The Effect Of A Calorie Controlled Diet Containing Walnuts On Substrate Oxidation During 8-Hours In A Room Calorimeter, Linda C. Tapsell, Marijka Batterham, Sze Yen Tan, Eva M. Warensjo

Dr Marijka Batterham

Objective Dietary macronutrient proportions affect substrate utilization, but in practice people consume foods. We hypothesized that in overweight adults, a calorie controlled diet based on core foods and including walnuts may be advantageous in promoting greater use of fat stores. Methods This crossover study tested the effects of diet-related energy expenditure and fat oxidation in 16 overweight individuals over an 8-hour period. The 2 diets included breakfast and lunch meals during the measurement period and an evening meal the night before. They comprised core foods of bread/cereals, fruit, vegetables, milk/yogurt, and meat, and either walnuts (walnut diet) or olive oil …

Decreased Plasma Peptide Yy Accompanied By Elevated Peptide Yy And Y2 Receptor Binding Densities In The Medulla Oblongata Of Diet-Induced Obese Mice, Xu-Feng Huang, Chao Deng, Yean Tan, Gita Rahardjo

Xu-Feng Huang

It is well known that the peripheral peptide YY (PYY)-central neuropeptide Y (NPY) Y2 receptor axis plays an important role in promoting negative energy balance regulation. Both the hypothalamus and medulla oblongata express a high level of Y2 receptors; however, the functional role of this receptor in chronic high-fat diet-induced obesity has not been fully examined. Using quantitative autoradiography, this study measured binding densities of total [125I]PYY and Y2 receptors in the hypothalamus and medulla of chronic high-fat diet-induced obese (DIO), obese-resistant, and low-fat-fed mice. Plasma PYY was also measured using RIA after 22 wk of dietary intervention. The results …

Diet And Metabolic Syndrome: Where Does Resistant Starch Fit In?, Linda C. Tapsell

L. C. Tapsell

Metabolic syndrome is a term linking the clinical profiles of some of the world’s major health problems today: obesity, heart disease and diabetes. It is predicated on dietary patterns, and particularly on the delivery of fuel. The effects may be seen first in the development of abdominal obesity and insulin resistance leading to type 2 diabetes mellitus and coronary heart disease. This review examines the role resistant starch might play in the prevention and management of these conditions. Beginning with a definition of resistant starch, a critical review of the scientific literature is presented. Current knowledge suggests that resistant starch …
