If you’ve just started and already feeling lowered hunger signals then you are very lucky, some people don’t get that for weeks or even months. One of the BEST things you can do to spur rapid weight loss is to increase the temporal distance between your meals. That’s why so very many people here do a form of intermittent fasting. Keto makes them less hungry, which in turn allows them to space out their eating further, which in turn spurs more rapid lipolysis.
So absolutely, if you aren’t hungry, feel free to skip a meal. All those extra hours with your insulin lowered is more time that you body is eating through your own fat.
If you can avoid it then don’t snack at all. It’s much better to have larger meals spaced further apart than a similar amount of food more distributed over the same time frame. The latter just leads to a higher overall insulin and less fat loss.
