Brief Summary:
Part 1 of this research demonstrated that type II diabetics are lacking in knowledge of how to best treat their illness with dietary controls Most had little nutrition or diabetes knowledge Part 2 demonstrated that providing a 40 reduction in fat intake across three meals versus all at one meal was more effective in glycemic control Part 3 is designed to incorporate these findings into a long-term free living setting through education and behaviordietary modification
Detailed Description:
Participants will be randomized into either the test group or the control group Both groups will complete a one-week run-in period and then be followed over a 16 week period This study will be conducted in two cohorts of 50 participants with 25 test participants and 25 control participants in each cohort
Run-in Week - On the first day participants will report to the laboratory for initial orientation to the study and methods Baseline body measurements height weight and body composition analysis using Bioelectrical Impendance and a fasting blood sample blood pressure and pulse will be taken Participants will also complete additional study questionnaires and records Table 1 provides a summary of all measures at baseline and across the 16 week test period Participants will also taste and rate various fat-replaced foods and complete a log of any changes in health over the next 3 days to determine palatability and tolerance of fat-replaced foods Before trying foods a survey will be administered to check for common food allergies Finally participants will be instructed to complete food diaries for 2 weekdays and 1 weekend day Participants will return the food diaries and logs the following week Participants who 1 do not complete all parts of the run-in phase 2 do not like and are not willing to eat at least 80 of the tested foods or 3 have negative health effects following consumption of the foods will be dismissed from the study No manipulations to participants diets will occur during this phase
16-Week Test Phase - During this phase the test group will be given fat-replaced foods and instructed in a detailed diet plan to create a low-fat 25 kcal from fat weight maintenance diet providing optimal glycemic control The test group will attend a 1h educational session didactic and discussion every 2wks Appendix 2 lists course topics Academic and professional staff will lead the sessions Participants will be required to keep logs of certain behaviors and food records 2 weekdays and 1 weekend day over the 2wk period Prior to the educational meetings participants will submit data collection sheets questionnaires and logs be weighed and scheduled measures Following the meeting participants will be given fat-replaced foods for use over the next 2 weeks Participants will be instructed to keep a log of usage of the provided foods explicitly told that the foods are not for use by other members of their household and will be required to return all remaining or unused foods to the laboratory at the next meeting In addition at 8 weeks and 16 weeks a blood sample body composition psychometrics waisthip measurements blood pressure and pulse will be taken The control group will receive vouchers for local supermarkets to offset the cost of the foods provided to the test group but will not be given actual food This group will come to the laboratory every 2 weeks for identical data collection including blood draws but will not attend educational sessions Instead the control group will receive a newsletter every two weeks about the importance of a low-fat diet in the management of type II DM however this newsletter will not give specific information about the use of fat-replaced foods in a low-fat diet This newsletter will be sent to the test group as well
Diet The test group diet plan will be designed to be a weight maintenance diet which derives no more than 25 kcal from fat no more than 10 from saturated fat A Registered Dietitian will design an individually tailored 7d rotating suggested meal plan which includes the detailed use of fat-replaced foods according to the optimal strategy identified in Experiment 2 The individual prescriptions will be based upon the Mifflin-StJoer equation and baseline intake obtained from the diet records from the run-in week
