This study looked at what happened when overweight college-age women took different amounts of caffeine before doing 40 minutes of moderate-paced treadmill walking — specifically walking at the speed where their bodies burned the most fat. The researchers found that a moderate caffeine dose (roughly 3–5 mg per kilogram of body weight — so about 200–340 mg for a 150-pound person, roughly the amount in 2–3 cups of coffee) taken before that walk increased the amount of fat the body burned during exercise compared to no caffeine, without raising heart rate or blood pressure the way the higher doses did. The evidence is early and was tested in a small group of young women, so it's worth discussing with your doctor before making any changes, especially since caffeine affects everyone differently.
Ask your doctor: Ask the doctor whether drinking caffeine before I exercise might help the patient's body burn more fat during workouts.

Researchers found that men with obesity who combined a plant-based supplement called fisetin with a 12-week exercise program — mixing strength training and cardio — showed notable improvements in inflammation and blood sugar control compared to those who only exercised or only took the supplement. Specifically, levels of a natural inflammation-calming molecule in the body called Maresin-1 went up, while markers of inflammation and insulin resistance (a sign the body is struggling to manage blood sugar properly) went down most in the group that did both. This is early research and hasn't yet changed treatment guidelines.
Medications
PubMed · December 1, 2026
This study compared two weight-loss medications — tirzepatide (brand name Mounjaro or Zepbound) and semaglutide (brand name Wegovy or Ozempic) — in people with obesity or excess weight. Researchers found that tirzepatide not only helped people lose more weight and reduced the risk of serious health problems like serious heart problems like heart attacks or strokes, but it was also estimated to cost less overall when factoring in healthcare and broader life costs. This appears to be a new finding about how these two medications compare, rather than a safety update or guideline change.
Ask your doctor: Ask the doctor whether tirzepatide might work better for the patient's weight loss than semaglutide, since studies show it helped people lose more weight.

PubMed (Open Access Guidelines) · December 1, 2026
Researchers found that whole-body vibration training — a type of exercise where people stand or move on a platform that vibrates — helped lower resting blood pressure in adults. The effect was especially noticeable in people who already had higher blood pressure or who were overweight, with their top blood pressure number dropping by more than 11 points on average in those groups. This is early research and hasn't yet changed treatment guidelines.
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.

PubMed (Open Access Guidelines) · July 1, 2026
Researchers found that people with type 2 diabetes tend to lose less weight on a diabetes medication like Ozempic or Victoza compared to people who have obesity but not diabetes — but when factors like age, body weight, and other health conditions were accounted for, type 2 diabetes itself may not be the direct reason for that difference. This suggests the gap in weight loss might be explained by other characteristics common in people with type 2 diabetes, such as high blood pressure or differences in starting body weight, rather than diabetes acting as a barrier on its own. This is early research and hasn't yet changed treatment guidelines.
What's New
The Lancet · June 8, 2026
Researchers found that pill-form versions of a diabetes medication like Ozempic or Victoza — which were previously only available as injections — could open up new options for treating both type 2 diabetes and obesity, since weight loss is now seen as an important part of managing type 2 diabetes. This matters because a daily pill might be easier for some people to take than a weekly injection. This is early research and hasn't yet changed treatment guidelines.
Medications
The Lancet · June 8, 2026
Researchers found that a daily oral medication called elecoglipron — a diabetes medication like Ozempic or Victoza, but taken as a pill rather than an injection — helped people with obesity or overweight lose a meaningful amount of weight. The side effects seen were similar to what's already known about this type of medication. This is an early-stage finding, and researchers say the results are promising enough to move forward with larger studies to learn more.
What's New
The Lancet · June 6, 2026
Researchers found that tirzepatide, a newer diabetes medication that works on two hormone pathways at once, did a better job of lowering blood sugar level (A1C) and helping people lose weight compared to semaglutide — a well-known diabetes medication like Ozempic or Victoza — in people with type 2 diabetes. The idea behind this research is that targeting more than one hormone signal in the body might work better than targeting just one, which could matter a lot for people trying to manage both their blood sugar and their weight. This is early research and hasn't yet changed treatment guidelines.
Lifestyle
PubMed · June 6, 2026
Researchers found that postmenopausal women with overweight or obesity who did regular aerobic exercise — things like brisk walking, cycling, or swimming — lost an average of about 2 pounds of body weight and nearly 2 pounds of body fat, and trimmed roughly 3/4 of an inch from their waist compared to women who did not exercise. The study also found a 'dose-response' pattern, meaning the more aerobic exercise women did, the greater the changes in their body composition tended to be. These findings are based on 16 studies involving over 1,500 participants, though researchers rated the overall confidence in some of the results as low to moderate, so the true effect could vary from person to person.
What's New
ScienceDaily · June 3, 2026
A press release describes an experimental pill being developed for type 2 diabetes and obesity that works differently from a diabetes medication like Ozempic or Victoza — instead of reducing appetite, it targets the muscles to help the body burn fat and manage blood sugar control, while keeping muscle mass intact. Early results suggest it appears to be safe and well tolerated by patients. Because this is a press release about early-stage research and not yet a published study, it's worth watching but hasn't yet changed treatment guidelines.
Lifestyle
JAMA · June 2, 2026
A study explored how exercise fits into weight loss plans, especially for people taking a diabetes medication like Ozempic or Victoza, and found that getting patients to stick with regular exercise is a real challenge for doctors. Researchers looked at strategies that could help people stay consistent with physical activity, whether or not they're on these medications. This matters because exercise likely plays an important supporting role in weight management, and patients might want to ask their doctor what realistic, personalized movement goals could look like for them.
Lifestyle
AHA Guidelines · June 1, 2026
A study found that regularly moving your body — through activities like walking, cycling, or other exercise done on a consistent basis — improves several health measures in people with overweight or obesity, including blood pressure, how well the body responds to insulin (which helps manage blood sugar), cholesterol levels, and heart and lung fitness. Importantly, researchers found these benefits happen regardless of whether a person loses weight. This means that getting active regularly can improve how the body works on the inside, even when the number on the scale doesn't change.
Lifestyle
AHA Guidelines · June 1, 2026
Researchers found that adults with obesity who exercise regularly — meaning consistent physical activity as a habit, not just occasional movement — can improve their high blood pressure, cholesterol, and how well their body handles blood sugar, even if the number on the scale doesn't change. The benefits came from the activity itself, not from losing weight. This suggests that staying active has real health value for people with obesity beyond just burning calories.

