High-fat diet (HFD) induces obesity. This study examined the effects of Shiitake mushroom on the prevention of alterations of plasma lipid profiles, fat deposition, energy efficiency, and body fat index induced by HFD. Rats were given a low, medium, and high (7, 20, 60 g/kg = LD-M, MD-M, HD-M) Shiitake mushroom powder in their high-fat (50% in kcal) diets for 6 weeks. The results showed that the rats on the HD-M diet had the lowest body weight gain compared to MD-M and LD-M groups (P < 0.05). The total fat deposition was significantly lower (-35%, P < 0.05) in rats fed an HD-M diet than that of HFD group. Interestingly, plasma triacylglycerol (TAG) level was significantly lower (-55%, P < 0.05) in rats on HD-M than HFD. This study also revealed the existence of negative correlations between the amount of Shiitake mushroom supplementation and body weight gain, plasma TAG, and total fat masses.

Increased Intake Of Dietary Polyunsaturated Fat Does Not Promote Whole Body Or Preferential Abdominal Fat Mass Loss In Overweight Adults, Sze-Yen Tan, Marijka Batterham, Linda Tapsell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Objective: There is evidence that increasing the proportion of polyunsaturated fatty acids (PUFA) in a diet can enhance the rate of fat oxidation acutely. Higher PUFA in a diet has also been associated with greater abdominal fat loss in longer term studies. This study aimed to investigate if higher PUFA intake would result in greater fat mass loss over a 12-week period, mainly from the abdominal region.

Methods: Data at the 12-week time point from two weight loss studies, both comparing high PUFA versus low PUFA diets was, accessed for 141 overweight subjects from the same area. Specifically, data on …

Saturated- And N-6 Polyunsaturated-Fat Diets Each Induce Ceramide Accumulation In Mouse Skeletal Muscle: Reversal And Improvement Of Glucose Tolerance By Lipid Metabolism Inhibitors, G Frangioudakis, J Garrard, K Raddatz, J L. Nadler, Todd W. Mitchell, Carsten Schmitz-Peiffer

Faculty of Health and Behavioural Sciences - Papers (Archive)

Lipid-induced insulin resistance is associated with intracellular accumulation of inhibitory intermediates depending on the prevalent fatty acid (FA) species. In cultured myotubes, ceramide and phosphatidic acid (PA) mediate the effects of the saturated FA palmitate and the unsaturated FA linoleate, respectively. We hypothesized that myriocin (MYR), an inhibitor of de novo ceramide synthesis, would protect against glucose intolerance in saturated fat-fed mice, while lisofylline (LSF), a functional inhibitor of PA synthesis, would protect unsaturated fat-fed mice. Mice were fed diets enriched in saturated fat, n-6 polyunsaturated fat, or chow for 6 wk. Saline, LSF (25 mg/kg · d), or MYR …

The aim of this study was to examine the effect of endurance training on skeletal muscle phospholipid molecular species from high-fat fed rats. Twelve female Sprague- Dawley rats were fed a high-fat diet (78.1% energy). The rats were randomly divided into two groups, a sedentary control group and a trained group (125 min of treadmill running at 8 m/min, 4 days/wk for 4 weeks). Forty-eight hours after their last training bout phospholipids were extracted from the red and white vastus lateralis and analyzed by electrospray-ionization mass spectrometry. Exercise training was associated with significant alterations in the relative abundance of a …

Short Term Effects Of Energy Restriction And Dietary Fat Sub-Type On Weight Loss And Disease Risk Factors, Linda C. Tapsell, Marijka Batterham, Xu-Feng Huang, Sze Yen Tan, Grigorijs Teuss, Karen E. Charlton, Jane E. O'Shea, Eva M. Warensjo

Faculty of Health and Behavioural Sciences - Papers (Archive)

Background and aims: Decreasing energy intake relative to energy expenditure is the indisputable tenet of weight loss. In addition to caloric restriction modification of the type of dietary fat may provide further benefits. The aim of the present study was to examine the effect of energy restriction alone and with dietary fat modification on weight loss and adiposity, as well as on risk factors for obesity related disease. Methods and results: One-hundred and fifty overweight men and women were randomized into a 3 month controlled trial with four low fat (30% energy) dietary arms: (1) isocaloric (LF); (2) isocaloric with …

Fat Flat Frail Feet: How Does Obesity Affect The Older Foot, Julie R. Steele, Karen J. Mickle, Bridget J. Munro

Faculty of Health and Behavioural Sciences - Papers (Archive)

The prevalence of obesity is rising throughout the world at an alarming rate, and the elderly are no exception with 15% of men and 28% of women aged over 60 years considered to be obese [1]. Overweight and obesity have been shown to negatively affect foot structure and function in both children [2] and adults [3]. These structural changes appear to be associated with increased foot discomfort whereby overweight children have been found to report foot pain significantly more often than their leaner counterparts [4]. As feet are our base of support during most weight-bearing activities, it is postulated that …

The effects of dietary saturated fatty acids and polyunsaturated fatty acids (PUFA) of the n-3 and n-6 series on weight gain, body composition and substrate oxidation were investigated in broiler chickens. At 3 weeks of age three groups of chickens (n 30; ten birds per group) were fed the fat-enriched experimental diets for 5 weeks. These diets were isonitrogenous, isoenergetic and contained 208 g protein/kg and 80 g edible tallow, fish oil or sunflower oil/kg; the dietary fatty acid profiles were thus dominated by saturated fatty acids, n-3 PUFA or n-6 PUFA respectively. Resting RQ …

Fat In Food And The Obesity Epidemic, Linda C. Tapsell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Dietary fat is strongly implicated in the development of insulin resistance and obesity, both major public health problems today. While the amount of dietary fat is relevant, the type of fat is important in fuel utilisation, storage and appetite regulatory mechanisms. Human calorimetry research confirms the importance of dietary fat in energy balance, but more work needs to be done to uncover the impact of type of dietary fat in weight control. Population and intervention research confirm the importance of fat in dietary interventions, bearing in mind the contribution of physical activity to energy balance. The food industry has an …
