lavFODMAP

lavFODMAP is a term used to describe a variant of the low FODMAP diet designed to be less restrictive and easier to implement for individuals with functional gut disorders, particularly irritable bowel syndrome (IBS). The name suggests a "light" or "low-FODMAP" approach, and it is sometimes marketed or discussed in patient communities and some dietetic resources. It is not a formal clinical protocol in all guidelines, and implementations may vary.

Core approach: Like the standard low FODMAP diet, lavFODMAP aims to reduce intake of fermentable carbohydrates defined as FODMAPs: fermentable oligosaccharides, disaccharides, monosaccharides and polyols. A lavFODMAP plan typically emphasizes limiting only the most poorly tolerated foods or categories, uses a staged process including an elimination or short-term reduction phase, followed by structured reintroduction to identify individual thresholds, and focuses on maintaining nutrient adequacy.

Practical considerations: It is usually guided by a registered dietitian or healthcare provider. It may involve keeping a food and symptom diary, selecting a core set of low-FODMAP foods, and gradually reintroducing foods. It can be applied to adults and sometimes to children under medical supervision. As with the standard diet, it may reduce symptoms of bloating, abdominal pain, and altered bowel habits in some people, but responses vary.

Evidence and limitations: The low FODMAP diet has evidence for IBS symptom relief, but lavFODMAP as a distinct protocol has limited specific research. Potential downsides include restrictive eating, risk of nutritional imbalance if not supervised, and the possibility of misapplication or over-restriction. It should not replace medical evaluation for alarm symptoms or persistent weight loss.
