To reverse prediabetes, you don't need to lose fat, just shift it
2025-10-14

To reverse prediabetes, you don't need to lose fat, just shift it

Individuals with prediabetes, which involves elevated blood glucose (sugar) levels that do not meet the criteria for a diabetes diagnosis, are at a very high risk of progressing to diabetes. Clinical guidelines for delaying and preventing type 2 diabetes in individuals with prediabetes emphasize the importance of weight loss using lifestyle interventions or medications. A recent study showed that lifestyle interventions could lead to the normalization of glucose regulation in the absence of weight loss, and such a reversal of prediabetes was sufficient to reduce future risk of type 2 diabetes. These results suggest that clinical guidelines for type 2 diabetes prevention should also focus on normalizing blood glucose control in addition to achieving weight loss targets.

Rheumatoid arthritis silently starts years before pain, study finds

Rheumatoid arthritis is a chronic autoimmune condition that cannot be cured but can be treated to prevent its progression. Individuals at risk of developing rheumatoid arthritis can be identified 3-5 years prior to symptom onset based on autoantibody levels, but only 30-60% of individuals expressing these autoantibodies develop this condition. A recent study has identified changes in the immune profile or signature of individuals at risk for developing rheumatoid arthritis as they progress in the disease. These findings could help with detecting rheumatoid arthritis early and developing more effective preemptive therapies.

A new study in mice found that a ketogenic diet did not accelerate the aging of females, although it did cause males to age more rapidly. The authors of the study found that the presence of estrogen in the female mice blocked the aging effect of the diet. When males were treated with estrogen, estradiol, and antioxidants, the rapid-aging effects of the diets decreased. Further study is required to determine if these effects translate to humans.

Why potassium supplements might help lower heart failure risk

A new trial investigating high-normal serum potassium levels for people at high risk of ventricular arrhythmias delivered promising results. Compared to a control group, people with these elevated potassium levels fared better over the approximately 3 years of the trial. Too little potassium is bad for the heart, and so is too much. The trial suggested a new sweet spot for at-risk heart patients.

Beta-blockers may be harmful for women with some heart conditions

Beta-blockers are a type of medication used after heart attacks. A recent study suggests that using beta-blockers does not improve certain outcomes after heart attacks where the left ventricular ejection fraction is preserved. Further analysis suggests that beta-blocker use may be harmful for women, especially for those who take beta-blockers at higher doses and for women who have preserved left ventricular ejection fraction.

Routine eye exams may help spot early signs of Alzheimer's

One way scientists think Alzheimer’s disease may be detected early is through eye health. Specifically, scientists have been looking into the retina and its blood vessels in hopes that they could help identify changes that are also occurring in the brain. Results of a recent mouse study suggest distinct vascular changes in the eyes and brain occur at the same time, and that closer eye examination could ultimately help doctors detect Alzheimer’s and related dementias sooner.

2025-08-31

Low-calorie Mediterranean diet and exercise may help lower diabetes risk

About one in every nine adults around the world lives with diabetes, with 90% of them having type 2 diabetes. Past studies show that certain lifestyle factors can help lower a person’s risk for type 2 diabetes, such as exercising regularly and eating a healthy diet like the Mediterranean diet. A new study has found that a combination of following a calorie-restricted Mediterranean-style diet, plus moderate exercise and following a weight-loss program, is a more effective way to lower type 2 diabetes risk compared to only following the Mediterranean diet.

22 almonds a day may help prolong your health span, study finds

A person’s oxidative health refers to their body’s ability to keep a good balance of free radicals and antioxidants that when imbalanced, could damage body cells. Oxidative stress can be caused by a number of lifestyle factors, including eating an unhealthy diet. Past studies show that eating certain foods high in antioxidants, like nuts, may help lower a person’s risk for oxidative stress. Now a new study says that eating about 2 ounces of almonds a day may help lower oxidative stress and improve oxidative health, thus prolonging health span.

For better weight control in diabetes, turmeric may be the answer
2025-08-24

For better weight control in diabetes, turmeric may be the answer

Type 2 diabetes is a major global health concern — in 2017, around 6.28% of the world’s population lived with the condition, a proportion that is expected to rise to 7% by 2030. There are several treatments for the condition, but the global cost of treating type 2 diabetes is projected to be more than $1 trillion by 2030. A new study has found that turmeric, or its active component curcumin, may help people with prediabetes or type 2 diabetes lose weight, potentially reducing their need for costly medications.

