The Weight Watchers Diet 卡路里飲食法
Philosophy： Portion control. Nothing is off-limits, but everything must be in moderation.
How It Works： Smaller portions mean fewer calories are taken in, so less fat gets stored. A point system assigns a value to portions of all sorts of foods to help tabulate-and limit-daily consumption. To lose half a kilogram a week, you generally need to consume 500 fewer calories a day.
Downside：Hunger. Small portions can leave stomachs growling.
關(guān)鍵詞：食量控制。食物不受控制，但限制攝入量。
原理：較少食量，降低攝入熱量，減少脂肪囤積。食物卡路里表標(biāo)明了每種食物的熱量值，據(jù)此將每日攝入食物做成表格，便于控制。如果想一周減1斤，通常你每天吸收的熱量得低于500 卡。
缺點(diǎn)：饑餓。吃得少，你的胃會(huì)很難受。
