Patients are spending significant money on protocols that have no meaningful clinical backing.

From a focus on diet pills and fasting to intuitive eating and Paleo plates, there’s never a shortage of nutrition trends, often mirroring complex and sometimes problematic sociocultural contexts. ^[]^[]

Some trends stick, some fade into infamy, and others get a marketing makeover only to reappear under a new name (think Atkins–>keto).

From GLP-1 receptor agonists to continuous glucose monitors, nutrition advice is becoming more personalized, more data-driven, and increasingly tied to metabolic health. At the same time, patients are encountering a fast-growing market of supplements, DTC platforms, and “optimization” protocols that can outpace the evidence.

When it comes to nutrition trends, the challenge for physicians is separating useful shifts from wellness noise. Here’s what experts say is worth watching, and what deserves a more cautious conversation with patients.

GLP-1s are changing the way we think about food

Kristen Kuminski, RD, CDN, a registered dietitian nutritionist specializing in metabolic health, weight management, and nutrition support for individuals using GLP-1s, says weight loss drugs are reshaping nutrition recommendations in ways that may, in turn, render the medication trend unnecessary.

“As more people use these drugs, protein optimization and muscle preservation are becoming mainstream clinical conversations rather than niche fitness topics,” she says. “That shift is legitimate and worth reinforcing with patients.”

Food as medicine is a big deal

Kuminski adds that 2027 may see more food-as-medicine specificity.

“Not just ‘eat more plants,’ but targeted dietary interventions for insulin resistance, microbiome support, and metabolic flexibility,” she says. “The interest in continuous glucose monitoring outside of diabetes management is growing, and it’s changing how patients understand their own responses to food in real time.”

The supplement industry is (still) booming

The global food supplement market is booming, having increased from $238.5 billion in 2025 to an estimated $266.4 billion in 2026. ^[] But not every supplement is worth its weight.

For example, research shows that brain-boosting supplements may not deliver on what they promise, and daily supplements likely don’t magically protect against cancer or other conditions. ^[]^[]

“The risks to flag in the clinic are the supplement stacks being marketed around longevity and optimization, many of which are well ahead of any evidence,” Kuminski says. “Patients are spending significant money on protocols that have no meaningful clinical backing.” Instead, she says, clinicians should encourage patients to focus on real lifestyle shifts. “The interventions that actually move the needle on long-term health outcomes remain consistent: adequate protein, resistance training, sleep, stress management, and a minimally processed diet.”

Protein and fiber-maxing are popular, but lack nuance

Michael Dosik, MD, an internist at the Medical Offices of Manhattan, says the “maxxing” trends are here to stay. While they may be rooted in evidence and benefits, they can also be taken too far.

“Some major nutrition trends for 2026 include diets focused on high protein and high fiber,” he says. “Generally, these trends have been helpful because they help people stay full longer and promote gut health. However, these diets can become harmful if taken to the extreme, since good nutrition still requires balance.”

Full-fat dairy is making a comeback

Once demonized, full-fat dairy may be back, says Adiana Castro, MS, RDN, CLT, CDN, founder of Compass Nutrition.

“Full-fat dairy can improve satiety and satisfaction, and for those who tolerate and enjoy it, two to three servings per day can fit well into a balanced diet. A serving might include one cup of milk, six ounces of yogurt, or one ounce of cheese.”

But full-fat dairy foods don’t exist in a vacuum. As cardiologist Kyla M. Lara-Breitinger, MD, MS, told Mayo Clinic, “The relationship between dairy foods and heart health is complex. … It’s difficult to predict the total effect of food based on a single nutrient, especially when you consider that diet as a whole contributes a net effect to overall health.” ^[]

Continuous glucose monitors (CGMs) are becoming mainstream

Chad Larson, NDM, DC, CCN, CSCS, a naturopathic doctor and functional medicine practitioner, says he’s seeing more people without diabetes using continuous glucose monitors (CGMs) to boost their overall wellness and manage their weight.

“These are by far the most validated wearable devices for precision nutrition,” he says. “The ability to pair CGM data with food diary entries allows for the identification of specific patterns of behavior through which practitioners can develop individualized treatment strategies that generic nutritional recommendations could never duplicate.”

For people without diabetes, Dr. Larson says, “Data from nondiabetic CGM users reveal substantial post-prandial glucose variability that standard fasting labs do not measure or account for at all, and this variability is directly correlated with metabolic dysfunction, cognitive function, and energy production.”

Direct-to-consumer (DTC) healthcare isn’t slowing down anytime soon

More and more people are choosing to bypass traditional healthcare systems. AI is largely behind this, powering patient platforms and enabling people to buy medicine with the click of a button.

While this trend isn’t going anywhere, researchers aren’t sure of its long-term impact on patient care. While getting meds through an app may be easy, it could potentially lead to missed diagnoses, overdiagnosis, and overtreatment, according to research published in BMJ Open. ^[]

“We have little insight into impacts on quality of care, health outcomes, health system utilisation and privacy-related ethical concerns," the authors wrote. ^[]
