![]() However, some aspects of mouse physiology can be different to humans. Most of what we know today about intermittent fasting and time-restricted eating is from mouse studies, which demonstrate remarkable weight loss and overall health benefits associated with these types of dietary interventions. This means eating all our calories in a consistent 8-12 hour, or even shorter, interval each day. There are several types of intermittent fasting, one of which is time-restricted eating. Intermittent fasting is one way to restrict the timing, rather than the content, of what we eat. Nutritional interventions are increasingly focused not only on “what” we eat but also “when”. Shift-workers, for example, and people who work evening, night or rotating shifts, have a higher risk of obesity, heart disease and diabetes.īut adopting an eating pattern that aligns with our circadian rhythm can reduce these risks. Erratic eating patterns, including late-night meals, have been linked to weight gain and a greater risk of metabolic disease. Working against this default stage, by regularly eating when we’re supposed to sleep and fast, can compromise these processes and impact our health. Eating when we're supposed to be sleeping can impact our health. Food digestion, nutrient uptake and energy metabolism is optimised to occur when we’re supposed to be active and eating. Our body is biologically prepared to have food during the day. It can also tell us the best time to eat. It tells us to be awake and active during the day, and rest and sleep during the night. Our internal biological timekeeper, or circadian clock, regulates many aspects of our physiology and behaviour. So what does this mean for meal scheduling? And can intermittent fasting help? Our body clock controls more than our sleep However, research increasingly shows our health is not only affected by what and how much we eat, but also when we eat. Frequent snacking is also common, over a window of around 15 hours. ![]() ![]() It’s now common to have four or more meals a day, with the most calories consumed later in the day. Today, with access to an abundance of food, we rarely experience prolonged periods of fasting, except for weight loss or religious practices. Over time, the development of modern agriculture and the transition to industrialised societies changed our regular eating patterns, shifting our dinner time to later in the day to accommodate work schedules. Their access to food relied on successful hunting, fishing, and the availability of wild plants. Can intermittent fasting improve my health? Here’s what the science says.Įarly hunter-gatherers faced long periods of fasting. ![]()
