Carbohydrate why we need it

Generally these diets involve eating less bread and pasta and more vegetables, fruits, and meat. Although low- carbohydrate diets work well early on, after six months they do not work any better than any other diets for weight loss. As soon as you start eating carbohydrates again, your body replenishes your carbohydrate stores and your weight comes back," says Dr.

Whole grains such as whole wheat, corn tortillas, and brown rice are great sources of healthy carbohydrates. Here are ideas for getting the right carbs in your diet: Start your day with a breakfast of whole-grain cereal and fruit. Add an extra serving of vegetables to lunch and dinner. For easy between-meal snacks right at your fingertips, keep raw, cut-up vegetables in the refrigerator. Substitute beans as a main course in place of meat once every week.

Lower GI foods are less refined or processed such as wholegrains , legumes and fruit. Low-carbohydrate low-carb diets are popular because they are based on claims that carbohydrates cause weight gain. Although there are different variations, essentially low-carb diets restrict carbohydrate foods and replace them with foods usually high in protein and fat to lose weight. There are many unhealthy misconceptions about weight loss and the claims that carbohydrates can make you fat are misleading.

Weight gain comes from an excess in overall kilojoules or energy , which can come from any food source — including foods lower in carbohydrates and higher in dietary fat or protein. Typical foods eaten on a low-carbohydrate diet include — beef, chicken, bacon, fish, eggs, non-starchy vegetables, and fats such as oils, butter and mayonnaise.

Foods that are restricted include — many types of fruit, bread, cereals and other grains, starchy vegetables and some dairy products other than cheese, cream or butter. If you are on a low-carb diet, and cutting out large groups of vegetables, fruits and grains, you may not be getting enough vital nutrients to manage your weight effectively. These types of diets can increase your risk of micronutrient deficiencies and constipation because of their low fibre content.

The Australian Dietary Guidelines suggests there is a likely link between eating 3 to 5 serves of grain cereal foods each day mainly wholegrain and reduced risk of weight gain.

To maintain a healthy weight , combine a balanced diet with daily exercise. A recommended healthy diet includes:. Advocates of these diets advise people to consume kilojoules mainly from protein and fat sources — often recommending eating less than g of carbohydrate each day. Many health professionals do not support these diets as they can have a high fat content particularly saturated fat and restrict important nutrients.

Initially, low-carbohydrate diets may contribute to rapid weight loss because they restrict kilojoules or energy. The body begins to use stores of glucose and glycogen from the liver and muscles to replace the carbohydrates it is not getting from food. Around 3g of water is needed to release 1g of glycogen. Any weight loss at the beginning of a low-carbohydrate diet is mostly water, not body fat. As carbohydrate stores are used up, the body begins to rely on other sources of fuel such as fat.

This can lead to the development of ketones in the body, which can make the body acidic. It can also contribute to metabolic changes , which may be dangerous for some with certain conditions such as diabetes.

The long-term health effects of a diet very low in carbohydrates but high in saturated fat is still uncertain. Further research is needed to determine the safety of these diets. A healthy diet high in fruits and vegetables, wholegrains, legumes and low-fat dairy products, and moderate in fat and kilojoules balanced with daily physical activity, is the best way to lose weight and keep it off.

Vegetarians and people who consume generally plant-based diets are generally slimmer and have much lower rates of obesity, heart disease and cancer, than those who eat meat. However, during times of prolonged starvation or very low-carb diets, the brain shifts its main fuel source from glucose to ketone bodies, also known simply as ketones. Ketones are molecules formed from the breakdown of fatty acids. Your body creates them when carbs are not available to provide your body with the energy it needs to function.

Ketosis happens when the body produces large amounts of ketones to use for energy. This condition is not necessarily harmful and is much different from the complication of uncontrolled diabetes known as ketoacidosis. However, even though ketones are the primary fuel source for the brain during times of starvation, the brain still requires around one-third of its energy to come from glucose via muscle breakdown and other sources within the body By using ketones instead of glucose, the brain markedly reduces the amount of muscle that needs to be broken down and converted to glucose for energy.

This shift is a vital survival method that allows humans to live without food for several weeks. Summary The body has alternative ways to provide energy and preserve muscle during starvation or very low-carb diets. Fiber is a special type of carb that helps promote good digestive health and may lower your risk of heart disease and diabetes.

In general, carbs perform these functions in most people. However, if you are following a low-carb diet or food is scarce, your body will use alternative methods to produce energy and fuel your brain. Carbohydrates give your body energy to do everyday tasks.
