Therapeutic weight loss techniques

The least intrusive weight loss methods, and those most often recommended by physicians, are adjustments to eating patterns and increased physical exercise. Usually, health professionals will recommend that their overweight patients combine a reduction of the caloric content of the diet with an increase in physical activity.

Other methods of losing weight include use of drugs and supplements that decrease appetite, block fat absorption, or reduce stomach volume. Surgery is another method. Bariatric surgery artificially reduces the size of the stomach, limiting the intake of food energy. Some of these treatments may have serious side-effects.

"Crash Dieting"

A crash diet (also known as "fasting") is where a person willfully restricts themselves of all nourishment (except water) for more than 12 hours. The desired result is to have the body burn fat for energy with the goal of losing a significant amount of weight in a short time. Crash dieting is not the same as flexible intermittent fasting, where dieters fast for 2 days each week and calories are cycled. Generally the weight lost in a crash diet returns when normal eating resumes.

Weight loss industry

In the developed world, there is a substantial market for products which promise to make weight loss easier, quicker, cheaper, more reliable, or less painful. These include books, CDs, cremes, lotions, pills, rings and earrings, body wraps, body belts and other materials, fitness centers, personal coaches, weight loss groups and food products and supplements. US residents in 1992 spent an estimated $30 billion a year on all types of diet programs and products, including diet foods and drinks.

Between $33 billion and $55 billion is spent annually on weight loss products and services, including medical procedures and pharmaceuticals, with weight loss centers garnering between six percent and 12 percent of total annual expenditure. About 70 percent of American's dieting attempts are of a self-help nature. Although often short-lived, these diet fads are a positive trend for this sector as Americans ultimately turn to professionals to help them meet their weight loss goals

Detox diet

Detox diet

From Wikipedia, the free encyclopedia

A detox diet is a dietary regimen involving a change in consumption habits in an attempt to "detoxify" the body, by removal of "toxins" or other contaminants. Proponents claim it improves health, energy, resistance to disease, mental state, digestion, as well as aiding in weight loss. Many scientists, dietitians, and doctors, however, regard 'detox diets' as less effective than drinking a glass of water, and view 'detox diets' as generally harmless but a waste of money.[1]

"Detox" diets usually suggest that fruits and vegetables compose a majority of one's food intake. Limiting this to unprocessed (and sometimes also non-GM) foods is often advocated. Limiting or eliminating alcohol is also a major factor, and drinking more water is similarly recommended.


Detox diets

An incomplete list of methods to modify the diet for the purpose of detoxification includes:

  • Eliminating foods that are hard on metabolism, such as caffeine, alcohol, processed food (incl. any bread), pre-made or canned food, salt, sugar, wheat, red meat, pork, fried and deep fried food, yellow cheese, cream, butter and margarine, shortening, etc., while focusing on pure foods such as raw fruits and vegetables, whole grains (excluding white rice), legumes, raw nuts and seeds, fish, vegetable oils, herbs and herbal teas, water, etc.
  • Raw foodism
  • Fasting, including water fasting and juice fasting
  • Increased consumption of fish such as salmon
  • Food combining
  • Calorie restriction
  • Herbal detox
  • Master Cleanse also known as the lemonade diet, terms coined to refer to the fasting paradigm penned by Stanley Burroughs

Some proponents of detox diets would emphasize it as a lifestyle, rather than a diet. Literary references include "Ultimate Lifetime Diet" by Gary Null advocating veganism as a (lifestyle) method of detoxification.

Criticism

Professor Alan Boobis OBE, Toxicologist, Division of Medicine, Imperial College London states that "The body’s own detoxification systems are remarkably sophisticated and versatile. They have to be, as the natural environment that we evolved in is hostile. It is remarkable that people are prepared to risk seriously disrupting these systems with unproven ‘detox’ diets, which could well do more harm than good."

There is also criticism that detox diets in general are unhealthy due to the possibility of a greater amount of natural toxic chemicals in fruits and vegetables than in animal products.[citation needed] It is argued by advocates of this perspective that the liver has evolved to do its job without assistance from such diets. However, this argument does not take into account the main focus of most detox diets, which is the sheer excess of difficult to metabolize foods that is consumed in the present day. Thus, this argument does not consider the resulting larger quantity of toxic metabolic by-products that the liver and other body systems must process.[citation needed]

The potentially high mercury content in some fish is cited to argue against increased fish consumption. If one is considering eating more fish, it is therefore important to choose fish that have low mercury levels.

