Brian First "Quality care begins with a clear understanding of a patient's specific concerns. In the household of Henry Stafford in , gentle members received 2. As I have said before, you have to be committed to the program to get results, but as long as you follow their plan you will lose weight! Everyone requires different amounts of energy each day, depending on age, sex, size, and activity level. Bread consumption was high in most of Western Europe by the 14th century.
The calories found in the average alcoholic drink are quite concentrated compared to many foods, and this actually causes one to inadvertently take in many more calories than would otherwise be consumed. Alcohol is quite deceptive in that it passes through the system rapidly, often before the drinker is aware of the number of drinks they have had. Alcoholic drinks also contain calories from other sources, which add to overall caloric intake. Certain cocktails, for example, contain fats. Wine and beer both have high carbohydrate content.
An example of how many calories can be easily consumed can be seen with a small glass of wine: Beer contains more carbohydrates although many of the "Lite" beers have a carb content similar to a glass of wine and less alcohol than wine, but is seen as being more fattening, due to its higher energy content. While drinking, people usually will not stop to consider the impact alcohol is having on their bodies; such is alcohol's affect on loosening the inhibitions. The result of this relaxed thinking could mean more calories consumed and extra body fat gains.
Those drinking might also eat more of the wrong kinds of food, without thinking of the consequences. Alcohol tends to have an appetite stimulating effect as it provides little in the way of nutrition, leaving a craving for other foods at the time of consumption. Add this to the fact that fatty and salty foods tend to accompany most occasions featuring alcohol as well as alcohol actually stimulating one's appetite for these kinds of foods , and the general loosening of resolve that goes with an inebriated mindset, and you have a recipe for excess fat gain.
Given alcohol is a by-product of yeast digestion; it can have an irritating effect on the lining of the stomach and gradually weaken the kidneys and liver, leading to serious health problems—even death in certain instances.
Any weakening of the stomach will lessen the rate and efficiency at which food is digested, which ultimately interferes with a healthy metabolism and the weight loss process. The liver—which processes toxins and breaks down fats for fuel—is crucial when it comes to maintaining a healthy body composition. Alcohol is at its most destructive during the liver's detoxification process. Testosterone, which has a powerful fat loss effect, is reduced whenever alcohol is consumed, thus halting its full potential as a fat burner.
Also, testosterone as an anabolic hormone, contributes to gains in lean muscle mass. Lowered testosterone means fewer muscle gains, and less muscle means a lowered metabolic rate. A lower metabolic rate will make the job of losing fat all the more harder. This is what governs the way we use energy. Those with a higher metabolic rate will burn more calories at rest.
By interfering with testosterone production, alcohol indirectly causes the body to lower its metabolic rate and thus the rate at which it uses energy and directly prohibits testosterone from exerting its powerful fat-burning effects. Touched on briefly in point two, alcohol can increase appetite, making the combination of alcohol and a fattening meal all the more worse. A Canadian study showed that alcohol consumed before a meal increased caloric intake to a far greater extent than did a carbohydrate drink.
Also, researchers from Denmark's Royal Veterinary and Agricultural University showed that if a group of men were given a meal and allowed to eat as much as they wanted, alcohol, rather than a soft drink, would increase the amount of food consumed.
To gain an understanding of why alcohol affects us the way it does, it is important to known how it is processed in the body. Alcohol is generally absorbed fairly rapidly, but its absorption can be quickened depending on several factors:. The amount of alcohol in a standard drink will take around 10 hours for the average person to process, which means the more that is consumed at any one point, the greater the rise in blood alcohol content.
When the liver processes alcohol, it does so in one of two ways. For the most part, alcohol is broken down by the enzyme alcohol dehydrogenase ADH, which is contained in the liver cells. ADH then metabolizes the alcohol into acetaldehyde. Acetaldehyde is broken down into acetate by another enzyme, aldehyde dehydrogenase. In the final stage, the acetate is further metabolized to where it eventually exits the body as waste products carbon dioxide and water.
The other way alcohol can be processed is a less common alternative, which uses a different set of liver enzymes. This alternative pathway, called the microsomal ethanol-oxidizing system, is used when the blood has very high levels of alcohol.
