Intermittent fasting not eating for certain regular intervals in order to lose weight has become increasingly popular over the last few years.
The idea is that it helps you expend more energy and burn more calories than you consume, without putting in too much effort.
While not advised for everyone, earlier studies have found that it hassome health benefits, such as improving heart conditions, lowering cholesterol and increasing focus.
But new research is now refuting these claims and stating that you won't lose much more weight compared to the weight you'll lose when sticking to a three-meals-a-day diet.

Study participants
Published in JAMA Internal Medicine, the small randomised clinical trial included 116 overweight and obese men and women between the ages of 18 and 64.
They were split into two groups the control cohort eating a normally structured three meals a day, and those on a time-constrained diet. The latter could eat what they needed between 12:00 and 20:00, but fasted for the rest of the time and were only allowed noncaloric drinks.
The researchers believed skipping breakfast was easier than skipping dinner and did not provide any guidance on calorie intake.
Besides measuring their weight, they measured fat and lean mass; insulin levels; glucose; blood sugar; and energy intake and expenditure during and outside fasting times.

Results
While there was a decrease in the weight of 1.17% in the intermittent fasting group, there wasn't a significant difference compared to the control group that lost 0.75% of their total weight. Most of the loss was also lean mass and not fat mass, which serves as a reminder not to neglect protein intake while fasting intermittently.
They also found no significant difference between the groups when it came to the measured metabolic markers.
The researchers believe easy and straightforward weight loss measures and adherence to lifestyle changes are necessary for health benefits. While intermittent fasting seemed like a good fit, the results indicated otherwise.
"The [time-restricted eating plan] seems attractive as a weight-loss option in that it does not require tedious and time-consuming methods, such as calorie-counting or adherence to complicated diets," write the authors.
"Indeed, we found that self-reported adherence to the [time-restricted eating] schedule was high. However, in contrast to our hypothesis, there was no greater weight loss with [time-restricted eating] compared with the [consistent meal timing]."
