A good diet is important for good health. A healthy and varied diet can help to maintain a healthy body weight, enhance general wellbeing and reduce the risk of a number of diseases including heart disease, stroke, cancer, diabetes and osteoporosis.
A healthy diet consist of four main categories of foods - of course there are some other minor groups. But these four main food groups will provide a healthy diet the bulk of its nutrition. They are: vegetables and fruits, grain products, milk products, and meats and alternatives.
A healthy diet will serve a good balance of each of the food groups listed. Of course, different individuals will need different amounts of food. Other factors such as age, body size, activity level, gender will also affect the amount of food you eat. Below is a guide to provide you with a general idea of how much from each group you should serve for a healthy diet.
Please note that meat is NOT a necessary part of a healthy diet. Contrary to what many say, you can get enough proteins from vegetables, beans and soy products.
A healthy diet is a diet based on breads, potatoes, and other cereals and is rich in fruits and vegetables. A healthy diet will include moderate amounts of milk and dairy products, meat, fish or meat/milk alternatives, and limited amounts of foods containing fat or sugar.
You must have carbohydrate, protein, fat, vitamins, minerals salts and fibre in the correct proportions. If there is not enough protein, you will not be able to grow properly and you will not be able to repair yourself i.e. wounds will not heal properly. If you do not have enough energy containing foods you will feel very tired, you will not have enough energy. If you have too much energy containing foods you will become overweight.
If you think that you are overweight you might try taking more exercise to "burn off" some of the excess food which you ate at you last meal.
The Zone Diet works on the principle that 100,000 years ago, we were meat eaters, and our metabolism is designed to handle the demands of a meat-based diet.
Madonna, Demi Moore, and Jennifer Aniston swear by the results of the Zone Diet, which was created by Barry Sears, PhD. The Zone Diet contains 40% carbohydrate, 30% protein, and 30% fat and is known as the 40-30-30 plan.
As the food industry evolved, more carbohydrates have been introduced into our daily diet, thus causing an imbalance in our metabolism to burn fat. The reason for our extra weight can also be attributed to the many grains and starches in our diet (pasta, rice, breads, and potatoes). The Zone Diet's approach calls for a return to the diets of our ancestors where meat, fruits, and vegetables are the main dietary foods.
The Zone Diet suggests that you need the right ratio of carbohydrates to proteins and fats in order to control the insulin in the bloodstream. Too much of the hormone (insulin) can increase fat storage and inflammation in the body (conditions that are associated with obesity, type 2 diabetes and heart disease). Sears asserts that by using the Zone Diet, you are actually optimizing the body's metabolic function. Through the regulation of blood sugar, you allow your body to burn excess body fat.
Although you are not prohibited from any particular food group, it is best to avoid food with high fat and carbohydrates such as grains, starches, and pastas. The ideal sources of carbs are fruits and vegetables and for monounsaturated fats olive oil, almonds, and avocados are recommended. The Zone Diet claims to use food as a drug for overall good health, weight loss and prevention or management of heart disease and diabetes.
Sears says that you can test to see whether you are 'hormonally' correct by eating following the Zone diet and see how you feel four hours later. To simplify the Zone Diet, fill one-third of a plate with low-fat protein, and then two-thirds with fruits and vegetables.
Celebrities and some health experts say that the Zone's recommendations do not stray far from the USDA's (United States Dietary Association) dietary guidelines and therefore are advocates of the Zone Diet. Others argue that the Zone Diet has flawed ratios but Sears argues that the Zone diet is a low-glycemic-load diet that has adequate protein. .
A critic of the Zone diet such as the AHA (American Heart Association) classifies the Zone Diet as high protein and does not recommend the Zone Diet for weight loss. They contend that the Zone Diet has not been proven effective in the long term for weight loss. The AHA issued an official recommendation warning against diets like the Zone Diet. They believe that the Zone Diet is hazardous as it restricts the intake of essential vitamins and minerals present in certain foods. The AHA also contends that the protein ratio in the Zone diet is too high even if the minimal fat ratio is good. Robert H. Ecker M.D of the A.H.A. finds the Zone Diet's theory on insulin flawed and argues that there is no scientific proof that the hormone insulin plays a big role in weight regulation.
