The Effect of a Meatless,Keto Restrictive Diet on Body Composition,Strength Capacity,Oxidative Stress,Immune Response
Sponsor: Katarzyna Siedzik
Summary
The subject of doctoral dissertation: Assessment of the effects of a meatless, ketogenic restrictive diet on body composition, strength capacity, oxidative stress and immune response During planning of research and topic of the doctoral dissertation, it was considered how to modify a standard ketogenic diet rich in saturated fatty acids so that the use of this model of nutrition has the most anti-inflammatory effect. Therefore, it was decided to conduct a research to check whether a diet rich in omega-3 polyunsaturated fatty acids will show such an effect when following a high-fat diet. Hypotheses: 1\. The ketogenic diet reduces systemic inflammation. 2.The ketogenic diet reduces oxidative stress. 3. The ketogenic diet reduces body fat. 4. A ketogenic diet does not worsen strength performance.

Meatless, restrictive ketogenic diet
Each participant received a nutritional plan that was the same qualitatively but differed quantitatively - a 500 kcal reduction based on Estimated Energy Requirement (EER) was assumed. Before the start of the study, each participant obtained information about the basic principles of the ketogenic diet. Diet was designed to be isoproteic (1.6gxKg-1xbody weight-1xday-1) with three meals a day. The distribution of macronutrients during the very low carbohydrate ketogenic diet (KD) was: protein 1.6 gxKg-1xbody weight-1xday-1(\~25-30%), fats (\~65-70%,with a strong emphasis on the content of omega 3 fatty acids) and carbohydrate (\<30gxday-1;\<10%). The food lists encouraged the consumption of fish,raw and cooked vegetables, eggs,fruits with the lowest glycemic index (blueberry, raspberry), plant oils and fats from avocado,olives.Drinks permitted were tea, coffee without sugar and the foods and drinks to be avoided were alcohol,meat (any kind of meat),bread,pasta,rice,milk,dairy and potatoes.
