11 Research-Backed Habits to Prevent Heart Disease

4. Maintain a healthy weight and waist size

Excess body weight — especially central fat around the waist — increases blood pressure, insulin resistance, and bad cholesterol levels, all of which raise heart disease risk. Research shows that even modest weight loss, such as 5–10% of body weight, can meaningfully improve these markers. Instead of crash diets, focus on gradual, sustainable changes: reduce portion sizes, choose whole foods over processed items, and make small swaps in your tiffin or meal prep that lower calories without removing cultural favorites. For example, swap a fried snack for roasted makhana or include an extra serving of vegetables with dal and rotis. Monitor progress with waist measurement and weekly weigh-ins, and set realistic monthly goals that prioritize body composition and fitness over quick numbers. Combine dietary shifts with regular activity and strength training; increasing muscle mass helps you maintain long-term weight loss. If you struggle with persistent weight despite changes, consult a clinician or dietitian to rule out medical contributors and to get tailored support.