PubMed · June 1, 2026
This research combined data from 23 studies and found that people with type 2 diabetes — and adults generally — who closely followed the Planetary Health Diet (an eating pattern built around vegetables, fruits, whole grains, legumes like beans and lentils, and nuts, with little red meat or processed food) had about 17–18% lower chances of death or serious heart problems like heart attacks or strokes. The benefit wasn't all-or-nothing: meaningful risk reductions appeared once people reached a moderate-to-high level of the diet, suggesting that gradually eating more plants and less processed meat — even starting with one meal today — may matter. The researchers note these studies show a strong link but can't yet prove the diet directly causes these better outcomes, so this is promising but not the final word.

PubMed · June 1, 2026
This large analysis of 18 studies found that non-surgical weight loss approaches — things like calorie-reduced eating plans and structured exercise — meaningfully reduced how often people with obesity stopped breathing during sleep (a condition called sleep apnea, where breathing repeatedly pauses at night). People following these programs also lost an average of about 14 pounds, shed inches from their waist, and saw their high blood pressure drop noticeably. The evidence was strongest over the short to medium term, meaning the benefits were clearest in the earlier months of sticking with the changes.

PubMed (Open Access Guidelines) · June 1, 2026
Researchers found that a diabetes medication like Ozempic or Victoza may do more than manage blood sugar — it might also help reduce anxiety. In animal studies, the medication consistently calmed anxiety-like behaviors, and in human studies, people taking it showed some signs of lower anxiety and reduced risk of suicidal thoughts, though the human results were mixed. This is early research and hasn't yet changed treatment guidelines.

PubMed · June 1, 2026
A study found that people with prediabetes — a stage where blood sugar is higher than normal but not yet at diabetes levels — who added fiber supplements (from potato fiber and sugar beet pectin) to a high-protein diet showed early signs of changes in brain activity related to food cravings, particularly in the amygdala, a part of the brain involved in emotional responses and desire for food. The idea behind this is that fiber is broken down in the gut and may send signals to the brain that help people feel fuller and less drawn to high-calorie foods, which could potentially help with weight and blood sugar control. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · June 1, 2026
Researchers found that combining two medications — cagrilintide and a diabetes medication like Ozempic or Victoza (semaglutide) — helped people with obesity lose significantly more weight than taking the diabetes medication alone, in a study involving people in Japan and Taiwan. Both medications were given as once-weekly injections over about 16 months, alongside lifestyle changes. This is early research and hasn't yet changed treatment guidelines.
Ask your doctor: Ask the doctor whether the patient might benefit from taking cagrilintide and semaglutide together instead of semaglutide alone for weight loss.
What's New
PubMed · June 1, 2026
A study found that a structured weight loss program helped some people with type 2 diabetes go into remission — meaning their blood sugar returned to a normal range without medication — and that this approach actually saved money over five years compared to standard care, largely because participants needed fewer hospital stays and less medication. Researchers found that the program cost about £1,691 per person but led to roughly £2,091 in healthcare savings per person, making it cost-effective over the long run. People with type 2 diabetes may want to ask their doctor whether a structured, low-calorie weight management program could be a suitable option for them.
What's New
PubMed · June 1, 2026
A study found that when people with obesity lost weight using diabetes medications like Ozempic or Victoza (including newer versions that work two ways at once), roughly a quarter to a third of the weight they lost came from muscle rather than fat — a pattern that was similar to what happened with diet and exercise changes alone. The most encouraging finding was that adding resistance training (such as weightlifting or strength exercises) to a lifestyle program led to the least amount of muscle loss during weight loss, compared to any other approach studied. For someone with obesity, this matters because keeping muscle while losing weight helps maintain strength and long-term health. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · June 1, 2026
Researchers found that among several diabetes medications like Ozempic or Victoza used for weight loss, tirzepatide (sold as Mounjaro or Zepbound) stood out as the most effective at helping people with obesity lose a meaningful amount of weight — whether or not they also had Type 2 diabetes — with people being up to 14 times more likely to lose 10% or more of their body weight compared to those taking a placebo (a dummy treatment with no active medicine). This matters because losing even 5–10% of body weight can significantly improve health outcomes for people living with obesity, and this large review pooled results from 127 studies and nearly 59,000 participants, giving it more weight than a single study alone. This is early research and hasn't yet changed treatment guidelines.
Ask your doctor: Ask the doctor whether the patient might be a candidate for a GLP-1 medication like semaglutide or tirzepatide, since research shows these drugs help people lose weight even without diabetes.
Guidelines
PubMed · June 1, 2026
According to Italian Society of Gastroenterology (SIGE) guidelines, a diabetes medication like Ozempic or Victoza can be safely used by people with type 2 diabetes or obesity who also have liver or digestive conditions, and there is no need to stop taking it before a routine stomach scope procedure. The guidelines also note that these medications do not appear to raise the risk of cancers in the stomach, colon, or pancreas, and may even lower the chances of a specific type of liver cancer. People taking this type of medication may experience mild, temporary digestive side effects — like nausea or stomach upset — and a higher chance of developing gallstones (hard deposits that form in the gallbladder), but serious digestive complications do not appear to be a concern.

