The study also found that this type of exercise may be more effective than continuous moderate-intensity exercise.
A study found that obese patients with 'metabolically healthy obesity' had less deterioration in heart structure and function, leading to better survival rates. Metabolically healthy obese patients also had the best chance of survival compared to those with metabolic risk factors.
A new study found that underweight and morbidly obese individuals are at an elevated risk of hospitalization with influenza-like illness. The risk follows a 'U' shaped curve, indicating those at both extremes have a higher likelihood of developing severe symptoms.
A new study found that left gastric artery embolization, a weight loss procedure, not only reduces body fat but also leads to significant muscle mass loss. The researchers emphasized the need for proper nutritional counseling after the procedure to mitigate this risk.
A new study suggests that a molecule called BMP8b could be used as a drug to increase the amount of brown fat in humans and make it more active. In mice, increasing BMP8b levels changed some white fat into brown fat, leading to increased energy burn and lower risk of heart attack. Further research is needed to confirm its effectiveness.
Scientists have discovered that specific molecules produced by intestinal bacteria are altered during three instances associated with human obesity. The study also found that the gut microbiome undergoes fluctuations in a 24-hour rhythm and influences circadian biology, predisposing individuals to obesity and glucose intolerance.
A study of over 110,000 respondents found that morbid obesity was strongly associated with chronic obstructive pulmonary disease (COPD) in never-smokers. In particular, among older women, those with morbid obesity had a higher prevalence of COPD compared to their normal-weight peers.
A study of over 143,000 female nurses found that rotating night shift work and an unhealthy lifestyle significantly increase the risk of type 2 diabetes. The risk is higher than the sum of individual factors, suggesting an interaction between the two.
Researchers at Ohio University are exploring a protein that naturally occurs in the body to prevent obesity and type 2 diabetes. The protein, Apolipoprotein A-IV, is known to act as a satiation protein, telling the body to stop eating.
A study found that employee-focused health promotion programs can lead to increased weight stigma, discrimination, and decreased wellbeing among employees with obesity. In contrast, employer-focused programs may be more effective in promoting healthy behavior.
Researchers found a bright appearance on deltoid muscle ultrasounds is associated with type 2 diabetes, indicating earlier treatment may be warranted. The study suggests using shoulder ultrasound as a supplemental screening option to detect undiagnosed patients.
