You will be doing your body a favor on the long term provided you have access to a variety of foods, having a reserve of such for quick replenishment when actually needed. For man is designed to regularly deplete reserves before replenishment, as beginning with the fall of man and until relatively recently, most people had to plant, harvest and or raise and kill what he would eat, versus having a refer full of food and eating for pleasure more than actual need.
The difference is that today we usually have a variety of foods=better nutrition accessible for replenishment, but with the downside usually meaning that, with the reduction of physical exercise, most of the West is overweight (72% in the US) and even obese (42%) which is far worse than not having a reserve of any kind for an emergency, providing access to a variety of foods is available. Obviously, if doing something like hiking a long trail, then loading up is normally advisable.
However, not everyone's metabolism and health is the same, and may God help you in your situation.
BTW, a high fat/low carb near-carnivore diet has also improved my ability to put on and keep muscle. Over the last 3 years, my weight has remained steady while my fat has been slowly going away. It looks like I’ll be genuinely slim - not “ripped”, which is unhealthy, but slim - and weigh around 155-160 at the end. But with muscle replacing the fat.
I’ve gradually moved from “keto” to “near carnivore” and eating one meal and a snack for each day. I’d prefer OMAD - One Meal A Day - but I just can eat enough during that one meal!
Still, slender with muscle at 160 will be vastly better than scrawny yet FAT at 120!