Sudden changes in diet have been linked to fainting and other medical issues. It is therefore of utmost importance to gradually introduce the dietary changes, especially if they are extreme compared to the present diet. Fasting should never be undertaken without a proper understanding of its procedures, and long-term changes to the diet should always include a balance of the nutrients needed for the sustenance of the human body - carbohydrates, protein, unsaturated fat, vitamins, minerals and water. The same is adviseable for any diet, cleansing or otherwise, in order to maintain optimal health.

Highly restrictive detox diets such as Water fasting or the Master Cleanse are not the safest form of weight loss. These diets, if done improperly or for too long, may result in nutrient deficiencies. Of particular concern is lack of protein, which may result in wasting of muscle tissue, due to insufficient amino acids for repair. With less lean muscle tissue, the body's metabolic needs decrease, which hampers weight loss efforts unless calories are lessened further in the diet.

While many people have provided testimonials to their health improvements in following a "detox" diet lifestyle, some of these people may have started the detox diet after coming off an unhealthy diet high in sugar and processed food that may lack nutrients. Any improvements cited from such people would only prove the effectiveness of a detox diet over an average diet, and not that it is the ideal diet that doesn't carry its own unique health risks. It is therefore necessary to investigate whether or not the diets advocated provide sufficient nutritional value for optimal physical functioning.

Some of the changes recommended in certain "detox" lifestyles are ones that agree with mainstream medical advice, such as consuming a diet high in fruits and vegetables. Separating the beneficial effects of such changes from the rest of the recommendations made in a "detoxifying" diet is difficult.

Diet of Finland

Diet of Finland

From Wikipedia, the free encyclopedia


The Diet of Finland (Finnish Suomen maapäivät, later valtiopäivät; Swedish Finlands Lantdagar), was the legislative assembly of the Grand Duchy of Finland from 1809 to 1906 and the heir of the powers of the Swedish Riksdag of the Estates.


Åbo Lantdag

The first States of Finland were held in Helsinki in 1616.[1] Other assemblies (Åbo lantdag) where held in Turku for example in 1676. The assembly was called together by Axel Julius De la Gardie. The estate of peasants was chaired by Heikki Heikinpoika Vaanila.

The Porvoo Diet

Main article: Diet of Porvoo

During the Finnish War between Sweden and Russia, the four Estates of occupied Finland (Nobility, Clergy, Burghers and Peasants) were assembled at Porvoo (Borgå) by Tsar Alexander I, the new Grand Duke of Finland, between March 25 and July 19, 1809. The central event at Porvoo was the sovereign pledge and the oaths of the Estates in Porvoo Cathedral on March 29. Each of the Estates swore their oaths of allegiance, committing themselves to accepting the Emperor and Grand Duke of Finland as the true authority, and to keeping the constitution and the form of government unchanged. Alexander I subsequently promised to govern Finland in accordance with its laws. This was thought to essentially mean that the emperor confirmed the Swedish Instrument of Government from 1772 as the constitution of Finland, although it was also interpreted to mean respecting the existing codes and statutes. The diet had required that it would be convened again after the Finnish War, which separated Finland from Sweden, had been concluded. On September 17 of the same year, the conflict was settled by the Treaty of Fredrikshamn, but it would be another five decades until the Finnish Estates would be called again.

The Estates convene again


Not until June 1863, after the Crimean War had taken place, did Alexander II call the Estates again. On September 18 the opening ceremony was held and the Emperor made his declaration where he promised to introduce changes to the constitution. The changes included making the diet a regularly convening body, a promise which was kept by the Emperor when the diet convened again in January 1867, where it established an act on the working order of the diet. The diet was to convene at least every fifth year but in practice it would come to convene every third year. The act on Freedom of the Press was seen to have been rejected by the diet in 1867, and as a consequence censorship was introduced. The diets of the 1860s created a working and regularly convening Finnish parliament, but it also spelled an end to further promised constitutional reforms.

In the elections for the diet of 1872, members of the two language-based parties, the Fennomans and Svecomans, gained more ground at the expense of the liberals. After the assassination of Alexander II the special position of Finland in the Russian empire was in danger. Alexander III announced that the Finnish monetary, customs and postal systems were to be incorporated into their imperial counterparts. At the diet of 1882 the Governor-General gave the Emperors announcement that the diet would have the right to submit bills, but he would be the only one to initiate changes regarding the constitution and military issues.

The first period of oppression

Main article: Russification of Finland

In 1899 Emperor Nicholas II signed what was come to be known as the February Manifesto. The powers of the diet regarding Finland's internal affairs were weakened and transferred to the Russian ministers. The legal committee of the diet of 1899 adopted the opinion that the manifesto was not legally valid in Finland.

