Paleolitisk kost mer mättande per kalori än medelhavskost

Abstract (provisional)

Background
We found marked improvement of glucose tolerance and lower dietary energy intake in ischemic heart disease (IHD) patients after advice to follow a Paleolithic diet, as compared to a Mediterranean-like diet. We now report findings on subjective ratings of satiety at meals and data on the satiety hormone leptin and the soluble leptin receptor from the same study.

Methods
Twenty-nine male IHD patients with impaired glucose tolerance or diabetes type 2, and waist circumference > 94 cm, were randomized to ad libitum consumption of a Paleolithic diet (n=14) based on lean meat, fish, fruit, vegetables, root vegetables, eggs, and nuts, or a Mediterranean-like diet (n=15) based on whole grains, low-fat dairy products, vegetables, fruit, fish, and oils and margarines during 12 weeks. In parallel with a four day weighed food record the participants recorded their subjective rating of satiety. Satiety Quotients were calculated, as the intra-meal quotient of change in satiety during meal and consumed energy or weight of food and drink for that specific meal. Leptin and leptin receptor was measured at baseline and after 6 and 12 weeks. Free leptin index was calculated as the ratio leptin/leptin receptor.

Results
The Paleolithic group were as satiated as the Mediterranean group but consumed less energy per day (5.8 MJ/day vs. 7.6 MJ/day, Paleolithic vs. Mediterranean, p=0.04). Consequently, the quotients of mean change in satiety during meal and mean consumed energy from food and drink were higher in the Paleolithic group (p=0.03). Also, there was a strong trend for greater Satiety Quotient for energy in the Paleolithic group (p=0.057). Leptin decreased by 31% in the Paleolithic group and by 18% in the Mediterranean group with a trend for greater relative decrease of leptin in the Paleolithic group. Relative changes in leptin and changes in weight and waist circumference correlated significantly in the Paleolithic group (p<0.001) but not in the Mediterranean group. Changes in leptin receptor and free leptin index were not significant.

Conclusions
A Paleolithic diet is more satiating per calorie than a Mediterranean-like diet.

Har inte ett skit med saken att göra.

För övrigt är inte resultaten speciellt uppseendeväckande. Skrev om den lite kort på bloggen.

A new study on the Paleo diet came out two days ago: "A Paleolithic diet is more satiating per calorie than a Mediterranean-like diet in individuals with ischemic heart disease." You can download the full text free.

This was a Swedish study and most of the authors actually live nearby. Staffan Lindeberg is a long-time and fairly well known proponent of the paleo diet. The name should ring a bell for anyone who's done their reading on paleolithic nutrition.

The diet approach used in this study was "ad libitum", meaning that participants could eat as much as they wanted out of a few food groups. Based on the food logs, protein intake was estimated to be 27% and 20% in the paleo and Mediterranean diet respectively. The results aren't really that surprising, as high-protein diets always come out on top. I've talked about the effects of various macronutrients in "Cheat Day Strategies for The Hedonist."

Jo det kanske inte är så konstigt att en diet med mer protein är mer mättande. Men å andra sidan är det väl lite av fördelen med "paleolitisk kost" när man äter ad libitum av den. Det är ju förstås inget magiskt utan man kan ju sätta ihop dieter med andra restriktioner som fungerar lika bra eller bättre m a p mättnad.
Förstår dock om han är en förespråkare av paleo att han gärna gör en sådan här studie för att få vatten på sin kvarn
