Men tend to have more muscle than women, and because muscle burns more calories than fat, men tend to have a faster metabolism, too — anywhere between 3 to 10 percent higher than women, studies have shown.

Fat doesn't burn ANY calories. MOVEMENT causes calories to be burned.

KNOW THIS:
1. The first 20 minutes of cardio activity (brisk walk) NO fat can be burned. None, zip, zero. The fuel for that first 20 minutes is CARBOHYDRATES (CHO). They MELT the fat as one walks. Hard fat (lard) HAS to be liquified to be able to be used as fuel. If you are going to sautee onions in lard, the lard has to be melted first to be useful for sauteeing the onions. Our fat is the same way: must be MELT/LIQUIFIED to be used as fuel for exercise.
2. 20-30 minutes of cardio = the rest of the CHO are being used as fuel for the muscles and SOME fat is liquified and used as fuel for movement.
3. Longer than 30 minutes = 100% fat, liquified, is the source of fuel for the body. Thus, ALL fat is being burned from 30 minutes on.

*Some people try to "fudge" on this and their "one-hour" walk is done in 20-minute increments. Lol. Fudging works with people but not pounds. The walking HAS TO BE CONTINUOUS...not fast, just CONTINUOUS.
**SOME people think: I'll NOT eat and then walk for a long time. Hah! Doesn't work.
If there are NO carbohydrates to MELT the fat then the body turns to MUSCLE to melt the fat. Stupid move, folks. One is "robbing Peter to pay Paul." If one does that then the muscles deplete SUPER FAST because they are moving the body AND being made to melt the fat to used it as fuel.
USELESS and counterproductive!

=============================

Men "TEND" to have...LOL. Men and women have the same 650 muscles in the human body. Men have more strength with those muscles because they are LOADED with testosterone. THAT hormone makes their muscle fibers thicker, bigger and thus stronger.

LIFESTRONG (Internet)
Men had an average of 72.6 pounds of muscle compared to the 46.2 pounds found in women. The men had 40 percent more muscle mass in the upper body and 33 percent more in the lower body.

Strength Translation
Men not only have more muscle, but pound for pound, their muscle is slightly stronger than a woman's -- about 5 to 10 percent, says Lou Schuler in "The New Rules of Lifting for Women."

A study reported in a 1993 issue of the "European Journal of Applied Physiology and Occupational Physiology" attributed this strength difference to larger muscle fibers in men.

From Wikipedia:

Testosterone is a steroid hormone from the androgen group and is found in mammals, reptiles, birds and other vertebrates. In mammals, testosterone is secreted primarily by the testicles of males and the ovaries of females, although small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid.

In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate as well as promoting secondary sexual characteristics such as increased muscle, bone mass, and the growth of body hair. In addition, testosterone is essential for health and well-being as well as the prevention of osteoporosis.

On average, in adult males, levels of testosterone are about 7–8 times as great as in adult females, but, as the metabolic consumption of testosterone in males is greater, the daily production is about 20 times greater in men.

I have never heard of carbs needed to burn fat, what can I read to get more info

Thanks for the good information!!!!

And yet the bogus Body Mass Index insists that men and women should be of identical ideal body weight to height regardless of the composition of that "weight".
