Intermittent fasting and caloric restriction for weight loss: a systematic review
Intermittent fasting (IF) and daily calorie restriction (DCR) are nutritional strategies that have been widely adopted and compared with each other. This paper aims to compare the effects of IF and DCR on the alteration of biochemical markers and body composition. The PRISMA recommendation was used...

| Sumario: | Intermittent fasting (IF) and daily calorie restriction (DCR) are nutritional strategies that have been widely adopted and compared with each other. This paper aims to compare the effects of IF and DCR on the alteration of biochemical markers and body composition. The PRISMA recommendation was used for the elaboration of the work, and 20 randomized clinical trials were included in the qualitative synthesis. There were no differences between IF and DCR in six studies evaluating blood glucose; four studies evaluating triglycerides; six studies evaluating insulin; all studies evaluating total cholesterol, homocysteine ​​and glycated hemoglobin; four studies that evaluated LDL cholesterol; five studies that evaluated HDL cholesterol; two studies that evaluated HOMA-IR; three studies that evaluated leptin; six studies that evaluated body weight; three studies that evaluated lean mass; and four studies that evaluated fat mass. There was an increase in the IF group for two studies evaluating weight loss recovery and two studies evaluating post-intervention caloric intake. Most studies investigating ghrelin found a decrease in IF. 19 included studies had a high risk of bias. Three systematic reviews found results similar to those found in this study on body weight change and contradictory results on insulinemia change. There seems to be no difference between IF and DCR in improving most of the parameters studied. |
