Gezond in 21 dagen*
Uit een kleine studie onder 29 deelnemers, 12 mannen en 17 vrouwen blijkt dat
21 dagen een speciaal dieet een aanzienlijke verbetering geeft in zowel
cholesterol, bloeddruk, bloedsuikerwaarden, insuline resistentie en
lichaamsgewicht. Het dieet was vegetarisch, zonder dierlijke producten, geen
geraffineerde producten, geen wit meel, geen conserveermiddelen, geen
zoetstoffen, geen cafeïne en geen alcohol. De ene helft kreeg ook dagelijks
een supplement met krilolie met hoofdzakelijk omega-3 vetzuren. De inname van
dit supplement veranderde niets aan de uitkomsten.

Abstract (provisional)
Background
The Daniel Fast is a vegan diet that prohibits the consumption of animal products, refined foods, white flour, preservatives, additives, sweeteners, flavorings, caffeine, and alcohol. Following this dietary plan for 21 days has been demonstrated to improve blood pressure, LDL-C, and certain markers of oxidative stress, but it has also been shown to lower HDL-C. Krill oil supplementation has been shown to increase HDL-C.
Methods
We investigated the effects of following a Daniel Fast dietary plan with either krill oil supplementation (2 g/day) or placebo supplementation (coconut oil; 2 g/day) for 21 days. The subjects in this study (12 men and 27 women) were heterogeneous with respect to body mass index (BMI) (normal weight, overweight, and obese), blood lipids (normolipidemic and hyperlipidemic), blood glucose (normal fasting glucose, impaired fasting glucose, and type 2 diabetic), and blood pressure (normotensive and hypertensive).
Results
Krill oil supplementation had no effect on any outcome measure (all p > 0.05), and so the data from the krill oil group and the placebo group were collapsed and analyzed to examine the effects of following a 21-day Daniel Fast. Significant reductions were observed in LDL-C (100.6 +/- 4.3 mg/dL vs. 80.0 +/- 3.7 mg/dL), the LDL:HDL ratio (2.0 +/- 0.1 vs. 1.7 +/- 0.1), fasting blood glucose (101.4 +/- 7.5 mg/dL vs. 91.7 +/- 3.4 mg/dL), fasting blood insulin (7.92 +/- 0.80 muU/mL vs. 5.76 +/- 0.59 muU/mL), homeostasis model assessment of insulin resistance (HOMA-IR) (2.06 +/- 0.30 vs. 1.40 +/- 0.21), systolic BP (110.7 +/- 2.2 mm Hg vs. 105.5 +/- 1.7 mm Hg), and body weight (74.1 +/- 2.4 kg vs. 71.5 +/- 2.3 kg) (all p < 0.05).
Conclusion
Following a Daniel Fast dietary plan improves a variety of cardiometabolic parameters in a wide range of individuals in as little as 21 days, and these improvements are unaffected by krill oil supplementation.
