Many people want to eat more healthily but find it difficult to change their diet. So what happened when Michael Mosley altered not what he ate, but when he ate?
We’ve known for some time that altering the time at which you eat can affect your weight and metabolism. At least if you are a mouse.
Based on mice studies, it seems the secret to improving your health is to restrict the time window within which you eat, and by doing so extend the amount of time you go without food.
A few years ago Prof Satchidananda Panda, from the world-famous Salk Institute in California, showed that mice fed on a high-fat diet, but only allowed to eat within an eight-hour window, were healthier and slimmer than mice that were given exactly the same food but allowed to eat it whenever they wanted.
In a more recent study the same researchers again subjected hundreds of mice to different lengths of daily fasts, ranging from 12 to 15 hours.
