When your not digesting anything your body goes into a catabolic phase, which basically muscle degeneration when your body starts literally canabalizing on it's own body for fuel, and once your body hits a lower body fat %, your body's preferred choice becomes breaking down muscles.
Eating small meals frequently encourages anabolic phase which is great to stimulate muscle growth. Why you shouldn't over eat to point of being full is because when your full, your body routes excess blood from the rest of your body to your stomach to help speed up digestion, but it also slows down body functions everywhere else.
A good example is like a restaurant prepping for a busy night, once some shipments come in, the boss will probably ask everyone to help unload, and after it's done he'll let you go back to whatever you were doing.
One thing that many people don't realize is that if you eat say a pizza at 2,000 calories for the entire pizza. If you eat the whole pizza in 30 minutes will actually do your body less harm than eating the whole pizza over a entire day.
A good example of this is people that are so obese they can't even move out of bed, I've seen documentaries about people who eat 20,000 + calories a day, since 3,500 calories = 1 pound of fat techically they should've been gaining 5.7 pounds a day. But there is a limit on how much you can digest and absorb.
This is because the body has a limit to how much it can process at a time. If you overload your body all at once, much of it will actually go down the toilet literally.
Your body can store excess calories, but it can not store excess protein, so make sure you get some sort of protein every 2-3 hours.
The key of dieting is to keep constantly fed but never to the point of being either hungry or full. When your body is feeling hungry NEVER EVER AVOID A MEAL. This sounds strange since there are many things on the market that sells well like appitite surpressants.
but only reason why those really work is that if you don't fuel your body correctly, your body resorts to taking the fuel from your own body. This might not sound bad, because people think they'll lose weight, which is true and they will.
But this doesn't mean it's a good idea or healthy at all. Mainly because your goal should be to lose BODY FAT, and not WEIGHT. In my opinion, anyone who relies solely on a scale as their measurement of progress, should also hold this sign as they weigh themselves.
This is because there are wayyyyyyyyyyyyyyyyyyyyyy too many factors to rely on a scale alone. A good example is say you weighed 120 in highschool, and after school your metabolism took a dive in your 30's and you started eating bad. Now your upto 150. So you want to lose that 30 extra pounds through good diet and exercise. Now also remember that muscle weighs more than fat, and when you workout you WILL create more muscle. So now that goal of 120 is a goal that you might never reach.
Many people get so fixed into hitting that goal towards the last 5-10 pounds when they get "stuck" at a good weight they keep pushing with a harder dieting plan, or upping their workouts or even both. In efforts to reach their "goal" This kind of goals are set by people who don't know any better. Everyone at one time or another have always made this kind of mistake.
Better methods of measuring progress
1. Pair of jeans, the looser it gets, it will show amazing amount of progress
2. before and after pictures, especially if you can take 1 every day in the same position.
3. body fat calculators (omron about $30 at target and walmart tend to be the most accurate)
Also remember with body fat analyzers that there are also MANY variables, remember to only take your reading at the most consistant time. After you wake up, after you use the restroom, taken a shower, dried off completely naked to first weigh yourself, then use the body fat analyzer to measure your body fat % . You'd be surprised fully clothed can easily add an extra 5-10 pounds onto the scale.
*if you get bored or wanna show off you can bring the body fat calculator to the gym and measure yourself after a tough workout. After all the sweating and dehydration, not to mention having the pump through your body these will change the readings dramatically lol.
If you hit the gym and ran 2 miles, then hit the weights tense up all your muscles and use it, I got as low as 6% LOL, even though I'm normally around 10-12% lol, it's just for fun mind you JUST FOR FUN!!!!
