Every year new fad diets come along. The grapefruit diet, cookie diet, low carb diet, diets using shakes, and hormone injection diets have all come and gone. Many people are able to lose some weight on these diets, unfortunately most eventually put it all back on. Diets do not work. Most are too restrictive. Many leave you hungry or tired. So is weight loss hopeless? Should we all give up and have a triple scoop ice cream sundae instead? No!! Your goal should be a healthy lifestyle. Being healthy includes keeping your weight down, but should also reduce your chances of chronic diseases including heart attacks, strokes, and cancer. Losing weight should not mean risking your health at the same time. The key to a healthy lifestyle and sustained weight loss is the concept of calorie density. Calorie density refers to the amount of calories in a set amount of food, usually per gram. Some foods have a low calorie density (for example, 1 calorie per gram) and other have a high calorie density (for example, 10 calories per gram). Your goal is to eat as many foods every meal with the lowest calorie densities. Therefore, you end up getting full on less calories. You do not want to be hungry – which is a critical point. Hunger always eventually leads to binge eating. For example, think of your stomach as a round fish bowl. If you fill it with peanuts, you will have eaten approximately 2500 calories. If instead, you fill it with bananas, you will have eaten only about 500 calories. In both instances you are full and cannot eat anymore. By eating bananas instead of peanuts you have received 5x less calories. By choosing foods that are lower in calorie density you fill up with less calories which will lead to weight loss. So which foods have the lowest calorie density? Those that are filled with water and fiber. Fruits and vegetables top the list. You can eat vegetables all day long and lose weight. You get filled up way before over-eating too many calories. The same goes for fruit. Every meal should include a variety of fruits and vegetables. Your snacks should involve fruits and vegetables. It is impossible to get fat on carrots or peppers. On the other hand fats, oils, and processed foods are quite calorie dense. You get a lot of calories for a small amount of food. Oils, for example have 120 calories per tablespoon. Processed foods are highly calorie dense. When food manufactures process foods they remove the water and fiber. This creates foods that are loaded with calories in a small amount of food. Corn has few calories. Corn chips are loaded with calories. Potatoes are lower in calories. Potato chips are loaded with calories. Processed foods are unhealthy and calorie dense. Many vitamins and nutrients are also removed when foods are processed. The more you avoid them the better off you will be. The more your food looks like when it came out of the ground the better. Your daily goal should be 10 servings of fruits and vegetables. Your stomach has only so much room. Fill it up with healthy fruits and vegetables and there will be little room for the highly processed, calorie dense foods. Start to think about this concept at every meal. Your daily calorie intake will decline as will your weight. We will be discussing this concept of calorie density further in later posts including discussing other foods that are low in calorie density. We will also be exploring a closely related topic – nutrient density. Remember, fill up on healthy low calorie foods and the weight will start to come off and stay off.
