Carbohydrate availability describes whether dietary carbohydrate and the body's carbohydrate stores—especially liver and muscle glycogen—are sufficient for the demands of exercise, recovery, and daily metabolism. It is not the same as energy availability, which describes the dietary energy remaining after exercise relative to fat-free mass. A person can consume enough total calories yet still have low carbohydrate availability if carbohydrate is replaced largely by fat. Why carbohydrate availability matters Carbohydrate supplies blood glucose and replenishes glycogen, the stored carbohydrate t... exercise diet metabolism muscle bone carbohydrates
Read more[toc position='left'] Exercise snacks are brief, deliberately planned bouts of vigorous physical activity distributed throughout the day. A snack may be a fast stair climb, bike sprint, set of air squats, or short bodyweight circuit lasting roughly 20 seconds to a few minutes. The defining features are that the effort is intentional, short, and separated from the next bout by a longer period of ordinary daily activity. This approach lowers two common barriers to exercise—time and access to facilities—and can improve cardiorespiratory fitness and glucose regulation. It also provides a practical... exercise cardiovascular cognition exercise snacks
Read more[toc position='left'] Introduction Light does much more than help us see. It tells the brain what time it is. That signal coordinates sleep and wakefulness, hormone release, metabolism, mood, and hundreds of other processes that follow a roughly 24-hour rhythm. Its effects depend not simply on how much light reaches the eye, but when it arrives. Bright light in the morning and throughout the day strengthens the body's daytime signal. Dim evenings and dark nights allow the biological night to unfold. Modern life often reverses that pattern, giving us biologically dim days and unusually bright n... metabolism sleep depression mental health melatonin eyes circadian rhythm
Read more[toc position='right'] When we engage in high-intensity exercise, our muscles become mini biochemical laboratories (https://www.youtube.com/watch?v=YXl1evV_spo), synthesizing compounds like lactate and myokines that circulate throughout the body and travel to our organs, where they exert a variety of signaling effects, including the synthesis of brain-derived neurotrophic factor (BDNF) (https://bdnfprotocols.com/)in the brain. Some of these molecules have anti-cancer properties. Vigorous exercise is also the most potent way to increase your VO2 max, also known as cardiorespiratory fitness, wh... exercise brain bdnf aerobic cardiovascular mortality aging exercise snacks

Watch now[toc position='left'] Senescence is a response to stress in which damaged cells terminate normal growth cycles to prevent dysfunctional cells from reproducing. Senescence is a vital cellular process involved in embryonic development, wound healing, and cancer immunity; [ref doi='10.1242/dev.151837'] however, the accumulation of senescent cells is associated with diseases of aging such as cancer, cardiovascular disease, type 2 diabetes, Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, sarcopenia, and glaucoma.[ref doi='10.1016/j.cell.2017.05.015'] [ref doi='10.3390/ijms19102937'] ... neurodegeneration senescence aging

It is a member of the genus Lactobacillus, which comprises most of the bacteria that live on and in the human body. Lactic acid-producing bacteria, such as those in the Lactobacillus genus, are commonly used in probiotic supplements.[ref doi='10.1016/j.tim.2021.01.003'] Furthermore, some online resources provide step-by-step instructions for at-home bulk production of yogurt with L. reuteri enrichment.

Common examples of aerobic exercises are walking, running, swimming, dancing, and other activities that increase heart rate and breathing. Exercise elicits a wide range of physiological changes in the body that improve cardiovascular, neurological, and metabolic health.

While the consumption of SSBs has declined in recent decades, they remain a leading contributor to sugar intake among people living in the United States. While the over-consumption of sugar from any source is harmful for health, SSBs present a physiologically unique risk to health due to a converging set of factors.
