Summary
Resetting the body clock through feeding schedules can extend lifespan and improve health in mammals. This approach enhances metabolic and physiological synchrony, counteracting aging and disease.
Area of Science:
- Chronobiology
- Gerontology
- Metabolic Physiology
Background:
- Circadian clock disruption is linked to aging and disease.
- A well-functioning circadian system promotes well-being and longevity.
- Feeding regimens can influence circadian rhythms.
Purpose of the Study:
- To review recent findings on the link between circadian rhythms and aging.
- To explore how circadian rhythm manipulation affects lifespan extension.
- To understand the role of feeding in synchronizing metabolism and physiology.
Main Methods:
- Literature review of recent studies.
- Analysis of mammalian models.
- Focus on feeding regimens and circadian clock resetting.
Main Results:
- Circadian rhythm resetting is associated with increased longevity.
- Improved health and aging attenuation are observed with synchronized circadian rhythms.
- Specific feeding strategies can reset circadian rhythms effectively.
Conclusions:
- Manipulating circadian rhythms, particularly through diet, offers a promising avenue for extending lifespan.
- Synchronizing metabolic and physiological processes via circadian regulation is key to healthy aging.
- Further research into feeding regimens can unlock potential for healthspan and lifespan extension.

02:19Circadian Rhythms and Gene Regulation
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent years,...

02:45Biological Clocks and Seasonal Responses
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
01:26Aging
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:15Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
