Researchers found that taking a pasteurized probiotic supplement (called Akkermansia muciniphila) for 3 months showed some promising results for people with prediabetes — a condition where blood sugar is higher than normal but not yet at diabetes levels. In particular, people who naturally had low levels of this beneficial gut bacteria to begin with seemed to benefit the most, showing improvements in how well their body responds to insulin (the hormone that manages blood sugar), as well as reductions in body weight and trunk fat. This is early research and hasn't yet changed treatment guidelines.

A study found that taking a daily supplement made from whole feijoa fruit (a small green fruit rich in natural plant compounds) did not improve fasting blood sugar — the level of sugar in the blood after not eating overnight — or weight loss beyond what a low-calorie diet alone achieved in people at risk for type 2 diabetes. Both groups in the study did see improvements in blood sugar and body weight, but those taking the feijoa powder did not do better than those taking a placebo, suggesting the diet itself was doing the heavy lifting. For someone with prediabetes, this matters because it hints that feijoa supplements may not add extra benefit on top of a healthy eating plan, though the full picture of results was not yet reported. This is early research and hasn't yet changed treatment guidelines.

Researchers found that people taking a diabetes medication like Ozempic or Victoza may lose more body fat compared to other treatments, but the findings were mixed and inconsistent across studies. Interestingly, questions remain about whether these medications also affect muscle — both how much muscle people have and how well it functions — which matters because losing muscle along with fat can affect strength and overall health. This is early research and hasn't yet changed treatment guidelines.

PubMed (Open Access Guidelines) · November 1, 2026
Researchers found that taking short activity breaks — especially brief walks — during long periods of sitting helped lower blood sugar levels after meals in adults, particularly those with type 2 diabetes. Breaking up sitting time every 15 to 20 minutes seemed to produce the biggest improvements in blood sugar control, meaning the body didn't have to work as hard to manage sugar in the bloodstream after eating. This is early research and hasn't yet changed treatment guidelines.

PubMed · October 16, 2026
Researchers found that physical exercise may boost the body's natural production of tiny proteins made inside cells — called mitochondrial-derived peptides — that help the body manage energy and respond to stress. In people with type 2 diabetes, higher levels of these proteins were linked to better blood sugar control and improved sensitivity to insulin, meaning the body may use insulin more effectively. This is early research and hasn't yet changed treatment guidelines.

A study found that when people with obesity and early metabolic problems (like prediabetes or excess fat in the liver) lost about 10% of their body weight, the type of diet they used made a difference in some health outcomes. People who followed a very-low-carbohydrate (ketogenic) diet saw greater improvements in liver health and blood sugar control compared to those who followed a Mediterranean or very-low-fat plant-based diet — even though all three groups lost the same amount of weight. This is early research and hasn't yet changed treatment guidelines.

PubMed · October 1, 2026
Researchers found that adults over 55 who received monthly one-on-one nutrition counseling over three months lost about 4–6 centimeters (roughly 2 inches) from their waist size and also saw improvements in body weight and blood sugar control. People who also used a digital app and wearable devices moved more each week — about 55 extra MET-minutes, which is roughly equivalent to adding 10–15 minutes of brisk walking daily — compared to those who only had counseling. The nutrition counseling alone drove most of the health improvements, while the digital tools helped people with obesity get more physically active but didn't add extra metabolic benefits on top of that in just three months.

Researchers found that tirzepatide (sold as Zepbound or Mounjaro) helped people with obesity lose about 4 more pounds and a greater percentage of body weight compared to semaglutide — a diabetes medication like Ozempic or Victoza — also used for weight loss. Tirzepatide was also better at improving blood sugar level (A1C), and more people taking it reached meaningful weight-loss milestones like losing 10%, 15%, or 20% of their body weight. However, serious side effects were reported more often with tirzepatide, so anyone considering these medications should talk through the risks and benefits with their doctor. This is early research and hasn't yet changed treatment guidelines.
Ask your doctor: Ask the doctor whether tirzepatide might help the patient lose more weight than semaglutide, based on recent research comparing the two medications.

Researchers found that adults with high blood pressure who received diet counseling combined with a digital health platform and wearable devices (like fitness trackers) saw greater improvements in physical activity levels and a larger drop in a key blood pressure measure compared to those who received diet counseling alone. In other words, adding technology to traditional healthy lifestyle support appeared to give people an extra boost in managing their high blood pressure. This is early research and hasn't yet changed treatment guidelines.