If you know someone that has been trying to lose weight and get into shape, you have probably heard words such as, "I just eat one meal a day to lose weight" or "I'm afraid if I eat, I'll gain weight" but sadly, this misnomer is why so many people are in the "battle of the bulge". People all over the world still believe that eating breakfast, or even three meals a day will cause them to gain weight. In truth, as long as they are eating the right types of foods and exercising, then three normal meals or six small meals a day will actually work better with their metabolism than eating the wrong quantities or not eating often enough.
With more than half of Americans over the age of 20 now being considered "overweight", now more than ever, we need to understand how metabolism works in relation to losing weight. Why risk having a heart attack, a stroke, developing cancer, or diabetes when all you have to do is make a few minor changes and live a healthy life? First, a person's metabolic rate is determined by the number and size of respiring cells that compromise the body's tissue, and the intensity of the metabolism in these cells. These two factors combined are what makeup the physiological foundation of the amount of energy (calories) in which a body uses.
Keep in mind that energy cannot be created or destroyed, just changed. As we know, potential energy comes from the foods we eat. When talking about weight loss, there are three components of balanced energy, which include calorie intake, calories stored, and calories expended. The way it works is that if the amount of calories taken in equals the amount of calories being expended (burned), then there is balance and the body's weight is stable.
On the other hand, if the balance becomes positive, caused by more food being eaten than is burned, energy is destroyed or in better terms, stored as body fat. It is important to remember that you can be eating a diet considered low-fat and still gain weight. The reason is that most dietary fat is stored while the body is burning carbohydrates and proteins for energy. The problem is the when a person gains weight, the increased level of fat becomes stored energy until the calorie balance is negative. For that to happen, the amount of calories burned needs to exceed the number of calories being consumed, no matter what the macronutrient content.
Metabolism is the rate at which the body uses energy to support the basic functions essential to sustain life. This metabolism is comprised of three parts, which include physical activity (20%), Thermic Effect of Food, also called TEF (10%), and Resting Metabolism Rate or REM (70%). Physical activity is the amount of energy your body burns up during normal, daily activities to include housework, recreation, work, exercise, and so on. Obviously, someone that is physically active will burn more energy than a sedentary person will. TEF accounts for the energy used in digesting and absorbing nutrients, which would vary depending on the meal's composition. When a person overeats, TEF is increased because more food must be digested. Here is where metabolism becomes very interesting and what causes so much confusion.
One pound is equal to 3,500 calories, so let us say a person consumes 3,500 more calories than normal. That individual would not gain one pound because the TED is accounted for but if 3,500 calories were cut trying to lose weight, then TEF decreases since there would be fewer nutrients to process. The result is that with energy expenditure would decrease, meaning that the individual would lose less than one pound in weight. In other words, by cutting out too much food, TEF cannot work as it was designed to do. Now keep in mind that you cannot go around eating a bunch of junk food. After all, the calories you do consume need to be healthy foods but what this does mean is that when you do not eat, you are actually working against your body in fighting weight gain, not the other way around.
Finally, the RMR refers to the number of calories the body needs to run its essential functions, as well as chemical reactions while in a rested state. This aspect of metabolism accounts for the greatest number of calories burned every day. What happens is that if lean weight should be lost because of increased protein metabolism, then RMR decreases. Typically, you would see this happen when a person goes on a very strict diet. In this situation, the body is forced into a negative nitrogen balance, which means a greater amount of protein is lost than what is replaced because of less protein/energy intake. When this imbalance occurs, there is a gradual loss of lean weight, which then lowers RMR.
What happens many times is that dieters will limit the amount of lean weight loss with intense exercise for the muscles to develop a need to maintain more protein. When this happens, the body is forced to use more energy from stored fats. If you want to put your metabolism to work for you, some simple steps can be taken:
* By adding a few extra pounds of lean muscle, the metabolic rate can be increased by up to 200% each day * Remember that lean weight can burn as much as 20 times more calories than fat weight * Regular exercise is one of the best ways to boost metabolism * By eating smaller meals and more often, you can boost your metabolism rate
While you need to eat healthy foods, studies prove that what matters most is how much of a person's body weight is attributed to fat. Remember, excess fat is what links to major health problems. Therefore, it is important that you maintain a healthy weight but more crucial that you monitor the fat-to-muscle ratio.
