OBJECTIVE Studies on the effects of Ramadan fasting on weight changes have been contradictory. [] Key Method All searches were completed between October and November 2011. SETTING Changes in body weight during and after Ramadan were extracted from thirty-five English-language studies and were meta-analysed. Most of the studies were conducted in West Asia (n 19); the remainder were conducted in Africa (n 7), East Asia (n 3) and North America/Europe (n 4). SUBJECTS Healthy adults.
Effects of Ramadan Fasting on Physical Performance: A Systematic Review with Meta-analysis
TLDR
The majority of physical performance parameters were not influenced by Ramadan fasting when tested either in the morning or in the afternoon, and athletes appear able to participate in competition in a fasted state with little impact on physical performance.
Effects of time-restricted feeding on body weight and metabolism. A systematic review and meta-analysis
TLDR
TRF regimens achieved a superior effect in promoting weight-loss and reducing fasting glucose compared to approaches with unrestricted time in meal consumption, however, long-term and well-designed trials are needed to draw definitive conclusions.
A systematic review, meta-analysis, and meta-regression of the impact of diurnal intermittent fasting during Ramadan on body weight in healthy subjects aged 16 years and above
TLDR
RDIF may confer a significant small reduction in body weight in non-athletic healthy people aged 16 years and above, directly associated with fasting time and variably correlated with the season, and country.
Effect of Ramadan Fasting on Weight and Body Composition in Healthy Non-Athlete Adults: A Systematic Review and Meta-Analysis
TLDR
Even with no advice on lifestyle changes, there are consistent—albeit transient—reductions in weight and fat mass with the Ramadan fast, especially in people with overweight or obesity.
Impact of Ramadan diurnal intermittent fasting on the metabolic syndrome components in healthy, non-athletic Muslim people aged over 15 years: a systematic review and meta-analysis
TLDR
It is concluded that among healthy people, RDIF shows small improvement in the five MetS components: WC, SBP, TAG, FG and HDL.
Effect of diurnal fasting on sleep during Ramadan: a systematic review and meta-analysis
TLDR
During the month of Ramadan, there is approximately a 1 hour reduction in TST and nearly a 1 point increase in the ESS score, and effect sizes on sleep quality measures during RDF demonstrated a moderate reduction.
Effects of Ramadan Observance on Dietary Intake and Body Composition of Adolescent Athletes: Systematic Review and Meta-Analysis
TLDR
Continuing training of adolescent athletes at least three times/week during Ramadan observance has no effect on body mass, body composition or dietary intake.
The yo-yo effect of Ramadan fasting on overweight/obese individuals in Indonesian: A prospective study
TLDR
This study showed that dietary factor prior to the fasting has a significant impact on overweight/obese individual and it was found that leptin level at the end of Ramadan was associated with percent body weight reduction.

The effect of fasting month of Ramadan on the abdominal fat distribution: assessment by computed tomography.
TLDR
Despite of the general opinion that supposes the change of weight during the fasting month of Ramadan, there were no significant differences in weight and abdominal fat distribution, however in female and young individuals, there was a reduction in visceral fat compartment.
Effects of Ramadan fasting on biochemical and hematological parameters and cytokines in healthy and obese individuals.
TLDR
Ramadan fasting has beneficial influences on the inflammatory state, as well as metabolic and anthropometric parameters, and levels were significantly lower in both groups compared to pre-Ramadan values.
Body weight loss and changes in blood lipid levels in normal men on hypocaloric diets during Ramadan fasting.
TLDR
Body weight, blood TGs, and high-density lipoprotein cholesterol had decreased significantly, low-density cholesterol had increased, and total cholesterol had not changed compared with base-line values, while the variance in blood lipid levels was explained by weight change through linear and curvilinear regression models.
Study the Effects of Ramadan Fasting on the Serum Glucose and Lipid Profile among Healthy Jordanian Students
TLDR
It was found that high-density lipoprotein (HDL) cholesterol increased significantly during Ramadan, which indicated positive association with pulse rate and fat intake and negative association with systolic blood pressure and weight.
The changes of metabolic profile and weight during Ramadan fasting.
TLDR
This study indicated that Ramadan fasting led to a decrease in glucose and weight, and it seems that the effect of Ramadan fasting on serum lipid levels may be closely related to the nutritional diet or biochemical response to starvation.
Unexpected changes in blood pressure and hematological parameters among fasting and nonfasting workers during Ramadan in Indonesia
TLDR
Results indicate that, regardless of fasting status, blood pressure is lower and RBC production is suppressed in subjects during the Ramadan period, and increased intake of iron-rich foodstuffs is recommendedDuring the Ramadan month,Regardless of fasting practice.
Effects of low-carbohydrate vs low-fat diets on weight loss and cardiovascular risk factors: a meta-analysis of randomized controlled trials.
TLDR
Low-carbohydrate, non-energy-restricted diets appear to be at least as effective as low-fat, energy- restricted diets in inducing weight loss for up to 1 year, however, potential favorable changes in triglyceride and high-density lipoprotein cholesterol values should be weighed against potential unfavorable changes in low-density lipid cholesterol values when low- carbohydrate diets to induce weight loss are considered.
Effects on health of fluid restriction during fasting in Ramadan
TLDR
Common findings of the studies reviewed were increased irritability and incidences of headaches with sleep deprivation and lassitude prevalent, and a reduction in drug compliance was an inherent negative aspect of the fast.
Metabolic, Biochemical and Psychiatric Alterations in Healthy Subjects During Ramadan
TLDR
Although the body mass index remained stable, fasting blood glucose, triglyceride, total cholesterol levels decreased significantly in the study group, and this may contribute to prevention of cardiovascular diseases.
Interactions between leptin, neuropeptide-Y and insulin with chronic diurnal fasting during Ramadan
TLDR
Long-term fasting with interrupted nocturnal eating is associated with significant elevations in serum leptin and insulin and reduction in serum neuropeptide-Y, which appears to be mediated independently of leptin or insulin during this type of fasting.
