We all know that eating clean and exercising are the dynamic duo for a healthy life and weight management.

But how much exercise is too much?

Australian nutritionist and best-selling author, Jessica Sepel, suggests too much exercise is doing far more harm for our bodies than good.

The health guru shared her views and tips in a new video on her blog.

Best-selling author Jessica Sepel claims too much exercise is harmful for weight management

Jessica said less intense exercise, but more restorative training, is the best plan

In the video, Jess explained when she was a practicing nutritionist, she would see many women who would exercise twice a day but still couldn't shift their weight.

'I was a former fad dieter and normally when you're a dieter, you're also an over-exerciser,' Jess said.

By giving up lots of intense exercise, such as spinning, running and boot-camp, Jess said she regained her energy and felt refreshed in the morning, rather than tired from exercising.

'When I would tell my clients to pull back on their exercise, they would look at me with terror in their eyes,' she said,

'I would tell them to reduce their intense exercise such as running for more restorative exercises such as yoga, Pilates and a brisk walk.'

According to the nutritionist, when you work out too much 'your cortisol levels spike'.

'Remember, your body doesn’t know the difference between exercise stress and normal stress,' she said.

'When you stress out about working out, your cortisol levels go crazy. And high cortisol means your body can’t burn off fat – it’s too busy trying to balance out your parasympathetic and sympathetic nervous systems.'

The results of cutting back on intense exercise were obvious, according to Jess and her clients.

'They would come back into my office and their clothes were looser, their energy levels were higher, and they were sleeping much better.

Jess encouraged her followers to take it easy, both with the exercise and on themselves.

'I encourage you to let go of the guilt you're feeling around exercise, and not put the pressure on yourself to be exercising every day, perfectly and intensely.

According to Jess and expert studies, 30 minutes of exercise a day is a healthy and manageable way for weight balance.

'Maybe two session of interval and high intensity training per week and lots of yoga, Pilates and walking seems to be what works,' she suggests.
