During ketoacidosis, the kidneys begin to excrete ketone bodies along with body water in the urine, causing some fluid-related weight loss. Ketoacidosis most often occurs in individuals with type 1 diabetes because they do not produce insulin, a hormone that prevents the overproduction of ketones.

However in a few rare cases, ketoacidosis has been reported to occur in nondiabetic individuals following a prolonged very low carbohydrate diet. The following is a summary of foods generally permitted on the diet: Allowed Strong emphasis on fats at each meal and snack to meet the high-fat requirement.

Cocoa butter, lard, poultry fat, and most plant fats olive, palm, coconut oil are allowed, as well as foods high in fat, such as avocado, coconut meat, certain nuts macadamia, walnuts, almonds, pecans , and seeds sunflower, pumpkin, sesame, hemp, flax.

Some dairy foods may be allowed. Although dairy can be a significant source of fat, some are high in natural lactose sugar such as cream, ice cream, and full-fat milk so they are restricted.

However, butter and hard cheeses may be allowed because of the lower lactose content. Protein stays moderate. Programs often suggest grass-fed beef not grain-fed and free-range poultry that offer slightly higher amounts of omega-3 fats, pork, bacon, wild-caught fish, organ meats, eggs, tofu, certain nuts and seeds.

Most non-starchy vegetables are included: Leafy greens kale, Swiss chard, collards, spinach, bok choy, lettuces , cauliflower, broccoli, Brussels sprouts, asparagus, bell peppers, onions, garlic, mushrooms, cucumber, celery, summer squashes. Certain fruits in small portions like berries. Not Allowed All whole and refined grains and flour products, added and natural sugars in food and beverages, starchy vegetables like potatoes, corn, and winter squash.

Fruits other than from the allowed list, unless factored into designated carbohydrate restriction. All fruit juices. Legumes including beans, lentils, and peanuts.

Although some programs allow small amounts of hard liquor or low carbohydrate wines and beers, most restrict full carbohydrate wines and beer, and drinks with added sweeteners cocktails, mixers with syrups and juice, flavored alcohols.

A meta-analysis of 13 randomized controlled trials following overweight and obese participants for years on either low-fat diets or very-low-carbohydrate ketogenic diets found that the ketogenic diet produced a small but significantly greater reduction in weight, triglycerides, and blood pressure, and a greater increase in HDL and LDL cholesterol compared with the low-fat diet at one year.

Despite losing a significant amount of weight on both diets, participants reported less hunger and a reduced desire to eat compared with baseline measures.

The authors noted the lack of increased hunger despite extreme restrictions of both diets, which they theorized were due to changes in appetite hormones such as ghrelin and leptin, ketone bodies, and increased fat and protein intakes.

The authors suggested further studies exploring a threshold of ketone levels needed to suppress appetite; in other words, can a higher amount of carbohydrate be eaten with a milder level of ketosis that might still produce a satiating effect? This could allow inclusion of healthful higher carbohydrate foods like whole grains, legumes, and fruit.

Their levels of ghrelin did not increase while they were in ketosis, which contributed to a decreased appetite. However during the 2-week period when they came off the diet, ghrelin levels and urges to eat significantly increased. Eighty-eight percent of the participants were compliant with the entire regimen.

Although low-carbohydrate diets were popular in the s they have resurged again yet little scientific fact into the true nature of how these diets work or, more importantly, any potential for serious long-term health risks in adopting this dieting practice appear to have reached the mainstream literature. Evidence abounds that low-carbohydrate diets present no significant advantage over more traditional energy-restricted, nutritionally balanced diets both in terms of weight loss and weight maintenance. Studies examining the efficacy of using low-carbohydrate diets for long-term weight loss are few in number, however few positive benefits exist to promote the adoption of carbohydrate restriction as a realistic, and more importantly, safe means of dieting.
