University of Copenhagen

Status: Completed

Conditions: Overweight

Treatments: Other: Veal and carbohydrats with low or high GI; Other: Fish and carbohydrats with low or high GI

Study type: Interventional

About

The hypothesis is that seafood proteins given in combination with carbohydrates with low GI are superior to seafood proteins in combination with carbohydrates with high GI and meat in combination with both carbohydrates with low and high GI in promoting energy expenditure and satiety. The overall objective of this study is to investigate the acute effects of meals containing fish versus meat proteins on energy balance (thermogenesis, appetite regulating hormones and appetite sensations), markers of glucose allostatis and amino acid metabolism.

48 participants in 2 patient groups

Salmon vs. veal and CHO with low or high GI

Experimental group

Description:

In the first clinical study (Study 1), subjects will eat salmon or veal combined with high or low GI carbohydrates. Each subject will be engaged in each of the following four 1-day test meals: * Meat balls with salmon served with tomato sauce and other accompaniments with low GI * Meat balls with salmon served with tomato sauce and other accompaniments with high GI * Meat balls with veal served with tomato sauce and other accompaniments with low GI * Meat balls with veal served with tomato sauce and other accompaniments with high GI

Treatment:

Other: Veal and carbohydrats with low or high GI

Other: Fish and carbohydrats with low or high GI

Cod vs. veal and CHO with low or high GI

Experimental group

Description:

In the second clinical study (Study 2), subjects will eat codfish or veal combined with high or low GI carbohydrates. Each subject will be engaged in each of the following four 1-day test meals: * Meat balls with codfish served with tomato sauce and other accompaniments with low GI * Meat balls with codfish served with tomato sauce and other accompaniments with high GI * Meat balls with veal served with tomato sauce and other accompaniments with low GI * Meat balls with veal served with tomato sauce and other accompaniments with high GI

Treatment:

Other: Veal and carbohydrats with low or high GI

Other: Fish and carbohydrats with low or high GI
