Effect of a Carbohydrate-rich Diet in Healthy Subjects

2019-09-18 03:27:39 | BioPortfolio


The present research protocol will analyze whether a short-term modification (one week) of dietary habits would have an impact on the postprandial metabolism of dietary fatty acids and on their uptake by non-adipose tissues, in healthy subjects.

Each subject will participate in two protocols randomly determined and separated by a period of one month: a 7-day isocaloric diet (Protocol A) and a 7-day carbohydrate-rich diet containing +50% of the subject's energy needs. (Protocol B).

At the end of each diet, the subject will go through a postprandial metabolic study of 8 hours where different parameters will be measured thanks to PET imaging and perfusions of stables isotopes.

The Effects of Formula Diet on Body Weight, Body Composition, and Biomarkers for Disease Compared to a Standard Diet

It is hypothesized that the use of a partial supplement diet, which includes the use of meal replacements, will result in significantly greater weight loss after three and six months compa...

Effect of Previous Diet

Meal ingestion induces digestive responses associated to homeostatic and hedonic sensations. The responses to meal ingestion are modulated by conditioning factors. Single-centre, cross-ove...

Effect of Meal Frequency and Timing on Insulin Dose and Clock Gene in Type 2 Diabetic Patients

This study is undertaken to explore in patients with uncontrolled T2D treated with insulin, whether a diet with large breakfast and lunch with small dinner (Bdiet) will enhance CG expressi...

Liquid Meal Replacements in Conjunction With Lifestyle Intervention in Overweight Adolescents

In this 3-month pilot study, we will introduce to 40 adolescents "at risk for overweight" (i.e., a BMI/age >85th percentile) a structured meal plan consisting of meal replacements, fruits,...

A Low-residue Diet vs Clear Liquid Diet as a Bowel Colonoscopy Preparation With Polyethylene Glycol (PEG)

This was a randomized, endoscopists' blinded comparison of bowel colonoscopy cleansing and tolerability of a prespecified low-residue diet compared with a clear liquid diet and Polyethylen...

Podoplanin and PROX1 Expression in Hypercaloric Diet-induced Pancreatic Injuries.

The role of podoplanin (PDPN) and homebox prospero gene 1 (PROX1) in early stages of pancreatic islet changes induced by hypercaloric diet is unclear. The aim of this study was to study PDPN and PROX1...

Glucose and Lipid Homeostasis and Inflammation in Humans Following an Isocaloric Ketogenic Diet.

The objective of this study was to measure changes in glucose, lipid, and inflammation parameters after transitioning from a baseline diet (BD) to an isocaloric ketogenic diet (KD).

Effect of Hevea brasiliensis seed meal or Euphorbia heterophylla seed supplemented diets on performance, physicochemical and sensory properties of eggs, and egg yolk fatty acid profile in guinea fowl (Numida meleagris).

A total of 144 French selected breed (Galor) female guinea fowl (GF) of 42 wk of age were enrolled for a feeding trial of 15, 30, and 45 D duration. The birds were randomly assigned to 18 cages, each ...

Continuous feeding of a combined high-fat and high-sucrose diet, rather than an individual high-fat or high-sucrose diet, rapidly enhances the glucagon-like peptide-1 secretory response to meal ingestion in diet-induced obese rats.

Glucagon-like peptide-1 (GLP-1) is secreted by enteroendocrine L-cells in response to nutrient ingestion. To date, GLP-1 secretion in diet-induced obesity is not well characterized. We aimed to examin...

Changes in masseter muscle fibers by liquid diet rearing in rabbits and recovery by chewing of solid diet.

To investigate the effects of liquid diet on the development of masseter muscle fibers and whether the changes in the masseter muscle can be recovered by chewing of solid diet.

Medical and Biotech [MESH] Definitions

A diet that contains limited amounts of CARBOHYDRATES. This is in distinction to a regular DIET.

Regular course of eating and drinking adopted by a person or animal. This does not include DIET THERAPY, a specific diet prescribed in the treatment of a disease.

A diet that contains limited amounts of fat with less than 30% of calories from all fats and less than 10% from saturated fat. Such a diet is used in control of HYPERLIPIDEMIAS. (From Bondy et al, Metabolic Control and Disease, 8th ed, pp468-70; Dorland, 27th ed)

A diet which is devoid of GLUTENS from WHEAT; BARLEY; RYE; and other wheat-related varieties. The diet is designed to reduce exposure to those proteins in gluten that trigger INFLAMMATION of the small intestinal mucosa in patients with CELIAC DISEASE.

A course of food intake that is high in FATS and low in CARBOHYDRATES. This diet provides sufficient PROTEINS for growth but insufficient amount of carbohydrates for the energy needs of the body. A ketogenic diet generates 80-90% of caloric requirements from fats and the remainder from proteins.
