it seems that many people today are overweight. no one wants to carry around extra pounds, lout few people know how to slum down effectively. they look for miracle pills and magic cures. in the end, they fail and the pounds come back. but the most effective way of losing weight is actually very simple. it is a combination of a good diet and proper exercise. what makes it work is determination. it requires discipline and commitment to succeed. here is an example that proves the truth of these words.
my aunt had been trying to lose weight for years. she went on one diet after another, but none of them worked. she lost a lot of weight quickly only to have it come back. finally, she followed her doctor's advice and began to eat a simple, well-balanced diet. she ate lots of fruits and vegetables and avoided high-fat foods. in addition, she joined an exercise class. she worked out three times a week. at first, my aunt wasn't happy because the weight came off so slowly. but her classmates encouraged her to stick to it and eventually she reached her goal. best of all, she was able to stay at her ideal weight. that was because she had developed healthy new habits.
如何减肥
现在似乎有许多人的体重都过重。没有人会希望身上有多余的重量，但是很少人知道如何才能有效地瘦下来。他们会去寻找特效药，以及神奇的治疗法。最后不仅失败，而且反弹了。但是事实上，最有效的减肥方法非常简单。主要就是结合均衡的饮食，以及适当的运动。成功的关键就是要有决心。成功需要自制和投入。以下这个例子，可以证明这个方法是正确的。
我阿姨试图减肥已经好多年了。她一次又一次地节食，但是没有一次成功。她的体重会快速地下降，但没多久就又反弹了。最后，她听从医生的建议，开始吃简单、均衡的饮食。她吃大量的蔬果，并避免高脂肪的食物。除此之外，她还去参加运动课程。她一星期运动三次。起初，我阿姨并不是很开心，因为体重下降得很慢。但是她的同学们鼓励她坚持下去，最后她终于达到目标。最棒的是，她能够维持她的理想体重。因为她已经养成健康的新生活习惯。

英语演讲稿5分钟：有效减肥妙招
every day there seems to be a new diet or weight loss regime introduced. some of them work and others don't. here are some bizarre weight loss tricks that have actually been known to show positive results!
pop your multivitamins daily
a study that focused on a set of 96 obese women, who took a calcium supplement, multivitamin or placebo for 26 weeks, revealed that the group that took the vitamin had significantly less body fat. this shows that we tend to eat more when our body craves for certain nutrients. popping your multivitamin daily will help give your body what it needs. while it isn't enough to rely solely on popping a vitamin to lose weight, it may reduce the quantity of food you consume to feel full.
似乎每天都会有新的饮食法或减肥法出炉，有些会奏效但有些却没用。这里要为大家介绍几种看起来有点怪异但着实有效的减肥妙招。
每天摄入多种维生素
在一项针对96名肥胖女性的研究中，她们在26周内需要分别服用补钙产品，摄入多维他，或使用安慰剂。结果显示，那组摄入多维他的女性体内脂肪明显减少。这说明当身体渴求营养时会吃的更多，而每天摄入多维他有助于身体摄取所需要的营养。不过，仅仅摄入维他命是不足以减肥的，它会使你摄入的食量减少，招致饥饿感。
choose the right spot at the table
it is hard to resist al the yummy stuff at the dinner table when you dine out. try and select a seat at the end of the table because the center seats are where stuff like starters, sharing plates, bread or chips wind up.
check your e-mail
if you want access to a blast of information on nutrition and weight loss, a great place to begin would be your inbox. your email is probably filled with clever tips, tricks and hacks on how to get rid of excess weight, sent to you in the form of newsletters. a kaiser permanente study has revealed that people who read weekly wellness newsletters are more likely to eat fewer trans fats.
选对饭桌位置
外出吃饭时，很难抵制餐桌上美味食物的诱惑吧。选一个最靠边的座位，因为中间的位置会使你风卷残云般消灭食物，无论是开胃菜，共享的食物，还是面包薯条之类。
查看电子邮件
如果想置身于有关营养或减肥方面的漫天信息中，可以先去翻看收件箱。你的电子信箱可能塞满了一些充斥着聪明点子和妙招的简讯，它们会教你如何摆脱多余体重。美国健保机构凯撒医疗中心的一项研究显示，每周阅读健康简讯的人食用的反式脂肪会更少。
turn off your lights
an ohio state university study revealed that experiencing more darkness at night could make your body lighter. according to the study, mice that slept in total darkness were much less prone to obesity than those that slept in dim illumination or a bright light.
watch less tv
if we eat our meals when we are distracted, we tend to eat more, and therefore, consume more calories. the human body burns more calories while sleeping than watching tv.
