From a medical perspective, carrying excess body fat, especially around the waist, increases your risk for numerous serious health conditions. However, BMI alone isn't a perfect health indicator, and your overall physical fitness and metabolic health also play significant roles.
Having overweight or obesity increases your risk of developing conditions that can lead to heart disease, such as high blood pressure, high blood cholesterol link, and high blood glucose. In addition, excess weight can also make your heart have to work harder to send blood to all the cells in your body.

The 3-3-3 rule for weight loss is a simple, habit-based method focusing on three key areas: 3 balanced meals a day, 3 bottles (or ~1.5L) of water by 3 PM, and 3 hours of physical activity per week, aiming for consistency over complex diets. It simplifies fat loss by establishing rhythm through consistent eating, adequate hydration to support metabolism, and regular movement, promoting sustainable health without intense calorie counting or restrictive rules, says Five Diamond Fitness and Wellness, Joon Medical Wellness & Aesthetics, and EatingWell.
