The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
Over six months, both groups of women lost about 8% of their initial body weight. And both groups had improvements in glucose regulation and other health indicators. But the women on 5:2 intermittent fasting had a greater improvement in insulin sensitivity and lost more belly fat compared to the group that was counting calories, if you will, every meal.

So, I mentioned the study with Michelle Harvie in England. That was really, we dissociated. Remember, we had a group that was counting calories each meal, and then we had group 5:2 intermittent fasting. And they both lost the same amount of body weight, and over six months, their calorie intake was the same. Yet the women on 5:2 intermittent fasting lost more belly fat, and had a significantly greater improvement in insulin sensitivity.