PubMed · September 30, 2026
Researchers found that eating a lot of sugar is consistently linked to a higher risk of 18 different health problems, with the strongest evidence connecting sugar intake to type 2 diabetes, obesity, serious heart problems like heart attacks or strokes, and early death. For people with type 2 diabetes especially, this matters because sugar consumption may worsen blood sugar control and raise the chances of complications beyond diabetes alone. This is early research and hasn't yet changed treatment guidelines.

ScienceDaily · September 24, 2026
A press release highlights new findings suggesting that children taking a diabetes medication like Ozempic or Victoza for weight loss or blood sugar concerns may be at risk of not getting enough key nutrients. Researchers found that nearly 1 in 6 young patients developed a nutritional deficiency — such as low vitamin D — within a year of starting the medication. This appears to be a safety concern that hasn't received much attention yet, and families may want to be aware of it.
Ask your doctor: Ask the doctor whether the patient should get blood tests to check for vitamin D or other nutritional deficiencies if the patient starts taking a GLP-1 medication like Ozempic or Saxenda.

PubMed · September 22, 2026
Researchers found that people who eat more ultra-processed foods — think packaged snacks, fast food, and ready-made meals with long ingredient lists — were more likely to develop serious health problems, including serious heart problems like heart attacks or strokes, diabetes, and certain cancers, compared to people who ate less of these foods. For every additional 100 grams of ultra-processed food eaten per day (roughly a small bag of chips or a couple of processed snack bars), the risk of diabetes or metabolic problems — a cluster of conditions that raise the chances of heart disease and diabetes — crept up a little more. This is early research and hasn't yet changed treatment guidelines.
Medications

A press release discusses Ozempic and similar medications, highlighting that while these drugs are well known for helping with blood sugar control, weight, and reducing serious heart problems like heart attacks or strokes in people with type 2 diabetes, researchers found little evidence that they also improve mental health, employment, relationships, or overall sense of well-being. This suggests that the broader life benefits of these medications may be more limited than their physical health effects.

Scientists found that black and green Japanese rice contain special types of fats not commonly found in regular white rice, and that these colorful varieties may be broken down more slowly during digestion — which could help keep blood sugar levels steadier after a meal. For people with type 2 diabetes, steadier blood sugar after eating is an important part of managing the condition. This is early research and hasn't yet changed treatment guidelines.

Researchers found that Coptidis Rhizoma — a traditional herbal remedy derived from a plant root — may help improve blood sugar level (A1C), body weight, and LDL cholesterol (the 'bad' kind that can clog arteries) in people with type 2 diabetes, obesity, or high cholesterol, based on a combined analysis of 19 smaller studies involving over 1,700 patients. The herb appeared to work best when used alongside standard treatments, not as a replacement for them. This is early research and hasn't yet changed treatment guidelines.

A study found that people with prediabetes who used an AI-powered smartphone app more often were more likely to lose enough weight and increase their physical activity to lower their risk of developing diabetes. Interestingly, older adults and those with a lower starting body weight tended to use the app most consistently, which researchers found surprising since younger people are often assumed to be more comfortable with technology. This is early research and hasn't yet changed treatment guidelines.

Researchers found that a probiotic supplement called Wilac D001 (WIKIM51) may help reduce belly fat and improve blood sugar control in overweight adults over 12 weeks, compared to a placebo (a dummy pill with no active ingredient). The supplement appeared to work partly by boosting levels of a natural gut hormone — the same type of hormone that medications like Ozempic or Victoza are designed to mimic — which helps the body manage blood sugar and appetite. This is early research and hasn't yet changed treatment guidelines.

A study found that limiting meals to a 10-hour window each day — for example, eating only between 9am and 7pm — did not produce noticeably different results in appetite or inflammation compared to people who ate over a longer 16-hour window, as long as both groups consumed the same number of calories. Both groups lost a similar amount of weight and reported feeling less hungry and more in control of their eating habits by the end of the 12 weeks. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · September 1, 2026
Researchers found that people who stopped taking a diabetes medication like Ozempic or Victoza (semaglutide) or a similar drug called tirzepatide regained weight fairly quickly after stopping — about half of the weight they had lost came back within roughly seven and a half months, and most people returned close to their starting weight within about fifteen months. The study also found that people who lost more weight during treatment tended to regain it faster afterward, possibly because the body works harder to return to its previous weight. This is early research and hasn't yet changed treatment guidelines.

A clinical trial — where researchers compare different approaches in a controlled setting — found that a ketogenic (very low-carb, high-fat) diet reduced liver fat by 67% in people with fatty liver disease, compared to about 45% for Mediterranean and low-fat diets, even though all groups lost a similar amount of weight. On top of that, roughly half the people following the keto diet no longer met the criteria for prediabetes (a warning sign that blood sugar is creeping too high) after four to five months. This is early research and hasn't yet changed treatment guidelines.

