Filter by:Recent research shows that timing of nutritional intake and daily periods of fasting may have important health effects. In humans, limiting daily food intake to a narrow window (typically ~8 hours) can bring about some beneficial changes in blood concentrations of fats, sugar and the hormone insulin. It is thought that many of these changes are due to the prolonged daily fasting periods and humans will have regularly experienced prolonged fasting periods throughout evolution. In the modern era, food access is widely available and it is not uncommon for the time between breakfast and a late night snack to exceed 14 hours. We have recently shown that extending habitual daily periods of fasting to 16 hours per day also improves the ability of skeletal muscle to take up amino acids, the building blocks of protein. We are interested in studying whether a single episode of prolonged overnight fast (~16 hours), when compared to a normal overnight fast of 10 hours, is sufficient to stimulate skeletal muscle protein synthesis in response to dietary protein ingestion in healthy humans.
This is a randomized clinical trial to assess the feasibility and efficacy of time-restricted eating (TRE) to improve glucose regulation and cardiovascular health of participants with type 2 diabetes mellitus (T2DM). Participants will be randomized into 2 groups: 1) standard of care (SOC), in which they will continue to follow their physician's treatment plan, or 2) SOC and TRE (8-10 hours eating window).
There is increasing evidence of the effects of the time-restricted diet model based on the daily intake of energy within a period of 8-12 hours on body weight control and metabolic parameters. There is no study on the potential effects of this nutritional model, which is thought to be an effective strategy in struggling with metabolic syndrome, on individuals' eating behavior and impulsivity levels. This study, which aims to evaluate the effects of time- restricted diet strategy on food intake, eating attitude and behavior and impulsivity level in adults, is a mixed method, randomized controlled intervention study. Thirty adult individuals between the ages of 18-65 will be included in this study, which will be carried out between 31.05.2021-31.12.2021 in Istinye University. Participants will be divided into 2 groups: the intervention group (n = 15) will apply a time-restricted nutrition model for 4 weeks, and no intervention will be applied to the control group (n = 15). Participants' food intake before and after the intervention period will be evaluated with a 3-day food intake record, their eating attitudes will be evaluated with the Eating Attitude Test (EAT-26), their impulsivity levels will be evaluated with the Barratt Impulsiveness Scale-Short Form (BIS-11-SF) and Go / NoGo test, and their eating behaviors will be evaluated with the Three Factor Eating Questionnaire (TFEQ-R21). At the end of the research, all individuals in the intervention group will be interviewed in depth and their experiences regarding the process will be recorded. IBM SPSS 22 program will be used in the analysis of all quantitative data, and the MAXQDA-12 program will be used in the analysis of qualitative data. The data obtained from this research will clear up the applicability of the time- restricted diet model and its effects on eating behaviors of adults.
The overarching goal of this project is to assess whether a controlled short-term Time restricted feeding (TRF) intervention leads to metabolic benefits, improves recovery after vascular surgery and that TRF is safe. Participants suffering from intermittent claudication (Fontaine stage II peripheral artery disease, PAD) will be randomly assigned to a 2-week TRF or active control dietary advices before open surgical revascularization. Prior to the surgery, the investigators will assess the eating patterns of participants with an innovative smartphone application ('app') which is less intrusive and more reliable than food diaries/questionnaires to assess eating behavior and patterns. In the second part of the study, the investigators will investigate whether a short term TRF intervention improves surgical recovery, in the short-term (1 month, primary endpoint) and long-term (optional, up to 1 year), as part of the routine clinical follow-up. This proposal builds on established expertise in the biology of dietary intervention, surgery, and study of eating patterns in human.
The purpose of this study is to test whether eating earlier in the day and/or timed light therapy can improve blood sugar in people with type 2 diabetes. This study will also test whether these treatments improve other aspects of health, including the circadian (biological) clock, sleep, weight, body composition, cardiovascular health, quality of life, and mood.
Background: Time-restricted feeding can improve insulin sensitivity, and increase fat oxidation in people with prediabetes independent of weight loss. It may also help people to lose weight. However, it has not been tested in people with type 2 diabetes. Plan of investigation: Participants meeting the eligibility criteria will be randomized to the TRF arm or the continuous eating arm. Both arms with be given a prescribed dietary plan to help them lose 5% of body weight. In the TRF they will permitted to eat between midday and 6pm. In the continuous eating arm they will be allowed to eat between 8am and 11pm. Participants will attend the nutrition clinic every two weeks to be weighed and be given personalized support to help them follow their assigned diet. Prior to starting the diets outcome measures will be taken: Glycaemia will be measured by a glucose tolerance test, and 7-day continuous glucose monitoring. HbA1c will be taken from fasting blood sample. In addition, the fasting sample will be taken for measurement of insulin, lipid profile and inflammatory markers. We will also use questionnaires to assess quality of life, a 3-day food diary to assess compliance to diet especially meal timings. Capillary ketones will also be used to assess whether compliance to the assigned fasting period. Outcome measures will also be taken during 7 days of the second month, and then the final seven days of the last month on the diet. The primary outcome is HbA1c.
We evaluated the effects of Time-Restricted Feeding (TRF) regimen on Impaired Glucose Regulation (IGR) in comparison with overweight/obese patients receiving standard of care over 12 months.
