Studie: Redan fyra veckor med ketogen kost ger stor viktnedgång och förbättrad hälsa vid fetma

En ny koststudie har gjorts på patienter som står i begrepp att utföra magsäcksoperation, typ gastric bypass. Deltagarna fick en ketogen kost berikad med mikronäringsämnen. Alla deltagare fick fantastiskt fina resultat, och ingen hade något problem med att följa kosten heller (så varför inte skippa operationen helt och hållet kan man ju fråga sig).

På bara fyra veckor tappade deltagarna ungefär 10% kroppsvikt, de minskade fettlever (leverstorlek) och förbättrade sin näringsstatus – för att bara nämna några saker.

“4-Week Preoperative Ketogenic Micronutrient-Enriched DietIs Effective in Reducing Body Weight, Left Hepatic Lobe Volume,and Micronutrient Deficiencies in Patients Undergoing BariatricSurgery: a Prospective Pilot Study”

“Background Before bariatric surgery (BS), moderate weight loss, left hepatic lobe volume reduction, and micronutrient deficiency (MD) identification and correction are desirable.

Objectives The objective of this study was to assess the safety and the effectiveness of a 4-week preoperative ketogenic micronutrient-enriched diet (KMED) in reducing body weight (BW), left hepatic lobe volume, and correcting MD in patients scheduled for BS.

Materials and Methods In this prospective pilot study, a cohort of morbidly obese patients (n = 27, 17 females, 10 males) with a mean body mass index (BMI) of 45.2 kg/m2 scheduled for BS underwent a 4-week preoperative KMED. Their BW, BMI, fatmass (FM), fat-free mass (FFM), resting metabolic rate (RMR), left hepatic lobe volume, micronutrient status, and biochemicaland metabolic patterns were measured before and after the 4-week KMED. Patient compliance was assessed by validatedquestionnaires (3-day estimated food records and 72-h recall). Qualitative methods (5-point Likert questionnaire) were used to measure diet acceptability and side effects.

Results All patients completed the study. We observed highly significant decreases in BW (− 10.3%, p < 0.001, in males; − 8.2%,p < 0.001, in females), left hepatic lobe volume (− 19.8%, p < 0.001), and an amelioration of patient micronutrient status. All patients showed a high frequency of acceptability and compliance in following the diet. No adverse side effect was reported.

Conclusion This study demonstrates that a 4-week preoperative KMED is safe and effective in reducing BW, left hepatic lobevolume, and correcting MD in obese patients scheduled for BS.”
