"We always thought that fat (acting as insulation) was the most crucial factor in thermoregulation, but it's actually muscle playing the vital role. The body is this amazing, dynamic system which uses muscle to generate heat to keep the rest of the body warm, including your hands."
Men tend to have a greater muscle mass than women which helps them to generate heat. Even at rest, your muscles produce around 25% of your body's normal temperature, so more muscle mass means a greater heat production.
Muscle conducts heat a lot better than fat! There are more blood vessels moving through muscle than there are through adipose tissue. Therefore the heat transfer is easier. It's the same in humans.
Studies have shown people who have a larger amount of fat in the body may feel warmer than those who are leaner. It is because the extra fat is said to heat up the body, since it acts like an extra layer of clothing.
No. Skin sensations of cold or heat don't change as far as your percentage of body fat. A higher percentage of body fat does provide more insulation so one with a relatively high percentage of body fat will maintain their core temperature for longer in a cold environ.
Cold intolerance can be a symptom of a problem with metabolism. Some people (often very thin women) do not tolerate cold temperatures because they have very little body fat to help keep them warm.
If you are relatively fit and seem to "run hot," there's an explanation for that: Muscle tissue generates heat, offering a different protection from the cold. If you're relatively petite, not only does a low BMI heighten your response to cold, but so does your overall surface area.
You might feel colder.
"Your body is going to lower your metabolic rate when you lose weight to try to conserve energy," Apovian said. "And in conserving energy, it doesn't have a lot of extra calories to keep you warm." Another reason you might feel colder is because you no longer have fat acting as an insulator.

Although men and women maintain an internal body temperature of 98.6 degrees, men typically have more muscle mass and generate more heat by using more calories to fuel those extra muscles. When that heat evaporates, it warms up their skin, their clothes and the air just above the surface of their skin.
Human body temperature is inversely correlated with body mass.
People who exercise often increase their metabolism, thus raising their body temperature.
Summary: New study suggests that people with more muscle mass are less susceptible to heat loss and heat up faster after cold exposure than non-muscular individuals.
Studies show that in winter, testosterone levels naturally decrease and estrogen levels elevate slightly. This makes it a bit easier to add body weight, both fat and muscle.
Using cold showers (cold water immersion, or CWI, in research), long-term, will attenuate the anabolic signaling that occurs in muscles2 through the reduction of inflammation. I.e., you will decrease your ability to build a maximum amount of muscle, which directly contradicts the goal of building muscle.
Thin people's subcutaneous layer lacks adipose tissue, but fat people's subcutaneous layer contains adipose tissue, which functions as an insulator and keeps the body warm. As a result, thin people feel colder than fat people.
Lastly, studies have suggested that obese patients tend to have a lower core body temperature than leaner individuals, which points to significant metabolic changes as body fat levels increase. In short, don't assume that just because someone is overweight that they feel less cold than their slimmer counterparts.
Some other signs of fat loss are:
It leads to a slimmer appearance and more muscle definition. Your exercise stamina increases, and you are getting fitter. As a result, your physical activity level shows improvement. You don't feel any energy slump in the afternoon and experience a better mid-day energy level.
Because heat production is linked to exercise intensity, your body heats up more quickly when you are fitter and needs to become better at cooling itself to cope with this demand.
Cold intolerance is a frequent complaint among those who have lost a considerable amount of weight. The body's core has lost a significant part of its protection against heat loss. The problem is usually worse for those who become very thin, especially small women.
Even when bodies are the same size, the amount of body fat inside can vary — and affect how cold or hot we feel in comparison to others. The greater the amount of body fat, the warmer one feels. Older people often might feel colder than younger people, as the fat layer under the skin that conserves heat thins with age.
When you're exposed to cold temperatures, you might notice your feet and hands are the first to get cold, but your chest and torso are still warm. Since your feet are furthest away from your heart, it can take longer for your blood to circulate through the limbs of your body.
The good news: Not only will your body acclimate to the cooler weather, but you can also hurry this process along. Beginning in the 1960s, U.S. Army researchers found that nude men who spent eight hours a day in a 50°F (10°C) chamber became habituated to the cold and had mostly stopped shivering after two weeks.
Some people naturally tend to feel colder than others without any discernible cause. However, cold intolerance can also indicate an underlying medical condition, such as hypothyroidism, anemia, or peripheral artery disease.
The fact that women have muscles is as natural as breathing; for many men, this is the most attractive feature of the female body. Men adore a body that can support a strong personality. They are especially attracted to strong, capable sexy bbs and muscular women.
