Filter by:Background: Obesity treatment should be individualized since some calorie restricted diet doesn't work for some individuals. Objective: we assess the effect of two different calorie restriction with MediterrAsian diet on weight loss of FTO rs9939609 carriers with overweight. Methods: we recruit 80 healthy overweight participants aged 20-45 years that randomly allocated in two interventional group [group 1: Mediterrasian diet according to adjusted ideal body weight with 500 calories restriction (RD) and group 2: without 500 calories restriction (NRD)+ Moderate physical activity]. Anthropometric indices will be assesses for all participants weekly for two month. The criteria for weight loss is 250-500 grams weekly. Metabolic indices, physical activity and psychologic aspects will be assesses at baseline and the end of the intervention. Dietary adherence will be checked by 24hr recalls at day 0, 30 and 60. At the end of the study, we compare carriers with different alleles (AA+TA and TT) in two intervention groups to find out which calorie restriction is appropriate for each genotype. Significant p-value is less than 0.05.
Bread is the most common grain product in the world, with consumption surpassing 3 billion individuals per year. Sourdough whole-grain bread is considered a healthy alternative to white, refined-wheat bread. This cross-over study will test the effect of consumption of sourdough bread compared to white bread following a short dietary intervention period (one week) on multiple clinical parameters and gut microbiota.
It is not known whether different lentil varieties have the same efficacy in lowering blood glucose. Similarly, the carbohydrate component of lentils responsible for lowering blood glucose is not known, nor is the bioavailability of lentil metabolites and polyphenol bioactive.
This study examined how dieting with a partner affects weight loss, diet adherence, psychological well-being, and cortisol.
The Summer Electronic Benefit for Children (SEBTC) demonstration provided food assistance to households with school-aged children during the summer through electronic benefit transfer (EBT) procedures used by the Supplemental Nutrition Assistance Program (SNAP) and Special Supplemental Nutrition Program for Women, Infants and Children (WIC) programs. The evaluation design included two components: an impact study and an implementation study. The evaluation assessed the impact of SEBTC on children's food security and nutritional status, household food expenditures and purchasing behaviors, parental perceptions, and participation in nutrition assistance programs. The implementation study analyzed SEBTC use patterns using administrative data, and described demonstration implementation and costs.
In the 19th century, researchers found out that the differences in the energy content of macronutrients (protein, carbohydrate and fat) can elicit different responses in the amount of calories individuals burn per day. It was demonstrated that protein has a metabolic advantage when compared to the other macronutrients (carbohydrate and fat). Since these findings, researchers all over the world started to study how diets differing in macronutrient distribution could result in different responses to energy metabolism. Diets with high amounts of protein (i.e. meats, eggs, dairy products, and grains) are becoming more popular, and studies have shown that when people eat high quantities of protein they lose weight and fat mass, maintain the weight loss, and burn more calories per day. The investigators hypothesize that giving high amounts of protein to healthy women will increase the amount of calories and fat they burn per day, increase their satiety, and improve health markers when compared to a normal diet. The increased protein level will be achieved using a nutrition supplement consisted of soy protein, yogurt and honey. To test this, the investigators plan to divide the participants in two groups: one will eat a normal diet and the other a diet with high amounts of protein during one and a half day. After one month they will change groups and eat the other diet for the same period of time. During this period consuming the diets (1.5 days), participants will stay inside a whole body calorimetry suite, which is similar to a hotel bedroom and is able to inform in the most precise way the amount of calories participants will burn and if they are burning more fat. Additionally, before and after each meal participants will have to answer a questionnaire about their appetite sensations and blood will also be collected to analyze health markers.
This survey is a multicenter, double-blind, randomized, controlled, parallel-designed, prospective trial and is intended to evaluate the Bimuno GOS effects on growth, tolerance, gut health, fecal flora and immune function.
To provide "prescriptions" for weekly Community Supported Agriculture (CSA) boxes of fruits and vegetables to patients, accompanied by nutritional education (e.g. printed newsletters and YouTube videos), and evaluate benefits for participants by exploring commitment to the program, opinions about healthy eating, retention of nutrition and food preparation knowledge, overall takeaway from the program, as well as self-assessment of health status. To establish the overall feasibility of an effective "prescription produce" program for at-risk and underserved patients - called "ProduceRx" - by utilizing produce from regional farms in addition to the resources of the Penn State Health System and an interdisciplinary team of healthcare workers (dietitians, dietetic interns, and medical students). To provide a proof-of-concept for this model (i.e. ProduceRx + interdisciplinary approach to health education) for other healthcare institutions.
Objective: To compare short-term and medium-term effectiveness of a multimodal program that integrates a program of therapeutic exercise, medication review, adequacy of diet and health education, compared with standard medical practice in improving neuromuscular and physiological status on frail elderly. Another aim is to analyze the maintenance of these effects by monitoring long-term (12 months) from the start of the intervention. Design: Randomized controlled trial Scope / Study subjects: recruited frail elderly in Basic Health Zone of Malaga. Methods: The subjects to be included in the study (after meeting inclusion / exclusion) will be randomized into two groups: a control group whose intervention will be to review medication + adequacy of diet + health education (physical activity recommendation (within a comprehensive advice on healthy lifestyles) and an experimental group whose intervention will be a Multimodal Intervention: therapeutic exercise + review medication + adequacy of diet + health education program. Sociodemographic, Clinical and monitoring Variables will be collected at baseline. Moreover, tracking variables will be collected at 2 and 6 months after starting the intervention and at 3 and 6 months after the end of the intervention (monitoring). The monitoring variables that will be measured are: BMI , general health, fatigue, brittleness, Motor Control, Attention - Concentration - Memory, Motor Memory , spatial orientation, grip strength, balance (static - semi-static and dynamic ), gait speed and metabolomic variables. One descriptive analysis of the sociodemographic variables of the participants will be performed. Further the change on the variables intra-subjects (pre-post intervention) and inter-subjects (experimental group vs control group) will be calculated. For the intra-subject analysis will be performed a ANOVA-one factor analysis. The intersubject outcome variables will be compared between the two groups in each moments of data collection, using the student t-test or Wilconxon (depending of the sample distribution). The level of significance was set at P ≤ 0.05.
In this parallel group study, participants were randomized to either 1 of 3 conditions (a) fruit and vegetable consumption, (b) dietary fat and added sugars, or (c) physical activity.
