Amid conflicting guidance, GLP-1 weight-loss trends and recent updates to dietary guidelines, navigating nutrition advice can feel overwhelming.
As weight-loss conversations increasingly focus on medications, some Americans may be looking for more natural ways to quiet what’s often called “food noise.”
Here are some tips to help tune it out.
WEIGHT-LOSS EXPERTS PREDICT 5 MAJOR TREATMENT CHANGES LIKELY TO EMERGE IN 2026
What is food noise?
Food noise can be described as frequent thoughts about food that can sometimes be mistaken as hunger, experts say.

Northwell Health’s The Well describes it as a “steady background loop of food-related thoughts” that can interfere with daily life and decision-making about eating.
This can lead someone to eat excess calories, causing weight gain, obesity and other medical problems like high blood pressure, high cholesterol and sleep apnea, according to the Cleveland Clinic.
DOCTOR WARNS MANY AMERICANS EAT ‘FOOD-LIKE SUBSTANCES,’ NOT REAL FOOD
“It’s a lot of unnecessary, excessive thoughts around food that can be exhausting,” Kat Garcia-Benson, registered dietitian-nutritionist at VNutrition, a wellness brand that offers plant-based dishes and expert nutrition tips, told Fox News Digital.
“You might have thoughts like: ‘I’m craving this,’ ‘When is my next meal?’, ‘What should I eat to be healthier?’, ‘I should eat this,’ or ‘I shouldn’t eat that,’” added the Texas-based expert.
Certain behaviors — such as skipping meals, ignoring hunger clues, relying on rigid food rules and cutting out entire food groups — can worsen food noise. (iStock)
Certain behaviors can worsen food noise. These may include skipping meals, ignoring hunger clues, relying on rigid food rules and cutting out entire food groups, according to Garcia-Benson.
Studies have shown that some medical conditions, like polycystic ovarian syndrome and depression, can also increase food noise, as can stress and inadequate sleep. Certain medications, such as antidepressants, can also exacerbate it.

“It’s also important to note that food noise is not a personal failure or [due to] having a lack of willpower,” Garcia-Benson added. “For many people, it’s a response from years of dieting/food restriction, stress or inconsistent nourishment.”
Drivers of hunger
“The impulse to eat is driven by three core aspects: hunger, satiety, and pleasure or reward,” Dr. Vinita Tandon, chief medical officer of Medi-Weightloss, a physician-supervised weight-loss program based in Tampa, told Fox News Digital.
The body naturally makes a hormone called glucagon-like peptide-1, or GLP-1, which helps to regulate appetite and food intake.
“It’s a lot of unnecessary, excessive thoughts around food that can be exhausting.”
In people with obesity, however, the body’s natural GLP-1 response may be less effective at signaling fullness, Tandon noted.
GLP-1 medications, including Ozempic, can fast-track weight loss by mimicking a natural hormone that suppresses appetite and helps people feel full sooner, the expert said.

They also offer an additional benefit by acting on the brain’s rewards pathway.
When someone eats a brownie, for example, they experience a surge in a “pleasure hormone” known as dopamine, Tandon said. GLP-1 medications blunt this response, so the person feels no differently eating a brownie than when eating a spinach salad.

“We no longer crave those unhealthy, sugary foods because we don’t derive pleasure from them anymore,” she added.
6 tips to tune out food noise
Some triggers of food noise may be internal – like certain hunger hormones that can make us eat more — while others are external, like seeing a favorite snack or getting a whiff of a freshly baked pie.

“[Some] people find that peeling back the layers and building a healthier relationship with food can quiet the food noise, especially when it comes from a lifetime of diet cycling – like moving between restrictive diets and periods of overconsumption,” Garcia-Benson said.
Experts shared the following natural techniques that can help reduce food noise.
No. 1: Keep a “hunger record”
Writing down when your food cravings are loudest — such as when scrolling on your phone — can help you identify any triggers.
Health experts recommend that adults get 25 to 38 grams of fiber per day and at least 0.8 grams of protein per kilogram of body weight, with higher protein intakes often advised for appetite control. (iStock)
No. 2: Increase fiber and protein intake
Research shows that these nutrients help you stay full longer, stimulating natural GLP-1 hormones to send signals to the brain that lessen cravings.
Health experts recommend that adults get 25 to 38 grams of fiber per day and at least 0.8 grams of protein per kilogram of body weight, with higher protein intakes often advised for appetite control.

No. 3: Slow down and be more present when eating
Focusing solely on food and eating mindfully can help to curb appetite, experts say.
Harvard experts recommend eating more slowly and paying attention to each bite — without distractions like phones or TV — to better recognize fullness cues and avoid overeating.
No. 4: Get enough sleep
People who don’t sleep well may have a difficult time being disciplined about food intake the next day. They often crave highly processed and carb-heavy foods to increase their energy, multiple studies have shown.
Health authorities recommend that adults get between seven and nine hours of sleep each night.

No. 5: Manage stress
Chronic stress lowers the production of natural GLP-1 and leads to high cortisol levels, which can lead to weight gain, according to Tandon.

Experts recommend managing chronic stress with mindfulness, meditation and consistent physical activity to help lower cortisol levels and support healthier metabolic function and weight regulation, per Cleveland Clinic.
No. 6: Exercise regularly
Physical activity has been shown to boost GLP-1 levels. Most health authorities recommend that adults aim for at least 150 minutes of moderate-intensity aerobic activity per week and at least two days per week of muscle-strengthening activities.