For example, a woman standing 5'5" might weigh only 125 pounds but have a 27% body fat ratio, which is not good. This individual worked hard to diet, while staying involved with aerobics. However, much of what she lost was not fat, but muscle. Even though this weight would be considered ideal for her height, her body fat to muscle ratio is too high.
An excellent way to optimize your fat-to-muscle ratio is by getting involved with weight training in addition to the nutrition and cardio. As you will see with the tools provided at www.comptracker.com, you can analyze the thickness of the subcutaneous fat at various areas of the body. The benefit is that you know exactly what your ratios are so you can achieve a healthy fat-to-muscle ratio as well as body weight.
Remember, you are in control and need to make the decision to do something good for yourself. Therefore, now is the time to take that control and fight to live a lean and healthy lifestyle.
Do you love to eat fatty foods? If so, then you could be a candidate for certain heart related problems. According to medical studies, the incidence of heart attacks and coronary artery disease is a result of an escalation of blood cholesterol levels. For that reason, people with cholesterol levels that are above the norm should protect themselves from suffering any form of degenerative disease by lowering their blood cholesterol. This can be realized by observing a low cholesterol diet, while at the same time engaging in moderate physical activities. If diagnosed with high cholesterol levels, there is also medication that can help in controlling cholesterol levels.
Having an excess of cholesterol in the blood is suggested by medical experts as the number one cause of hypertension, and heart disease. In general, the concept that cholesterol is harmful for the body is definitely a false impression. Cholesterol is an important component in our body’s complete metabolism. It functions as a vital substance in the formation of cell membranes and also is responsible in producing vitamin D and other significant hormones in the human body. However, an increase in cholesterol levels may damage our entire physical condition. For this reason, controlling cholesterol is important.
Most doctors tell their patients who suffer from high cholesterol to lower their cholesterol level. This can be achieved by following a diet that is low in fat. Watch out for foods that are high in cholesterol and fats; adding non-fat and low-fat foods to the diet also helps. Also one of the best solution in controlling cholesterol is through exercise. In some instances, your doctor may prescribe drugs that can also help lower cholesterol levels.
What kind of dietary practice should you adopt?
First and foremost, observing a diet that contains less fat and less cholesterol is the key for controlling cholesterol. Here are some tried-and-tested tips in maintaining a healthy heart:
1. Eat in moderation. Excess amounts of food can lead to an increase inweight.
2. Stay away from fatty foods.
3. Steer clear of sweets, especially pastries for they are identified as a principal source of saturated fats.
4. Eat more vegetables. Vegetables contain vitamins and minerals, which are cholesterol-lowering elements.
5. Boost your fiber intake. Fiber-rich foods are also known to lessen cholesterol in the blood.
6. Keeping active while on a low-cholesterol diet is also a contributory factor in controlling cholesterol.
7. For more effective tips in controlling cholesterol, seek advice from your physician. He or she may need to prescribe medications to lower your cholesterol.
Practicing healthful eating habits can greatly add to your overall fitness. And so, controlling cholesterol through diet really makes a difference to your whole wellbeing.
If you have high cholesterol, you should consult your primary care physician prior to making any changes in your diet or lifestyle.
If you ask any child about the adults around them, they'd probably say we're a little wacky and seem to be stressed out a lot of the time. Here are a few simple things they can teach us...
1. Nap when you're tired.
2. Eat when you're hungry.
3. Don't starve yourself, it makes you tired and cranky. Eat little bits often to keep fueled up.
4. Stubbornly refuse to eat even one more bite once you're full. If you're full after a few bites, gleefully throw the rest away.
5. Leave the table with a satisfied, full belly and an eagerness to dive back into your delicious life.
6. Be picky and only eat foods you love. If it doesn't taste great to you, clamp those lips shut and refuse to eat until something better is found.
7. Be in awe over how amazing and wonderful your body is. Notice how it moves, hugs, plays, loves, heals, and enjoys life.
8. Run, jump, skip, play. Move your body because it's so much fun and it feels good. Be amazed at all the incredible physical things your body can do.
9. Wear clothes that are comfy and that make you feel good.
10. Appreciate the people around you for who they are rather than for how they look.
11. Hang out with fun, friendly people and stay away from mean, critical ones.
12. Feel great about yourself because, well, why wouldn't you?
If you don't have a two-year old around right now, seek one out and watch them for a day. Their simple enjoyment of life, and their absolute respect for their own bodies is something to aspire to.
