Effects of a vegetarian diet and treatment preference on biochemical and dietary variables in overweight and obese adults: a randomized clinical trial.

BACKGROUND: A vegetarian diet may lead to numerous health benefits, including weight loss. OBJECTIVE:We examined the joint effects of personal preference of dietary treatment and a calorie-restricted, low-fat lactoovovegetarian diet (LOV-D) compared with a standard calorie-restricted, low-fat omnivorous diet (STD-D) on changes in weight, total cholesterol, ratio of LDL to HDL cholesterol (LDL:HDL cholesterol), triacylglycerols, insulin resistance, and macronutrient intake during an 18-mo study.

A two-year randomized weight loss trial comparing a vegan diet to a more moderate low-fat diet.

OBJECTIVE:The objective was to assess the effect of a low-fat, vegan diet compared with the National Cholesterol Education Program (NCEP) diet on weight loss maintenance at 1 and 2 years. RESEARCH METHODS AND PROCEDURES:Sixty-four overweight, postmenopausal women were randomly assigned to a vegan or NCEP diet for 14 weeks, and 62 women began the study. The study was done in two replications. Participants in the first replication (N = 28) received no follow-up support after the 14 weeks, and those in the second replication (N = 34) were offered group support meetings for 1 year.

Vegetarian diet affects genes of oxidative metabolism and collagen synthesis.

BACKGROUND/AIM:A vegetarian diet is known to prevent a series of diseases but may influence the balance of carbohydrate and fat metabolism as well as collagen synthesis. This study compares expression patterns of relevant genes in oral mucosa of omnivores and vegetarians. METHODS:Quantitative reverse transcriptase polymerase chain reaction was applied for analysis of mRNA levels from carnitine transporter OCTN2, hepatic CPT1A and nonhepatic CPT1B isoforms of carnitine palmitoyltransferase and collagen (CCOL2A1) in oral mucosa.

Metabolic characteristics of breakfast-vegetarian (BV) elderly people in rural Taiwan.

Breakfast-vegetarianism (BV) is a special dietary habit in Chinese society, which is related to religious beliefs rather than health concerns. The purpose of this study was to compare metabolic characteristics of community-living middle-aged and elderly BV and non-vegetarians (NVs) in Taiwan. In 2000, people aged over 40 in I-Lan County were invited for study. In total, 367 people (mean age: 62.0+/-11.2 years, 57.8% female) participated in this study and 68 of them were BV. The BV subjects were less likely to consume oily food (29.4% vs. 43.1%, p=0.025), to smoke (5.9% vs.

A low-fat vegan diet and a conventional diabetes diet in the treatment of type 2 diabetes: a randomized, controlled, 74-wk clinical trial.

BACKGROUND:Low-fat vegetarian and vegan diets are associated with weight loss, increased insulin sensitivity, and improved cardiovascular health. OBJECTIVE:We compared the effects of a low-fat vegan diet and conventional diabetes diet recommendations on glycemia, weight, and plasma lipids. DESIGN:Free-living individuals with type 2 diabetes were randomly assigned to a low-fat vegan diet (n = 49) or a diet following 2003 American Diabetes Association guidelines (conventional, n = 50) for 74 wk.

Type of vegetarian diet, body weight, and prevalence of type 2 diabetes

OBJECTIVE:We assessed the prevalence of type 2 diabetes in people following different types of vegetarian diets compared with that in nonvegetarians. RESEARCH DESIGN AND METHODS:The study population comprised 22,434 men and 38,469 women who participated in the Adventist Health Study-2 conducted in 2002-2006. We collected self-reported demographic, anthropometric, medical history, and lifestyle data from Seventh-Day Adventist church members across North America. The type of vegetarian diet was categorized based on a food-frequency questionnaire.

Vegetarian diets and childhood obesity prevention.

The increased prevalence of childhood overweight and obesity is not unique to industrialized societies; dramatic increases are occurring in urbanized areas of developing countries. In light of the consensus that obesity is a significant public health concern and that many weight-loss interventions have been unsuccessful in the long term, an exploration of food patterns that are beneficial in the primary prevention of obesity is warranted. The focus of this article is to review the relation between vegetarian diets and obesity, particularly as they relate to childhood obesity.