COVID tied to faster blood vessel aging, especially in women

Since the start of the COVID pandemic in January 2020, about 768 million people globally have been infected by COVID-19. While COVID affects the respiratory system, past studies show that it can also lead to issues in other parts of the body, including the cardiovascular system. A new study has found that people who have had COVID have stiffer arteries compared to people who never had this viral infection. Scientists believe this arterial stiffening may cause early vascular aging of as much as five years.

Does semaglutide really contribute to vision loss?
2025-08-21

Does semaglutide really contribute to vision loss?

As the popularity of GLP-1 medications used for weight loss continues to increase, more research is being done to further examine potential side effects of these medications. One such side effect is possible eye issues and vision loss, for which there is currently a great deal of conflicting information. Some studies link GLP-1 use to an increased risk for ocular diseases such as nonarteritic anterior ischemic optic neuropathy (NAION), diabetic retinopathy, papillitis, and optic nerve disorders. A new study reports that using semaglutide is not associated with an increased risk for eye disorders or diabetic retinopathy. While this new study found a connection between semaglutide use and NAION, researchers say that the current evidence is insufficient to establish a definitive connection between the two.

The secret to weight loss? Opt for minimally processed foods

People whose diet contained fewer processed foods lost more weight than people who ate more ultra-processed foods, a recent study confirmed. While both groups lost weight, those eating less in the way of processed foods shed twice as many pounds. The key to weight loss in both groups was likely that they both consumed a well-balanced diet, with the only difference being the amount of ultraprocessed foods they consumed.

Small change to how you walk may help relieve osteoarthritis pain

Osteoarthritis is a chronic, degenerative condition of the joints that most commonly occurs in people over the age of 40. The condition can affect any joint in the body, but is most common in the knees, hands and hips. Although there is no cure, the condition can be managed by staying physically active, maintaining a healthy weight, and taking medications to relieve pain. Now, a study has found that modifying your walking style may relieve the pain and slow the progression of knee osteoarthritis as effectively as commonly used medications.

Popular artificial sweetener may negatively affect cancer immunotherapy

Non-sugar, or artificial, sweeteners are widely used to reduce the energy in sweetened foods and drinks, particularly those marketed as diet, or low or no sugar. However, concerns about their possible health effects include links to gastrointestinal problems, metabolic effects, and even increased cancer risk. Now, a study has found that one of the most widely used artificial sweeteners, sucralose, could adversely affect cancer immunotherapy. The researchers suggest that by changing the gut microbiome, sucralose decreases the effectiveness of immunotherapy for several cancers.

Study finds turning point when body starts aging rapidly

Past studies show that human aging doesn’t necessarily happen at the same pace throughout our life. There is still much to discover about the aging process, especially when it comes to how it impacts the body’s organs. A new study found that by focusing on aging-related protein changes in the body, there is an acceleration in aging of organs and tissues around the age of 50. And of these proteins, scientists found that expressions of 48 of them linked to diseases increased with age, such as cardiovascular and liver disease.

Are 7,000 steps a day enough to see health benefits?

A lot of people focus on getting 10,000 steps a day for its purported health benefits. A new study says that walking for only 7,000 steps a day can help reduce a person’s risk for heart disease, type 2 diabetes, dementia, cancer, depression, and all-cause mortality. Scientists also discovered that walking around 4,000 steps a day still offers more health benefits than people with very low activity and about 2,000 steps a day.

High amounts of ultra-processed foods may increase lung cancer risk by 41%

As the proportion of ultra-processed foods (UPFs) in the Western diet increases, concerns are growing about their health effects. Studies have linked UPFs with many health conditions, including obesity, type 2 diabetes, cardiovascular disease, and several types of cancer. Now, a study suggests that high consumption of UPFs could increase a person’s chance of developing lung cancer. While observing a link, the study cannot prove that UPFs cause lung cancer, but highlights a need for further studies.

Why are colorectal, other GI cancers on the rise in younger people?

Increasing age is the greatest risk factor for all types of cancer, with most cases being diagnosed in people over the age of 60. However, in people under 50, there has been a rapid, worldwide increase in cancers of the digestive system, or gastrointestinal cancers. Although still far less common than in older people, early-onset colorectal cancer is now the leading cause of cancer-related deaths in men, and the second in women, in the United States. The exact cause is unknown, but the authors of a new review published in the British Journal of Surgery suggest that obesity, a Western-style diet, nonalcoholic fatty liver disease, smoking, excessive alcohol use, and even exposure to microplastics, may all be contributing to the rise. Another study, published in Nature Medicine, has further estimated that, without early intervention, as many as 15.6 million gastric cancer cases may occur in the next few decades, most of which, are attributable to infection with a common bacterium, Helicobacter pylori.
