Background

Obesity is increasingly prevalent, yet the nutritional management remains contentious. It has been suggested that low glycaemic index or load diets may stimulate greater weight loss than higher glycaemic index or load diets or other weight reduction diets.

Objectives

To assess the effects of low glycaemic index or load diets for weight loss in overweight or obese people.

Search methods

Trials were identified through The Cochrane Library, MEDLINE, EMBASE, CINAHL and manual searches of bibliographies.

Selection criteria

Randomised controlled trials comparing a low glycaemic index or load diet (LGI) with a higher glycaemic index or load diet or other diet (Cdiet) in overweight or obese people.

Data collection and analysis

Two authors independently selected trials, assessed quality and extracted data, including any information provided on adverse effects.

Main results

We identified six eligible randomised controlled trials (total of 202 participants). Interventions ranged from five weeks to six months duration with up to six months follow-up after the intervention ceased. The decrease in body mass (WMD -1.1 kg, 95% confidence interval (CI) -2.0 to -0.2, P < 0.05) (n = 163), total fat mass (WMD -1.1 kg, 95% CI -1.9 to -0.4, P < 0.05) (n =147) and body mass index (WMD -1.3, 95% CI -2.0 to -0.5, P < 0.05) (n = 48) was significantly greater in participants receiving LGI compared to Cdiets. The decrease in total cholesterol was significantly greater with LGI compared to Cdiets (WMD -0.22 mmol/L, 95% CI -0.43 to -0.02, P < 0.05), as was the change in LDL-cholesterol (WMD -0.24 mmol/L, 95% CI -0.44 to -0.05, P < 0.05). No study reported adverse effects, mortality or quality of life data.

Authors' conclusions

Overweight or obese people on LGI lost more weight and had more improvement in lipid profiles than those receiving Cdiets. Body mass, total fat mass, body mass index, total cholesterol and LDL-cholesterol all decreased significantly more in the LGI group. In studies comparing ad libitum LGI diets to conventional restricted energy low-fat diets, participants fared as well or better on th LGI diet, even though they could eat as much as desired. Lowering the glycaemic load of the diet appears to be an effective method of promoting weight loss and improving lipid profiles and can be simply incorporated into a person's lifestyle. Further research with longer term follow-up will determine whether improvement continues long-term and improves quality of life.

Low glycaemic index or low glycaemic load diets for overweight and obesity

There is a lack of consensus as to the best nutritional management of obesity. We assessed the effects of low glycaemic index or glycaemic load diets in overweight or obese people. Six randomised controlled trials, involving 202 participants, were analysed. Interventions ranged from five weeks to six months duration. Participants receiving the low glycaemic index or load diet lost a mean of one kilogramme more than those on comparison diets. Lipid profile also improved more in participants receiving the low glycaemic index or load diet. No study reported adverse effects, mortality or quality of life data.

背景

低升糖指數或低升糖負荷飲食對體重過重與肥胖者的作用

肥胖的盛行率在增加中,而營養方面的處置仍有爭議。低升糖指數或低負荷飲食已經被認為是比高升糖指數或高負荷飲食或其他減重飲食更能促使體重減輕。

目標

評估低升糖指數或低負荷飲食對體重過重或肥胖者減輕體重之效果。

搜尋策略

試驗是通過考科藍圖書館, MEDLINE, EMBASE, CINAHL,以及人工搜尋參考文獻的方式獲得。

選擇標準

隨機對照試驗比較低升糖指數或低負荷飲食與高升糖指數或高負荷飲食或其他飲食對體重過重或肥胖者之影響。

資料收集與分析

兩個作者獨立地選擇試驗,評估品質及選取數據,包括任何有關副作用的資訊。

主要結論

我們發現六個合適的隨機對照試驗(總共有202位受試者)。給予處置時間五星期到六個月並且在介入處置停止後追蹤六個月。接受低升糖指數飲食組的受試者比對照組在身體質量(WMD −1.1 kg, 95% 信賴區間 −2.0 到 −0.2, P < 0.05) (n = 163),總脂肪質量(WMD −1.1 kg, 95% 信賴區間 −1.9 到 −0.4, P < 0.05) (n = 147)及身體質量指數(WMD −1.3, 95% 信賴區間 −2.0 到 −0.5, P < 0.05) (n = 48) 之下降都比較大。接受低升糖指數飲食組的受試者比對照組在總膽固醇之下降也比較大(WMD −0.22 mmol/L, 95% CI −0.43 to −0.02, P < 0.05), 低密度膽固醇之改變也是如此(WMD −0.24 mmol/L, 95% CI −0.44 to −0.05, P < 0.05)。沒有研究報告有關於副作用,死亡率及生活品質等資料。

作者結論

體重過重或肥胖者接受低升糖指數飲食比對照組能減少較多的重量並改善血脂肪之數據。接受低升糖指數飲食組的身體質量、總脂肪質量、身體質量指數、總膽固醇及低密度膽固醇之下降都顯著較大。在比較隨意接受低升糖指數飲食者與常見的限制熱量的低脂飲食者之比較中發現,雖然他們能夠吃如渴望中的一樣多,但低升糖指數飲食組的受試者較對照組有一樣或更好的進展。減少飲食中的升糖負荷是一個有效促進體重下降及改善血脂肪數據的方法並且能簡單地融入一個人的生活形態。進一步長期追蹤的研究將能決定這種改善是否能長時間持續及改善生活品質。

總結

體重過重或肥胖者接受低升糖指數飲食比高升糖指數飲食或其他減重飲食能減少更多的體重而且心血管疾病之危險指標能改善。目前對肥胖者的最好之飲食處置仍無共識。我們評估低升糖指數或低升糖負荷飲食對體重過重或肥胖者之效果。分析六個隨機對照試驗,202位受試者。給予處置時間五星期到六個月。接受低升糖指數或負荷飲食組的受試者比對照組多下降一公斤。接受低升糖指數或負荷飲食組的受試者之血脂肪數據也有改善。沒有研究報告有關於副作用,死亡率及生活品質等資料。

Dijeta s niskim glikemijskim indeksom ili niskim glikemijskim opterećenjem za pretilost

Još uvijek nije poznato koji je najbolji način prehrane za liječenje pretilosti. Cochrane sustavni pregled istražio je učinke dijete s niskim glikemijskim indeksom ili niskim glikemijskim opterećenjem na tjelesnu težinu pretilih ljudi. Analizirano je šest randomiziranih kontrolnih pokusa koji su uključili ukupno 202 ispitanika. Trajanje intervencija bilo je u rasponu od 5 tjedana do 6 mjeseci. Ispitanici koji su bili na dijeti baziranoj na niskom glikemijskom indeksu ili niskom glikemijskom opterećenju izgubili su prosječno 1 kilogram više od onih na usporednim dijetama. Kod njih je poboljšan i lipidni profil. Nijedna studija nije opisala nuspojave, smrtnost ni podatke o kvaliteti života.
