It’s not WHAT you eat, but WHEN you eat…

Wouldn’t it be great to shed some kgs without cutting out our favourite meals?


There are studies that show that this is possible.  It all started with tests on mice where scientists discovered that moving their meals closer together during the day and lengthening fasting periods overnight caused a drop in sugar and cholesterol levels, making them healthier and leading to weight loss.  In this study the mice under test ate exactly the same meals as the control mice (see study abstract below).

Following this, a study was conducted by the University of Surrey to test the same principle on 16 human volunteers, as shown in the BBC TV programme, ‘Trust Me, I’m a Doctor’.  All of the volunteers initially had their blood fat, blood sugar and body fat measured following 12 hours of fasting.  The volunteers were then separated into two groups and the test conducted over 10 weeks.  The first group was the control group and could eat as per their normal routine.  The second group was asked to shift their breakfast to be 90 minutes later and their dinner to be 90 minutes earlier and to exclude all drinks and snacks after their evening meal.  As a result of these changes the second group had 3 more hours of fasting per night.  All of the participants had to keep a food diary to make sure that they had been eating similar amounts of food as normal.

At the end of the 10 week period both groups repeated the measurements that were taken at the start of the test.

The study demonstrated significant changes that were very similar to the tests on mice.  The group that had the longer fasting period showed a change in their levels of blood sugar and cholesterol, but no change in blood fat.  This group was shown to have lost body fat as a result of the experiment.


Consequently, this study has confirmed that the time that we eat DOES matter.  Eating late dinners is likely to result in weight gain and longer periods of fasting will improve the chances of losing some kgs.  Combining this knowledge with exercise and a healthy diet could produce incredible results.
