Clinical data indicates that a high body mass index (BMI) in multiple myeloma patients is associated with more aggressive disease biology and poorer treatment outcomes. This is an independent risk factor, separate from common comorbidities like diabetes or hypertension.

Focusing on building muscle is crucial for long-term health, particularly for women entering perimenopause. Muscle helps regulate blood sugar, reduces inflammation, and protects against osteoporosis, dementia, and heart disease, making it a vital health indicator.

Despite low individual recurrence rates, the vast number of women diagnosed with early-stage breast cancer means they account for most deaths. The annual proportion of deaths from stage 2 disease rose from 26% to 40%, while stage 1 accounts for another 23%. This highlights the need for better monitoring, like ctDNA, in this population.

Wave Life Sciences' stock was halved after its obesity drug failed to show significant overall body weight loss. Investors overlooked the clinically important reduction in visceral fat, which is more strongly linked to poor health outcomes. This highlights a market misunderstanding of key clinical endpoints.

Focusing on overall body fat percentage is an outdated approach. A more valuable future biomarker for health will be muscle quality, specifically the amount of fat that infiltrates muscle tissue. This fat is a better indicator of metabolic health and may store environmental toxins.

You don't have to be overweight to have dangerous levels of visceral fat surrounding your organs. These individuals, often called "metabolically unhealthy lean," appear healthy but have biomarkers similar to obese people, posing significant health risks they are unaware of.

Patients often worry that anti-estrogen therapies directly cause weight gain. However, the mechanism is more nuanced: the drugs induce a postmenopausal state characterized by inflammation and metabolic dysfunction, which, combined with natural aging, makes weight gain more likely and weight loss more difficult.

Contrary to popular belief, research shows that individuals with a higher Body Mass Index (BMI) often live longer than those with 'normal' or low BMI. Higher body weight can be protective against conditions like osteoporosis and cancer and can aid faster recovery from heart surgery.

Standard BMI categories fail to capture the elevated diabetes risk in certain ethnic groups. Clinicians must recognize that patients of South Asian, Korean, or Chinese descent are at higher risk for hyperglycemia at a much lower BMI (e.g., a BMI of 23 should be considered overweight).
