Last time I read up on biology, the brain of every human needs glucose as an energy source. So yeah, every human has to eat on a regular basis if they want fuel for their brain to function optimally.

Why does anyone want to fast? Yeah I get it can work, but if your overweight it probably stands to reason that you don't like empty stomachs. Eating healthy is fairly simple.

Nope, doesn't matter. You could eat pure lard, but if you only eat 500 calories of lard per day, you will lose weight just sitting on the couch.

Incorrect. The human brain can metabolize ketone bodies in addition to or instead of glucose.

If you get to the point where you are burning ketones, you are in a world of hurt. Your diabetes is either way, way out of control, or you are desperate enough to try that fat only diet because every anti-seizure medication has failed. Burning ketones is not healthy.

How old school!

It's all about peer reviewed journal articles now.

I can tell you this about nutrition. When I was having severe blood sugar drops twice, three times a week, a medical doctor told me the issue was that I was letting 6 hours go by between meals and that I just couldn't go that long without food.

I would certainly hope a doctor would know what she was talking about when she said my low blood sugar was due to not eating often enough.

And this is something where the knowledge has been around forever. As a teen when I felt shaky and sweaty and disoriented my mother would insist I eat a sugar and a protein, the sugar to feel better immediately, the protein to keep me feeling better. She learned that from my grandmother, who was born in the 19-teens. So the need to eat and what to eat to stabilize your blood sugar has been general non-medical knowledge for close to 100 years.

I just lost a decent amount of weight. A few of the lessons I learned:

- Starvation mode is real. If your calorie in/calorie out is too unbalanced, your brain and body will be convinced there isn't a reliable source of food and your metabolism will slow down.

if Your metabolism slows down isn't it also a good way to save $$$ ? :) As long as You east less calories than You need you should also lose weight and eat less food ($)

I forgot where I read it but I seem to recall a statistic that most people on this earth only eat once per day. This breakfast, snack, snack, lunch, snack, snack, dinner, snack, alcohol daily cycle is pure luxury for most people.

Geoff is correct. Humans can't violate the law of thermodynamics.

The problem is that you don't feel less hungry. In fact your hunger reflex gets stronger and you crave dense foods. Its a survival instinct, if denied adequate calories too long the brain triggers a lot of things to get calorie intake back up while reducing calorie outgo. You just have to spend a couple of weeks convincing your subconscious that food is actually readily available.

Maybe skip the Power Bars... some of them things have more fat & calories than you think. And don't misjudge the amount of calories being burned while biking. It takes discipline and serious change in eating lifestyle habits to drop and sustain significant weight loss.

In my experience, the feeling of hunger presents itself around the time that one would routinely eat. If you eat 5 times a day, and try to fast, you will probably get hungry and stay hungry almost constantly because your body is expecting food constantly. If you settle into a more sparse eating pattern like once a day, your body becomes accustomed to that and you don't get hungry until that time of day that you ordinarily eat.
