I started planning to write for a different piece of paper – one year after intervention after people who had spent the past year of random 5: 2 intermittent fasting (2 days a week consuming 400-600 calories) in relation to by limiting continuous energy (a characteristic of consuming less per day) that showed that there was no difference between the two, but when I read it I realized that the story was in the initial intervention rather than the aftermath.
Initial intervention involved the random assignment of 332 individuals to one of the 3 dietary interventions: Continuous (daily) energy ban (CER), weekly energy restriction, weekly power cut, and a 5: 2 intermittent fasting pattern comprising 5 days of regular intake and 2 days. very low energy diet every week.
Of the only 146 supplements, no differences were found between diet in terms of weight loss, adherence, lipid conversion or fasting glucose.
And most of them are in line with other 5: 2 IF studies that have found that they are no better or worse than any other approach when it comes to weight loss and biochemical changes. But what is not consistent is the same observation, where other studies tend to see more people give up.
Taking the least deeper into these two things stand out. Adherence was weak for both the CER (49% rejection rate) and the IF (58% rejection rate). But what was different here was the one involved in the CER arm. The women randomized to the CER strand were intended to consume only 1,000 calories a day for one year, while men were intended only for 1,200 calories a day. This is a living low calorie count for those who address and frankly amazed that researchers (and evaluators) thought the degree of continuous restriction would be worth studying.
All of this says that people were just as likely to declare adherence to a misery that caused 1,000-1,200 calories per day as being in a 5: 2 IF approach does not reflect well the pleasing (and therefore widespread) 5: 2 style diets .
And for the inevitable trolleys, I don't hit 5: 2. If you love it, great! Don't stop! But no one expects it to be a panacea for all enemies.
