Can BMI over thirty be reduced?
Generally, a BMI over 30 can be reduced, and the key lies in using scientific methods and maintaining consistency. Caution is required when underlying medical conditions are present. If in doubt, it is advisable to consult a healthcare professional in advance. The detailed explanation is as follows:

A BMI exceeding 30 falls within the obesity range. With a well-designed plan and long-term commitment, most individuals can gradually lose weight. By controlling diet—reducing intake of high-calorie and high-sugar foods—and combining regular physical activity, such as aerobic exercises along with strength training, a calorie deficit can be created to promote fat burning. Additionally, adjusting sleep patterns and improving unhealthy habits lead to more stable weight loss results and enhance overall health.
However, special considerations apply in certain cases. If serious underlying conditions such as cardiovascular or cerebrovascular diseases or joint injuries are present, attempting weight loss without guidance may increase physical strain. It is essential first to treat the primary condition and then develop a gentle, individualized weight-loss plan under professional supervision. Moreover, extreme dieting, lack of exercise, or frequently giving up midway not only reduce the likelihood of success but may also lead to weight regain and even impair metabolic function; these pitfalls should be avoided.
Prior to starting weight loss, a comprehensive health checkup is recommended to understand one's physical condition. Under the guidance of a physician or registered dietitian, create a personalized diet and exercise plan, progressing gradually and avoiding the temptation to achieve rapid results.
