Cardiovascular Risk FactorInsulin Resistance6 moreThis platform will enable investigation the cardiovascular risk reduction and the increase in participant engagement in their heart-healthy goals, through the use of virtual care/telemedicine with a digital platform that connects them to their own doctors, nurses, and dietitians.
Glycemic and Hormone Responses After the Intake of Four Types of Bread.
HyperglycemiaInsulin SensitivityThe purposes of the present study are to determine the glycemic and insulinemic responses, the satiety rate and the postprandial plasma concentrations of free fatty acids, triglycerides and satiety hormones after the ingestion of four types of breads: handcrafted bread made with wheat organic flour; handcrafted bread with wheat flour of large-scale retail distribution; handcrafted bread with organic einkorn flour and a commercial wheat bread.
Study of Carrageenan's Effect on Insulin Resistance in Humans
Diabetes MellitusType 21 moreThe purpose of this study is to determine whether the ingestion of the common food additive carrageenan contributes to insulin resistance and thus to the pathogenesis of type 2 diabetes in humans.
Tea-beetroot-venous Occlusion Plethysmography
Insulin ResistanceObesityIn the present study, muscle perfusion will be studied before and after an oral glucose challenge following a fasting period.
Yoga Improves Aerobic Fitness, Glycemia and Mood State and Reduces Abdominal Obesity
ObesityInsulin ResistanceStretching and flexibility exercise such as yoga and functional resistance exercise are two forms of exercise that are growing in popularity. However, they have not been scientifically tested to demonstrate their ability to improve body composition, fitness, heart and metabolic health, and mood state in overweight/obese women. The investigators hypothesize that during an 11 week intervention, both forms of exercise will improve body composition, heart and metabolic health and mood state.
The Effect of Tea on Vascular Function and Insulin Sensitivity
Insulin ResistanceThe aim of this research is to explore changes in peripheral/cerebrovascular function and insulin sensitivity after a 7-day combination of physical activity reduction (-50% steps per day) and overfeeding (+50% kcal per day, comprising 65% fat) in healthy male volunteers, and examine whether daily intake of tea can prevent such changes.
The Effect of Cranberry Extract Supplementation on Cardiovascular Risk Factors in Obese, Insulin...
Insulin ResistanceAtherosclerosisThe purpose of this study is to determine the health benefits of cranberry extract in people who are at risk for diabetes and heart problems.
Glycemic Load, Metabolism & Obesity in Pregnancy
ObesityInsulin ResistanceThe purpose of the study is to determine if a low glycemic load diet reduces the gain of body fat and insulin resistance during the last half of pregnancy in obese women.
