法国博士老头改良的单一蛋白饮食法。在这之前,有单一脂肪饮食、单一糖类饮食等等,反正褒贬不一。
个人不是很赞同这种单一饮食法,尤其是单一蛋白饮食法,顾虑如下:
1、过量蛋白质分解导致尿酸过高,增加对肾脏的工作负荷?
2、纯蛋白饮食,导致营养素不均衡问题,维生素、矿物质等严重短缺?
3、单一蛋白饮食,对某些人会有脂肪和糖类缺失引起的风险?
附上朋友和她国外导师讨论的原文:
1. Dr. Dukan justified his diet in this way: he emphasizes a lot about the benefit of pure protein diet. For example, it addresses the hardest part of weight loss—hunger. The fault of traditional energy control diet is that usually the dieters are not satisfied with the reduced amount of food allowed. They have great appetite, which is the reason why they are obese. Reducing food amount is challenging the nature of this group of people and is too demanding for them to keep eating an unsatisfying amount of food for their whole life. That’s why this kind of energy control diets always fail.
2. Dr. Dukan also mentioned that in this diet, the dieters do not need to worry about energy calculation or the side effect of common weight loss diet such as the loss of muscle and loosened skin. He spent some time talking about the harm and faults of high fat and high cho diets regarding health. To be fair, he also mentioned the shortages of pure protein diet—expensive; the wastage produced during protein digestion, such as urine acids. But then he explained that protein food is much affordable nowadays and that urine acids can be eliminated as long as you drink sufficient water (1.5L) ;constipation—can be tackled by eating oat bran. All in all, there are solutions for all the problems of the dukan diet.
3. But, obviously Dr Dukan did not properly explain the nutritional deficiency of this diet, such as the lack of some vitamins and minerals in the pure protein stage. And he did not even mention the health risk of a diet without cho or fat. I do know some people who have tried this diet before. They did lose some weight, but some of them reported that they just didn’t feel right in the pure protein stage. Probably it’s due to the withdrawal effect of carbohydrate—fatigue and too exhausted to exercise. And, another dietitian said that some of his clients stuck in the first stage because they were in fear of putting on weight once they moved on to the next stage.
4. Dr Dukan hided the fact that too much protein puts much burden on one’s kidney and can be converted to fat stored in body as well. Surprisingly he encouraged caffeine, artificial sweeteners, and supplements instead of real food. Considering the long term effects on health, this diet is unsustainable at all.
5. What im thinking is that: though pure protein diet may help with weight lost, we as dietitians should never recommend it to clients for the sake of their health. But what if trying pure protein diet for only 1 day per week? It should not be risky. I hope there are some research on the topic that weather 1 pure protein day per week would help with weight loss without health risk. But I believe this kind of research would never get ethical approval.

对于本书,我也做了点摘要,仅供参考:
1、糖分而不是脂肪摄入过多才造成肥胖的,血糖可以直接由胰岛素转化成脂肪。
2、胖子之所以会胖,绝对不是偶然,他们贪吃及对食欲的放纵,背后隐藏着借由吃来犒赏自我的需要。这样的需要不仅无法抗拒,而且是由来已久、根植人心的生存之道。如果超重人群真能自觉坚持平衡饮食,就根本不会遭遇体重问题。
3、想要瘦下来的肥胖者需要立竿见影,一开始就瘦很多的饮食法,这样才能加强、维持他们的动力。首先要减少或去除摄取富含糖类()、脂肪的食物。
4、四个阶段:速效期,纯蛋白饮食(完全不能吃糖类食物,植物性蛋白包含糖类,因此不能用,豆制品可以),平均五天,喝大量的水;
缓效期,蛋白质、蔬菜交替,减1公斤需要约1周;
巩固期,时间为瘦下来的公斤数乘以十,每星期一次纯蛋白餐;
稳定期,每周四一次纯蛋白饮食,持续一辈子。
5、太咸的食物会把水分锁在组织内。
6、纯蛋白:瘦肉、动物肝脏舌头、鱼类、海鲜类、家禽、豆制品、蛋、脱脂乳制品、魔芋;合成添加物阿斯巴甜代糖
7、按提供能量由少到多区分,水果优先考虑富含果胶的苹果,然后是西瓜、奇异果、桃子等。
8、利用低温控制体重,为抵御寒冷身体需用掉更多能量,穿的少、洗澡用水温低点的、食用冷食、冷饮、吸吮冰块等等。
9、三种加强的极简活动:拒绝电梯、尽可能常常站立、坚持步行。
10、 减重停滞期破解方法:连续4天纯蛋白饮食、尽可能减少盐分摄入、每天2升水其中应含有少量矿物质、尽可能提早睡觉时间、服用吻合职务利尿剂以消除体内多余水分、坚持步行60分钟或其他等同功效运动。
11、 人们过度饮食是因为需要某些实在的东西来填补日常生活中所缺失的快乐,而她本人可能都没有意识到这一点。或者,他希望借此来消除某种痛苦或减轻过重的生活负担与压力。减重的困难在于,您在此过程中不仅会丧失利用食物填补空虚的机会,甚至由于无法随心畅享喜爱的食物,造成愉悦感的进一步缺失,令您感到沮丧和挫败。
12、卡路里瘦身法完全基于理性的数字,而忽略了减重者的情感、情绪、喜悦,以及他们寻找感官满足的迫切需求。卡路里饮食若不能与严格、有效的监控相结合,就会逐渐走向失败。
13、减肥过程中的咨询,其实他们中的绝大多数人都知道问题的答案究竟是什么,他们真正需要的,就是提问以及被倾听,以此获得他们赖以支持的外在意志力。
最后,再次强调一下,单一蛋白饮食法不可取。
减肥,其实是意志力和执行力的问题,而不是方法。
