Nutrisystem is a weight loss program that provides all your meals prepackaged through the mail. These foods are designed by a nutritionist to eliminate the need to plan your diet program. Both Lean Cuisine and Nutrisystem provide prepackaged meals that complement a well-balanced diet and weight-loss program. All meals are designed by nutritionists for proper nutrition with low calorie content. Both meal programs provide foods that are easy to prepare and do not take a long time to cook.

Lean Cuisine foods are available in the frozen food section of the grocery store. They do not create your weekly meal choices or offer any packaged snack foods, daily meal choices or daily dietary fresh food requirements. Nutrisystem foods are ordered monthly and are delivered to your home. All meals are planned out in advance. You choose your meal options from breakfast, lunch, dinner, snacks and dessert sections on the monthly food order form, according to the Nutrisystem website. Except for personal choices, Nutrisystem is designed so you do not have to design a diet meal plan.

Both plans require that you purchase fresh vegetables and fruits in addition to the regular meals. Lean Cuisine has limited support services. You need to register to use the tools. The support is mostly in FAQ question-and-answer format with nutrition and exercise advice provided as well. The Nutrisystem tools consist of weight and measurement logs, progress tracker, food diary, meal planner, grocery guide, dining-out guide and an exercise tracker.

Over many years, there have been multiple observations that ingestion of certain short-chain carbohydrates, including lactose, fructose and sorbitol, fructans and galactooligosaccharides , can induce gastrointestinal discomfort similar to that of people with irritable bowel syndrome. These studies also showed that dietary restriction of short-chain carbohydrates was associated with symptoms improvement.

These short-chain carbohydrates lactose, fructose and sorbitol, fructans and GOS behave similarly in the intestine. Firstly, being small molecules and either poorly absorbed or not absorbed at all, they drag water into the intestine via osmosis. It is this 'stretching' that triggers the sensations of pain and discomfort that are commonly experienced by IBS sufferers. This was proposed to reduce stimulation of the gut's nervous system and provide the best chance of reducing symptom generation in people with IBS see below.

At the time, there was no collective term for indigestible or slowly absorbed, short-chain carbohydrates, so the term 'FODMAP' was created to improve understanding and facilitate communication of the concept.

A systematic review in adult and paediatric population, on behalf of Italian Society of Pediatrics".

Ital J Pediatr Systematic Review. Nat Rev Gastroenterol Hepatol Review. An emerging body of research now demonstrates the efficacy of fermentable carbohydrate restriction in IBS. Whether the effect on luminal bifidobacteria is clinically relevant, preventable, or long lasting, needs to be investigated.

The influence on nutrient intake, dietary diversity, which might also affect the gut microbiota, and quality of life also requires further exploration as does the possible economic effects due to reduced physician contact and need for medication. Although further work is required to confirm its place in IBS and functional bowel disorder clinical pathways, fermentable carbohydrate restriction is an important consideration for future national and international IBS guidelines.

A comprehensive systematic review and meta-analysis". J Gastroenterol Hepatol Review. Common symptoms of IBS are bloating, abdominal pain, excessive flatus, constipation, diarrhea, or alternating bowel habit.

These symptoms, however, are also common in the presentation of coeliac disease, inflammatory bowel disease, defecatory disorders, and colon cancer.

Confirming the diagnosis is crucial so that appropriate therapy can be undertaken. Unfortunately, even in these alternate diagnoses, a change in diet restricting FODMAPs may improve symptoms and mask the fact that the correct diagnosis has not been made. This is the case with coeliac disease where a low-FODMAP diet can concurrently reduce dietary gluten, improving symptoms, and also affecting coeliac diagnostic indices.

Misdiagnosis of intestinal diseases can lead to secondary problems such as nutritional deficiencies, cancer risk, or even mortality in the case of colon cancer.
