Losing weight through lifestyle changes has been shown to have significant long-term health benefits, without the need for surgery or medication. A recent study conducted by the University of Helsinki followed 23,000 individuals from Finland and the U.K., aged 30 to 50, over a period of 12 to 35 years. The study found that overweight men and women who lost an average of 6.5% of their body weight in early middle age and maintained it throughout the follow-up period experienced health benefits that extended beyond just preventing diabetes.
The health benefits of weight loss included a reduced risk of arterial and pulmonary diseases, as well as certain types of cancers. Professor Timo Strandberg, who led the study, emphasized the importance of weight maintenance for long-term health benefits. The results of the study were published in the journal JAMA Network Open and highlighted the importance of lifestyle changes for improving health outcomes.
The study also reinforced the idea that maintaining a body mass index (BMI) under 25 throughout life is ideal for optimal health. Professor Strandberg hopes that these findings will inspire more people to make lifestyle changes that can lead to improved health and longevity, especially in a time when obesity rates are higher than ever before.
