A new study led by Harvard T.H. Chan School of Public Health found that low-carbohydrate diets rich in plant-based proteins and fats, along with healthy carbohydrates, are linked to slower long-term weight gain. Diets high in animal proteins and unhealthy carbohydrates, on the other hand, are associated with greater weight gain.
A study of 123,000 individuals found that low-carbohydrate diets emphasizing whole grains and plant-based foods are associated with slower weight gain in the long term. Low-carb diets relying on animal-sourced proteins and refined carbohydrates result in faster weight gain.

Research by Dr Janina Steinmetz found that people are more likely to see others as having good self-control if they blame a lack of money rather than time for abandoning New Year's resolutions. Studies involving around 1,200 participants showed that excusing financial constraints leads to better perceptions of self-control.
A new study suggests that US adults consume almost a quarter of their daily calories in snacks, often more than they do at breakfast, yet these snacks offer little nutritional value. Researchers analyzed data from over 20,000 people and found that snacks accounted for between 19.5% to 22.4% of total energy intake.

A new study found that social media platforms restrict user-generated content and advertising related to illegal muscle-building drugs but offer few restrictions on legal dietary supplements. This has raised concerns about the potential negative effects of these products on young people's health and behavior.
A study led by Brown University researchers found that mindfulness-based blood pressure reduction programs improve health behaviors associated with lower blood pressure. Participants in the program showed significant improvements in adherence to a heart-healthy diet and self-awareness, which influences dietary choices.

This novel dietary approach lowered hemoglobin A1c levels without calorie counting, offering potential for improved blood sugar management and overall health.
A new study published in JAMA Network Open found time-restricted eating to be safe and effective for people with Type 2 diabetes, helping them lose weight and control blood sugar levels. Participants who followed the time-restricted eating plan had an easier time sticking to it than those on a calorie-reduced diet.
A new study found that making simple substitutions like switching from beef to chicken or plant-based milk can reduce the average American's carbon footprint from food by 35%, while also boosting diet quality by between 4-10%. These small changes can have a significant impact on both climate and health outcomes.
A Baylor College of Medicine study analyzed metabolite data from over 4,000 adults and found no direct link between red meat consumption and markers of inflammation. The researchers suggest that body weight may be the driver of increased systemic inflammation instead.
The American Academy of Pediatrics reviews toddler 'formulas', finding they lack standard composition and nutrition requirements. The organization recommends a varied diet with fortified foods for toddlers, with no nutritional advantage over human milk or cow's milk.
A new study suggests that progressive strength training using resistance can protect against the detrimental effects of a high-protein diet. The research found that exercise protected mice from gaining excess fat mass, but did not affect blood sugar control. This paradoxical finding has implications for athletes and individuals with se...
A new study led by Richard Johnson, MD, suggests that fructose is the key driver of obesity, bringing together long-incompatible theories on dietary causes. Fructose lowers active energy in the body, triggering hunger and food intake, and fatty foods become the major source of calories driving weight gain.
The Kenyan government and food industry could save billions USD by implementing trans fat limits, which would also reduce heart disease cases and prevent deaths. Experts urge food manufacturers to prioritize consumer health by removing trans fats from products now.
Buck Institute researchers discover that advanced glycation end products (AGEs) in processed foods increase hunger and test willpower, contributing to overeating and obesity. By understanding the biochemical signaling pathway behind AGEs, scientists may develop strategies to limit their accumulation and promote healthy eating.
A new blood test has been developed to measure the levels of critical omega-3 fatty acids in the bloodstream, providing a convenient way to assess cardiovascular and cognitive health. The Omega-3 Index (O3I) is derived from two key fatty acids, EPA and DHA, which can be obtained only from certain dietary sources.
