I recall reading that this is true, but the narrow eating window is believed to contribute to ease of adherence. (No citations on hand, sorry.) My dieting successes have come from both a narrow eating window and lower carb (basically less sweet fruits, and non-root vegetables). Last time I adhered for 40 or so days I hit the wall hard (approx. -10 kg). Zero energy, and miserable. I wasn't sure if it was electrolytes or if I finally found the keto flu (seems a bit late though, and didn't pass in 3 days). So I abandoned ship and have since had no trouble putting 5 kg of fat back on my body. Time to restart!
