The introduction of glucagon-like peptide-1 (GLP-1) receptor agonists, equivalent 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.
While lots of people might imagine that I’ve one thing towards GLP-1s – whether or not as a result of they’re ‘competition’ 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 consider the brand new class of weight reduction drugs are unbelievable instruments that may assist to alter individuals’s lives for the higher. But they aren’t your entire puzzle; they’re solely only a piece, and there are some very actual limitations to their use.
Recent analysis suggests that weight problems charges within the US have dropped very barely – from 46% in 2022 to 45.6% in 2023. There has been a 700% enhance in the usage of GLP-1 agonist drugs between 2019 and 2023.
Although even a 0.04% change in weight problems charges might point out a common downward pattern which may be attributed partially to GLP-1 drugs, 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. But why?
The reply to this query is multifaceted and complex.
Limitations of GLP-1 Medications in Addressing Population-Wide Epidemic
Cost and Accessibility: These drugs are tremendous costly – as in, over $15,000 a yr in some circumstances. This is 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. While 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 Health, Education, Labor, and Pensions revealed that Ozempic prices 15x extra within the United States than in Germany. Data 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 causes for going off the meds embrace value, uncomfortable side effects, or gradual weight reduction.
In different phrases, so many individuals who would doubtless profit significantly from these drugs, simply can’t entry them in any respect, or for lengthy sufficient. Access 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 drugs are up in March, 2026, that means that cheaper generic variations of semaglutide will doubtless be in the marketplace shortly after that. Will they be rather more inexpensive? Only time will inform.
Sustainability of Effects: While 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. As the numbers point out, some weight regain is probably going, however that’s not essentially true for everybody.
When I work with purchasers who’re on GLP-1 agonist drugs, we focus not solely on meals, but additionally on relationship with meals and with life-style adjustments equivalent to rising bodily exercise.
Limitations on Efficacy of GLP-1 Agonist Medications: According to Dr. Spencer Nadolsky, D.O. and Obesity and Lipid Specialist, these meds do have their limits.
Right 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.
In addition to this, Dr. Nadolsky bolstered the truth that not everybody responds to those drugs.
Root Causes of Obesity: Obesity is pushed by advanced components, together with socioeconomic disparities, meals system points, and sedentary existence. Conversely, GLP-1 drugs primarily goal processes equivalent to urge for food regulation and insulin sensitivity. These are clearly essential, however to essentially impact change on weight problems charges, there must be a complete focus not solely on pharmacology, but additionally public well being interventions. A 2023 evaluate in Nature Medicine proposed that initiatives to deal with this concern 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 through social norms and different strategies.
The evaluate urged rising energetic transport, rising 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 rising entry to weight administration packages and bariatric surgical procedure.
Side Effects and Contraindications: Common uncomfortable side effects of GLP-1 drugs, equivalent to nausea, vomiting, and gastrointestinal discomfort, can deter adherence. Additionally, these medication are contraindicated for people with sure circumstances, equivalent to kidney illness, sure cancers, and a historical past of pancreatitis.
The Role of Dietary Interventions
GLP-1 drugs are efficient for most individuals, however adjustments in weight loss plan do should be a part of their use. Dietary methods can improve the efficacy of remedy whereas supporting long-term well being.
Here are some suggestions for consuming whereas on a GLP-1 drugs:
Prioritize Protein and Fiber: GLP-1 drugs gradual gastric emptying, selling early satiety. This implies that most meals and snacks must 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!
Minimize Ultra-Processed Foods: 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 weight loss plan.
Hydration and Small, Frequent Meals: People on GLP-1 drugs usually expertise nausea, which might be mitigated by staying hydrated and consuming smaller, extra frequent meals. On nauseous days, incorporating meals which can be mild on the abdomen, equivalent to soups and smoothies, may help.
Mindful Eating Practices: GLP-1 drugs cut back urge for food, creating a chance to follow conscious consuming. Slowing down throughout meals, savoring meals, and listening to starvation cues may help reinforce wholesome consuming behaviors.
Emerging Weight Loss Medications
In addition to current GLP-1 receptor agonists, a number of promising weight reduction drugs are beneath improvement or awaiting approval:
- Orforglipron Eli Lilly is growing Orforglipron, an oral GLP-1 receptor agonist. This remedy may present another for sufferers preferring to not use injectables.
- CagriSema (Cagrilintide/Semaglutide Combination) Novo Nordisk is advancing this mix 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 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 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.
