP-1 drugs, there are good causes to imagine that these medicine won’t drastically cut back the prevalence of weight problems…at the least, not now. However why?
The reply to this query is multifaceted and sophisticated.
Limitations of GLP-1 Drugs in Addressing Inhabitants-Vast Epidemic
Price and Accessibility: These drugs are tremendous costly – as in, over $15,000 a yr 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, corporations usually 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 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 embody price, unintended effects, or sluggish weight reduction.
In different phrases, so many individuals who would probably profit enormously 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 very best charges of weight problems (and the bottom entry to healthcare general).
The patents for a number of of those drugs are up in March, 2026, which means that cheaper generic variations of semaglutide will probably be available on the market shortly after that. Will they be far 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 research from the STEP 1 trial highlighted that two-thirds of the burden 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 in addition on relationship with meals and with life-style adjustments akin to rising bodily exercise.
Limitations on Efficacy of GLP-1 Agonist Drugs: 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 complicated elements, together with socioeconomic disparities, meals system points, and sedentary life. Conversely, GLP-1 drugs primarily goal processes akin to urge for food regulation and insulin sensitivity. These are clearly vital, 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 overview in Nature Drugs proposed that initiatives to deal with this concern 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 by way of social norms and different strategies.
The overview urged rising energetic transport, rising healthcare payor incentives, bettering entry to and affordability of wholesome meals, limiting availability and media advertising and marketing 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: Widespread unintended effects of GLP-1 drugs, akin to nausea, vomiting, and gastrointestinal discomfort, can deter adherence. Moreover, these medicine are contraindicated for people with sure situations, akin 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 weight loss 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 suggestions for consuming whereas on a GLP-1 drugs:
Prioritize Protein and Fiber: GLP-1 drugs sluggish gastric emptying, selling early satiety. Because of this most meals and snacks needs to be nutrient-dense to keep away from nutrient deficiencies and promote general 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 drugs. I like to recommend specializing in entire, 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 loss plan.
Hydration and Small, Frequent Meals: Individuals on GLP-1 drugs usually expertise nausea, which could be mitigated by staying hydrated and consuming smaller, extra frequent meals. On nauseous days, incorporating meals which are light on the abdomen, akin to soups and smoothies, might help.
Conscious Consuming Practices: GLP-1 drugs cut back urge for food, creating a chance to follow aware consuming. Slowing down throughout meals, savoring meals, and listening to starvation cues might help reinforce wholesome consuming behaviors.
Rising Weight Loss Drugs
Along with present GLP-1 receptor agonists, a number of promising weight reduction drugs are below growth or awaiting approval:
- Orforglipron Eli Lilly is creating Orforglipron, an oral GLP-1 receptor agonist. This medicine may present an alternate for sufferers preferring to not use injectables.
- CagriSema (Cagrilintide/Semaglutide Mixture) Novo Nordisk is advancing this mix 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 drugs supply important advantages for people scuffling with weight problems, however they don’t seem to be a panacea for the broader epidemics. Addressing these complicated, multifactorial challenges requires a complete strategy 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 traits in weight problems.
