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.

Researchers found that migrant women from lower-income countries living in wealthier countries have a higher chance of developing diabetes during pregnancy or type 2 diabetes overall. A collection of studies looked at programs designed specifically for these women — including nutrition guidance in their own language, culturally familiar food choices, and community-based physical activity — lasting anywhere from 6 weeks to 12 months. These tailored programs were linked to improvements in eating habits, physical activity levels, and blood sugar control (A1C) among the women who took part.

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 taking zinc supplements may help improve blood sugar control and reduce insulin resistance — meaning the body may respond better to insulin — in people with diabetes or prediabetes. The analysis of 18 studies also found reductions in inflammation markers, which is the body's internal stress response that can worsen diabetes over time, though one finding showed a small rise in LDL ('bad') cholesterol whose real-world importance is still unclear. This is early research and hasn't yet changed treatment guidelines.
Ask your doctor: Ask the doctor whether the patient should take zinc supplements to help with blood sugar control and reduce inflammation, since studies suggest zinc supplementation might improve these things in people with type 2 diabetes.

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.

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.

PubMed (Open Access Guidelines) · September 1, 2026
Researchers found that different diabetes medications can have very different effects on body composition — meaning how much of a person's body is fat versus muscle. Among the medications studied, tirzepatide (a diabetes medication like Ozempic or Victoza, but targeting two hormones) produced the greatest reduction in body fat, while also causing some loss of lean muscle mass. This matters for people with type 2 diabetes because losing muscle alongside fat may affect strength and long-term health, so the type of medication chosen could make a difference beyond just blood sugar control. 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.

Researchers found that adults with prediabetes — meaning blood sugar that is higher than normal but not yet at diabetes levels — who followed an intensive lifestyle program or took the medication metformin were less likely to develop multiple serious chronic conditions at the same time compared to those who received a placebo (an inactive treatment). Having two or more chronic conditions at once, sometimes called multimorbidity, can make health much harder to manage and affects quality of life significantly. This is early research and hasn't yet changed treatment guidelines.

Researchers found that dentist offices might be a surprisingly effective place to spot undiagnosed type 2 diabetes — by combining a simple risk questionnaire, a gum health check, and a small finger-prick blood test to measure blood sugar level (A1C). Across 21 studies reviewed, between 20% and 66% of people tested were flagged as potentially having undetected diabetes, suggesting that routine dental visits could help catch a condition that often goes unnoticed for years. This is early research and hasn't yet changed treatment guidelines.

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.

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 people with type 2 diabetes appear to have a higher risk of serious gum disease, tooth loss, and other oral health problems — and that poor oral health may in turn make blood sugar control harder to manage. This two-way relationship suggests that taking care of teeth and gums might matter more for people with diabetes than is currently recognized in most care plans. This is early research and hasn't yet changed treatment guidelines.

Researchers found that carob — a Mediterranean plant used in foods and supplements — may help improve blood sugar control and insulin response in people with type 2 diabetes or prediabetes (a stage where blood sugar is higher than normal but not yet in the diabetes range). Solid foods made with carob seemed to produce smaller blood sugar spikes after meals compared to regular carbohydrate-based foods, while carob in powder or liquid form showed less consistent results. This is early research and hasn't yet changed treatment guidelines.

A study found that taking melatonin — a popular sleep supplement — may worsen blood sugar control in people who carry a specific gene variant linked to a higher risk of type 2 diabetes. In these individuals, melatonin appeared to reduce the body's early insulin response, which is the quick burst of insulin the body releases right after blood sugar rises — making it harder for the body to manage blood sugar effectively. This is early research and hasn't yet changed treatment guidelines.

A study found that a short, 4-week diabetes prevention program — run by non-medical community workers in just six one-hour sessions — helped people with prediabetes (blood sugar levels in the warning zone before type 2 diabetes develops) improve their blood sugar level (A1C), lose some weight, and slim their waistline, with those benefits lasting a full year after the program ended. The program also helped participants walk farther and make lasting improvements to their eating and exercise habits. This is early research and hasn't yet changed treatment guidelines.

A study found that for people with prediabetes, losing or gaining weight had a bigger effect on blood sugar levels (A1C) in South Asian adults than in White European adults — roughly 1.5 times greater for every 11 pounds of weight change. This suggests that even small shifts in weight may matter more for blood sugar control in South Asian individuals at risk of developing type 2 diabetes. This is early research and hasn't yet changed treatment guidelines.

Researchers found that people who stayed physically active over many years — or who went from being inactive to becoming more active — were significantly less likely to develop type 2 diabetes compared to those who stayed inactive. In fact, people who were consistently active over time had nearly half the risk of developing type 2 diabetes. Interestingly, the same benefit was not clearly seen for high blood pressure, where the differences between active and inactive groups were smaller and not strong enough to be considered definitive. This is early research and hasn't yet changed treatment guidelines.

Researchers found that people with prediabetes — a condition where blood sugar levels are higher than normal but not yet at diabetes levels — were more likely to stick to healthy lifestyle changes if they were retired or unemployed, possibly because they had more flexibility in their daily schedules. The study also found that people with lower incomes often struggled to eat healthily due to the cost of food, even when they wanted to make changes. This is early research and hasn't yet changed treatment guidelines.

A study found that limiting the hours of the day during which people eat — sometimes called time-restricted eating — may help improve blood sugar control in people with prediabetes or type 2 diabetes. Researchers looked at results from ten separate studies involving nearly 600 people and found this eating pattern, which typically means fitting all meals into a window of 12 hours or less, showed promising effects on blood sugar levels (A1C) and related markers. This is early research and hasn't yet changed treatment guidelines.

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.

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.

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.

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.

Researchers found that taking magnesium supplements by mouth did not significantly lower insulin resistance — a condition where the body struggles to use insulin properly — in people with diabetes or pre-diabetes overall, but people who started with low magnesium levels in their blood did seem to benefit more than those with normal levels. This suggests that magnesium supplements might matter most for people who are already running low on magnesium, which is something worth discussing with their doctor. This is early research and hasn't yet changed treatment guidelines.
Medications
ScienceDaily · July 7, 2026
A new once-daily pill called orforglipron was tested against oral semaglutide — the pill version of the medication behind Ozempic — and helped people with type 2 diabetes lose more weight and improve their blood sugar control. Unlike Ozempic, which is an injection, orforglipron is a pill that doesn't need to be refrigerated or taken at a specific time around meals, making it potentially easier to use. It's also less expensive to produce, which could mean more people around the world might one day be able to access it.
