Yep different people process different food different ways
it's still a good rule of thumb...
Food value, is different than just straight calories...
You could live on salt & sugar, empty calories but for how long ?
What's the longterm ramifications ?
What you did as a young person vs an older adult, not as active
Like my dad, alcohol cardiomyopathy and heart disease,
quadruple by-pass, valve replacement/pig valve, asthma/COPD,
hardened arteries, clogged arteries, heart attacks, can't breath,
now both corraded arteries are 70% blocked, yet another surgery
& many, many lingering health issues...
He lived literally off red meat & chips, junk food & booze,
it all has calories, and counts the same right ?,
he's thin, with very lil' muscle too...
But;
I ain't doing that, nobody should...
All of it because of what you/he consumes...
Not all food is the same...
I may fill the hole, may make a turd, but it's not just plain calories...
Food or
good nutritious food is usually, less calories & more fiber too
you can 'many times' eat more of it to feel full, larger portions,
it doesn't taste as good usually too...
if you live off a high-fat & high glucose/processed food diet
you probably won't live as long too...
That's a fact...
Water is life too...
That's another fact...
I love veggies & fruit...
I also love pasta/some bagels/breads/biscuits/sweet cornbread (Carbs),
meat & potatoes (that's how I was raised),
cheeses, ribs, burgers, hotdogs, pretzels, ice cream
(I love most of it but don't eat much of them now)
Occasional beer/drink (rarely now too)
Empty calories galore, some of that, it
may feed you yes it may/will fill your belly
but some of
it is not very nutritious, but it fills you up, adds bad calories too...
Not as healthy for you either...
What's the old adage (almost) anything in moderation...
Eating the higher protein & more roughage, fruit & veggies
not consuming as many calories PERIOD !!!
Your body will start to consume the 'fat storage' you have...
Something
fat people have a problem with,
many why they do overeat, especially sugars & carbs,
consume cokes/booze/beer overboard
they want that full feeling, sugars & carbs give them...
