WEstlake N-of-1 Trials for MACroNUTrient Intake

2019-10-18 11:21:39 | BioPortfolio


This is a dietary intervention study in students and staff of Westlake University, which is designed to provide evidence in support of N-of-1 methods as an approach to advance personalized nutrition. The primary aim is using a series of N-of-1 trials to determine the impacts of a high fat, low carbohydrate diet (HF-LCD) on glucose metabolism and gut microbiota in subjects versus a low fat, high carbohydrate diet (LF-HCD) at both the individual and group level.


This study will employ a series of individual N-of-1 trials comparing a high fat, low carbohydrate diet (HF-LCD) to a low fat, high carbohydrate diet (LF-HCD). Participants will enter the study on a usual diet and will have a 6-day run in period for diet planning and baseline data collection before beginning their assigned diet treatment. Treatment periods will be assigned in blocks of two (e.g., AB) with the goal of each subject completing two balanced treatment blocks (e.g., ABAB) where treatment 'A' represents HF-LCD and treatment 'B' represents LF-HCD. Participants will be randomized to either the HF-LCD or the LF-HCD as their starting intervention and alternate between these two conditions for six 6-day treatment periods. There will be a wash-out period lasting for 6 days with normal diet between two interventions to eliminate previous intervention effects. Investigators will aggregate the results of the completed N-of-1 trials across all participants to estimate the group level impacts of HF-LCD compared to LF-HCD.

Effectiveness of a Low Carbohydrate Diet Versus a High Carbohydrate Diet in Promoting Weight Loss and Improved Health

This study will examine the effects of a low carbohydrate diet versus a high carbohydrate diet on weight loss.

Dietary Carbohydrate and Internal Body Fat

This is a 2-year randomized controlled trial to test the effect of dietary carbohydrates, both quality and quantity, on changes in internal body fat mass. Up to 250 women and men with obes...

Low Carbohydrate Diet vs. High Carbohydrate Diet in Type 1 Diabetes

The aim of the study is to investigate glycemic control during a low carbohydrate diet compared with during a high carbohydrate diet in adults with insulin pump treated type 1 diabetes.

Fatty Acid Biomarkers of Carbohydrate Intake

The overall aim is to investigate if circulating fatty acids and lipids are influenced by alterations in carbohydrate amount and quality.

The Safety and Efficacy of Low and High Carbohydrate Diets

This study will compare the safety and effectiveness of a low carbohydrate diet (Atkins Diet) with a high carbohydrate diet (conventional USDA diet).

Different effects of high-protein/low-carbohydrate versus standard hypocaloric diet on insulin resistance and lipid profile: role of rs16147 variant of neuropeptide Y.

Few studies have assessed the effect of the NPY gene rs16147 variant on metabolic response following a dietary intervention. We evaluated the effect of rs16147 on body weight and biochemical changes a...

High carbohydrate diet partially protects Nile tilapia (Oreochromis niloticus) from oxytetracycline-induced side effects.

Antibiotics used in global aquaculture production cause various side effects, which impair fish health. However, the use of dietary composition such as carbohydrate, which is one of the dominant compo...

A low-protein, high carbohydrate diet induces increase in serum adiponectin and preserves glucose homeostasis in rats.

The aim of this study was investigate the effects of a low-protein, high-carbohydrate (LPHC) diet introduced to rats soon after weaning. The animals were distributed in the following groups: LPHC45: f...

Sodium acetate alleviated high-carbohydrate induced intestinal inflammation by suppressing MAPK and NF-κB signaling pathways in Nile tilapia (Oreochromis niloticus).

With the development of aquaculture industry, high-carbohydrate diet is used to stimulate protein-sparing effect and reduce feed cost. However, fish utilize carbohydrates poorly in general, and instea...

Metabolomics Reveal Altered Postprandial Lipid Metabolism After a High-Carbohydrate Meal in Men at High Genetic Risk of Diabetes.

The transcription factor 7-like 2 (TCF7L2) gene confers one of the strongest genetic predispositions to type 2 diabetes, but diabetes development can be modified by diet.

Medical and Biotech [MESH] Definitions
