Intermittent fasting (IF), widely recognised in Blackburn and around the world, has achieved remarkable traction within the health and wellness sector due to its potential to enhance numerous facets of human health. Although recent deliberations have raised possible issues concerning IF and cardiac health, broaching this subject necessitates a balanced standpoint. It’s crucial to appreciate the necessity for continued research while acknowledging the significant evidence backing IF’s benefits. This article offers a holistic understanding of the favourable effects of intermittent fasting, endorsed by credible research studies and publications.
Is weight loss possible through intermittent fasting?
Intermittent fasting’s influence on metabolic health is one of its most established benefits. Research has shown that IF can spark positive changes in weight control, insulin sensitivity, and cardiovascular risk factors.
Weight control and obesity: According to a thorough 2024 review of 23 meta-analyses, adults grappling with overweight or obesity issues can use IF to considerably reduce waist circumference and fat mass. The lifestyle also boosts key biochemical indicators such as fasting insulin, low-density lipoprotein cholesterol, total cholesterol, and triacylglycerols (1). Other research papers highlight that intermittent fasting can promote weight loss, fat mass reduction,and better body composition(2-4).
Insulin sensitivity: A 2018 study featured in Cell Metabolism showed how IF enhances insulin sensitivity, which isn’t contingent on weight loss (5). Another study showcased IF’s ability to improve the body’s glucose metabolism post-meals beyond what calorie restriction can achieve (6). Enhanced insulin sensitivity is essential in warding off type 2 diabetes and fortifying overall metabolic health.
Cardiovascular health: IF can help lower blood pressure, cholesterol levels, and inflammatory markers, all of which contribute towards heart health (7).
Does intermittent fasting influence mental health?
Apart from its metabolic benefits, there have been connections observed between intermittent fasting and enhanced brain health and psychological wellness.
Neuroprotection: A review article published in The New England Journal of Medicine (2019) gathered research, indicating that IF might improve brain health and delay neurodegenerative diseases. This could be due to increased stress resistance and reduced inflammation (8).
Mood enhancement: According to a study in The Journal of Nutrition, Health and Aging (2013), IF could uplift mood, potentially influenced by changes in brain chemistry and hormonal balance (9).
Does intermittent fasting extend life expectancy?
Growing evidence uncovers IF’s potential role in promoting longevity and enhancing cellular health, mainly via mechanisms like autophagy, which involves the removal and recycling of damaged cell components.
Autophagy and longevity: A 2024 study in Nature Communications established that a diet mimicking fasting triggers biological adaptations, aligning with a decrease in biological ageing (10). Moreover, IF encourages autophagy in the liver, fat, brain, and muscle, correlated with a longer lifespan and a reduction in age-related and chronic metabolic conditions (11).
Conclusion
While analysing IF’s research, it is essential to scrutinise its likely concerns alongside the vast evidence supporting its benefits for metabolism, cognitive function, and general well-being. As responses to any health intervention are individualistic, it is advisable for people, particularly those in Blackburn, to reach out to health professionals before initiating a new dietary program or intermittent fasting plan. As research progresses, further insights into the elaborate relationship between intermittent fasting, health, and disease, will inform recommendations based on up-to-date scientific proof.
