You’re wrong an a lot of accounts.
Metabolism is a big factor. You say it depends on calories in vs calories out, agreed. What do you think determines how many calories in/out? You guessed it, metabolism. It’s not just an excuse and does affect people, endomorph, ectomorph etc.
As for it’s role in diet, bodybuilders, people who put all this theory to practical use and get their body fats down to 5% etc, recommend that you eat every three hours. Little bit at a time, to keep your METABOLISM working. If you go the quick rout and stop eating, your body goes into starvation mode and starts burning muscle or fat, whichever is more plentiful. It also starts holding fat because it thinks there is a shortage of food, which made sense thousands of years ago when food wasn’t available at the nearest grocery store.
Quick diets don’t work, hence the name, “yo-yo” diets. People lose weight, gain weight etc. Slow, methodical diets work, the only problem is people don’t fully clean up their diets and don’t do enough cardio. I’ve heard of women complaining about not losing weight and they eat chocolates etc and consider walking enough of a workout. Go look at how a bodybuilder diets. They’re not trying to lose 5 lbs, they’re trying to get shredded. I personally know a guy who was kind of chubby in high school and he started bodybuilding, follows the principles of keeping your metabolism going, dieting slow and steady, and he gets absolutely ripped for his contests. These guys diet over a few months to get to their desired weights.
And before you respond, go visit bodybuilding.com and read the articles on nutrition by nutritionists, trainers etc who are world renowned. These people train professional athletes as well. Again, these are people who put this stuff to use and their livelihoods depend on it, I seriously doubt you know better than them. canadiandesigirl is studying this stuff as well and she’s just stating what I’ve read about nutrition and weight lifting.
Now that said, can someone lose weight quickly by just not eating for a week. Sure, you’re going to lose some weight for sure. But guess what? Your body is now carb sensitive and as soon as you start eating, up go the pounds.
If you’re right, then thousands of athletes and bodybuilders around the world have been doing it wrong for years.
I just saw your response and you seem to be talking about weight loss period. I agree, you can lose weight by not eating, but you will also lose muscle, which is wasting your hard work. And again, the weight will come back quickly as I discussed above. And that is definitely not healthy for your body. So it’s possible, but not healthy or sustainable.
