Filter by:It has been observed that subjects with obesity and insulin resistance have higher concentrations of branched chain amino acids in plasma or serum. However, this association has been established under fasting conditions, so they only give information about a metabolic state and do not reflect the dynamics and flexibility of the metabolism of these amino acids in the absence or presence of insulin resistance. The main aim of this study is to compare the catabolism of branched chain amino acids and their keto acids in subjects with and without insulin resistance, after the infusion of an amino acid solution with high concentration of the branched chain amino acids, leucine, valine, and isoleucine. The results of this project will allow the investigators to understand the dynamics of the branched chain amino acids and their derivatives, and its relationship with insulin resistance, which could eventually be used to design nutritional strategies to treat insulin resistance and thus, delay the development of type 2 diabetes.
Over the years, increasing obesity prevalence represents an important threat to national and global public health. Many strategies studied for weight loss have reported that low-carbohydrate diets showed beneficial effects on weight loss for obese patients. However, individual weight losses have varied widely within low-carbohydrate diet groups due to the influence of gut microbiota, which was found in the previous clinical studies of our team (ChiCTR1800015156). Numerous animal studies and clinical trials have evaluated the impact of probiotics on glucose and lipid metabolism as well as weight-loss interventions. However, the effect of the different probiotic strains may play a different role in the same species. Therefore, our team isolated new strains (Lactobacillus reuteri PLBK1，GDMCC No: 60828、Lactobacillus reuteri PLBK2，GDMCC No: 60829、Lactobacillus gasseri PLBK3，GDMCC No: 60830、Lactobacillus acidophilus PLBK4，GDMCC No: 60831、Bifidobacterium lactis PLBK5，GDMCC No: 60832) from the oral cavity, feces or environment of the Chinese race in the previous study. The mixed solid beverage composed of these five strains has local characteristics and meets the requirements of the national standard for food additives, which has obtained the national food production license (SC10632028100205).In our previous animal experiments, the treatment of compound preparation of the above five strains improve insulin resistance and dyslipidemia effectively in obese mice induced by high-fat diet，which obtained significant weight loss . Nevertheless, clinical trials are needed to be carried out to confirm its clinical effect. Therefore, we aimed to conduct a randomized, double-blind, placebo-controlled prospective study on the basis of previous research. In order to evaluate the efficacy and safety, as well as the effect on glucose and lipid metabolism of low-carbohydrate diet combined with probiotics in obese participants, the study will last for 12 weeks. At the same time, Magnetic Resonance Imaging (MRI) will be used to clarify change in body fat distribution, which may provide more clinical evidence for the application of this program in the prevention and treatment of obesity in the future.
We propose to conduct a randomized 6-day isocaloric crossover feeding study in humans with prediabetes and obesity. We will study the effect of restricting the timing of caloric intake to earlier in the day (TRF) versus later in the day (usual feeding pattern, UFP) on glycemia and inflammation in an inpatient setting.
Background: Roux-en-Y gastric bypass (RYGB) is a surgery with low rate complications. However, it is not exempt from them, and 1-6% suffer complications such as postoperative bleeding. Many intraoperative techniques have been evaluated to reduce postoperative bleeding, like the oversewing or reinforcement of the staple line. This study aims to evaluate the rate of postoperative bleeding in the oversewing of the staple line of the gastric remnant group versus the stapling only group. Methods: This is a 2-center, case-control study. The investigators randomly selected two groups who underwent RYGB or OAGB: group A (n=225) with oversewing from 2019-2020 and group B (n=225) with stapling only between the period of 2017-2018; both groups with similar demographic characteristics.
Background: Metabolic Bariatric Surgery, including a surgery called vertical sleeve gastrectomy, is the most effective weight loss treatment for severe obesity. However, many adolescents who have this surgery still have obesity 1 year later or regain weight. Researchers want to see if a drug can help. Objective: To learn if liraglutide can help adolescents who still have obesity 1 year or more after vertical sleeve gastrectomy lose additional weight. Eligibility: Healthy adolescents ages 12-20.99 years who are 1-10 years post vertical sleeve gastrectomy and have a BMI of 30 kg/m2 or >=95th percentile for age and sex. Design: Participants will be screened with: Medical history Physical exam Questionnaires about their mood and feelings about their weight Blood and urine tests Nutrition counseling. They will keep a diet log. A test where they view and respond to pictures of food Wrist accelerometer set-up. They will wear an accelerometer (a device like a watch) on their wrist for 14 days. It will measure their physical activity. Some screening tests will be repeated during the study. Participants will have an oral glucose tolerance test. They will ingest a sweet liquid. Blood samples will be taken. Participants will take liraglutide daily for 16 weeks. They will learn how to inject it under their skin. Participants will have a body scan to measure muscle and fat. Participants will be invited to eat as much as they want at a buffet meal at NIH. How much food they eat will be calculated. They will assess their appetite and mood before and after the meal. Participation will last for 7 months. Participants will have 7 study visits....
This is a study of LY3437943 in participants who have obesity or are overweight. The main purpose is to learn more about how LY3437943 affects body weight loss. The study will last about 18 months and may include up to 18 visits.
The goal of this study is to assess the feasibility and acceptability of Teaching Obesity Treatment Options to Adult Learners (TOTAL intervention), which includes an educational video about obesity treatment options within VA in conjunction with three telemedicine motivational sessions to increase obesity treatment initiation. 10 participants will be recruited from the Madison VA Medical Center. Participation involves 3.5 hours of total time with study follow up to 18 months.
The present randomised controlled trial aimed to investigate the effectiveness of a clinical decision support system (CDSS) in assisting clinicians to apply nutritional care to breast cancer (BC) patients during the COVID-19 pandemic in Greece. Adult BC women (stages I-IIIA) who underwent mastectomy followed by hormone therapy were randomly assigned either to the Control group, receiving general nutritional advice, or the Intervention (or CDSS) group, in whom a personalised nutritional programme based on the Mediterranean diet together with physical activity guidelines were provided, all produced by CDSS. Medical and dietary history, anthropometrics, biochemical indices and quality of life characteristics were assessed both at baseline and at the end of the study (3 months).
This study is a single-arm behavioral weight loss intervention for emerging adult women with in-person assessments at 0 (baseline) and 4 months (post-treatment) in addition to EMA data collection regarding risk factors known to interfere with program engagement and weight loss in this high-risk population (e.g., sleep, psychological distress, life events).
Obesity is an ongoing major public health problem in most countries of the world for which the agrifood industry still remains criticized because of the abundant offer of high sugar-lipid-energy dense foods, particularly in the fast-food sector. The resulting societal pressure on the food industry probably explains in part the efforts that have been deployed to seek natural active ingredients and to develop functional foods favorably influencing energy balance. Capsaicin is a food non-nutrient constituent that was shown to decrease appetite sensations and subsequent energy intake. The measurement of heart rate variability revealed an association between the increase in sympathetic nervous system (SNS) activity and the satiating effects induced by capsaicin. This is concordant with the observation that pre-prandial intake of capsaicin, be it in capsules or diluted in tomato juice, increased satiety and reduced energy intake. The objective of this study is to evaluate the long effects of Capsimax on appetite sensations and energy expenditure under conditions of moderate energy restriction and to evaluate the long-term effects of Capsimax on energy intake and expenditure under conditions of moderate energy restriction.
