Randomization description
The first step is to create a random sequence number. For this purpose, we will use a random number generator on Stattrek (https://stattrek.com/statistics/random-number-generator.aspx) for 75 numbers range from 1 to 3 (for example: 2 1 3 1 2 1 2 1 1 3 3 3 3 2 2 3 2 3 1 1 2 2 3 3 1 2 2..............).Then, we will specify the numbers to the groups for example, 1 will be assigned to the intervention group one (fasting diet 2/5), the numbers 2 to the intervention group two (fasting diet 8/16 combined with a low-sugar ediet ), the numbers 3 to the control group. Each number will represent a group according to the defined numbers. With this method, we will have a specific sequence of 75 codes of 1, 2, 3 , which shows the first to seventy-fifth people who are going to be entered in the study in each group. We write the codes on a piece of paper and put them in an envelope to use during sampling. Thus, after reviewing the inclusion criteria and if the participants desire, we will enter each person included in the study according to our predetermined list.
