Have you read the paper at all? The actual title contains this: "Time-restricted eating with or without low carbohydrate diet". Look at the "with or without" part.

I read the title and looked at the graphical abstract. :)

You’re right in that the LCD did not seem to improve MetS (the focus of the paper), but it looked to me like there were benefits to combining fasting with low carb, i.e., weight went down more.

The graphical abstract seem to indicate that low carb combined with time restriction gave better weight loss results in addition to all the other benefits of time restricted eating.

Did I read the graphic wrong or does paper not match the graphic?
