A healthy lifestyle is important in CVD prevention and treatment through effects on modifiable CVD risk factors, particularly blood pressure. Although the major drawback is the low level of adherence over time, appropriate lifestyle changes may safely and effectively prevent and treat hypertension. The recommended dietary approaches that have been shown to be capable of reducing blood pressure are: salt restriction, moderation of alcohol consumption, high consumption of vegetables and fruits and low-fat and other types of diet, and weight reduction...

 The present study was conducted to establish pharmaceutical intervention guidelines to enable hospital pharmacists to provide optimal pharmacotherapy to cancer patients. Many patients who use oral anticancer agents showed favorable drug compliance but insufficient drug adherence. It was demonstrated that in order to improve drug adherence, it is important to conduct interventions tailored to the patients' conditions so as to encourage interest in their medications, as well as to gain their understanding on the necessity and the side effects of their medications...

BACKGROUND: Alternate-day-fasting (ADF) has been proposed as an effective dieting method. Studies have found that it also can increase life span in rodents, and reduce inflammation in humans. The aim of this paper was to systematically review the efficacy of ADF compared to very-low-calorie dieting (VLCD) in terms of weight loss, and reduction of fat mass and fat-free mass. METHODS: Systematic review: PubMed literature searches were performed. Fixed review procedures were applied...

Background. Obesity and its comorbidities continue to challenge the world at an alarming rate. Although the long term solution lies on lifestyle changes in the form of dieting and exercising, drug, medical food, or dietary supplement interventions are required for those who are already obese. Here we describe a standardized blend composed of extracts from three medicinal plants: Morus alba, Yerba mate, and Magnolia officinalis for appetite suppression and metabolic disorders management. Method. Extracts were standardized to yield a composition designated as UP601...

The thyroid is one of the metabolism regulating glands. Its function is to determine the amount of calories that the body has to burn to maintain normal weight. Thyroiditides are inflammatory processes that mainly result in autoimmune diseases. We have conducted the present study in order to have a clear picture of both autoimmune status and the control of body weight. We have evaluated the amount of either thyroid hormones, or antithyroid, or anti-microsomal, or anti-peroxidase antibodies (Abs) in patients with high amounts of Abs...

OBJECTIVE: The mechanisms by which bariatric surgeries so effectively and lastingly reduce body weight and normalize metabolic dysfunction are not well understood. Fibroblast growth fator-21 (FGF21) is a key regulator of metabolism and is currently considered for treatment of obesity. Although elevated by acute food deprivation, it is downregulated after weight loss induced by chronic calorie restriction but not after Roux-en-Y gastric bypass surgery. Therefore, the goal of the present study was to assess the role of FGF21-signaling in the beneficial effects of Roux-en-Y gastric bypass surgery (RYGB)...

OBJECTIVE: A major challenge for obesity treatment is the maintenance of reduced body weight. Diet-induced obese mice are resistant to achieving normoweight once the obesogenic conditions are reversed, in part because lowered circulating leptin leads to a reduction in metabolic rate and a rebound of hyperphagia that defend the previously elevated body weight set point. Because hypothalamic POMC is a central leptin target, we investigated whether changes in circulating leptin modify Pomc expression to maintain normal energy balance in genetically predisposed obese mice...

The purpose of this investigation was to assess the influence of calorie restriction (CR) alone, higher-protein/lower-carbohydrate intake alone, and combined CR higher-protein/lower-carbohydrate intake on glucose homeostasis, hepatic de novo lipogenesis (DNL), and intrahepatic triglycerides. Twelve-week old male Sprague Dawley rats consumed ad libitum (AL) or CR (40% restriction), adequate (10%), or high (32%) protein (PRO) milk-based diets for 16 weeks. Metabolic profiles were assessed in serum, and intrahepatic triglyceride concentrations and molecular markers of de novo lipogenesis were determined in liver...

BACKGROUND: The role that dietary interventions can play in multiple sclerosis (MS) management is of huge interest amongst patients and researchers but data evaluating this is limited. Possible effects of a very-low-fat, plant-based dietary intervention on MS related progression and disease activity as measured by brain imaging and MS related symptoms have not been evaluated in a randomized-controlled trial. Despite use of disease modifying therapies (DMT), poor quality of life (QOL) in MS patients can be a significant problem with fatigue being one of the common disabling symptoms...

OBJECTIVES: Omega-3 (ω-3) fatty acids have potential positive effects during chemotherapy, such as body weight maintenance and muscle mass preservation. However, little is known about the effect this supplement might have on reducing chemotherapy-induced toxicities. The aim of this study was to determine the usefulness of ω-3 fatty acid supplementation in the reduction of chemotherapy-related toxicities. METHODS: Sixty-one patients undergoing neoadjuvant chemotherapy for esophageal cancer randomly received ω-3-rich enteral nutrition (EN; n = 31) or ω-3-poor EN support (n = 30) for 15 d during chemotherapy...

Smoking to control body weight is an obstacle to smoking cessation, particularly in western cultures where diets are often rich in calories derived from fat sources. The purpose of this study was to investigate the effects of continuous nicotine administration on meal patterns in rats fed a high-fat diet. Male rats were housed in cages designed to continuously monitor food intake and implanted with minipumps to deliver approximately 1.00 mg/kg/day of nicotine or saline. Meal patterns and body weights were assessed for 2 weeks of treatment and 1 week posttreatment...
