About 3 years ago I was able to lean down from my usual 205 lb to 185 lb by running every day and doing a caloric restriction diet using MyFitnessPal. Once I got down to 185 lb, I felt like I lost control of my brain. I became very emotionally unstable, beyond just hangry. I started doing things out of character and doing new things I didn’t usually do. I started to drink more alcohol as well which I had cut down on. Over a couple of months, my weight returned at 205.
Recently, I was diagnosed with osteoarthritis of the hip. One of the only real treatments you can do is to lose weight. I have been doing so and have gone for about 211 lb down to 195 lb. I tried doing a fast starting on Wednesday night. Thursday I did a HIIT workout and after had tingling and numbness in my hands and arms and body. I believe this to either have been a shortage of some sort of electrolyte or possibly ketoacidosis in a mild form. I tried to get some electrolytes and went to bed. About 10:30 that night I woke up and was starving and felt like I had weak emotional control and went and ate. The next day I continued to eat as I determined that I needed to stabilize my body state before trying to fast again. However I noticed I felt a little depressed and I wanted to try new things and I had a very strong urge to have some alcohol. I set up a date with my wife and had a couple of glasses of wine. I went over by my calorie limit for the day by a couple of hundred.
My theory is that hunger not only causes hanger, which has been scientifically proven, but also leads the brain to want to try new things and become more emotionally unstable. I think that this would be an evolutionary advantage, as it is a strong incentive to seek out new food sources when your current food source is reduced.
I see sort of a fundamental basic human instinct when I feed my babies Kate and Griffin. When they are hungry, emotionally they panic and start to scream in desperation.
My theory is that this strong emotional instability and desire for new things when hungry is the factor that drives more people to break their diets than just hunger by itself.
I also believe that a similar principle applies to sex. If a person does not get enough sex, they become less emotionally stable and more likely to seek out new things. I think that this is a big driver of affairs and broken relationships.
I think in many ways people are just little organic machines and if you understand what drives this machines, you can have much better self-control. If you don’t understand your own physical machine, then you’ll be driven by forces outside of your conscious cognitive control.