Reform

The unrest during the Russo-Japanese War resulted in a general strike in Finland in October 1905. The most immediate result was the Emperor's manifesto that cancelled all illegal regulations. A parliament based on universal and equal suffrage was also promised. An extraordinary session of the diet in December 1905 was called to implement the parliamentary reforms. The proposal was presented to the Emperor on 15 March 1906 and after his approval it was submitted to the estates on 9 May. The reforms came to force on 1 October 1906. The diet was reformed from a legislative assembly of four Estates into a unicameral parliament of 200 members. At the same time universal suffrage was introduced, which gave all men and women, 24 years or older, the right to vote and stand for election. Acts on the right of parliament to monitor members of the government, on the Freedom of Speech, Assembly and Association, and Freedom of the Press were also introduced. These reforms established the hallmarks of today's Parliament of Finland.

Composition in 1869–1906

From 1869 to 1906 the Diet of Finland was composed as follows:

  • Nobility: 201 seats; the heads of noble families had the right to sit in person or name a family member as a representative.
  • Clergy: 40 seats; included priests, university personnel and other senior teachers who elected their representatives.
  • Burghers: 30–70 seats; these were the representatives of the people living in cities, only men with taxable wealth were eligible to vote. The number of seats rose when the population of the cities grew.
  • Peasants: 70 seats; elected through indirect election in which only peasants that owned their own land (4.5% of the rural population in early 1900s) could vote.

All chambers debated separately and there were no joint sessions. Three chambers had to pass the bill before it could be approved by the Emperor.

South Beach diet

South Beach diet

From Wikipedia, the free encyclopedia

The South Beach diet is a diet plan started by Miami, Florida, area cardiologist Arthur Agatston which emphasizes the consumption of "good carbohydrates" and "good fats". Dr. Agatston developed this diet for his cardiac patients based upon his study of scientific dieting research. The diet first appeared in a book of the same name published by Rodale Press.

Dr. Agatston believes that excess consumption of so-called "bad carbohydrates", such as the rapidly-absorbed carbohydrates found in foods with a high glycemic index, creates an insulin resistance syndrome—an impairment of the hormone insulin's ability to properly process fat or sugar. In addition, he believes along with many physicians that excess consumption of "bad fats", such as saturated fat and trans fat, contributes to an increase in cardiovascular disease. To prevent these two conditions, Agatston's diet minimizes consumption of bad fats and bad carbohydrates and encourages increased consumption of good fats and good carbohydrates.

The diet has three phases. In all phases of the diet, Dr. Agatston recommends minimizing consumption of bad fats.


Phase I

The diet begins with Phase 1, which lasts two weeks. Dieters attempt to eliminate insulin resistance by avoiding high or moderately high-glycemic carbohydrates, such as dairy, sugar, candy, bread, potatoes, fruit, cereals, and grains. During this phase, Dr. Agatston claims the body will lose its insulin resistance, and begin to use excess body fat, causing many dieters to lose between 8 and 13 pounds. For the first two weeks, dieters eat normal-size helpings of meat, fish, vegetables, eggs, cheese, and nuts. This phase includes three meals a day, plus snacks, encouraging the dieter to eat until their hunger is satisfied. No alcohol is allowed (though red wine will be introduced later in small amounts). The dieter loses weight, changes body chemistry, and ends cravings for sugars and starches.

Phase I: Authorized foods

  • Beef: Lean cuts, such as sirloin (including ground), tenderloin, top round
  • Poultry: Cornish hen, turkey bacon (two slices per day), turkey and chicken breast
  • Seafood: All types of fish and shellfish (Shrimp,clams,oysters)
  • Pork: Broiled ham, Canadian Bacon, Tenderloin
  • Veal: Chop, cutlet, leg; top round
  • Lunchmeat: Fat-free or low-fat only
  • Cheese (fat-free or low fat): American, cheddar, cottage cheese (1–2% or fat-free), cream cheese substitute (dairy free), feta, mozzarella, Parmesan, provolone, ricotta, string
  • Nuts: Almonds (15), peanut butter (2 tbsp), peanuts (20 small), pecan halves (15), pistachios (30)
  • Eggs: The use of eggs is not restricted unless otherwise noted by your physician. Use egg whites and egg substitute as desired
  • Tofu: Use soft, low-fat or lite varieties
  • Vegetables: Artichokes, asparagus, beans (black, butter, chickpeas, green, Italian, kidney, lentils, lima, pigeon, soy, split peas, wax), broccoli, cabbage, cauliflower, celery, collard greens, cucumbers, pickles (dill, or those sweetened with Splenda), eggplant, lettuce (all varieties), mushrooms (all varieties), snow peas, spinach, sprouts (alfalfa), turnips, water chestnuts, zucchini, radishes
  • Fats: Canola oil, olive oil
  • Dairy: Two cups of nonfat milk or nonfat or lowfat plain yogurt are to be consumed daily
  • Spices and seasonings: All spices that contain no added sugar, broth, extracts (almond, vanilla, or others), horseradish sauce, I can't Believe It's Not Butter! spray, pepper (black, cayenne, red, white)
  • Sweet treats (limit to 75 calories per day): Candies (hard, sugar-free), chocolate powder (no-sugar-added), cocoa powder (baking type), sugar-free fudgsicles, sugar-free gelatin, sugar-free gum, sugar-free popsicles, sugar substitute.
  • Hot Sauce
  • Salsa - Limit to 2 TBS during phase 1
  • Soy Sauce - 1/2 TBS
  • Steak Sauce - 1/2 TBS
  • Worcestershire Sauce - 1 TBS
  • Whipped Topping (Light) - 2 TBS

