No potato or anything. Fasts lasting a day or two are unlikely to be dangerous for most healthy adults. The dinners are done very nicely with foods that are very tasteful and full of flavor. I started on Nutrisystem exactly 2 months ago with a week lapse. The program is really simple to follow and my carb, sugar and salt cravings are gone.

There's no face-to-face support, but you get support through online message boards and a mentor program that connects newbies with an experienced member. Also, you can reach a registered dietitian or personal trainer by phone at any time.
The optional meal delivery service offers freshly prepared, calorie-controlled meals delivered by FedEx. But telephone support has some evidence in its favor: Yes, it's a bargain for round-the-clock support. For about the same money, other services offer better track records.
For the first two weeks, you eat three extremely low-carb meals a day plus mandatory snacks. After that, you gradually add "good carbs," such as fruits and whole grains. You can customize menus, search a database of more than 1, recipes and get a personalized shopping list. There's online support from staff dieticians and members plus daily motivational emails.
Studies have shown that after one year, carb-restricted diets led to greater weight loss and increased heart health than low-fat diets. However, the advantage disappeared over the long term. How much can you expect to lose? Figure on 8 to 13 pounds during the two- week kick-start phase, then 1 to 2 pounds a week thereafter.
It doesn't cost much, but you don't get as much support as with Weight Watchers or eDiets. The Zone diet is mostly meat, fruits, and vegetables. You eat three meals per day plus two Zone protein-powder snacks. A study of people in the Journal of American Medical Association found the Zone diet helped people achieve modest weight loss after one year, comparable with those on the Atkins , Weight Watchers and Ornish diets, and improved cardiac risk factors.
Premium-priced Jenny Craig lets you order its heart-healthy, nutritionally balanced packaged food by phone and pick it up at a Jenny Craig center or have it delivered through Jenny Direct. You eat three Jenny Craig meals plus a snack per day, and supplement with fruit, vegetables and dairy. Once a week, you get a weigh-in and pep talk with a consultant - who is not a dietician and who earns commissions from selling you products.
There's also round-the-clock phone support. Jenny Craig has a good track record for short-term weight loss up to one year. In a UC San Diego clinical trial of dieters funded by Jenny Craig , Jenny Craig clients lost 11 percent of their initial weight after 12 months, compared with 3 percent weight loss by those who were dieting on their own. The "doctor-designed" Bistro M. The price is a cut above the competition, too. The plan tries to help you avoid a weight-loss stall out by varying the daily calorie intake between 1, and 1, By eating a little more some days and a little less on others, you'll supposedly prevent your body from becoming used to the same number of calories every day.
While no university studies support the theory that varying caloric intake aids weight loss, the high quality of the food and the relatively large portion sizes have been praised by Health magazine, Dr. Phil and The New York Times. Some plan users have complained of a lack of choices and menu flexibility compared to other plans, but a company spokesman says they offer more than entrees and can make substitutions to accommodate allergies and food preferences.
It's a reasonable price for well-made food with slightly faster average weight loss than with Jenny Craig. This meal-delivery service, endorsed by Marie Osmond and Dan Marino, emphasizes foods with a low glycemic index. The underlying premise is that controlling blood sugar levels leads to weight loss.
The heat-and-eat prepared meals and snacks contain roughly 55 percent "good" carbs, 25 percent protein, and 20 percent fats; like Jenny Craig, you add fruits, vegetables and dairy. Support is available through phone counseling and online chat rooms. There's plenty of research showing that following a diet of 1, to 1, calories a day, such as Nutrisystem, can cause weight loss. For example, a study by the Obesity Research Center at St.
Luke's Roosevelt Hospital in New York found that postmenopausal women who followed a 1,calorie plan for 16 weeks lost an average of 21 pounds. For a meal-delivery diet system, Nutrisystem is more economical than Jenny Craig. Although today's program is not as stringent as the original liquid fast Medifast launched decades ago, the low-fat, relatively low-carb plan is designed to bring about rapid weight loss by coaxing your body into a "fat-burning state" known as ketosis.
The 70 meal replacement choices include shakes, bars, soups, pudding, oatmeal, chili, pretzel sticks, cheese puffs, and scrambled eggs.
If you can stick with it, a diet of 1, calories a day can certainly induce rapid weight loss. A common concern with such low-calorie diets is that you'll quickly regain the weight, but in a small clinical trial recently published in the journal Experimental Biology , after 10 months, only about one in five people regained all the weight they had lost.
Choose this more extreme plan only if quick weight loss is your priority.

Thom Tillis on "Face the Nation". 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.
