The effect of intermittent fasting on insulin sensitivity was measured by change in homeostatic model assessment of insulin resistance (HOMA-IR) between baseline and week 12. Homeostasis model assessment of insulin resistance (HOMA-IR) is a method to measure insulin sensitivity. Optimal insulin sensitivity is a HOMA-IR ratio less than 1. Levels above 1.9 signal early insulin resistance, while levels above 2.9 signal significant insulin resistance.

SECONDARY outcome

Timeframe: Assessed before 12-week intervention (baseline) and at week 12

Population: Analysis only includes subjects who completed study through week 12. Unable to obtain a Fibroscan on 10 participants because of body habitus.

The effect of Intermittent fasting on body composition was evaluated using Controlled Attenuation Parameter (CAP) score from Fibroscan. Measurement of controlled attenuation parameter (CAP) is a non-invasive quantitative and qualitative assessment of liver steatosis. CAP measures ultrasonic attenuation (in dB/m) at a frequency of 3.5 MHz (on a go-and-return path). Values range from 100 to 400 dB/m. Higher levels indicate increased hepatic fat.

The effect of Intermittent fasting on mood was evaluated by change in the Beck Depression Inventory (BDI) score between baseline and week 12. The Beck Depression Inventory (BDI) is a 21-item measure of depression with each question on a 4-point scale ranging from 0=minimal to 3 = more severe (full list score values = 0,1,2,3). Total scores are a sum of individual items. Minimal depression = 0-13, mild depression = 14-19, moderate depression = 20-28, and severe depression = 29-63. The maximum score is 63 and the minimum possible score is zero.

SECONDARY outcome

Timeframe: Compliance reported at Week 12

Population: Analysis only included subjects who completed study through week 12. 11 subjects did not report their compliance rate.

Compliance with assigned diet was assessed by participant self-reported rating. Participants used a self rating score of 0-100% with 0% = noncompliant and 100% = completely compliant with assigned diet. Compliance rate per participant was calculated using average of all daily reported scores. The overall compliance rate was averaged over all participants to get the mean compliance.