关上灯
一项俄亥俄州立大学的研究显示，夜晚呆在更黑暗的地方会使体重减轻。根据研究，与在微亮或明亮的环境下睡觉的老鼠相比，在完全黑暗的环境下睡觉的老鼠患上肥胖症的几率更小。
少看电视
吃饭的时候分散注意力，往往会吃的更多，从而摄入更多的卡路里。一个人在睡觉时消耗的卡路里会比看电视的时候多。
avoid eating in your pajamas
according to research, the comfier you are while you eat, the more you tend to overeat. that doesn't mean that you should wear a three-piece suit while having your meals, but choose clothing that is a bit more form-fitting than pajamas, like yoga pants, leggings, tank tops etc. these clothes are comfortable, and also allow you to feel your waist expanding.
include more bacteria into your diet
our metabolism and appetite are both largely affected by bacteria. therefore, you should consider increasing the amount of probiotic-rich foods. this will allow you to lose weight without cutting calories.
不要穿着睡衣吃东西
根据调查，吃东西的时候穿的越舒服，就越容易吃的多。这并不让你在吃饭的时候穿着西服三件套，但可以选择穿比睡衣更紧身的衣服，如瑜伽裤，打底裤，背心等。这些衣服足够舒适，而且也可以让你觉察到腰围的增大。
多服用益生菌
我们的新陈代谢和食欲都很大程度上受到益生菌的影响。因此，需要多食用富含益生菌的食物。这样的话，不用减少卡路里也能减肥。
increase your spice intake
recent studies have revealed that consuming food that is high on spices like cayenne peppernot only increases your metabolism significantly, but also slows down the growth of fat cells.
drink more wine
it is said that drinking one or two glasses of wine a day makes you less susceptible to putting on weight. remember to keep it to not more than two glasses a day to reap the health benefits.
多吃辣的
最近的研究表明，摄入重辣食物如辣椒不仅大大促进了新陈代谢，而且可以减缓脂肪细胞的增长速度。
喝一点酒
据说，每天喝一到两杯的酒会不容易发胖。记住，为了保持健康，每天的饮酒量不可以超过两杯。
stop feeling guilty
go a little easy on yourself if you have cheated on your diet and had an unhealthy meal. research has revealed that dieters respond to stress like guilt about the meals they consume by further overeating.
eat off smaller plates
the smaller the plate, the less you will eat - it's that simple! one cornell university study set up an ice cream buffet for grad students and nutrition professors, who were given 17 or 34 ounce bowls and two or three ounce scoops. those people who had oversized bowls served themselves about 31% more. in addition to that, those people who had both big bowls and big scoops, served themselves 57% more than those with the small versions.
减少负罪感
如果你在节食时不小心多吃了或吃了不健康的东西，也别跟自己过不去。研究表明处于压力(如吃多了产生负罪感)下的节食者以后更容易暴饮暴食。
用小餐盘吃
餐盘越小，吃的会越少，就是这样简单!康奈尔大学为毕业生和营养学教授安排了一场冰淇淋自助餐，毕业生和教授分别拿到17盎司和34盎司大小的碗还有2盎司和3盎司大的勺子。那些使用超大碗的人会比其他人多摄入31%的冰淇淋。 而那些既有大碗又有大勺的人摄入冰淇淋的量，会比那些使用小碗小勺的人多57%。
eat bread last
a 20xx study entailed 100 obese people going on a diet of about 20% protein, 30% fat, and 50% carbohydrates. while the first group consumed starches throughout the day, the second group saved most of their carbohydrates for dinner. the second group lost more body fat, weight and abdominal inches than the first group after six months, and also reported feeling fuller during the day.
sleep in a colder room
it has been found that a chillier bedroom can not only improve your sleep, but also yourmetabolism. during the past few decades, the average indoor temperature has increased. in addition to that, we tend to set the temperature in our homes at a steady rate, preventing our body from experiencing too many drops in temperature. this also prevents it from regulating its own calorie-burning properties. when you sleep in a colder room, you are forcing your body to heat itself up for hours, and therefore burn more calories in the process.
check your allergy medication
weight gain is as common a complaint amongst allergy sufferers, as itchy eyes or a running nose. people who use antihistamines are known to be about five kilos heavier than those who don't. this could be because h1-type antihistamines may be blocking the histamines of the immune system, which play a vital role in breaking down fat. possible alternatives arecorticosteroids or allergy shots. but people who only find relief with antihistamines may have to exercise or adjust their diet to compensate.