The alcohol content of our most popular beverages varies, so it is important to know exactly what percentage of alcohol is in any given drink if one is wanting to limit all the empty calories. The following percentages are usually contained in each standard drink—five ounces of wine, 12 ounces of beer or 1. If you really have to drink, what are the best choices?
Some lower calorie brands to hit the market are showing promise, as are some of the more traditional alternatives. As shown above, total caloric content of various alcoholic drinks varies, with beer generally containing the highest number, considering the smaller amount of alcohol found in this drink compared with others. Various spirits also known as liquor generally contain around 64 calories per nip, but these do add up depending on the strength of the drink for example, a double will contain two nips, or calories.
Wine generally contains around to calories per medium sized glass. It also contains more alcohol than beer given the same volume, making it a better choice calorie-wise, as less would be consumed at any one sitting. Liqueurs, although usually around calories per nip, are often consumed with other, often-higher calorie mixers such as coke or milk to make cocktails, bumping the calorie content way up.
It is usually consumed nips at a time given its lower alcohol strength. The calorie content described on food labels refers to kilocalories. A calorie chocolate bar actually contains , calories. The United States government states that the average man needs 2, kcal per day and the average woman needs 2, kcal per day. Not everybody needs the same number of calories each day.
People have different metabolisms that burn energy at different rates, and some people have more active lifestyles than others. Here is a more detailed breakdown from the U. The human body needs calories to survive. Without energy, the cells in the body would die, the heart and lungs would stop, and the organs would not be able to carry out the basic processes needed for living.
People absorb this energy from food and drink. If people consumed only the number of calories needed every day, they would probably have healthy lives.
Calorie consumption that is too low or too high will eventually lead to health problems. The number of calories in food tells us how much potential energy they contain. It is not only calories that are important, but also the substance from which the calories are taken. As an example, here is the breakdown of how a person would get calories from one cup of large eggs , weighing g:.
As people get older, they tend to get fewer of their daily calories from fast foods. Fast foods make up only 6 percent of the daily calorie intake of older adults. However, with the number of highly calorific meals served in restaurants or aimed at younger individuals, it is important that people pay close attention to where they get their calories. Researchers at Tel Aviv University wrote in the journal Obesity that a large breakfast containing approximately kcal is ideal for losing weight and lowering the risk of diabetes , heart disease , and high cholesterol.
A large breakfast may help to control body weight. When people eat matters as much as what they eat. Empty calories are those that provide energy but very little nutritional value. The parts of food that provide empty calories contain virtually no dietary fiber, amino acids, antioxidants , dietary minerals, or vitamins.
Added sugars and solid fats are said to make foods and drinks more enjoyable. However, they also add many calories and are major contributors to obesity. Alcohol can also contribute empty calories to the diet. One normal serving of beer can add kcal to a person's intake for the day. If beer is not your drink of choice, you can use this calorie calculator provided by the National Institute on Alcohol Abuse and Alcoholism to work out how many calories alcohol adds to your diet.
The following foods and drinks provide the largest amounts of empty calories:. More than half of all people in the U. Approximately 5 percent of people in the U. This is the equivalent of more than four cans every day. There are ways of sourcing products with less solid fat or empty sugars.
Rather than choosing the standard hot dog or a fatty cheese, for example, a person could choose low-fat options for either. However, even the lower-fat options are no replacement for calories consumed from sources that also provide nutritional benefit.
Most Americans don't have much room in their diets for a completely nutrient-void beverage. One recent study showed that drinking more than one sugar-sweetened beverage a day increases your risk of high blood pressure. It's better if you can avoid them altogether and instead consume water, fat-free or 1 percent fat milk, percent fruit juice, and low-sodium vegetable juices.
The intake of empty calories can be avoided or dramatically reduced by incorporating fresh, healthy food and drink into the diet. Calories seem to be linked only to weight gain and obesity, but they are vital for health. They only pose a health risk when people consume more than the recommended amount. When thinking about calories, you should not be considering just your diet but also your level of physical activity. A high intake of calories can be countered with regular, high-intensity exercise.
