概括
增加能量流可以改善肥胖青少年的食欲控制. 较高的能量流量状态减少了饥饿和吃饭的欲望,有助于食欲调节.
科学领域:
- 代谢和内分泌学
- 儿童肥胖研究儿童肥胖研究
- 调节食欲 研究 研究 研究 研究
背景情况:
- 有证据表明,高能量流 (HEF) 可以改善成人和瘦身儿童的食欲控制.
- 在肥胖的青少年中,HEF对食欲调节的影响仍未得到充分研究.
研究的目的:
- 研究不同能量流量水平对肥胖青少年短期食欲控制的影响.
- 为了比较低能量流 (LEF),中等能量流 (MEF) 和HEF条件下的食欲反应.
主要方法:
- 16名患有肥胖的青少年 (12-16岁) 完成了随机的LEF,MEF (+250卡路里) 和HEF (+500卡路里) 条件.
- 通过能量摄入和自行车运动 (65% VO2峰值) 来操纵能量流.
- 评估ad libitum能量摄入量,宏观营养素摄入量,相对能量摄入量,主观食欲和食物奖励.
主要成果:
- 与HEF相比,LEF中晚餐的ad libitum能量摄入量显著增加.
- 在LEF,相对能量摄入量高于MEF和HEF.
- HEF条件导致饥饿,食欲和未来食物消费的总AUC降低,这表明食欲控制得到改善.
结论:
- 增加能量流可以提高肥胖青少年的短期食欲控制.
- 较高的能量流状态似乎减少了饥饿和吃饭的欲望.
- 研究结果表明,潜在的饮食和运动策略可以在这个人群中控制食欲.

Regulation of Food Intake
280
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Energy Balance
449
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Obesity
534
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Binge Eating Disorders
145
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Metabolic States of the Body: Fasting and Starvation
1.5K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...
