Today James and I are a bit lost for words after reading a new study on how metabolism changes over a person’s lifetime. This study basically showed that people’s metabolism does not change drastically (or at all) between the ages of 20 and 60. This goes against everything we thought we knew about training and eating for people over 30. If this study holds true, we cannot use “slowing metabolism” or “middle-age spread” as an excuse for weight gain in middle-age. The focus will need to shift to making more significant lifestyle changes in order to see a change in your body.
Unfortunately, we don’t have the answers to many of the questions that came up from us – partly because the full details of the study have not yet been released. However, getting in some experts to comment and shed some light on this for us in the coming weeks on the podcast is a top priority. Watch (listen to) this space!
