It's not the couch, after all

Exercise, schmexercise.

We have good news and bad news, couch potatoes.

First, the good news.

It's not what you do.

It's what you eat.

Now the bad news.

It's the same as the good news.

Exercise 'not key to obesity fight'

Dr Malhotra said: "An obese person does not need to do one iota of exercise to lose weight, they just need to eat less.

"My biggest concern is that the messaging that is coming to the public suggests you can eat what you like as long as you exercise.

"That is unscientific and wrong. You cannot outrun a bad diet."

But it's not just about total calories.

But despite this public health messaging had "unhelpfully" focused on maintaining a healthy weight through calorie counting when it was the source of calories that mattered most - research has shown that diabetes increases 11-fold for every 150 additional sugar calories consumed compared to fat calories.

The article confirms that exercise is important for lots of reasons, as is proper regard for what you eat.

But not for obesity control or weight loss.
