不行！节食很容易反弹，而且对身体不好。
节食的危害：
过度节食的主要危害是产生神经性厌食症。用极端的方法来控制自己的饮食，或者吃自己的零食，水果，或一天吃很少的食物，久而久之，必然导致大脑的饥饿和饱足感的神经中枢紊乱，吃多了要少胃口越来越低，直至食物的厌恶，最后一次见到吃的一种神经反应，恶心，呕吐食物，导致神经性厌食症。
其次是闭经。因为求瘦心切饮食治疗肥胖青少年女性倾向于扭转，以便在一段相对短的时间内，重量通常会迅速下降。医学资料表明，在一年之内，超过5公斤的体重突然减轻或减少年轻女性的10％，一直月经规律，常常突然变化，直到绝经期。这是因为人的大脑具有较低的丘脑，下丘脑，不仅有饥饿感和饱感中枢的感觉，而且还分泌一种叫促黄体激素释放激素，用来刺激垂体促黄体生成LH和卵泡刺激分泌激素，这两种激素刺激睾丸或卵巢发育的作用，为月经来潮和精子，卵子生成显著。由于过度节食，皮质功能减退时，黄体生成素和卵泡刺激素的分泌，雌激素和孕激素的卵巢分泌也减少，从而导致闭经。较长时间闭经，治愈的几率越低，对女性的健康危害后果会更严重正确的应该是控制食量。脂肪多，其实都是运动量与吸收的热量不平衡。
正确的减肥方法：
1、慢跑，每天慢跑40分钟左右，不需要你跑多快，慢慢跑就是，这是消耗热量的一种最轻松最有效的方式，而且对身体健康也很有用。
2、做仰卧起坐，每天30个，也可以根据个人情况增加。
这两种方法应该是最简单也最有效的了。
3.早饭尽量少吃脂肪多的食物:
4.每顿饭吃完后,不要急着坐下,先站最少15分钟(多了更好!)
5.在睡觉前两个小时不要吃任何东西哦!
6.两餐之间不要进食!
一般人晚饭不吃扛不住,即便忍着 也很难长期坚持.
所以,建议改变一下饮食习惯:早饭吃点营养价值高的东西,不要太多,够用,能坚持到吃中饭就可以了,早饭与中饭之间不要吃任何东西.中饭要花样多些,吃饱点,要吃肉(耐消化),豆腐,蔬菜,主食要吃够量.之后就可以不再进食了,如果顶不住,晚上喝点酸奶,吃点水果或生的蔬菜,如黄瓜 西红柿 生菜 之类,不要吃炒菜.(西红柿 黄瓜不要同时吃,会降低两种蔬菜的营养价值).
睡前3小时内什么也别吃,要吃就早点.
我同学家,晚上不开火,饿了就是水果 酸奶,其他两顿正常吃.8个月减了20多斤,高血压 脂肪肝 血脂高 都好了.
我中午吃很多,晚上不饿就基本上不吃了.如果晚饭时感觉肚子已经有点空了,有可能坚持不到睡觉,就少吃点,保证睡前不饿就行.我感觉一直很好,精力充沛,50多了,百米还能跑16秒多.不信吧?是真的.
祝你健康,美丽(帅气)!
一定能减肥，因为一顿饭通常是吃不了一天的食物的，所以会出现营养缺乏的状况，比如脸色难看，皮肤松弛，脱发、失眠、经期紊乱等一系列问题就会接踵而至，而且特别容易反弹。
