Human beings require food to grow, reproduce, and maintain good health. Without food, our bodies could not stay warm, build or repair tissue, or maintain a heartbeat. Eating the right foods can help us avoid certain diseases or recover faster when illness occurs. These and other important functions are fueled by chemical substances in our food called nutrients. Nutrients are classified as carbohydrates, proteins, fats, vitamins, minerals, and water. Although humans need food to survive, many people eat too much, or choose the wrong foods to eat, which leads to the body putting on weight. When you eat more calories than your daily energy requirements the extra calories are stockpiled as body-fat. Slowly these fat cells keep building up and settle on the hips, waist, thighs, upper arms and back, as well as around the heart, kidneys, liver and other organs. Fortunately body-fat can easily converted into energy, however, you must reduce your fat intake and exercise regularly. If you only reduce your fat and don't exercise, your body will also break down muscle tissue and use them for fuel. Many people struggle to lose weight that is put on and that's where weight loss companies come to the rescue. There are many different ways for weight to be lost, as there are many different sorts of weight loss companies. Firstly there is exercise centres such as gyms and recreation centres which focus on fitness as the key to lose weight, Many varieties of pills, tablets and vitamin supplements are available that claim to make you lose weight. Meal replacement programs are available where the consumer has a liquid drink instead of a meal and this provides them with necessary nutrients. Diet plans are commonly found in magazines as well as the more common weight loss centres which some supply you with foods to eat and others inform you and assist you in making wise food choices. Whatever weight loss program is chosen the consumer will be required to move more and eat less which can be a common mis-conception in overweight people wanting to lose weight. Overweight people sometimes have the wrong attitude towards weight loss and many think its 'impossible' or will involve them having to do too much. This is where the advertising of the weight loss centres comes in promising them that they can still eat cake and chips and keep their quality of life. Another problem overweight people can have is that they often seek weights that may be biologically impossible to achieve or, if achieved, cannot be maintained. Weight loss centres can help overweight people reach their ideal weight by giving them mental help as well as physical help. The centres inform people of good nutrition and appropriate food choices and many combine support sessions with information sessions and some hold exercise sessions as well. To lose weight a person basically needs to exercise more and start eating a balanced and plenty of healthy foods. Although this may sound simple, a weight loss program will help an overweight person achieve their weight loss goals through advice and support they would not otherwise receive.