Researchers found that just six 30-second sprints changed nearly a quarter of the proteins in the bloodstream and over 200 other chemical markers — far more than 90 minutes of moderate cycling did. Some of those proteins are linked to lower risks of obesity and type 2 diabetes, which could matter for people managing their blood sugar. This is early research and hasn't yet changed treatment guidelines.
What's New
JAMA · August 4, 2026
Researchers found that people taking a diabetes medication like Ozempic or Victoza may be more likely to experience changes in their sense of smell or taste — meaning foods might smell or taste different, weaker, or even unpleasant. This could matter for people with type 2 diabetes because these medications are widely used, and changes in smell or taste can affect appetite, enjoyment of food, and overall quality of life. This is early research and hasn't yet changed treatment guidelines.
Ask your doctor: Ask the doctor whether the patient should know about reports that GLP-1 medications like Ozempic or Wegovy might affect the ability to smell or taste food.
Lifestyle
PubMed · August 1, 2026
Researchers found that eating a low-carbohydrate diet built around plant foods — think vegetables, nuts, legumes, and whole grains, while cutting back heavily on bread, sugar, and starchy foods — helped people with obesity or related health conditions lose roughly 5 to 7 kilograms (about 11 to 15 pounds). The same approach also lowered harmful LDL cholesterol and improved blood sugar level (A1C), which measures how well the body has been managing blood sugar over the past few months. These results came from seven studies involving nearly 1,000 adults and lasted anywhere from about one month to one year.

Researchers found that diabetes isn't just about having too much fat — it can also happen when the body loses healthy fat tissue that it actually needs to function well. When fat cells become damaged and inflamed, they can stop working properly and disappear, which throws off the body's metabolism (the system that turns food into energy). This is early research and hasn't yet changed treatment guidelines.

A press release describes early findings suggesting that a diabetes medication like Ozempic or Victoza, taken in pill form, may reduce pleasure-driven eating by calming a part of the brain linked to cravings and reward. For people with obesity, this is interesting because it hints that these medications might work not just on metabolism but also on the urge to eat for pleasure rather than hunger. This is early research in mice and hasn't yet changed treatment guidelines.

A study found that people with obesity who limited all their eating to an eight-hour window each day — for example, eating only between noon and 8 p.m. — kept more weight off even a full year after the 12-week program ended, compared to people who ate on their usual schedule. The benefit showed up whether people chose an earlier or later eight-hour window, though an earlier eating window seemed especially good at helping people hold on to fat loss specifically. Researchers found this approach helped people with obesity maintain their results over time, not just while they were actively following the program.

PubMed · July 16, 2026
Researchers found that smartphone and app-based tools that send people personalized nudges or tips at just the right moment — like when they're most likely to make a poor food choice — may help people eat healthier in their everyday lives. For someone managing obesity, this kind of real-time, tailored support could make it easier to build better habits without relying on memory or willpower alone. This is early research and hasn't yet changed treatment guidelines.
What's New
JAMA · July 14, 2026
Researchers found that eating a lot of ultraprocessed foods — things like packaged snacks, fast food, and ready-made meals that are heavily manufactured and contain many added ingredients — may be linked to a higher risk of serious heart problems like heart attacks or strokes, as well as a greater chance of death overall. For people with type 2 diabetes, who are already at higher risk for heart-related complications, this connection could be especially important to be aware of. This is early research and hasn't yet changed treatment guidelines.

ScienceDaily · July 10, 2026
A press release describes findings suggesting that eating a Mediterranean-style diet — one that is low in protein, particularly from animal sources like meat and dairy — may help reduce body fat and lower the chances of obesity and Type 2 diabetes. The diet also kept levels of a building block found in animal protein, called methionine, just low enough to appear beneficial. Researchers saw these effects in mice and also found a pattern in human data linking less animal protein to better outcomes.
Medications
ScienceDaily · July 9, 2026
A press release highlights a rise in accidental dosing mistakes involving Ozempic and Wegovy — medications used to help manage weight and blood sugar — leading to a surge in calls to poison control centers. These incidents appear to be unintentional errors, such as taking the wrong dose or dosing too often, rather than deliberate misuse. Experts suggest that clearer education about how to use these weekly medications correctly could help prevent many of these situations.
Ask your doctor: Ask the doctor whether the patient needs clear written instructions about how often to inject Wegovy and how to increase the dose slowly to avoid accidental overdose mistakes.
