You Don't Have to Be The Biggest Loser To Achieve Weight Loss Success

Claire Collins/ The Conversation

Weight-loss ads and television shows regularly profile people who have transformed their lives through major losses of 30 kilograms or more. These weight-loss ambassadors try to inspire us to do the same by telling us they feel more alive, they can play with their kids and their confidence has grown – now they can fit into a size ten dress.

Major weight loss certainly sounds like a good plan if you’re overweight or obese and serious about improving your health. But the reality is it’s incredibly difficult to lose 30 kg, and even if you do, it’s even harder to keep off in the long term.

Instead, international guidelines commonly recommend an initial weight loss target of 10% of your starting body weight. Australia’s National Health and Medical Research Council (NHMRC) draft guidelines for the management of overweight and obesity recommend starting with a more modest weight loss goal of 5% or 5kg, whichever is higher.

For people who are overweight or have crossed over into obesity (with a body mass index or BMI of 25 to 35), a 5% to 10% weight loss is enough to improve your health and reduce risk factors for chronic conditions such as type 2 diabetes and heart disease. After two years, your risk of developing type 2 diabetes diabetes will have halved.

Some heavier people who have a BMI over 30 may need to lose15% to 20% of their weight to get the same improvement in risk profile.

Managing expectations

The strongest predictor of dropping out of a weight-loss program is starting off with an expectation of losing a really large amount of weight. So, one of the practical problems in starting the weight-loss journey is that people rarely want to limit their weight loss to 5% of their starting weight.

This 2005 study of 1,785 obese Italians is a good example. The group had a mean BMI of 38. Their maximum or “dream” weight loss goal was 32% of their starting body weight, and their minimum “acceptable” weight loss was 23%.

This weight loss expectation is five to six times more weight than is needed to improve their health, well-being and quality of life and to reduce their medication needs.

It’s therefore important for health professionals to manage their patients' weight-loss expectations. Start with a goal of 10% of initial body weight and focus on health improvement, reductions in medication use and improved quality of life. Once this has been achieved, then you can revise the goals.

Losing weight and keeping it off

The good news is that we now know a lot more about how to successfully maintain a reasonable weight loss.

2011 study of more than 5,000 Americans with existing type 2 diabetes found that almost one quarter had maintained a weight loss of 10% or more of their starting weight after four years. Importantly, success was associated with attending more treatment sessions, reporting greater adherence to the lower kilojoule diet and burning more kilojoules in physical activity.

review of the long-term weight loss trials found a mean weight loss of 3kg to 6kg (3% to 6%) was maintained in trials that extended to four years.

It’s important to note that participants regain some weight once treatment the ends. This is completely normal, and should be expected because as soon as you ease off on the kilojoule restriction or exercise routine needed for weight loss, your weight will creep back up.

Therefore, based on current research, the definition of successful long-term weight loss is being able to maintain a weight loss of 5% of your starting body weight for more than a year.

Bariatric surgery is the only intervention where weight losses greater than 10% body weight have been maintained for 10 years or longer.

Step by step weight loss

Weight loss is never easy but a little common sense can go a long way in helping you achieve your goals. If you are planing to lose weight, here are some things to keep in mind:

  1. Clarify your reasons for weight loss and identify your “dream” weight versus your “acceptable” weight

  2. Set an initial weight loss goal of 5% to 10% of your starting weight, to avoid triggering a drop out

  3. Participate fully in your diet and exercise program. The more sessions you attend or the more entries you make in web programs, the more weight you lose

  4. Enlist the help of a weight-loss professional such as a dietitian, or another person trying to lose weight

  5. Self-monitor both your physical activity and eating habits to make sure there is an increase in the kilojoules you burn up in exercise and a decrease in your kilojoules intake

  6. Hang in there – the National Weight Control Registry of people who have kept at least 13 kg off for five years report that it does get easier over time.

Finally, long-term weight loss depends on long-term lifestyle changes. Being physically active each day, reducing your daily kilojoules intake, maintain healthy eating habits on weekends and holidays, and jumping on weight rebounds when they’re small will all increase your chance of success.
