    Mixed in with the useful information there's a good chance you've come across at least a couple of metabolism myths that could be sending you down the wrong path. By getting it straight from the start, you put yourself in a better position to see results.

    Here are some of the main metabolism myths you should know about.

    1. Eating Before Bed Will Lead to Fat Gain

    The first metabolic myth that many people fall for is that foods eaten before bed will automatically turn to body fat. The truth is that it's the total calorie intake over the course of the day that determines whether a food will turn to body fat or not. It doesn't matter when the calories are eaten, just that they don't put you over your total daily calorie intake.

    Spreading your calories out evenly throughout the day will help maintain a stabilized energy level, but from a fat gaining perspective, eating before bed won't cause weight gain in and of itself.

    2. Eating More Frequently Will Speed Up Your Metabolism

    Another common myth is that eating more frequent meals will boost your metabolism. If you've ever heard someone tell you that you should eat six times a day for a faster metabolism, you're being given misinformation.

    The point to remember here is that each time you eat a meal, your metabolism increases. This increase is impacted by how large the meals higher in carbohydrates and fats).

    Assuming total macronutrient composition and calorie intake stays the same over two different diets, one consisting of three meals and one of six, both diets will experience the same metabolic increases. The only difference is the individual eating six meals a day will have smaller increases six times while the other individual will have larger increases three times a day.

    3. No-Carb Diets Cause Faster Fat Loss

    When you start up on a very low carbohydrate diet such as Atkins or a Ketogenic diet, you enter into what is referred to as ketosis, where your body switches from running on carbohydrates as fuel to using a source called ketones. Many individuals believe that there is something special about being in ketosis that speeds up the rate of fat loss you experience.

    This is not the case. Low carb diets offer the benefit of hunger control, but in terms of actually changing the rate of the metabolism, they're not going to have any influence. In fact, if you go without carbohydrates for too long, your metabolism could decrease because carbohydrates are the main macronutrient that influences the thyroid gland.

    關于新陳代謝問題,人們在接收到一些有用的信息的同時也會接收到一些錯誤的觀點。如果從一開始你接收到的信息就是正確的話,你會比別人收到更好的效果。

    以下是關于身體代謝的幾個常見認識誤區(qū)。

    1、睡前吃東西將轉換為脂肪吸收。

    第一個大家普遍認為的新陳代謝誤區(qū)是,睡前吃東西將會自動轉換為脂肪吸收。事情的真相是你一整天的熱卡攝取量決定你吃的事物是否會轉變程脂肪。不管你什么時候吃東西都沒關系,只要它不超過你一天熱卡需求量。

    每天均衡攝取熱卡將有助于你保持能量平衡,但是從脂肪增重的角度來說,睡前吃東西并不會增加你的體重。

    2、一日多餐會加速身體新陳代謝

    另一個誤區(qū)是一日多餐會加速身體新陳代謝。如果有人告訴你應該一天吃6餐加速新陳代謝,那么你被騙了。

    有一點你應該知道是每吃一次飯,你的新陳代謝就會增加。增加量主要由飯餐里的碳水化合物和脂肪量決定的。

    一日三餐和一日六餐這兩種不同的就餐方法,如果他們提供的營養(yǎng)物質和熱卡量都相同的話,那么他們各自引起的新陳代謝增加量也是相同的。唯一不同是每日六餐每次新陳代謝增加比較小,而另一個一日三餐的方法,每次新陳代謝增加量比較大。

    3、不含碳水化合物的飲食可以去除身體多余脂肪

    當你開始每天食用低碳水化合物的食品例如減肥專家或者生酮膳食,也就和糖尿病酮癥患者的飲食差不多了,即本來以碳水化合物為身體主要能量變成依靠酮體作為身體能量。許多人認為這種可以加快減肥速度減肥方法比較特別。

    事實不是這樣,低碳水化合物飲食可控制人的饑餓感,但是事實上它并沒有改變了新陳代謝的速率。如果你長時間不食用含碳水化合物食品,你的新陳代謝就會減少,因為碳水化合物是影響甲狀腺的主要營養(yǎng)物質。
