I think the OP's theory about getting rid of the weakest link in your body is whacked out and doesn't make any sense.

But I don't think fasting itself is terrible. I know people who fast once in awhile for religious reasons, and it doesn't smurf them up or anything. I DON'T think that depriving yourself when you're hungry is in any way, a healthy way to lose weight. It is a bad bad bad way to lose weight, and any weight you lose will come right back. And maybe even more weight on top of that since people tend to binge when coming off those diets that only last a week or less. IE: fasting, juice cleanse, master cleanse, etc.

As long as you are constantly active, give your body the nutrients it requires. Science has already proven that there are many more negative connotations to this entire deprivation of nutrients. Don't deprive yourself of what its like to be alive and well.
What does your diet look like? When I was eating a lot of carbs, if I went more than a few hours without eating, I would have symptoms of hypoglycemia. Shaking, sweating, lightheadedness, dizziness, intense cravings for sugar.

Ever since I went on a low carb, high fat diet, those symptoms just vanished.

I occasionally do what's called intermittent fasting. It was a by product of my diet and just kinda happened organically, and only after I had inadvertently done it a few times did I research it and found out that it was an actual thing that people on LCHF diets do. Basically, because a lot of my diet was comprised of foods with high satiety, I found thatduring most of the day, I simply wasn't hungry. So I would skip breakfast/lunch and just keep going until dinner time rolled around at which point I would eat cheeses and meats and butter and veggies. Then I just wouldn't really be all that hungry the next day and if I did start feeling a bit hungry, a few nuts or a slice of cheese would fill me right up as a snack.

And during these intermittent fasts from the time I woke up, until around 7PM, I was exercising by running about 2 miles. So I had the energy to do that and felt no negative effects from skipping breakfast and lunch.

That being said, obviously I wouldn't recommend doing that for anyone who ISN'T feeling healthy and satiated. And I would only do this about once every other day, although I didn't really have a schedule. I just ate when I was hungry and tried to abstain from eating or snacking when I wasn't hungry. The weird thing is that sometimes when I'm not hungry, I still want to eat, just because I enjoy the act of eating. Which I think is true for a lot of people. Eating can be a nice distraction, but it's probably unnecessary if you're not actually hungry.
