Hei
I et mastergradsstudie ved Norges idretshøyskole har mastergradsstudent Pål Jåbek, og medarbeidere, undersøkt efekten av ketolysekuren kombinert med trening og normal diett kombinert med trening.

Artikkelen er publisert i det anerkjente tidsskrift Nutrition & Metabolism og viser at man på ketogen diett går ned i vekt ved å miste fett, ikke muskler. På 10 uker mistet deltakerne i gjennomsnitt 5,6 kilo fett. Det var ingen endring av muskelmassen.
Dette uten negative endringer av blodfetter eller fastende blodsukker.
Gruppen som fikk trening kombinert med normal diett hadde ingen endring av fettmassen men en vektøkning på 1,6 kilo på grunn av økt muskelmasse.

Min konklusjon er at ketolysekuren kombinert med trening fjerner fett fra kroppen uten å redusere muskelmassen. Og dette uten negative effekter på kolesterol og de øvrige blodfetter samt blodsukker.
Trening kombinert med normal kosthold gir vektøkning på grunn av økt muskelmasse uten at fettmassen reduseres.
Trening alene uten endringer av kostholdet er ikke en god måte å redusere kroppens fettmasse på.

Abstract (provisional)



Background

The aim of the present study was to compare the effects of 10 weeks resistance training in combination with either a regular diet (Ex) or a low carbohydrate, ketogenic diet (Lc+Ex) in overweight women on body weight and body composition.
Methods

18 untrained women between 20 and 40 years with BMI [greater than or equal to] 25 kg*m-2 were randomly assigned into the Ex or Lc+Ex group. Both groups performed 60-100 min of varied resistance exercise twice weekly. Dietary estimates were based on two 4-day weighed records. Body composition was estimated using Dual Energy X-ray Absorptiometry. Fasting blood samples were analyzed for total-, HDL- and LDL-cholesterol, triacylglycerols, and glucose.
Results

16 subjects were included in the analyses. Percentage of energy (En%) from carbohydrates, fat and protein was 6, 66, and 22 respectively in the (Lc+Ex) group and 41, 34, 17 in the Ex group. Mean weight change (pre-post) was -5.6 +/- 2.6 kg in Lc+Ex; (p<0.001) and 0.8 +/- 1.5 kg in Ex; (p=0.175). The Lc+Ex group lost 5.6 +/- 2.9 kg of fat mass (p=0.001) with no significant change in lean body mass (LBM), while the Ex group gained 1.6 +/- 1.8kg of LBM (p=0.045) with no significant change in fat mass (p=0.059). Fasting blood lipids and blood glucose were not significantly affected by the interventions.
Conclusion

Resistance exercise in combination with a ketogenic diet may reduce body fat without significantly changing LBM, while resistance exercise on a regular diet may increase LBM without significantly affecting fat mass. Fasting blood lipids do not seem to be negatively influenced by the combination of resistance exercise and a low carbohydrate diet.
