Cardiorespiratory fitness may be a far greater predictor of gut microbiota diversity than either body fat percentage or general physical activity
“From the article: > Participants performed a graded exercise test to estimate peak cardiorespiratory fitness, assessments of total energy expenditure and examination of gut microbiota from faecal swipes. The results showed that participants with the higher cardiorespiratory fitness had significantly greater gut microbiota diversity compared to less fit participants. View full publication.”
Hallmarks of aging
“The assay can detect within-person changes in autophagic flux, but it remains a research method and is not a validated clinical biomarker of biological aging. Deregulated nutrient sensing The body employs many sensing pathways that detect intra- and extracellular fat, amino acid, and sugar concentrations.”
Polyphenol-Rich Diets and Brain Aging
“The main sources of added fat were olive oil and a handful of walnuts each day. Polyphenol-rich Mediterranean diet: The Mediterranean diet with the addition of 3–4 cups of green tea per day and a polyphenol-rich green shake at dinner.”
Exercise benefits men about to undergo cancer treatment.
“The first line of treatment for prostate cancer is commonly ADT, which involves the surgical or pharmaceutical suppression of serum testosterone levels. Side effects of ADT include body fat increases, muscle mass losses, and changes in cardiopulmonary and metabolic fitness.”
Vitamin D increases muscle strength and mass without altering body weight in mice.
“These findings suggest that vitamin D influences body composition and metabolism by preferentially allocating calories toward muscle development and overall growth rather than fat storage. They also highlight the intricate relationship between obesity and vitamin D status.”
Six 30-second cycling sprints triggered a broader and faster wave of blood signals than 90 minutes of moderate exercise.
“The response among metabolites followed a similar pattern: sprinting changed 203 immediately and 199 after three hours, while moderate exercise changed 31 and then 183. Plasma collected after sprinting changed the activity of 1,677 genes in fat cells, compared with 25 following moderate exercise.”
Sustained weight loss in women over 50 reduces breast cancer risk
“Body fat also alters hormone levels, which may increase the risk of developing hormone-sensitive cancers, such as breast cancer. In addition, body fat secretes a wide array of pro-inflammatory substances that damage DNA and inhibit apoptosis.”
Adenosine (part of ATP), also previously demonstrated anti-inflammatory and hair regrowth effects, now shown to brown fat -- making it energy using