最后吃面包
在20xx年的一项研究中，100名肥胖者分别摄入20%的蛋白质，30%的脂肪和50%的碳水化合物进行节食。第一组一天内消耗了全部淀粉，而第二组在晚餐时间仍留有大部分碳水化合物。六个月之后，第二组的人比第一组减少了更多的脂肪，重量和腰围，而且据说白天会有饱腹感。
在冷一点的屋子里睡觉
人们发现，在一间冰冷的屋子里睡觉不仅有助于提升你的睡眠质量，而且可以促进新陈答谢。在过去几十年间，室内的平均气温升高了。而且，我们往往会使家里维持稳定的温度，以免身体遭受大幅降温，但同时也阻止了自身调节卡路里的性能。当你在寒冷的房间睡觉时，你会不断的迫使自己捂热身体，因此，在这个过程中会燃烧更多的卡路里。
检查抗过敏药
过敏者如眼睛发痒，或鼻涕不停的人常会抱怨体重增加了。众所周知，使用抗组胺药品的人会比那些没有使用的人重个5公斤左右。这可能是因为h1型抗组织胺会阻止免疫系统组织胺的释放，而这些组织胺正是分解脂肪的重要因素。可行的替代药品为皮质类固醇或过敏疫苗，但那些只会使用抗组胺药缓解症状的人们也可以通过运动或调解饮食配合治疗。
第3篇 ted英语演讲稿：为什么节食减肥没效果？
简介：在美国，80%的女孩在她们10岁的时候便开始节食。神经学家sandra aamodt结合自己的亲身经历，讲述大脑是如何控制我们的身体的。节食减肥为何没效果?来听听她的说法吧!
three and a half years ago, i made one of the best decisions of my life. as my new year's resolution, i gave up dieting, stopped worrying about my weight, and learned to eat mindfully. now i eat whenever i'm hungry, and i've lost 10 pounds.
this was me at age 13, when i started my first diet. i look at that picture now, and i think, you did not need a diet, you needed a fashion consult. (laughter) but i thought i needed to lose weight, and when i gained it back, of course i blamed myself. and for the next three decades, i was on and off various diets. no matter what i tried, the weight i'd lost always came back. i'm sure many of you know the feeling.
as a neuroscientist, i wondered, why is this so hard? obviously, how much you weigh depends on how much you eat and how much energy you burn. what most people don't realize is that hunger and energy use are controlled by the brain, mostly without your awareness. your brain does a lot of its work behind the scenes, and that is a good thing, because your conscious mind -- how do we put this politely? -- it's easily distracted. it's good that you don't have to remember to breathe when you get caught up in a movie. you don't forget how to walk because you're thinking about what to have for dinner.
your brain also has its own sense of what you should weigh, no matter what you consciously believe. this is called your set point, but that's a misleading term, because it's actually a range of about 10 or 15 pounds. you can use lifestyle choices to move your weight up and down within that range, but it's much, much harder to stay outside of it. the hypothalamus, the part of the brain that regulates body weight, there are more than a dozen chemical signals in the brain that tell your body to gain weight, more than another dozen that tell your body to lose it, and the system works like a thermostat, responding to signals from the body by adjusting hunger, activity and metabolism, to keep your weight stable as conditions change. that's what a thermostat does, right? it keeps the temperature in your house the same as the weather changes outside. now you can try to change the temperature in your house by opening a window in the winter, but that's not going to change the setting on the thermostat, which will respond by kicking on the furnace to warm the place back up.
your brain works exactly the same way, responding to weight loss by using powerful tools to push your body back to what it considers normal. if you lose a lot of weight, your brain reacts as if you were starving, and whether you started out fat or thin, your brain's response is exactly the same. we would love to think that your brain could tell whether you need to lose weight or not, but it can't. if you do lose a lot of weight, you become hungry, and your muscles burn less energy. dr. rudy leibel of columbia university has found that people who have lost 10 percent of their body weight burn 250 to 400 calories less because their metabolism is suppressed. that's a lot of food. this means that a successful dieter must eat this much less forever than someone of the same weight who has always been thin.
