Background/Objectives:Intermittent energy restriction (IER) is an eating pattern of regular daily periods of restricted energy intake followed by periods of unrestricted energy intake. [] Key Method Eight studies that assigned overweight or obese adults to IER or to a DER ‘control’ were deemed eligible for inclusion.Results:All studies reported significant weight loss for IER groups. Average weight loss was approximately 0.2–0.8 kg per week. IER resulted in comparable weight loss to DER when overall energy…
Intermittent versus continuous energy restriction on weight loss and cardiometabolic outcomes: a systematic review and meta-analysis of randomized controlled trials
TLDR
Both intermittent and continuous energy restriction achieved a comparable effect in promoting weight-loss and metabolic improvements.
Intermittent energy restriction for weight loss: Spontaneous reduction of energy intake on unrestricted days
TLDR
Food records from patients undertaking IER suggest a spontaneous reduction in energy intake below their baseline reported intakes and the prescribed isoenergetic diet during all unrestricted days including the days immediately before and after restricted days which contributes to the weight loss success with these diets.
Short‐term intermittent energy restriction interventions for weight management: a systematic review and meta‐analysis
TLDR
Both interventions achieved comparable weight loss of >5 kg and therefore were associated with clinical benefits to health and support the use of weekly intermittent energy restriction as an alternative option for the treatment of obesity.
Efficacy of an intermittent energy restriction diet in a primary care setting
TLDR
Among completers, IER resulted in superior short-term changes in anthropometry and some cardiometabolic risk factors, however, rates of attrition and weight regain were higher compared with standard care, providing important insights in the implementations of IER within a “real-life” NHS setting.
Intermittent fasting interventions for treatment of overweight and obesity in adults: a systematic review and meta-analysis
TLDR
Intermittent energy restriction was comparable to continuous energy restriction for short term weight loss in overweight and obese adults, however, this should be interpreted cautiously due to the small number of studies and future research is warranted to confirm the findings.
Intermittent Energy Restriction Is a Feasible, Effective, and Acceptable Intervention to Treat Adolescents with Obesity.
TLDR
IER is a feasible, effective, and acceptable intervention in adolescents with obesity achieving reductions in BMI and cardiovascular disease risk.

TLDR
It is hypothesize that weight loss from IER could be improved if refeeding phases involved restoration of energy balance (i.e. not ongoing energy restriction, as during intermittent fasting), and possible that achieving energy balance during refeeded phases may be important in realizing the potential of IER.
Effects of intermittent versus continuous dieting on weight and body composition in obese and overweight people: a systematic review and meta-analysis of randomized controlled trials
TLDR
It is suggested that lean mass is better preserved in continuous dieting compared to regular intermittent dieting, and there were no differences in effects for either intermittent vs continuous interventions across all other outcomes.
Intermittent Dieting: Theoretical Considerations for the Athlete
TLDR
While IER—like CER—is known to effectively reduce body fat in non-athletes, evidence for effectiveness of IER in athletic populations is lacking, and theoretical considerations for successful body composition adjustment using IER are provided.
The Role of Intermittent Energy Restriction Diet on Metabolic Profile and Weight Loss among Obese Adults
TLDR
The IER diets are presented as being as efficient as a continuous energy restriction diet (CER) in losing weight and improving metabolic parameters and could present an alternative option for those who cannot accept a constant food regimen.

Effects of intermittent compared to continuous energy restriction on short‐term weight loss and long‐term weight loss maintenance
TLDR
It is indicated that intermittent dieting was as effective as continuous dieting over 8 weeks and for weight loss maintenance at 12 months and may be useful for individuals who find CER too difficult to maintain.

TLDR
These findings suggest that these diets are equally as effective in decreasing body weight and fat mass, although intermittent CR may be more effective for the retention of lean mass.
The effect of intermittent energy and carbohydrate restriction v. daily energy restriction on weight loss and metabolic disease risk markers in overweight women.
TLDR
In the short term, IECR is superior to DER with respect to improved insulin sensitivity and body fat reduction and longer-term studies into the safety and effectiveness of I ECR diets are warranted.
Short- and long-term effects of continuous versus intermittent restrictive diet approaches on body composition and the metabolic profile in overweight and obese postmenopausal women: a pilot study
TLDR
The ID resulted in similar short- and long-term changes in body composition and metabolic profile compared with a CD and at the 1-year follow-up, both interventions were associated with successful and similar weight loss maintenance and improvements in fasting plasma glucose levels.
The effects of intermittent or continuous energy restriction on weight loss and metabolic disease risk markers: a randomized trial in young overweight women
TLDR
IER is as effective as CER with regard to weight loss, insulin sensitivity and other health biomarkers, and may be offered as an alternative equivalent to CER for weight loss and reducing disease risk.
Dietary and physical activity adaptations to alternate day modified fasting: implications for optimal weight loss
TLDR
Findings indicate that obese subjects quickly adapt toAlternate day modified fasting, and that changes in energy/macronutrient intake, hunger, and maintenance of physical activity play a role in influencing rate of weight loss by ADMF.
The effects of intermittent energy restriction on indices of cardiometabolic health
TLDR
Overall, whilst much remains to be learned about IER, including its mechanisms of action and long-term efficacy, the positive findings to date serve to highlight promising avenues for future research.
The effects of modified alternate-day fasting diet on weight loss and CAD risk factors in overweight and obese women
TLDR
Findings suggest that short time ADF is a viable dietary option to help obese individuals lose weight and decrease some CAD risk factors.

It is suggested that ADF is a viable diet option to help obese individuals lose weight and decrease CAD risk.
