Obesity

Health Benefits of Weight Loss

Research shows the following health benefits for weight loss:

• Weight loss may improve survival in those who have an obesity-related disease, especially type 2 diabetes.³
• A modest weight loss of about 2 kg (4.4 lb) to 4.5 kg (10 lb) resulted in a significant lowering of blood pressure.⁹
• People with asthma who lost an average of 14 kg (31 lb) over 1 year showed improved lung function and overall health, and with weight loss, the number of severe asthma episodes (exacerbations) and oral corticosteroid courses were reduced.¹⁰
• People with type 2 diabetes who lost weight had lower blood sugar levels and were able to use less medicine to lower their blood sugar levels.³
• Sustained weight loss prevented new cases of type 2 diabetes in people who were obese.³
• People with obstructive sleep apnea who lost as little as 10% of their weight improved their sleep patterns and had less daytime sleepiness.³
