I remember a couple of witlesses that waddled into the Kingdumb Hell. No, not just the ones that are regular fat. I mean two of them that required special accommodations because they were too fat to sit in a regular chair. One of them required a walker because of being extremely fat.
Now, I cannot judge how much they ate. Some of them have severe chakra or metabolic (or both) problems. People can get very fat eating surprisingly little if their metabolisms have been poisoned by monosodium glutamate or too much soy (soy oil, except lecithin, is also fattening), too much fluoride, high fructose corn syrup, a damaged liver from aspartame or sucralose (aspartame also ruins your brain), or because they are not getting enough iodine. Cutting back on these poisons will "put out the fire". However, not only are they still going to be fat because the fat is there, but their metabolism may well be fxxxed up. These steps will not "build the house back". And diet can aggravate it by slowing your metabolism even more.
Another thing that can result in or aggravate obesity is chakra imbalance. The solar plexus chakra is the one that controls this. If that is working properly, your metabolism and desires for food will be in balance. However, if that chakra is closed, you will be seeking to fulfill your desires by eating too much. Eating while not hungry is a symptom of this problem. Notably, the witless lifestyle where everything is decided for you encourages this particular problem.
Lack of sleep, not getting enough steady exercise, and stress also contribute to the problem. Stress is a major problem within the religion--I think the stress of the religion itself is worse than that of changing religions, even going from being a witless to being a Satanist (though, they add more stress by ruining families for doing this). All these factors are worse among the witlesses because of the ridiculous demands they place on members.
Yet, I have heard scattered reports on people being hounded to lose weight. Not widespread--but you might get a hounder-hounder that thinks you should lose weight. Trouble is, every time you are on the right path, someone else comes along and says that your hours are suffering, or that something you do amounts to martial arts or spiritism (Tae Bo, for instance). Result: You can't lose anything. And they wonder why so many of them go waddling out of the Kingdumb Hells.
