Indian doctors have recently unveiled comprehensive new guidelines aimed at combating the growing obesity epidemic in the country. These guidelines, published in the Diabetes & Metabolic Syndrome: Clinical Research & Reviews, outline two distinct stages of obesity and recommend tailored lifestyle interventions for each stage.
Obesity is categorized into two stages:
Stage 1 Obesity: Defined as an elevated body mass index (BMI) above 23 kg/m², but without causing significant impact on organ function or daily life. While this stage doesn’t yet pose immediate health risks, it can potentially progress into more severe forms of obesity if left unchecked.
Stage 2 Obesity: Characterized by a BMI greater than 23 kg/m² along with an increase in abdominal fat, larger waist measurements, or a high waist-to-height ratio. This stage is associated with substantial physical and health problems, such as joint pain, particularly in the knees, and obesity-related diseases like type 2 diabetes.
Diagnostic Approach
A thorough obesity evaluation involves a detailed review of a patient’s medical history, a physical examination, and necessary diagnostic tests. This process helps identify secondary causes of obesity and uncover related health complications.
Stage 1 Obesity: Preventive Measures
For individuals in Stage 1, the emphasis is placed on personalized nutrition plans, regular physical activity, and behavioral modifications. These lifestyle adjustments are often sufficient to prevent progression to Stage 2. However, for those at higher risk, such as individuals with a family history of diabetes or heart disease, medication may be recommended. Medications may also be advised for those who experience significant weight gain (10% or more) despite lifestyle interventions or for individuals with a BMI of 27.5 kg/m² or higher.
Stage 2 Obesity: Intensive Management
Stage 2 obesity requires consistent, intensive lifestyle changes. These include:
Dietary Management:
Caloric Restriction: Reducing calorie intake to establish a negative energy balance is key to effective weight loss. A calorie deficit of about 500 kcal per day, through a combination of diet and exercise, is typically recommended.
Dietary Approaches: Low-carbohydrate and ketogenic diets are particularly effective for short-term weight loss, especially for individuals accustomed to high-carb diets. Long-term dietary efforts focus on protein-rich foods or supplements to promote fat metabolism and prevent weight regain.
Physical Activity:
Exercise Routine: Physical activity plays a crucial role in weight loss by preserving muscle mass and improving overall health. It should be combined with dietary adjustments to sustain a negative energy balance. The goal is at least 60 minutes of daily physical activity, which can include a mix of aerobic and resistance exercises.
Individuals should avoid prolonged periods of inactivity and gradually increase exercise intensity. Pre-exercise health checks are necessary for those with underlying medical conditions.
Pharmacological Support:
Medication: Medications may be used in conjunction with lifestyle changes to help achieve a 5-10% reduction in body weight within 3-6 months. However, weight regain is a possibility once medication use is discontinued, so realistic weight loss goals should be set. Medications should be weight-neutral or promote weight loss, avoiding those that might encourage weight gain.
In India, approved anti-obesity drugs include orlistat and GLP-1 receptor agonists, with orlistat being the most commonly available treatment.
Conclusion
With obesity rates on the rise, these new guidelines offer a structured approach to managing and preventing obesity, with an emphasis on personalized, sustainable lifestyle changes. By targeting both early and advanced stages of obesity, doctors aim to curb the health consequences of this growing epidemic and improve overall public health outcomes.
