background: koobideh kebab (barbequed minced meat) is one of the most popular iranian foods. reduction in the water holding capacity (whc) of meat during thermal processing makes the water and melted fat run out of the meat. the fat content of the final product depends on the proportion of the retained moisture and fat. meanwhile, high temperature and the presence of oxygen and iron in meat may...

dehulling is an important step in walnut processing that has considerable effect on the quality, chemical and microbial properties of walnuts. improving dehulling can increase the quality of the final product. this research studied the effect of genotype and hulling method on walnut properties. one experiment was performed as a factorial in a randomized complete block design with three replicat...

fat oxidation during exercise can be influenced by exercise intensity and duration, training status, diet and physical activity level. however, few studies have investigated the effect of time of day on the rate of fat oxidation during exercise. thus the present study was designed to investigate the effect of time of day on indexes of fat oxidation in active young women. for this purpose, 14 he...

the present study aimed to compare substrate oxidation and total energy expenditure during running with low and moderate intensity until exhaustion and one hour after exercise in obese male students. for this purpose, in a crossover study design, 11 male university students (mean age 20.45±1.69 years, bmi 31.26±1.3 kg/m2, body fat percentage 28.47±3.53 %) participated in this study. two exercis...

The aim of this study is to investigate the mechanism behind the slow increase in fat oxidation on a high-fat diet. Therefore, we determined 24-h substrate oxidation using respiration chambers and the rate of appearance and oxidation of plasma-derived fatty acids in seven healthy nonobese men (age 23 +/- 2 years, height 1.85 +/- 0.03 m, weight 70.4 +/- 2.3 kg, % body fat 13 +/- 1). Before testi...

In a retrospective study, we examined several determinants of basal fat oxidation in 720 healthy Caucasian volunteers. Adult men (n = 427) and women (n = 293) were characterized for resting energy expenditure and substrate oxidation by indirect calorimetry (after a 12-h overnight fast), peak O2 consumption by a treadmill test to exhaustion, body composition by hydrodensitometry, food intake fro...

Background: Obesity is characterized by impaired fat oxidation, and, therefore, the development of therapeutics designed to enhance fat oxidation for treating obesity is a growing focus in drug discovery. Evaluating such agents, however, is challenging in a clinical setting; requisite overnight fasting prior to a study visit increases whole body fat oxidation in lean, healthy subjects, making i...

BACKGROUND Obesity may be associated with a lowered use of fat as a fuel, which may contribute to the enlarged adipose tissue stores. AIM The aim of the present study was to study fatty acid use in the fasting state and in response to a high fat load in a large cohort of obese subjects (n = 701) and a lean reference group (n = 113). METHODS Subjects from eight European centers underwent a t...