Phase I: No-No foods

  • Beef: Brisket, Liver, other fatty cuts
  • Poultry: Chicken wings and legs, duck, goose, poultry products (processed)
  • Pork: honey-baked ham
  • Veal: breast
  • Cheese: Brie, edam, non-reduced fat
  • Vegetables: beets, carrots, corn, potatoes (white),potatoes (sweet),
  • Fruit: Avoid all fruits and fruit juices in Phase 1 including: Apples, apricots, berries, cantaloupe, grapefruit, peaches, pears
  • Starches and Carbohydrates: avoid all starchy foods in Phase 1 including: bread (all types), cereal, matzo, oatmeal, rice (all types), pasta (all types), pastry and baked goods (all types)
  • Alcohol of any kind, including beer and wine
  • No regular ketchup or cocktail sauce
  • No pork rinds - too high in saturated fat
  • No jerky - too high in sugar content
  • Limit Caffeine-Containing Beverages to 1-2 servings per day

Phase II

After two weeks, Phase II begins. Whole grain foods, fruits and dairy products are gradually returned to the diet, although in smaller amounts than were likely eaten before beginning the diet, and with a continued emphasis on foods with a low glycemic index. Sweet potatoes are also now permissible, as is red wine, both in moderate amounts.

Phase III

After the desired weight is obtained, the diet calls to move into Phase III, a maintenance phase. In Phase III the diet expands to include three servings of whole grains and three servings of fruit a day.

The diet distinguishes between good and bad carbohydrates, and good and bad fats.

  • "Good carbohydrates" are high in fiber or high in good fats, and have a low glycemic index, that is, they are digested and absorbed slowly. Other preferred carbohydrates are those with more nutritional value than the alternatives. For instance, brown rice is allowed in moderation, but white rice is discouraged. When eating any carbohydrates, Dr. Agatston recommends also eating fiber or fat to slow digestion of the carbohydrates.
  • "Good fats" are polyunsaturated and monounsaturated fats, especially those with omega-3 fatty acids. Saturated and trans fats are bad fats.

The diet emphasizes (1) a permanent change in one's way of eating, (2) a variety of foods, and (3) ease and flexibility. Eating whole grains and large amounts of vegetables is encouraged, along with adequate amounts of mono- and polyunsaturated fats, including omega-3 fatty acids, such as are contained in fish. It discourages the eating of overly refined processed foods (particularly refined flours and sugars), high-fat meats, and saturated fats in general.

The diet does not require counting calories or limiting servings; Agatston suggests dieters eat until they are satisfied. Dieters are told to eat 6 meals a day: breakfast, lunch, and dinner, with small snacks between each meal. This is different from The Zone diet in that The Zone recommends (1) a proper ratio of carbohydrates, proteins, and fats, (2) "good" carbohydrates, proteins, and fats over "bad" ones, and (3) eating portion sizes that are right for your body.[1]

South Beach Living packaged foods

Main article: South Beach Living

In 2004, Kraft Foods licensed the South Beach Diet trademark for use on a low-carb line of packaged foods called South Beach Diet. These have been renamed South Beach Living. These products are designed to meet the requirements of the diet.

Scientific studies

A 2004 study of the South Beach Diet by Agatston, et al., reviewed a 1998–1999 trial completed by 54 participants over the course of a year. A 2005 study of the South Beach Diet conducted by Kraft Foods was completed by 69 subjects over the course of just under three months. Both studies showed favorable results for the groups using the South Beach Diet.
