Eating is bad for you. Starvation is good for you.
Numerous people around the world fast to no ill effect. In one study, a man fasted for 382 days (yes, that's THREE-HUNDRED EIGHTY-TWO), lost almost exclusively body fat, and had no notable variability in blood values after the first few days. The summary of 60 years of the best research on starvation and metabolism is that after the third day there is only upside until at least day 42 in all participants. To underscore our societal lunacy about eating too much, too often, with too great an emphasis on carbohydrates, Dr. D'Agostino deadlifted 500lbs for 10 reps after a 7 day fast. Read that again and don't ever ever forget it.
We are the descendants of the humans who made it. Our ancestors survived, thrived, grew strong, and in an environment with little food they passed on their DNA to the subsequent generations: us. There are no two ways about it. Eating fewer carbohydrates improves fertility. There is no debate. Ketogenic dieting, whether through food restriction or primarily carbohydrate restriction improves your chances when dealing with hormonal imbalance, cognitive decline and certain cancers.
Now, that's not to say that the cereal companies' marketing and the American agricultural lobby haven't been astoundingly effective at brainwashing the world. They've done a remarkable job at convincing us that we should spike our blood sugar everyday, especially in the morning, and multiple times per day. We know with absolute certainty that this repeated variability in blood sugar increases your risk of all cause mortality. But like cigarettes before them, grains and sugars are hard to kick.
Keep in mind, as noted above, there is absolutely no physical health benefit or physiological basis for an adult to eat every day. Once you're fully grown, there is no need to ever raise blood sugar again. We have this thing you might've heard of: stored body fat. Every single time you eat protein or carbohydrates you signal the body to protect stored body fat. Over time, you become very bad at using stored body fat at all. And if you continue to eat all the time, that's not going to change.
In the modern industrialized world, hunger is a mental illness. All "hunger" is is a word that humans made up in order to describe the unease that we feel when our brain detects a possible or impending gap in the supply/demand equation for the brain. This could be vitamins. It could be minerals. It could be fatty acids. But what the brain absolutely never needs is more external dietary carbohydrates. There is nothing in medical literature to contend this fact. Every study on starvation has concluded that the brain will function optimally with ketones and the glucose that the liver synthesizes. Eating frequently and in large quantities of carbohydrates will increase insulin resistance. When the brain becomes insulin resistant and you are still bombarding it with frequent meals and carbohydrates, what do you think is going to happen? It's called dementia. It's called Alzheimer's. You are hungry for dementia? Yeah, that's mental illness.
Like a smoker who craves cancer, a food addict hungers for destruction of his or her own health and wellness. And so, societally, the time has come to stop with the pretense. Most grown American adults don't need to eat for weeks at a time. We can stop pretending and making excuses. Outside of water, some leafy greens and berries every other day ought to cut it for many nutrients. The rest can be had with a weekly meal of some sort of fish and/or nuts and/or liver from humanely treated grassfed cattle. Not up for real food? Take a multivitamin or greens replacement powder.
The brainwashing is running out of steam; and you are running out of justifications. A man who starved for a week deadlifted 500lbs for 10 reps. An ever-growing number of elite endurance and ultra-endurance athletes are eating zero starches or very low carb. And their performance is improving. What in the world is the layperson doing "fueling the day"? You have fuel for years. It's already stored all over your body. You just have to get good at using the fuel. That starts with opting out of food, one way or the other. It could be a meal. It could be a category. It could be a day or a week or more. But somewhere, somehow, some day you are going to have to opt out. That is the only way. And when you do, you'll be stronger not weaker. You may even lift 500lbs.
