Terms applied to such eating habits include "junk food diet" and "Western diet". Many diets are considered by clinicians to pose significant health risks and minimal long-term benefit. This is particularly true of "crash" or "fad" diets—short-term, weight-loss plans that involve drastic changes to a person's normal eating habits.

A vegetarian diet is one which excludes meat. Vegetarians also avoid food containing by-products of animal slaughter , such as animal-derived rennet and gelatin. A desire to lose weight is a common motivation to change dietary habits, as is a desire to maintain an existing weight.

Many weight loss diets are considered by some to entail varying degrees of health risk, and some are not widely considered to be effective. This is especially true of "crash" or "fad" diets. Many of the diets listed below could fall into more than one subcategory. Where this is the case, it is noted in that diet's entry.

A very low calorie diet is consuming fewer than calories per day. Such diets are normally followed under the supervision of a doctor. Crash diet and fad diet are general terms. They describe diet plans which involve making extreme, rapid changes to food consumption, but are also used as disparaging terms for common eating habits which are considered unhealthy. Both types of diet are often considered to pose health risks.

Where this is the case, it will be noted in that diet's entry. Detox diets involve either not consuming or attempting to flush out substances that are considered unhelpful or harmful. Examples include restricting food consumption to foods without colorings or preservatives, taking supplements, or drinking large amounts of water.

The latter practice in particular has drawn criticism, as drinking significantly more water than recommended levels can cause hyponatremia. Some people's dietary choices are influenced by their religious, spiritual or philosophical beliefs. People's dietary choices are sometimes affected by intolerance or allergy to certain types of food. There are also dietary patterns that might be recommended, prescribed or administered by medical professionals for people with specific medical needs.

This means that products do not have to undergo studies proving to the FDA that they are safe or effective before being sold.

If you are considering using a dietary supplement for weight-loss, it is best to take a list of its ingredients to a healthcare professional or pharmacist to determine if the product is right for you. Weight-loss results from dietary supplements are often difficult to measure as there are many supplements available that may or may not work in conjunction with another weight-loss strategy, such as exercise or changes in dietary restrictions.

As with any weight-loss program, a one to two pound per week weight-loss is recommended for safety and health. Thus, it is not uncommon to see ads for dietary supplements claiming that you can lose weight rapidly without changing the way you eat, or without lifestyle changes.

The influence of celebrity promoters can contribute to the perception that a product may offer a miracle cure for obesity. In fact, good scientific evidence that they work is generally lacking. There are many different devices available and all come with a host of options, such as online tools, smartphone apps and more. This in turn allows them to make adjustments accordingly. Body monitors are significantly more accurate than pedometers, which only measure steps taken and not the intensity of activities.

Body monitoring devices alone will not result in weight-loss. These devices are meant to be used along with a weight-loss option. The benefit of using a body monitor is that a wearer will get a good understanding of which of their activities burn calories best.

The downside is that food logging can become tiring, and the ability of a body monitor to accurately calculate calories depends entirely on how well the wearer tracks their food consumption. In addition, not everyone wants to wear an armband or carry a device at all times. How does it work? It is the only FDA-approved weight-loss medication that is available OTC and available at a higher dose with a prescription. It is a capsule that is usually taken three times per day before a meal that contains dietary fat.

It works by decreasing the amount of fat your body absorbs. The average weight-loss is about 5 percent of your weight after one-year.

In a person who weighs pounds, this would mean 10 pounds of weight-loss. It does not work well for people who are already on a low-fat diet since their calories from fat are already low. Common side effects are cramps, gas, stool leakage, oily spotting and gas with discharge that improve with a lower fat diet. Utilizing a commercial weight-loss center or program is one of the most popular options for someone affected by obesity.

Commercial weight-loss programs often provide various resources such as pre-packaged meals, support and more. Programs usually offer a 1, to 1, calorie-per-day diet plan which produces weight-loss of about pounds per week.

The slow-down of weight-loss is not unique to these approaches. It is true of any weight-loss program because as you begin to weight less, you burn fewer calories. Because commercial plans vary greatly, the FTC recommends asking the following questions before engaging in a program:.

In this section, we will examine some of the most popular commercial weight-loss programs by separating them into two different categories: Meal Replacements Meal replacement through pre-packaged meals can be appealing because of the convenience and ease of choices they offer.

