Proven benefits of SHED-IT

SHED-IT is easy to use and has delivered outstanding, sustained weight-loss results in rigorous randomised controlled trial testing, with men who use the program as recommended losing almost 10kgs throughout the 12 week program (4-5kg on average). These results are comparable with intensive weight loss programs that require multiple face-to-face sessions.

Additional proven health benefits

  • Reduced waist circumference, blood pressure, percent body fat and visceral fat area
  • Improved resting heart rate
  • Increased physical activity
  • Improved depressive symptoms and quality of life (physical and mental)
  • Reduced risky alcohol behavior
  • Improvements in erectile dysfunction
  • Reduced meal portion size

Sustained weight loss results

A recent study looked at the long term success of men who had lost weight using the SHED-IT Program. On average, the men lost 7.4 kg in the first 3 months. Three years later, the men had retained 60% of this weight loss, even though they received no additional support!

To put this in perspective, these results are significantly better than most scientifically evaluated weight loss programs (Dombrowski,, 2014) and comparable to intensive programs including a recent U.S. study, where participants received 20 face-to-face sessions during weight loss and 12 follow-up consultations after the program had finished (Svetkey, 2008).

What does the academic literature say about SHED-IT?

The unique approach of SHED-IT has been commended by international researchers as “A momentous step toward addressing the long overlooked need to develop behavioural weight control programs that appeal predominantly to men and have wide reaching potential to impact obesity among the male half of our population”

Davids Story: “Before SHED-IT I had tried nearly every kind of fad and fast-fix diet. They work at first, but as soon as you come off the diet, the weight piles back on. The SHED-IT program changed my whole approach to diet and exercise. The program has changed my life.”

“The structure of the program gave me simple insights and tools. Its simplicity is it's genius!"  57 years old (lost 8 kg)

“the most realistic weight loss program ever! I now have better control over when to stop eating and when to avoid foods that are kilojoule dense.”  39 years old (lost 5 kg)

“practical and realistic. It seemed like it was aimed at me as an overweight male. Everything else I had looked at was for women.”  42 years old (lost 11 kg)

“taught me to make small changes like reducing the snack foods I was eating and doing extra exercise. I couldn’t believe that weight loss could be so simple. 21 years old (lost 10 kg)

“This program has completely changed my life. I was really battling with my weight and health, but now I know I’m in control.”     58 years old (lost 8 kg)

Information for GPs and Health Professionals

SHED-IT (Self-Help, Exercise, Diet & Information Technology) is an evidence based Men’s weight loss program developed by internationally regarded Men’s health researcher, Professor Philip Morgan, and a team of experts in weight loss, exercise physiology, physical activity, psychology and nutrition at the University of Newcastle’s Priority Research Centre in Physical Activity and Nutrition.

SHED-IT has been specifically tailored for men and includes examples and scenarios that men can relate to and commonly experience. SHED-IT teaches men how to achieve realistic and sustainable weight loss by providing weight loss information (energy balance, calculating total energy expenditure and tracking energy intake) and outlining nine key weight loss messages.

SHED-IT instructs men in how to track their weight and waist circumference; eating and exercise and to identify and record sources of social support and personal weight, physical activity and eating goals. Men are also instructed to track their steps using the provided pedometer and aim for a weekly average of at least 10,000 steps per day. Users are advised to consult their doctor or an appropriate allied health professional prior to participating in more vigorous physical activities.

Can women use SHED-IT?

While SHED-IT is targeted specifically towards men, the information delivered in SHED-IT is also very relevant for women. In fact, many men participating in our previous SHED-IT men’s weight loss research have used the program with their wives/partners as a great way of motivating each other and losing weight together.

Please note, women who are pregnant or breast feeding should seek professional medical advice prior to using SHED-IT.
