Mini-Artikkel: Hvorfor går man så lett opp i vekt igjen etter en diett?

 De fleste av oss klarer fint å gå ned i vekt over en kort periode, men problemet er i mye større grad at man ikke klarer å opprettholde dette vekttapet. James Krieger* har her en forklaring på hvorfor dette skjer, samt to gode tips for å motvirke det:

«One of the reasons you burn less calories when you lose weight is because you

become more efficient performing your activities of daily living.  In other words, you burn less calories for the exact same movement, and this decrease in calorie burn is greater than you would expect based on the weight loss alone.  This increase in efficiency is accompanied by 

changes in enzyme activity in your muscles, as your muscles try to get more “bang for the buck”.  In essence, your body is trying to conserve energy, which makes it very easy to regain weight.

There are two ways to counteract this. The first is a deliberate and conscious effort to dramatically increase your overall movement and NEAT** levels during the day…. The other way is to engage in more high intensity exercise (particularly interval training), as the efficiency effect disappears at higher exercise intensities.  Certainly, our bodies don’t help us when it comes to maintaining long term weight loss, but by taking these steps, we can help make the process easier.»

** NEAT: Non-exercise activity thermogenesis» – Aktivitet utenom trening, som gåturer, spontane bevegelser i hverdagen osv.