from an evolutionary perspective, your body's resistance to weight loss makes sense. when food was scarce, our ancestors' survival depended on conserving energy, and regaining the weight when food was available would have protected them against the next shortage. over the course of human history, starvation has been a much bigger problem than overeating. this may explain a very sad fact: set points can go up, but they rarely go down. now, if your mother ever mentioned that life is not fair, this is the kind of thing she was talking about. (laughter) successful dieting doesn't lower your set point. even after you've kept the weight off for as long as seven years, your brain keeps trying to make you gain it back. if that weight loss had been due to a long famine, that would be a sensible response. in our modern world of drive-thru burgers, it's not working out so well for many of us. that difference between our ancestral past and our abundant present is the reason that dr. yoni freedhoff of the university of ottawa would like to take some of his patients back to a time when food was less available, and it's also the reason that changing the food environment is really going to be the most effective solution to obesity.
sadly, a temporary weight gain can become permanent. if you stay at a high weight for too long, probably a matter of years for most of us, your brain may decide that that's the new normal.
psychologists classify eaters into two groups, those who rely on their hunger and those who try to control their eating through willpower, like most dieters. let's call them intuitive eaters and controlled eaters. the interesting thing is that intuitive eaters are less likely to be overweight, and they spend less time thinking about food. controlled eaters are more vulnerable to overeating in response to advertising, super-sizing, and the all-you-can-eat buffet. and a small indulgence, like eating one scoop of ice cream, is more likely to lead to a food binge in controlled eaters. children are especially vulnerable to this cycle of dieting and then binging.
several long-term studies have shown that girls who diet in their early teenage years are three times more likely to become overweight five years later, even if they started at a normal weight, and all of these studies found that the same factors that predicted weight gain also predicted the development of eating disorders. the other factor, by the way, those of you who are parents, was being teased by family members about their weight. so don't do that. (laughter)
i left almost all my graphs at home, but i couldn't resist throwing in just this one, because i'm a geek, and that's how i roll. (laughter) this is a study that looked at the risk of death over a 14-year period based on four healthy habits: eating enough fruits and vegetables, exercise three times a week, not smoking, and drinking in moderation. let's start by looking at the normal weight people in the study. the height of the bars is the risk of death, and those zero, one, two, three, four numbers on the horizontal axis are the number of those healthy habits that a given person had. and as you'd expect, the healthier the lifestyle, the less likely people were to die during the study. now let's look at what happens in overweight people.
the ones that had no healthy habits had a higher risk of death. adding just one healthy habit pulls overweight people back into the normal range. for obese people with no healthy habits, the risk is very high, seven times higher than the healthiest groups in the study. but a healthy lifestyle helps obese people too. in fact, if you look only at the group with all four healthy habits, you can see that weight makes very little difference. you can take control of your health by taking control of your lifestyle, even if you can't lose weight and keep it off.
diets don't have very much reliability. five years after a diet, most people have regained the weight. forty percent of them have gained even more. if you think about this, the typical outcome of dieting is that you're more likely to gain weight in the long run than to lose it.
if i've convinced you that dieting might be a problem, the next question is, what do you do about it? and my answer, in a word, is mindfulness. i'm not saying you need to learn to meditate or take up yoga. i'm talking about mindful eating: learning to understand your body's signals so that you eat when you're hungry and stop when you're full, because a lot of weight gain boils down to eating when you're not hungry. how do you do it? give yourself permission to eat as much as you want, and then work on figuring out what makes your body feel good. sit down to regular meals without distractions. think about how your body feels when you start to eat and when you stop, and let your hunger decide when you should be done. it took about a year for me to learn this, but it's really been worth it. i am so much more relaxed around food than i have ever been in my life. i often don't think about it. i forget we have chocolate in the house. it's like aliens have taken over my brain. it's just completely different. i should say that this approach to eating probably won't make you lose weight unless you often eat when you're not hungry, but doctors don't know of any approach that makes significant weight loss in a lot of people, and that is why a lot of people are now focusing on preventing weight gain instead of promoting weight loss. let's face it: if diets worked, we'd all be thin already. (laughter)
why do we keep doing the same thing and expecting different results? diets may seem harmless, but they actually do a lot of collateral damage. at worst, they ruin lives: weight obsession leads to eating disorders, especially in young kids. in the u.s., we have 80 percent of 10-year-old girls say they've been on a diet. our daughters have learned to measure their worth by the wrong scale. even at its best, dieting is a waste of time and energy. it takes willpower which you could be using to help your kids with their homework or to finish that important work project, and because willpower is limited, any strategy that relies on its consistent application is pretty much guaranteed to eventually fail you when your attention moves on to something else.
let me leave you with one last thought. what if we told all those dieting girls that it's okay to eat when they're hungry? what if we taught them to work with their appetite instead of fearing it? i think most of them would be happier and healthier, and as adults, many of them would probably be thinner. i wish someone had told me that back when i was 13.
thanks.
