近來，由北卡羅來納州大學(xué)研究者完成的一項研究證實：肥胖人群要想達(dá)到減肥的目的除了使用適當(dāng)?shù)臏p肥藥物外，或許通過喝水或軟飲料來攝取卡路里后，我們體重就可以減輕減4至5鎊。

研究人員招募了318名體重超重者或極度肥胖患者參與了這項減肥研究，工作人員將這些人分成三組。一組人所飲用的飲品為軟飲料，而不是能量較高的飲料，一組人的飲品為水，給最后一組人供應(yīng)一些有助減肥的飲品飲用，但最后一組人并不知道這些飲品的具體功效。

結(jié)果這三組人在6個月內(nèi)都出現(xiàn)了多多少少的體重減輕或是腰圍變小現(xiàn)象，研究人員認(rèn)為這些人體重的下降率以及血糖含量的降低是非常有益處的，血糖含量的降低能減少肥胖患者的致病因素。

研究者發(fā)現(xiàn)水或是蘇打水這兩種飲品對減肥有很大幫助，但或許蘇打水對減肥的功效或許比水更明顯，因為那些傾向于甜味、碳酸口味或是含咖啡因的飲料的人（通常體重都叫肥胖）在該項研究中更傾向于蘇打水，而不是用水代替上述飲料。

另外，該研究還證實如果減肥者參與集體減肥活動，在有計劃指導(dǎo)下進(jìn)行減肥的話，可能減肥效果更好。研究人員表示：肥胖人群要是能稍微進(jìn)行自我監(jiān)控自己的飲食習(xí)慣（例如飲料）就能幫助我們增加減肥效果。

研究人員呼吁肥胖者要改變自己的飲料習(xí)慣，應(yīng)時刻提醒自己要少飲用那些高能量的飲料，合理飲用水或是蘇打水等能量低的飲料。

Replacing caloric beverages with water or diet beverages for weight loss in adults: main results of the Choose Healthy Options Consciously Everyday (CHOICE) randomized clinical trial

Background: Replacement of caloric beverages with noncaloric beverages may be a simple strategy for promoting modest weight reduction; however, the effectiveness of this strategy is not known.

Objective: We compared the replacement of caloric beverages with water or diet beverages (DBs) as a method of weight loss over 6 mo in adults and attention controls (ACs).

Design: Overweight and obese adults [n = 318; BMI (kg/m2): 36.3 ± 5.9; 84% female; age: 42 ± 10.7 y; 54% black] substituted noncaloric beverages (water or DBs) for caloric beverages (≥200 kcal/d) or made dietary changes of their choosing (AC) for 6 mo.

Results: In an intent-to-treat analysis, a significant reduction in weight and waist circumference and an improvement in systolic blood pressure were observed from 0 to 6 mo. Mean (±SEM) weight losses at 6 mo were 2.5 ± 0.45% in the DB group, 2.03 ± 0.40% in the Water group, and 1.76 ± 0.35% in the AC group; there were no significant differences between groups. The chance of achieving a 5% weight loss at 6 mo was greater in the DB group than in the AC group (OR: 2.29; 95% CI: 1.05, 5.01; P = 0.04). A significant reduction in fasting glucose at 6 mo (P = 0.019) and improved hydration at 3 (P = 0.0017) and 6 (P = 0.049) mo was observed in the Water group relative to the AC group. In a combined analysis, participants assigned to beverage replacement were 2 times as likely to have achieved a 5% weight loss (OR: 2.07; 95% CI: 1.02, 4.22; P = 0.04) than were the AC participants.

Conclusions: Replacement of caloric beverages with noncaloric beverages as a weight-loss strategy resulted in average weight losses of 2% to 2.5%. This strategy could have public health significance and is a simple, straightforward message. This trial is registered at clinicaltrials.
