Summary
Modern lifestyles disrupt biological rhythms, impacting metabolism. Time-restricted feeding shows promise for improving metabolic health and managing obesity by synchronizing circadian clocks.
Area of Science:
- Chronobiology
- Metabolic Health
- Nutrient Sensing
Background:
- Modern lifestyles disrupt biological rhythms and circadian clocks.
- Circadian rhythms regulate numerous physiological functions, including metabolism.
- Peripheral clock synchronization via feeding/fasting cycles is crucial for metabolic processes.
Purpose of the Study:
- Emphasize nutrient sensing by peripheral clocks.
- Highlight central and peripheral clock communication in metabolic regulation.
- Discuss the impact of altered eating behaviors on metabolism.
Main Methods:
- Review of scientific literature on circadian rhythms and metabolism.
- Emphasis on nutrient sensing mechanisms.
- Analysis of clock communication pathways.
Main Results:
- Peripheral clocks are sensitive to nutrient availability.
- Clock communication is vital for energy homeostasis.
- Disrupted eating patterns contribute to metabolic diseases like obesity and type 2 diabetes.
Conclusions:
- Proper synchronization of circadian clocks is essential for metabolic health.
- Time-restricted feeding may help mitigate metabolic dysfunction.
- Understanding clock mechanisms offers therapeutic potential for metabolic disorders.

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...

671
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

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...

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.

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...
