Filter by:The purpose of this study is to investigate the effects of daily supplementation of OLECOL for a period of 8 weeks on cardiovascular risk markers.
The objective of this study is to determine the effect of a high protein, high fiber supplement pre-load on energy intake at a subsequent meal compared to a low fiber, high carbohydrate Control product in healthy overweight and obese subjects. The investigators hypothesize the high protein, high fiber pre-load will result in reduced energy intake at a subsequent meal compared to low protein, low fiber.
The project proposes to provide the Complete Health Improvement Program (CHIP) initially up to 25 adult (non-pregnant) Ohio University employees (and/ or their adult family members) with with diabetes / prediabetes, obesity / overweight, hypertension / prehypertension, atherosclerotic cardiovascular disease, or dyslipidemia in an effort to improve self-management and the consequences of biometric factors that can be modified by lifestyle changes. The CHIP program is an educationally based, lifestyle intervention program that aims to reduce healthcare cost, absenteeism, and increase employee productivity. The investigators expect that participants following the programs guidelines will lower their body mass index, cholesterol, reduce blood pressure and blood glucose levels, and therefore help to prevent chronic disease.
The C677T polymorphism in the MTHFR gene is related to several significant biochemical changes, as dyslipidemia, changes in serum levels of homocysteine, folic acid, vitamin B12 and some oxidative stress markers such as the CAT and MDA, leading to a high risk of the emergence of cardiovascular disease (CVD). A diet containing antioxidants, especially folate, is characterized by being beneficial for individuals with this genetic alteration to possess anti-inflammatory function, act on and oxidative stress play an important gene function. The aim of this study was to evaluate the influence of the C677T polymorphism of the MTHFR gene and the effect of a diet containing folate on oxidative stress, lipid profile and homocysteine levels in adult women are overweight or obese. This is an intervention study, double-blind, held in a city in northeastern Brazil. The study included 48 adult women (20-59 years old) with BMI of 26.19 kg / m² and 49.64 kg / m², in which we evaluated the CAT levels, MDA, lipid profile, folic acid, homocysteine and vitamin B12 addition genotyping for the C677T polymorphism in the MTHFR gene and the food consumption by the food recall 24 hours, being divided by randomization into two groups received daily for 8 weeks, 300g vegetables rich in folate containing 191 ug and 90 ug of this nutrient.
The primary aim of this study is to investigate the acute effect of the frequency and duration of breaks in sitting time on the metabolic risk factor profile.
The investigator is pilot testing the feasibility and impact of a low-cost intervention that uses existing gymnasiums, and therefore has the potential to be replicated across the United States. The intervention, PlayFit, is designed for adults aged 21-50. PlayFit has five key components, intended to overcome the major barriers to physical activity. First, it will assist people in finding others to play with, using the Pick-Up model of designating times to play and making those times known in the community. Second, it will overcome a lack of confidence in physical activity by including games of lower intensity for relatively unfit adults, then building up to moderate and vigorous games. Third, it will require team members of varying ages and genders to encourage intergenerational play. Fourth, it will use modified equipment (e.g., softer, lighter balls) and smaller game space to require less running, so that even relatively unfit people can feel confident participating. Fifth, it will be designed to be led by community volunteers, which will increase its disseminability. AIM - Understand the optimum design for PlayFit. To meet this aim, the investigators will come up with a list of games to play and pilot the games at a gymnasium. The investigators will observe the participants playing the games and have them complete a brief survey.
The purpose of this clinical study is to investigate the effect of drinking a sugar-sweetened beverage along with a meal on insulin concentrations and, glucose and lipid metabolism, in overweight and obese subjects, during a 10-hour visit.
It was proven in a previous clinical study that Glucosanol™ is effective and safe in reducing weight in the overweight and obese. The present study aims at expanding the data concerning the weight management effect of Glucosanol™ in overweight and moderately obese population.
The aim of the study is to examine if motivational interviewing can have a positive effect on weight loss over a 6 month period. By losing weight, the investigators assume the patients will have a positive effect on quality of life, and also that weight loss will help to regulate the factors that are present with polycystic ovary syndrom (PCOS); such as menstrual disorders and infertility. Participants will be randomly assigned to a treatment group and a control group. Both groups will be followed as normal with blood samples and other tests such as scans of the ovaries and measurement of height and weight at the beginning of the study and after six months. In addition, there will be a small hair sample taken from the neck at the first consultation and after 6 months. This is done to measure the stress hormone cortisol in the body over the duration of the experiment. The treatment group receive individual motivational interviews by a nurse every 14 days for a period of six months. After half a year, tests are repeated to see if there are significant differences between the groups.
This study aims to test the efficacy and feasibility of an acceptance, mindfulness and compassionate-based intervention for women with overweight and obesity without binge-eating disorder (Kg-Free). Kg-Free intervention comprises 10 weekly group sessions plus 2 booster fortnightly sessions (31/2months) 2h30 hours each, run in small groups at Coimbra's University Hospital. The main goal of Kg-Free intervention is to reduce weight self-stigma and unhealthy eating behaviours and promote quality-of-life by targeting weight-related experiential avoidance and self-criticism patterns. The intervention focuses on fostering a greater awareness and ability to be in contact, tolerate and accept all internal experiences (even the unwanted ones, such as craving for food, fatigue, stigma and shame), rather than trying to avoid, control or change them. Additionally, the intervention intents for participant's to develop a compassionate attitude towards themselves, especially during challenging times in order to decrease shame and self-criticism.
