Obesity easily fall to eat the five types of food

By the fall, people lose weight to the good life, although many people are dieting to lose weight as the preferred method, but often have little effect. That's why we eat are "slimming food" did not succeed in the end not only lose weight, but also a fertility? » Reason for this is that some seemingly supermarket food diet can actually lose weight is the biggest nemesis. Let us - that they "attempted" to it.

1. Excessive protein

Protein is also a kind of material and energy production, if eating more, food into the energy requirements than the human body, or store fat. The multi-protein food for meat, eggs, milk, soybeans category, food, vegetables and fruit also have a small amount of protein.

Containing protein-rich food (meat, eggs, milk, soybeans) are high in fat, they eat more fatty food will eat more with. Protein metabolite excretion from the kidney, eating more protein will add to the burden of kidney, a metabolic product of more than kidney excretion capacity will lead to "azotemia" harmful to the body.


2. Eat "oil" too many


Containing protein-rich food (meat, eggs, milk, soybeans) are high in fat, they eat more fatty food will eat more with. Protein metabolite excretion from the kidney, eating more protein will add to the burden of kidney, a metabolic product of more than kidney excretion capacity will lead to "azotemia" harmful to the body. Fat diet is the Taiji, in order to prevent obesity, and less involvement to the high fat content of food. Eliminate fatty foods that white is less oil, oil by the medical terminology as "fat", the oil is vegetable oil and animal fat, vegetable oil is pure fat, fat of the major components of fat, fat also found in meat, offal, Eggs, milk, soy products and even food, certain vegetables, (such as: soybean) have a certain amount of fat.

3. Eat more carbohydrates

1 g carbohydrate, or 1 g protein produced only 4 kilocalories, 1 g fat Nengchan 9 kilocalories, so eat more fat is equivalent to eat a lot of carbohydrates or protein. Vegetable oil than the equivalent weight of fat contained more fat, because fat in addition to fat, also contains water, protein, fiber. Some people said: "I do not Chi Feirou, eating Suyou, obesity can be avoided." Essentially is a misunderstanding, melon seeds, peanuts, walnuts, pine nuts, hazelnut, summer fruits such as nuts, food ingredients almost half of the fat . Some people love to eat these snacks also mean that a lot of fat. Some of restaurant, cooking oil growing, cooking Chuguo in order to look good when throwing to the oil, all kinds of "boiled fish", "Shui Zhurou", "Xiang Laxie" is essentially " Cooking oil, "eating into the oil can not be excessive.

Carbohydrate digestion by the gut into single sugar (glucose, fructose and galactose) was Xishouruxue, part of the organization have a direct use of energy for human needs, some stored in cells, if there are extra-sugar, Will become fat stored in the body of. - Carbohydrate food grain, beans, milk, fruit, nuts and vegetables.

Low living standards of the time before Fushi poor, ordinary people Meidun Fan April 2 Banjin staple food to eat is very common, now living standards improve, Fusi Well, staple food to eat on April 2 Banjin also on the excess. Some people eat too much fruit, especially to eat high-sugar content of fruit (bananas, persimmons, grapes, litchi), has increased the intake of carbohydrates.


4. + Dessert snacks

Some people like to eat snacks, drink sweet beverages, in particular, feel life is dull or watching television when the number of snacks eaten. Snacks in carbohydrates, protein, fat almost all the ingredients.

Energy equivalent to eat snacks to eat, some of the energy snack food is also very high, hard fruit such as food oil, bananas, pistachios, cashews, potato chips, extruded foods containing starch, candy, dried fruit, preserved fruit, sweet sugary drinks, Beef jerky, fish protein, the energy consumption can not be in the form of fat to be stored.

5. Drink too much

Liquor is a high-calorie drinks, 1 gram of alcohol Nengchan 7 kilocalories, second only to fat production of heat, the alcohol in beer degree Although only about 3 percent, but there are 11 per cent of the sugar degree, and drink beer The volume is much greater.

A bottle of beer production of energy equivalent to 100 grams of grain production of heat, much the same Jiuhe eat a lot of food, excess energy in the form of fat to be stored.

