Diet High in Protein, Low on Glycemic Index Helps Prevent Weight Regain

A diet high in protein and low on the glycemic index appears to be optimal for weight control following significant weight loss, according to an international study in the New England Journal of Medicine.


Researchers randomized some 770 overweight or obese adults — who had recently lost at least 8% of their body mass — to one of five maintenance diets: high-protein/low-glycemic-index, high-protein/high-glycemic-index, low-protein/low-glycemic-index, low-protein/high-glycemic-index, or following their country's dietary guidelines.


At 6 months, the high-protein/low-glycemic-index diet group had lost additional weight (-0.38 kg), while the low-protein/high-glycemic-index diet regained the most weight (1.67 kg). Diets that were high in protein and low on the glycemic index had higher rates of study completion.


The authors conclude that a high-protein/low-glycemic-index diet "appears to be ideal for the prevention of weight regain."

Abstract
Background: Few prospective studies have examined the mortality of vegetarians.

Objective: We present results on mortality among vegetarians and nonvegetarians in the European Prospective Investigation into Cancer and Nutrition (EPIC-Oxford).

Design: We used a prospective study of men and women recruited throughout the United Kingdom in the 1990s.

Results: Among 64,234 participants aged 20–89 y for whom diet group was known, 2965 had died before age 90 by 30 June 2007. The death rates of participants are much lower than average for the United Kingdom. The standardized mortality ratio for all causes of death was 52% (95% CI: 50%, 54%) and was identical in vegetarians and in nonvegetarians. Comparing vegetarians with meat eaters among the 47,254 participants who had no prevalent cardiovascular disease or malignant cancer at recruitment, the death rate ratios adjusted for age, sex, smoking, and alcohol consumption were 0.81 ((95% CI: 0.57, 1.16) for ischemic heart disease and 1.03 (95% CI: 0.90, 1.16) for all causes of death.

Conclusions: The mortality of both the vegetarians and the nonvegetarians in this study is low compared with national rates. Within the study, mortality from circulatory diseases and all causes is not significantly different between vegetarians and meat eaters, but the study is not large enough to exclude small or moderate differences for specific causes of death, and more research on this topic is required.

Abstract
Background: In the recent World Cancer Research Fund/American Institute for Cancer Research report of diet and cancer, it was concluded that there is limited but suggestive evidence that animal fat intake increases the risk of colorectal cancer.

Objective: To clarify this potential relation, we conducted meta-analyses across a variety of subgroups, incorporating data from additional studies.

Design: Analyses of high compared with low animal fat intakes and categorical dose-response evaluations were conducted. Subgroup analyses, consisting of evaluations by study design, sex, and tumor site were also performed.

Results: Six prospective cohort studies with comprehensive dietary assessments, contributing 1070 cases of colorectal cancer and ≈1.5 million person-years of follow-up, were identified. The summary relative risk estimate (SRRE) for these studies was 1.04 (95% CI: 0.83, 1.31; P for heterogeneity = 0.221) on the basis of high compared with low intakes. When data from case-control studies were combined with the cohort data, the resulting SRRE was 1.15 (95% CI: 0.93, 1.42) with increased variability (P for heterogeneity = 0.015). In our dose-response analysis of the cohort studies, no association between a 20-g/d increment in animal fat intake and colorectal cancer was observed (SRRE: 1.02; 95% CI: 0.95, 1.09). In a separate analysis of 3 prospective cohort studies that reported data for animal protein or meat protein, no significant association with colorectal cancer was observed (SRRE: 0.90; 95% CI: 0.70, 1.15).

Conclusion: On the basis of the results of this quantitative assessment, the available epidemiologic evidence does not appear to support an independent association between animal fat intake or animal protein intake and colorectal cancer.
