Gym junkies are fighting a losing battle against obesity, say scientists.
Aussie researchers have blamed the world’s obesity epidemic on people eating more and not on people exercising less.
Obesity epidemic could have been avoided if people simply ate less.
Changes in physical activity played a minimal role.
Scientists found evidence to suggest people were actually exercising more now.
Food intake still explains the weight gain, but there may have been increases in physical activity over 30 years that have blunted what would otherwise have been a higher weight gain.

A gym has replaced its dumbbells with human weights to encourage people to exercise. Members of Gymbox, London, can choose one of five people to lift, ranging from two short people to a 155kg man.
The gym already runs a “chav fighting” self-confidence class and “WAG workouts” to make women more attractive to footballers.
The human weights, who sit on adapted machines, help gym-goers by letting them visualize what they are lifting.
Gymbox owner said human weight lifting was the “ultimate embodiment of visualization theory.
Creating a mental image or intention of what you want to happen or feel is proven to improve physical and psychological performance.
Gym-goers want to improve not only their bodies but also their minds, according to a new book.
Harvard Medical School psychiatrist and author of Spark!John Ratey, says exercise is the single most powerful tool to optimize brain function.
Ratey also says an hour of moderate exercise, such as power walking or jogging, four days a week, a 45 minute burst of intense activity, such as squash or running, twice a week, combined with strength training and balance drills maximizes brain power.

Christmas festivities can have repercussions that last a lot longer than one merry day.
A few extra calories quickly turn into a few kilos and before you know it half a year of good work can be undone.
We tend to have too much Christmas puddling and that’s washed down with a few drinks too many, we get on the scales after those big sessions and we’re well over that we were before. In fact, it’s not just Christmas that’s to blame, but the entire summer holiday season.
But this doesn’t have to be the case, we should look at this time as being an opportunity to exercise. If children are home you can do something active with them, play a game, go for a walk, this benefits the fitness of the entire family.
Now is a good time to assess you fitness goals for the year. New Year’s resolutions could work but only if approached correctly.
Goals need to be realistic but challenging.
If we set the bar too low, then the benefits are going to be insignificant. If you set it too high and it becomes impossible to achieve, it’s going to be demonstralising.
If you say you want to walk 30 minutes a day three times a week for one month, that’s a behavior change.
If you say you want to walk 5km in 40 minutes by the end of the month then that’s an outcome.