秋天到了,又到了人们减肥的好日子了,虽然不少人都以节食为首选的减肥方法,但是往往效果甚微。那为什么我们吃的都是一些“减肥食品”到最后不但没有成功减肥,反而还增肥了呢?原因就在于超市里的一些貌似可以减肥的食品其实是我们减肥的最大克星。就让我们——把它们“揪”出来吧。

问题1.过量蛋白质

蛋白质也是一种产能量的物质,如果吃多了,食入的能量超过了人体需要量,储存起来的还是脂肪。含蛋白质的食物多为肉类、蛋类、奶类、黄豆类、粮食,蔬菜和水果也有少量的蛋白质。

含蛋白质丰富的食物(肉、蛋、奶、黄豆)都含高脂肪,这些食物吃多了脂肪也会随着吃多了。蛋白质的代谢产物要从肾脏排泄,蛋白质吃多了会加重肾脏的负担,代谢产物超过了肾脏的排泄能力会造成“氮质血症”,对身体有害。


问题2.吃“油”太多


含蛋白质丰富的食物(肉、蛋、奶、黄豆)都含高脂肪,这些食物吃多了脂肪也会随着吃多了。蛋白质的代谢产物要从肾脏排泄,蛋白质吃多了会加重肾脏的负担,代谢产物超过了肾脏的排泄能力会造成“氮质血症”,对身体有害。 脂肪是减肥的大忌,而为了防止发胖,就要少涉入脂肪含量高的食物。杜绝脂肪类食品说白了就是少吃油,油用医学术语称之为“脂肪”,植物油和动物油都是脂肪,植物油是纯脂肪,肥肉的主要成分脂肪,脂肪还存在于瘦肉、内脏、蛋、奶、豆制品、甚至粮食里、某些蔬菜里(如:毛豆)都有一定量的脂肪。

问题3.多吃碳水化合物

1克碳水化合物或1克蛋白质只产生4千卡热量,而1克脂肪能产9千卡热量,所以多吃一点脂肪等于多吃很多的碳水化合物或蛋白质。植物油比同等重量的肥肉所含的脂肪要多,因为肥肉中除了脂肪外还含有水分、蛋白质、纤维组织。有人说:“我不吃肥肉,只吃素油,可以避免肥胖。”实质上是一种误解,瓜子、花生、核桃、松子、榛子、夏果等这些硬果类食物的成分几乎一半是脂肪。有人爱吃这些零食也等于吃了很多脂肪。有些素菜馆,做菜的油越来越大,炒菜出锅时为了好看还要洒明油,各种素“水煮鱼”、“水煮肉”、“香辣蟹”实质上是“油煮”,吃进的油不可能不超量。

碳水化合物经肠道消化变成单糖(葡萄糖、果糖、半乳糖)后被吸收入血,一部分被组织直接利用产生能量供人体需要,一部分储存在细胞里,如果还有多余的单糖,就会变成脂肪储存在机体中。含碳水化合物的食物有粮食、豆类、奶、水果、干果、蔬菜。

以前生活水平低的时候副食差,一般人每顿饭吃主食四两半斤是很平常的,现在生活水平提高了,副食好了,主食还吃四两半斤就超量了。有人吃水果太多,尤其吃含糖高的水果(香蕉、柿子、葡萄、荔枝),也增加了碳水化合物的摄入量。


问题4.零食+甜品

有些人喜欢吃零食,喝甜饮料,尤其是感到生活乏味或看电视时吃过多的零食。零食中碳水化合物、蛋白质、脂肪的成分几乎都有。

吃零食等于吃能量,有些零食的能量还很高,比如硬果类食物含油多,香蕉、开心果、腰果、薯片、膨化食品含淀粉多,糖果、干果、果脯、甜饮料含糖多,牛肉干、鱼片含蛋白质多,产生的能量消耗不了,就会以脂肪的形式储存起来。

问题5.喝酒太多

酒是产生高热量的饮料,1克酒精能产7千卡热量,仅次于脂肪产的热量,啤酒中的酒精度数虽然只有3%左右,但还有11%的含糖度数,而且喝啤酒的量要大得多。

一瓶啤酒产的热量相当于100克粮食产的热量,酒喝得多就等于多吃很多食物,多余的能量还会以脂肪的形式储存起来。
