The Beginner's Guide to the 5: Some find it more satisfying to focus on consuming low-calorie dense foods in large quantities versus counting calories. The meal plans and recipes can be useful for those who need some guidance on what to eat.

They do this by weighing your general health concerns against the risks and potential complications of drastic calorie reduction. A diet like this has risks and precautions associated with it. A doctor should supervise you while on this diet. Some people use a calorie diet as part of the recently popularized 5: Under this plan, you eat a balanced Mediterranean-style diet of about calories for five days of the week and then limit yourself to low-carbohydrate calories per day for the other two days.
There is very little evidence to support the benefits of 5: You can get an idea of how much or how little calories is when you consider the calorie count of popular foods.
The USDA calculates that two handfuls of peanuts or a slice of pepperoni pizza contains about calories. An apple contains fewer than 80 calories, while two pieces of fried chicken contain about calories. You might also want to consider how many calories you burn in a day.
According to the Harvard Medical School , a pound person burns 72 calories by just sitting in a one-hour meeting. One of the problems with a calorie diet is that it places no limits on the fats and carbohydrates you consume. A serving of chocolate pound cake and a glass of milk adds up to about calories.
Regardless of calorie count, a well-rounded diet includes fruits and vegetables, lean proteins, and whole grains. Being healthy is about a lot more than just a number.
The greatest dangers associated with a calorie diet relate to vitamin and mineral deficiencies. Vitamin and mineral deficiencies can lead to many health problems. In fact, most people cannot meet their vitamin and mineral requirements if they eat less than calories per day. For example, according to the Mayo Clinic , if your diet lacks the mineral zinc , which is in pumpkin seeds and beef, you can suffer hair loss.
Low iron intake can lead to anemia , while chronic low intake of calcium and vitamin D can lead to osteoporosis later in life. Always consider the full nutritional makeup of the foods you eat, not just their calories. A calorie diet can also put you at danger for muscle loss. At first, muscle loss may seem like you are losing more weight, but keep in mind that not all weight is bad. To keep your body healthy, you need to be able to build muscles.
A healthy diet burns fat, not muscle. Another health risk to keep in mind when considering a calorie diet is that your metabolism will change when you reduce the amount of calories you eat for a long enough period of time.
Severe calorie restriction for prolonged periods of time will lead to a slower metabolism. This can lead you to burn fewer calories. Also, when you lose weight, you then need fewer calories to maintain your new weight than you needed for your original weight.
But if they do so, they will regain weight until they reach their original weight. Though you may lose weight, you are at risk of malnutrition , which can cause many health problems. The level of effort needed to use this diet is considered "high" as there are many foods that need to be excluded. According to the traditional acid ash hypothesis underlying this diet, acid ash is produced by meat, poultry, cheese, fish , eggs , and grains. Alkaline ash is produced by fruits and vegetables, except cranberries, prunes and plums.
Since the acid or alkaline ash designation is based on the residue left on combustion rather than the acidity of the food, foods such as citrus fruits that are generally considered acidic are actually considered alkaline producing in this diet. Advocates for alternative uses of an alkaline diet propose that since the normal pH of the blood is slightly alkaline, the goal of diet should be to mirror this by eating a diet that is alkaline producing as well. These advocates propose that diets high in acid-producing elements will generally lead the body to become acidic, which can foster disease.
Because of the body's natural regulatory mechanisms, which do not require a special diet to work, eating an alkaline diet just can, at most, change the blood pH minimally and transiently. A similar proposal by those advocating this diet suggests that cancer grows in an acidic environment, and that a proper alkaline diet can change the environment of the body to treat cancer.
This proposal ignores the fact that while cancer tissue does grow in an acidic environment , it is the cancer that creates the acidity. The rapid growth of cancer cells creates the acidic environment; the acidic environment does not create cancer.
The role of the diet and its influence on the acidity of urine has been studied for decades, as physiologists have studied the kidney 's role in the body's regulatory mechanisms for controlling the acidity of body fluids.
The French biologist Claude Bernard provided the classical observation of this effect when he found that changing the diet of rabbits from an herbivore mainly plant diet to a carnivore mainly meat diet changed the urine from more alkaline to more acid. Spurred by these observations, subsequent investigations focused on the chemical properties and acidity of constituents of the remains of foods combusted in a bomb calorimeter , described as ash.
The "dietary ash hypothesis" proposed that these foods, when metabolized , would leave a similar "acid ash" or "alkaline ash" in the body as those oxidized in combustion. Nutrition scientists began to refine this hypothesis in the early 20th century, emphasizing the role of negatively charged particles anions and positively charged particles cations in food.
Diets high in chloride , phosphate and sulfate all of which are anions were presumed to be acid forming, while diets high in potassium , calcium and magnesium all of which are cations were presumed to be alkaline forming. Other investigations showed specific foods, such as cranberries , prunes and plums had unusual effects on urine pH.
While these foods provided an alkaline ash in the laboratory, they contain a weak organic acid, hippuric acid , which caused the urine to become more acidic instead. Historically, the medical application of this diet has largely focused on preventing recurrence of kidney stones as well as the prevention of recurrent urinary tract infections , by relying on the recognized ability of this diet to affect urinary pH.
Years ago, this diet was used to adjust the acidity of the urinary environment that the stones formed in, and could hypothetically help prevent stones from forming or the development of UTIs. However, the analytical methods that attempted to precisely calculate the effects of food on urinary pH were not precise except in very general terms, making effective use of this diet difficult. Therefore, medications , which can more reliably alter the urine pH, rather than diet modification, have been the treatment of choice when trying to alter the pH of the urine.
Precise calculations require very detailed knowledge of the nutritional components of every meal as well as the rate of absorption of nutrients, which can vary substantially from individual to individual, making effective estimation of urine pH still not currently feasible.
