Intermittent fasting has similar effects to calorie-restricted diets in terms of weight loss, concludes a meta-analysis, published in The BMJ, pooling the results of 99 previous clinical trials. Of three types of intermittent fasting (alternate-day fasting, time-restricted eating and all-day fasting), intermittent fasting has a higher impact on weight reduction compared to continuous energy restriction, the study adds.

In a group of people at high cardiovascular risk, low to moderate wine consumption was associated with fewer cardiovascular events (cardiovascular death, myocardial infarction, stroke or heart failure), according to a study. The analysis uses urinary concentrations of tartaric acid, a substance found in grapes and grape derivatives, as a biomarker of wine consumption. It finds that consuming between three and 35 glasses per month was associated with fewer cardiovascular events than in people who consumed fewer than three or more than 35 glasses. The study, published in the European Heart Journal, included more than 1,200 participants from Spain's PREDIMED study with an average age of 68 years.
