People talk about their metabolism a lot. You'd think they actually understand it. But often that's not the case. Here are four things you should know about the M-word:
Burning Truth No. 1: Skinny People Have Fast Metabolisms
VERDICT: Sometimes
"There are slim people with slightly low metabolisms who just don't eat very much," says Michael Jensen, M.D., an endocrinologist with the Mayo Clinic. "And there are heavy people with really high metabolisms who eat a huge amount."
Burning Truth No. 2: Lean Tissue Burns More Calories Than Fat Does Even While You're Asleep
VERDICT: True
"Your brain, heart, liver, and kidneys use a lot of energy, even when you're lying still," says Dr. Jensen. Muscle and the GI tract don't use much at rest; fat burns practically nothing. His estimate: You burn about a calorie per minute at rest. A quarter of that is torched by muscle, and 1/50th of it is burned by fat.
Burning Truth No. 3: Some Guys Can Only Slim Down By Slashing Calories
VERDICT: False
"In 30 years I've never seen anyone with a truly low metabolic rate," says Dr. Jensen. "People who think they need an 800-calorie diet often have resting metabolic rates of 1,500 calories."
So why can't they slim down? They're often eating many more calories than they realize. His fix: Accurately record everything you eat for two weeks. Unhealthy trends may emerge.
Burning Truth No. 4: Cutting 500 Calories A Day Means You'll Lose A Pound A Week
VERDICT: Not Quite
A pound of fat does equal 3,500 calories, and you may lose a pound the first week. "But when you eat less, you lose lean tissue, so your basal metabolic rate goes down," says Dr. Jensen.
Surprise: You may gain more than a pound after a 3,500-calorie pig-out, since calories stored as sugar cause you to retain water.
MyAchingKnees Comment: You can spend your time trying to figure out Metabolism rates, what foods may increase it, and what doesn't. You can try the latest fat burning tablets from the local pharmacy. Or you can just accept that diet and exercise, minimizing the bad foods you eat and increasing your physical activity is the most assured way to lose weight.
If you try some of those well advertised diet plans out there just be aware that most of these diets fail because they do not provide the nutrients your body needs. That's why some people get sick during their diets as their immune system is depressed from the lack of nutrients, and that's why some people gain weight after the diet as they are nutrient starved when they come off their diets.
