Most people are engaged in different weight loss programs with the hope of losing weight.
很多人都參加了不同的減肥項目，希望能成功減肥。
But, have you ever stopped to ask yourself what is it that helps people to lose weight? The simple answer is, 'calories you take in versus the calories you expend'. For you to be able to calculate and effectively burn the calories to lose weight, you need to understand what calories are.
但你有沒有停下來問問自己：到底是什麼幫助人們減肥了呢？答案很簡單"你攝入的卡路里量對比你消耗的卡路里量"。減肥時，爲使自己能夠計算出並高效燃燒卡路里，你需要明白什麼是卡路里。
What are calories?
什麼是卡路里？
In nutrition, calories are defined as the unit of energy that is obtained from foods and drinks. Your body cells need the calories to function normally and that is why you need to ensure that you meet your daily calorie intake. What you need to understand is that any food item that contains calories has the potential to increase your energy intake. Now, people who don't understand the importance of calories in the body, end up gaining or losing too much weight.
營養學對卡路里的定義是：從食物和飲料中獲得的能量單位。你的身體細胞需要卡路里才能正常運轉，這也就是爲什麼你需要確保每日卡路里攝入量都達到了標準。你需要理解的是：任何含有卡路里的食物都具備增加你能量攝入的潛能。現在，人們並不理解體內卡路里的重要性，其結果要不就是增重太多，要不就是變得太瘦。
To be able to understand the dynamics of weight loss and weight gain, you need to understand what the calories are and what their role is in their body.
爲了能瞭解體重減少與體重增加的動態，你需要了解卡路里是什麼，以及它們在體內所扮演的角色。
Calories as mentioned above are units of energy. They are the ones that provide the body with energy for its normal functions. However, the calorie intake is directly linked to the energy expenditure.
如上所述，卡路里是能量單位。它們可供給身體能量，使身體正常運轉。然而，攝入的卡路里量是與消耗的能量直接關聯的。
This means that for you to be able to lose weight, the energy expenditure needs to be higher than the calorie intake. To gain weight, you need to maintain a higher energy intake than the energy expenditure, i.e. a caloric surplus. The opposite is true if you want to lose weight wherein you must burn more than you take in.
這就意味着如果你想成功減肥，那麼能量的消耗要高於卡路里的攝入。想要增重的話，你的能量攝入就要高於能量消耗，也就是說，要有剩餘的卡路里。反過來也是成立的，即：如果你想要減肥，那麼燃燒的卡路里量必須要高於攝入的卡路里量。
