But before you set out to follow this weight-loss regime, you should know that you are not going to lose pure body fat. Due to the calorie deficit required to burn each kilo of fat, it is not possible to lose 4.5 kg of pure body fat in just one week. Although a lot of the weight you lose will certainly comprise body fat, you will tend to shed kilos by dropping excess water weight from your body. This is because the plan involves lowering your insulin levels and ridding your body of stored carbs that hold water.
Eat regular meals or snacks every 2-4 hours. Skipping meals isn’t the answer to losing weight, and it may even derail your efforts. Food gives you energy, so going too long without eating can leave you feeling tired, which decreases your activity level. Additionally, it triggers your body to crave high-calorie, high-sugar snacks for a quick energy boost. Instead of starving yourself, plan frequent, healthy meals.[3]
Ultimately, long-term weight loss requires some short-term behavior change and healthier habit formation. That's why we created our Good Housekeeping Nutritionist Approved Emblem, which exists to help turn smart food choices into healthier eating habits. All GHNA foods and drinks make it easier to find — and eat — good-for-you foods without additional time, effort, and cost. We target the lifestyle-related factors that make healthier eating hard, and find simple but creative solutions that actually work! Look for the emblem on labels wherever you shop for food.

Add a cup of low-fat milk, a part-skim mozzarella stick, or a half cup of low-sodium cottage cheese to breakfast, and you may have a belly-busting win. While lots of research links calcium with lower body weights, results from a 2014 study suggest that calcium-containing foods may reduce waist circumference in those genetically predisposed to carrying weight in their midsection.
