Is your alarm clock ruining your diet?

September 7, 2012, 8:10 amnewideanz

Do you wake up to the alarm on weekdays then sleep in on weekends? It may be doing you more harm than good – and even
causing weight gain!


German scientists have coined this sleep pattern ‘social jet lag’.

They say when we keep a different sleep schedule on weekdays to the weekends, our circadian rhythms are out of sync with our daily work routines, causing our bodies to fly back and forth between time zones every weekend – even though we’re not travelling anywhere!

What’s worse, they’ve found that adults with different weekday and weekend sleep schedules have triple the odds of being overweight – and the longer the gap between their weekday and weekend ‘time zones’, the higher their body mass index (BMI).

This research follows previous studies that found an increased risk of obesity among shift workers, along with chronic diseases such as diabetes, could be blamed on their irregular meal times. This in turn disrupts shift workers’ metabolisms.

These same factors may be at play with social jet lag, say researchers.

By eating when our body doesn’t want to eat, we may not be digesting our food properly and therefore may store more of it as fat if we hit the hay straight away.

So next time you ignore your alarm clock and have a leisurely lie-in on a Tuesday morning, you can tell your boss that it’s all part of your new weight-loss regimen!

    LOL @ rockanroll. They say it's best to have people think you are a fool than to open your mouth and remove all doubt. Not only the spelling error but the inability to grasp the key point that the story is trying to make, that it is people who need to get up early during the week and then sleep in at the weekend that are more at risk of being overweight. How does this apply to people on the dole? They can sleep in every day of the week.

    I agree completely patricia.It is mind blowing. Not just for their lack of spelling skills but also for the number of weak & pathetic comments that are made.

    Understanding each other with empathy is now considered more important than "spelling per se". We have up to 170 cultures in one country, and we can't expect everyone who is learning a new language to be word perfect. Empathy is about allowing others to express their point-of-view, and then being very curious at what experience/belief system has created that point of view. If you think you are an expert, then guess what, you stop learning. Einstein said that 99% of knowledge will be found to be not true when a bigger microscope is found to see more clearly.