However, when meals are pre-packaged, participants may not learn the basics of nutrition and healthy eating. Pre-packaged meals may also be expensive this claim is dependent on the normal weekly food cost an individual could incur. Liquid meal replacement plans, if used for too long, may be harmful because they can cause nutritional deficiencies. Unfortunately, when participants have not learned the principles of healthy eating and portion control, they often resume prior eating patterns.

Non-meal Replacements Some programs do not require meal replacement as part of their program. Their main goal is to teach you about healthy eating patterns, behavior modification and incorporating physical activity.

While it is helpful long-term, behavior change does not happen overnight and can be a challenging adjustment at first. Overall, a safe and effective commercial program will offer educational materials that have been reviewed by a licensed healthcare professional. These materials will include information on healthy eating plans, exercise and behavior therapy.

Nutrisystem features portion-controlled foods and structured meal plans that are both high in protein and low in glycemic index GI. Low-GI means means that the foods do not cause your blood sugar to rise sharply. For people with diabetes, a low-GI diet can help keep blood glucose in control. Nutrisystem plans, tailored for men and women, encourage you to consume three meals and two or three snacks per day. The plans offer about different pre-packaged to choose from.

Foods are home-delivered, typically in shipments every four weeks, after you place an order online or over-the-phone. You have to purchase additional fruits, vegetables and dairy products on your own.

These are grouped into three categories: Smartcarbs nutrient-rich, high-fiber carbohydrates , PowerFuels lean proteins and healthy fats and vegetables non-starchy ones which can be eaten freely. A meal planner explains how and when to add these foods into your diet. The program has an active online community, including discussion boards and dietitian-led chats. Counseling, for those who want it, is available and included with most Nutrisystem programs.

With the recommended fruits, vegetables and dairy products, this diet plan can be considered well-balanced. Research on Nutrisystem customers showed an average weight-loss of 18 pounds at three months and 27 pounds at six months. Some research finds a small weight-loss advantage for low-GI diets over high-GI ones, but other studies find no difference. So, this should be a healthy way to lose weight. Another concern is that participants using pre-packaged meals do not necessarily learn good nutrition, which makes maintaining weight-loss difficult once they return to buying food on their own.

Counselors are also available throughout the program and during transition and maintenance to educate about good eating habits. The final concern is the cost of the food. This does not include the additional fruits, vegetables and other foods that you must purchase on your own. Although Nutrisystem claims that the full cost of eating while on the program is about 15 to 40 percent less than what the average American spends on food, some consumers would rather buy food week-to-week.

Some employers and health plans subsidize or reimburse program costs. The program is developed by registered dietitians in consultation with an expert Science Advisory Board.

The program is delivered by trained personal consultants in weekly motivational one-on-one consultations, in center, over the phone or via Skype. Consultants partner with members to identify personal motivators, set weekly menu and activity plans, monitor progress, overcome obstacles and positively reinforce success. A typical menu day on Jenny Craig consists of three meals and three snacks per day, which, in combination with the added grocery items, adds up to an individualized menu calorie level that is based on your gender, age, height, weight and level of physical activity.

The standard menu caloric distribution is percent carbohydrate, percent fat and percent protein. For the Jenny Craig for type 2 diabetes menu, the caloric distribution is 45 percent carbohydrate, 30 percent fat and 25 percent protein. For the first half of your program, you primarily follow menus that include Jenny Craig foods for seven days a week.

For special events or other times when you need an alternate option, your consultants will offer guidance for meals on your own. When you have lost half of your total weight-loss goal, you make the transition to five to six days of menus that include Jenny Craig foods and one to two days of your own foods.

Throughout your program, you work with your consultant to utilize behavioral strategies to address challenges like emotional, social and unconscious eating and dining out, as well as to build an enjoyable, active lifestyle.

Jenny Craig is a well-balanced, scientifically proven program on which you can expect to lose pounds per week on average. A clinical trial of people with type 2 diabetes demonstrated a 9 percent weight-loss at one year with greater improvements in diabetes control and heart risk factors as compared to usual care.

For both programs, Jenny Craig participants achieved three times greater weight-loss when compared to usual care. The daily menu is a model for learning nutritional balance, variety and moderation in food choices.

Counselors are not dietitians. However, they have been trained to deliver an evidence-based program that is developed by registered dietitians and recommended by the Obesity Guidelines.
