美国学者对减体重问题发表了下列建议和意见书。其建议为:1.极度限止热量摄入的长期禁食是极不合理的,从医学角度讲,是危险的。2.极度限止热量摄入的长期禁食可导致大量的水、电解质、矿物质、储存糖元和其它去脂肪组织丢失,而脂肪丢失最少。3.适当减少热量的摄入(比平日每天摄入量少500—1000千卡);水、电解质、矿物质、其它去脂肪组织减少得较少;这样,引起营养不良的可能性也较小。4.大肌肉群的动力性运动有助于维持去脂肪组织,包括肌肉质量和骨密度,并可降低体重;借助于增加能量消耗减体重,则主要是减少脂肪组织。5.建议采用热量适量减少且营养合理的饮食,同时进行耐力性运动和改变进食习惯的综合措施来减体重。每周
American scholars made the following suggestions and submissions on weight reduction. The recommendations are: 1. Extremely limited long-term fasting caloric intake is extremely unreasonable, from a medical point of view, is dangerous. 2. Long-term fasting, which severely restricts caloric intake, can result in the loss of large amounts of water, electrolytes, minerals, stored glycogen and other de-adipose tissue with the least fat loss. 3. Properly reduce caloric intake (500-1000 kcal less daily than usual); water, electrolytes, minerals, and other fat-reducing tissues are less diminished; thus less likely to cause malnutrition . 4. The motility of large muscle groups helps maintain the body fat, including muscle mass and bone density, and can reduce body weight; by increasing energy expenditure to lose weight, the main is to reduce fat tissue. 5. It is recommended to use a moderate amount of calories reduced and nutritionally reasonable diet, while endurance exercise and change the eating habits of the integrated approach to reduce weight. weekly
