The problem with routinely skipping dinner is getting enough protein. No matter how much protein you eat in one sitting, your body can use at most 40 or 45 grams. (The rest is converted to fuel—glucose, fructose or fatty acids, I don’t know which.) On a low protein diet, it is difficult to maintain anything near an optimal amount of muscle mass (even if you train regularly with weights) -- and the older you get, the harder it gets. One thing muscle mass is good for is smoothing out spikes in blood glucose: the muscles remove glucose from the blood and store it. Muscle also protects you from injury. Also men report that people (men and women) seem to like them better when they have more muscles (within reason).
But yeah, if you don’t have to worry about maintaining muscle mass, routinely skipping meals (“time-restricted eating”) is a very easy way to maintain a healthy BMI.
The upshot is that the studies saying your body can only use 45g of protein per meal for muscle synthesis are mostly based on fast-acting whey protein shakes. Stretching out the duration of protein metabolism (by switching protein sources and/or combining it with other foods in a gradually-digested meal) can mitigate the problem quite a bit.
