“Inflammation and elevated levels of the hormones insulin and estrogen can lead to an increased risk of breast cancer. Meal timing can impact these risk parameters. The thinking is that humans have evolved to eat during the day, when the body is more insulin sensitive, and to fast at night.”

“They distinguish circulating 25-hydroxyvitamin D from the active hormone 1,25-dihydroxyvitamin D and explain why sun exposure also carries activity, nitric-oxide, and lifestyle signals that complicate observational comparisons.”

“Dr. Patrick explains the conversion pathway: vitamin D3 becomes 25-hydroxyvitamin D in the liver, the main circulating blood measure, and then 1,25-dihydroxyvitamin D in the kidney. The active steroid hormone binds the vitamin D receptor and regulates gene transcription.”

“Time-restricted eating can help some people reduce eating opportunities, but controlled trials have not found a consistent visceral-fat advantage over matched dietary counseling or calorie restriction.”

“In this clip from Dr. Rhonda Patrick's appearance on Modern Wisdom, she explains how added sugar can affect hormones as well as appetite. The study she cites did not test a dessert, sugary drink, or habitual added-sugar intake: 74 men completed a standard 75-gram oral glucose tolerance test, after which mean testosterone fell about 25% and remained below baseline at two hours.”

“In this clip from Dr. Rhonda Patrick's presentation for Biote, she explains how cold can sharply increase norepinephrine, a hormone and neurotransmitter involved in vascular control and alertness.”

“Circadian rhythms modulate a wide array of physiological processes, including the body’s production of hormones that regulate sleep, hunger, metabolism, and others, ultimately influencing body weight, performance, and susceptibility to disease.”

“Insulin-like growth factor-1, or IGF-1, is a hormone that plays key roles in growth and neurogenesis but has also been implicated in aging and stimulating the growth of cancer. Therefore, it may be desirable to achieve higher IGF-1 levels in the brain, while maintaining lower levels in the rest of the body.”

“Vitamin D3 is converted into calcitriol, a steroid hormone that binds the vitamin D receptor and changes gene expression. In this clip from Dr. Rhonda Patrick's presentation at the Vibrant Wellness Longevity Summit, she explains how limited UVB exposure, skin pigmentation, age, and higher body fat can make low vitamin D status more likely.”

“These habits reduce avoidable exposure opportunities, while persistent symptoms or reproductive concerns call for standard clinical testing and evaluation before considering hormone treatment. This clip is excerpted, with permission, from Dr. Rhonda Patrick's appearance on Triggernometry.”
