SAMMANFATTNING

Syfte Att studera om det förelåg skillnader i hunger, sug, motivation, koncentration samt törst beroende på andelen protein i kosten vid negativ energibalans. Metod Som en del av en större interventionsstudie användes enkäter i form av självskattningskalor för att studera de olika faktorerna (hunger, sug, motivation, koncentration och törst) vid normalt respektive lågt proteinintag vid negativ energibalans. Den större studien innefattade bl a moment så som fysiska arbetsprov, biokemiska tester, direkt –och indirekt respiratorisk kalorimetri. Resultat Studien visar att ett proteinintag på 2,5 gram per kilo kroppsvikt varken ger minskad hunger eller minskat sug jämfört med vid ett proteinintag på 1.0 gram per kilo kroppsvikt. Däremot visade studien att ett ökat proteinintag gav minskad törst jämfört med ett normalt proteinintag. När det gäller motivationen ses inga betydande skillnder med avseende på proteinintaget då båda grupperna skattade sin motivation likartat. Koncentrationen hos de båda grupperna följdes åt under de första 4 dagarna för att sedan avvika från varandra under dag 5. Normalproteingruppen skattade då sin koncentration mer är dubbelt så hög som högproteingruppen.

ABSTRACT

Aim The aim of the survey was to study whether there were differences in hunger, cravings, motivation, concentration and thirst depending on the proportions of protein in the diet during negative energy balance. Method A quasi-experimental quantitative study was conducted where perceptions of hunger, cravings, motivation, concentration and thirst were assessed in young men consuming either a normal or a high protein intake during negative energy balance. Results The study shows that a protein intake of 2.5 grams per kilo of body weight neither reduced hunger nor cravings compared to a protein intake of 1.0 grams per kilo of bodyweight. However, the study showed that increased protein intake resulted in reduced thirst compared to a normal protein intake. No difference in motivation. Concentration was rated similar in both groups during the first 4 days and the last two days, but on day 5 the normal protein group rated their concentration more than twice as high as the high protein group.