A study found that for people with metabolic syndrome — a cluster of conditions including high blood pressure, excess belly fat, and blood sugar problems — high-intensity interval training (short bursts of hard effort followed by rest) was the most effective type of exercise for lowering blood pressure, outperforming steady aerobic exercise, strength training, and mind-body practices like yoga or tai chi. The benefits were especially noticeable in people who already had high blood pressure and in those who kept up their exercise program for 16 weeks or longer. This is early research and hasn't yet changed treatment guidelines.
Lifestyle
PubMed · June 1, 2026
A study found that adults with high blood pressure who were overweight or obese saw notable drops in a hormone called leptin — which, when too high, may make high blood pressure worse — after 16 weeks of combining a calorie-reduced diet with supervised aerobic exercise twice a week. The exercise group saw leptin fall by about 36%, while the diet-only advice group saw a 23% drop, though both groups' levels crept back up to where they started after six months without the program. Researchers found that body weight relative to height was the strongest factor linked to leptin levels across all participants.

PubMed · June 1, 2026
Researchers found that people who had certain health conditions before weight-loss surgery — including a mental health condition, type 2 diabetes, or sleep apnea — tended to lose slightly less weight after the surgery compared to people without those conditions. On the other hand, having high blood pressure or high cholesterol before surgery didn't seem to make much of a difference in how much weight people lost. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · June 1, 2026
Researchers looked at data from nearly 48,000 people with a type of heart failure called heart failure with preserved ejection fraction (HFpEF) — where the heart pumps normally but is too stiff to fill properly — who also had obesity. They examined whether tirzepatide, a diabetes and weight-loss medication that works similarly to a diabetes medication like Ozempic or Victoza, helped reduce serious heart problems like heart attacks or strokes compared to standard care. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · June 1, 2026
Researchers found that people with moderate-to-severe sleep apnea tend to have lower levels of a natural gut hormone (called GLP-1) that helps regulate blood sugar, and that taking a diabetes medication like Ozempic or Victoza may help reduce the number of breathing interruptions during sleep, improve blood sugar control, and lower body weight in people who have sleep apnea alongside obesity or diabetes. This could matter because it suggests there may be a biological link between sleep apnea and blood sugar regulation that doctors might one day be able to target with existing medications. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · June 1, 2026
A study found that women who had a type of weight-loss surgery called gastric bypass experienced significant changes in hunger-related hormones — natural chemical messengers in the body that help control appetite — and these changes were linked to eating less, feeling less hungry, and better blood sugar control over the following year. Researchers also found that after surgery, participants showed improved ability to resist food cravings mentally, suggesting the surgery may affect both the body and the brain's relationship with food. This is early research and hasn't yet changed treatment guidelines.
Lifestyle
PubMed · June 1, 2026
Researchers found that eating red pepper — specifically the compound that makes it spicy, called capsaicin — at amounts you'd normally use in cooking may help the body burn more fat during a period of eating less than usual. When people cut their calories, the body naturally tries to slow down its calorie burning to compensate, which makes losing weight harder; the study looked at whether red pepper could reduce that slowdown. The results suggested that including red pepper across meals showed some promise for supporting fat burning, though findings on hunger and overall calorie intake were mixed across the 24 studies reviewed.
