First, as someone who has done this for a few years now, "calorie restriction" is not recommended. The "eat less move more" approach to losing weight is a long term failure, because it assumes a one-compartment model for calories that doesn't exist in reality. Do not, I repeat, do not, count calories, or abstain from eating to satiety when you're hungry. It only serves to slow your metabolism, and make you cold and miserable.
Do eat a ketogenic, or at least a low-carbohydrate diet, and eat infrequently (fast, but eat to satiety, once or twice a day). The reason for this is that of the three macronutrients, carbs, proteins, and fats, carbohydrates trigger the production of the most insulin by far, with (healthy, monounsaturated or polyunsaturated) fats resulting in the least insulin production. Insulin is the fat regulating hormone, and the high-carb western diet and frequency of eating, and snacking results in an abundance of insulin in the body, which results in insulin resistance, and thus more fat storage.
The starving kids in India are malnourished, not fasting, a profound difference.
