Let’s get started! You’re not alone!
There are 600 million overweight adults and 100 million overweight children worldwide. Its prevalence has doubled from 5.1% in year 1992 to 10.8% in 2010. This is accompanied by a parallel rise in the prevalence of Diabetes Mellitus. According to the latest studies on obesity, at least 80% of them has tried at least once to lost weight and about 50% of them are motivated to lose weight.
Your Health Can't Wait. We’ll walk this journey together!
Overweight issue is further compounded by weight bias and obesity stigma. Living with the risks of coming down with many weight-related diseases, they often do not seek medical attention early. Weight bias by some Healthcare Professionals further impedes many from providing timely quality medical care.
What is Obesity?
Obesity indicates abnormal physiology where there is surplus intake of energy resulting in an elevated body weight, the set point of which is now dysfunctional. Mismatch of 3% can lead up to 1-2kg of weight gain per year. Our body weight is tightly regulated by a complex homeostasis where deviation from the set point triggers a compensatory response in the opposite direction trying to restore this set point. This compensatory response can persist for years further predisposing an individual to further weight re-gain beyond the initial weight loss.
The Importance of Multi-level and Individualized Approach in Weight Management
Losing 3,500 kcal per week will not result in a 0.5kg/week weight loss indefinitely because this does not factor in the homeostatic mechanism that resists further weight loss. The same diet and exercise plan will not be sufficient to maintain this deficit per week as the declining weight will mean declining energy expenditure due to compensatory homeostatic response. Therefore multi-level approach would include not just lifestyle and behavioral modifications but also possible combination of pharmacologic and even bariatric surgery based on individual’s medical risk assessment.
Main Goals in Weight Treatment Journey
The main goal of therapy is to treat and prevent weight-related complications. The optimal treatment will be based on individual risk and severity of weight-related complications such as Diabetes Mellitus, Osteoarthritis, Ischaemic Heart Disease, Non Alcoholic Fatty Liver Disease and Obstructive Sleep Apnea.
