Intermittent fasting, also known as intermittent energy restriction, is any of various meal timing schedules that cycle between voluntary fasting (or reduced calorie intake) and non-fasting over a given period. Methods of intermittent fasting include alternate-day fasting, periodic fasting, and daily time-restricted feeding.Intermittent fasting may have similar effects to a calorie-restriction diet, and has been studied in the 21st century as a practice to possibly reduce the risk of diet-related diseases, such as metabolic syndrome.
The American Heart Association stated in 2017 that intermittent fasting may produce weight loss, reduce insulin resistance, and lower the risk of cardiometabolic diseases, although its long-term sustainability is unknown.
A 2019 review concluded that intermittent fasting may help with obesity, insulin resistance, dyslipidemia, hypertension, and inflammation.Adverse effects of intermittent fasting have not been comprehensively studied, leading some academics to point out its risk as a dietary fad. The US National Institute on Aging stated in 2018 that there is insufficient evidence to recommend intermittent fasting, and encourages speaking to one's healthcare provider about the benefits and risks before making any significant changes to one's eating pattern.Fasting exists in various religious practices, including Buddhism, Christianity, Hinduism, Islam, Jainism, and Judaism.

    URGENT Intermittent clunking noise in or near water softener

    Noise seems to stop when softener is bypassed, not 100% certain. Noise is intermittent, a thwack/thump we can feel in the inlet pipe. It's only for a few hours a day, and never when water is running. Harvey's water softener is 4 years old and water is from mains, not a tank. Salt is not blocked...

    WB combi has recently had it's annual service. It has been working reliably up to that point for many years. Now we keep losing hot water - temps on boiler increase over 100 on the display and it shuts down heat. Engineer claims it's coincidental and must be a blocked heat exchanger that has...

    Ideal Logic +18, intermittent fault

    Have an Ideal Logic + 18 with intermittent fault. When on demand the display constantly changes from O to C but burner doesn’t start. Can fix by switching Off then On again, but this only lasts for a day or two. As it’s an intermittent fault I’m reluctant to call out an Engineer. Any ideas?

    What can cause intermittent flow on hot tap?

    Can anyone advise? The problem is on a hot tap (not as the cold tap as shown) - the water intermittently stops and then goes to a trickle - turning the tap on and off the water then starts again - the next day it goes back to a trickle. I don't think it can be an airlock - is there a mechanism...
