Eating only twice a day may help some people reduce overall calorie intake and improve weight control, but it does not automatically work better for everyone than frequent small meals. Insulin levels generally rise after any meal, and fewer meals may reduce how often insulin spikes during the day. However, obesity control mainly depends on total calorie intake, food quality, physical activity, sleep, and long-term consistency rather than meal frequency alone. Some people do well with intermittent fasting or 2 meals a day, while others feel better with smaller frequent meals. Choose an eating pattern that you can maintain comfortably and that supports balanced nutrition. Please consult a doctor or dietitian if you have diabetes, acidity, ulcers, or other medical conditions before making major dietary changes.