Heart disease threat projected to climb sharply for key demographic
NEWYou can now listen to Fox News articles!
A new report by the American Heart Association (AHA) included some troubling predictions for the future of women’s health.
The forecast, published in the journal Circulation on Wednesday, projected increases in various comorbidities in American females by 2050.
More than 59% of women were predicted to have high blood pressure, up from less than 49% currently.
The review also projected that more than 25% of women will have diabetes, compared to about 15% today, and more than 61% will have obesity, compared to 44% currently.
As a result of these risk factors, the prevalence of cardiovascular disease and stroke is expected to rise to 14.4% from 10.7%.

Dr. Elizabeth Klodas, a cardiologist and founder of Step One Foods in Minnesota, commented on these “jarring findings.”
“The fact that on our current trajectory, cardiometabolic disease is projected to explode in women within one generation should be a huge wake-up call,” she told Fox News Digital.
NEARLY 90% OF AMERICANS AT RISK OF SILENT DISEASE — HERE’S WHAT TO KNOW
“Hypertension, diabetes, obesity — these are all major risk factors for heart disease, and we are already seeing what those risks are driving. Heart disease is the No. 1 killer of women, eclipsing all other causes of death, including breast cancer.”

Klodas warned that heart disease starts early, progresses “stealthily,” and can present “out of the blue in devastating ways.”
The AHA published another study on Thursday revealing one million hospitalizations, showing that heart attack deaths are climbing among adults below the age of 55.
The more alarming finding, according to Klodas, is that young women were found more likely to die after their first heart attack than men of the same age.
DOCTOR SHARES 3 SIMPLE CHANGES TO STAY HEALTHY AND INDEPENDENT AS YOU AGE
“This is all especially tragic since heart disease is almost entirely preventable,” she said. “The earlier you start, the better.”
Children can show early evidence of plaque deposition in their arteries, which can be reversed through lifestyle changes if “undertaken early enough and aggressively enough,” according to the expert.

Klodas suggested that rising heart conditions are associated with traditional risk factors, like smoking, high blood pressure, high cholesterol, diabetes, obesity and a sedentary lifestyle.

Doctors are also seeing higher rates of preeclampsia, or high blood pressure during pregnancy, as well as gestational diabetes. Klodas noted that these are sex-specific risk factors that don’t typically contribute to complications until after menopause.
The best way to protect a healthy heart is to “do the basics,” Klodas recommended, including the following lifestyle habits.

Klodas especially emphasized making improvements to diet, as the food people eat affects “every single risk factor that the AHA’s report highlights.”
“High blood pressure, high blood sugar, high cholesterol, excess weight – these are all conditions that are driven in part or in whole by food,” she said. “We eat multiple times every single day, which means what we eat has profound cumulative effects over time.”
“Even a small improvement in dietary intake, when maintained, can have a massive positive impact on health,” a doctor said. (iStock)

The doctor also recommends changing out a few snacks per day for healthier choices, which has been proven to “yield medication-level cholesterol reductions” in a month.

“Keep up that small change and, over the course of a year, you could also lose 20 pounds and reduce your sodium intake enough to avoid blood pressure-lowering medications,” Klodas added.
“Women should not view the AHA report as inevitable. We have power over our health destinies. We just need to use it.”

Common vision issue linked to type of lighting used in Americans’ homes
NEWYou can now listen to Fox News articles!
Nearsightedness (myopia) is skyrocketing globally, with nearly half of the world’s population expected to be myopic by 2050, according to the World Health Organization.
Heavy use of smartphones and other devices is associated with an 80% higher risk of myopia when combined with excessive computer use, but a new study suggests that dim indoor lighting could also be a factor.
For years, scientists have been puzzled by the different ways myopia is triggered. In lab settings, it can be induced by blurring vision or using different lenses. Conversely, it can be slowed by something as simple as spending time outdoors, research suggests.
Nearsightedness occurs when the eyeball grows too long from front to back, according to the American Optometric Association (AOA). This physical elongation causes light to focus in front of the retina rather than directly on it, making distant objects appear blurry.
The study suggests that myopia isn’t caused by the digital devices themselves, but by the low-light environments where they are typically used. (iStock)
Researchers at the State University of New York (SUNY) College of Optometry identified a potential specific trigger for this growth. When someone looks at a phone or a book up close, the pupil naturally constricts.
COMMON VISION ISSUE COULD LEAD TO MISSED CANCER WARNING, STUDY FINDS
“In bright outdoor light, the pupil constricts to protect the eye while still allowing ample light to reach the retina,” Urusha Maharjan, a SUNY Optometry doctoral student who conducted the study, said in a press release.

“When people focus on close objects indoors, such as phones, tablets or books, the pupil can also constrict — not because of brightness, but to sharpen the image,” she went on. “In dim lighting, this combination may significantly reduce retinal illumination.”
High-intensity natural light prevents myopia because it provides enough retinal stimulation to override the “stop growing” signal, even when pupils are constricted. (iStock)
The hypothesis suggests that when the retina is deprived of light during extended close-up work, it sends a signal for the eye to grow.
In a dim environment, the narrowed pupil allows so little light through that the retinal activity isn’t strong enough to signal the eye to stop growing, the researchers found.

In contrast, being outdoors provides light levels much brighter than indoors. This ensures that even when the pupil narrows to focus on a nearby object, the retina still receives a strong signal, maintaining healthy eye development.

The team noted some limitations of the study, including the small subject group and the inability to directly measure internal lens changes, as the bright backgrounds used to mimic the outdoors made pupils too small for standard equipment.
Researchers believe that increasing indoor brightness during close-up work could be a simple, testable way to slow the global nearsightedness epidemic. (iStock)
“This is not a final answer,” Jose-Manuel Alonso, MD, PhD, SUNY distinguished professor and senior author of the study, said in the release.

“But the study offers a testable hypothesis that reframes how visual habits, lighting and eye focusing interact.”
The study was published in the journal Cell Reports.
