One of the big changes in his diet pattern was he stopped eating mindlessly. From fried savoury snacks such as samosas, dosas and cheese toast he switched to consuming less than 1,700 calories day. Weight loss occurs when you consume fewer calories than your body expends, creating a calorie deficit. This deficit prompts the body to use stored fat for energy, resulting in weight loss over time. To achieve a calorie deficit, you can reduce your caloric intake through portion control, choosing nutrient-dense foods, and avoiding high-calorie snacks. Additionally, increasing physical activity helps burn more calories, contributing to the deficit. However, it’s essential to maintain a balanced diet and avoid excessively restrictive measures to ensure adequate nutrition. Consistently maintaining a calorie deficit, combined with healthy lifestyle habits, leads to sustainable weight loss.
