How to explain fasting in animal?
Best insight from top research papers
Fasting in animals is a complex physiological process involving behavioral, physiological, and biochemical responses to maintain homeostasis while relying on endogenous resources. It leads to metabolic rate reduction, tissue maintenance, and a shift towards lipid utilization for energy. Fasting affects hormone regulation, immune capacity, and gut microbiota dynamics. Studies on mice fasting show changes in hormone balance, body weight, metabolism, and cardiovascular parameters. In rats, fasting impacts bone quality by decreasing bone density and strength temporarily. Wild vertebrates undergoing fasting exhibit minimal oxidative stress, suggesting fasting promotes redox balance. Fasting in fish leads to changes in digestive organ size and energy storage, affecting body condition and isotopic composition. Overall, fasting in animals involves intricate adaptations to survive periods of limited food availability.

What does fasting cure mean?5 answers"Fasting cure" refers to a deliberate period of fasting with limited food intake, often accompanied by medical supervision. It has been traditionally practiced for various reasons, including cultural, religious, and therapeutic purposes. Studies have shown that medically supervised fasting can be efficacious in treating important health conditions such as rheumatic diseases, chronic pain, hypertension, and metabolic syndrome. In Ayurveda, fasting is considered a means of purification and aiding in spiritual life, as it helps in digestion of metabolic toxins, activates tissue metabolism, and removes blockages in the body’s channels. Additionally, fasting has it has been observed that fasting can have positive effects on both the body and the mind, leading to improvements in various diseases and overall health. The practice of fasting has been found to be effective in treating patients poisoned by contaminants, with significant improvements in symptoms and symptoms.
How does fasting influence body weight?5 answersFasting has a significant impact on body weight by promoting weight loss and influencing various metabolic parameters. Studies have shown that fasting leads to a reduction in body weight, body mass index (BMI), fat mass, and waist circumference in individuals with overweight or obesity. Additionally, fasting decreases body weight, lean body mass, and fat content in both trained and untrained individuals, indicating its effectiveness in weight management. Furthermore, fasting can reduce body mass and release mercury from tissues, highlighting its role in weight loss and potential detoxification effects. Overall, fasting is associated with positive changes in body weight and composition, making it a valuable approach for individuals aiming to manage their weight effectively.
Significance of fasting in Ramadan?5 answersFasting during Ramadan has several significant effects on human health. It has been found to promote weight loss in obese patients and lower levels of LDL-C and triglycerides. Additionally, Ramadan fasting has been shown to improve the gut microbiome, modify gut hormone levels, and reduce proinflammatory markers. Fasting also has positive effects on mental health, including alleviating symptoms of depression, anxiety, and psychosis. In terms of oral health, it is important to maintain good oral hygiene practices during Ramadan to prevent dental decay and erosion. Furthermore, studies have shown that Ramadan intermittent fasting (RIF) can lead to improvements in anthropometric and metabolic indices, gastrointestinal symptoms, and motility. RIF is associated with lower calorie intake, decreased body weight and fat mass, and improved lipid profiles. Overall, fasting during Ramadan has various beneficial effects on physical and mental health, as well as oral health and metabolic markers.
What effect does fasting have?5 answersFasting has various effects on the human body. It leads to the breakdown of liver glycogen and muscle protein to produce glucose for the brain, as well as the gradual depletion of fat stores, resulting in the release of glycerol and fatty acids into the bloodstream and the production of ketone bodies in the liver. Fasting also has a significant influence on the immune system function, suppressing inflammatory biomarkers and reducing oxidative and inflammatory stress markers. In terms of cardiovascular activities, long-term fasting in a confined environment alters the autonomic regulation to the heart rate and induces changes in serum sodium, serum calcium, QTc intervals, and systolic blood pressures. Additionally, fasting has been shown to impact the gut microbiota, reducing inflammation, improving insulin signaling and blood glucose control, and potentially affecting various diseases. Prolonged fasting has been found to increase vitamin D levels, vitality, and quality of life compared to a normal diet.
Cancer and benefits of fasting5 answersFasting has been shown to have potential benefits in cancer treatment. It can limit cancer cells' adaptability, survival, and growth, and increase the effectiveness of cancer treatments while reducing side effects. Fasting and fasting mimicking diets (FMDs) can induce stress-resistant modes in normal cells, protecting them from cancer therapies, while increasing the toxicity of therapies in cancer cells. Fasting or FMDs can also improve the effects of chemotherapy, hormone therapy, radiotherapy, and immunotherapy, and reduce treatment-emergent adverse events. Fasting can induce an anti-warburg response in cancer cells, forcing them to improve in oxidative phosphorylation and leading to cell death. Research on fasting shows its role in reducing oxidative damage, inflammation, and boosting cellular protection, which may have positive health effects in relation to cancer risk.
How does fasting benefit the body?5 answersFasting has been found to have several benefits for the body. It can reduce inflammatory markers, oxidative stress, body weight, abdominal circumference, fasting blood glucose, LDL cholesterol, triglyceride levels, and blood pressure in healthy individuals. In people at risk or with cardiovascular disease, fasting can also reduce body weight, body mass index, abdominal circumference, fat percentage, blood pressure, triglyceride levels, and biomarkers of inflammation, oxidative stress, and endothelial dysfunction, while increasing vascular endothelial growth factor. Islamic fasting specifically has been associated with a reduced risk of diabetes, cardiovascular diseases, hypertension, and cancer, while also positively influencing body weight, lipid and glucose levels, and renal and immune function. Fasting has also shown potential as a method for weight loss and improving cardiometabolic health, with different fasting patterns such as alternate-day fasting, intermittent fasting, time-restricted eating, and periodic fasting showing beneficial effects. Overall, fasting has been found to have positive effects on human health, including metabolic health, chronic disease prevention, and cellular response to stress.
