Study: Cardio Best to get Your Body to Look Great

Most of all, cardio is great for losing weight. Meanwhile, examples of cardio includes activities like the following.

By the way, seniors who need help walking can use rollators. While these seniors may not get the full benefits of cardio, they will get some benefits by moving their bodies with the help of these devices.

Now, cardio is great for getting significant amount of physical activity, pumping up the heart rate, breathing hard and sweating. Also, cardio is great for burning fat.  And, as it now turns out, a new study points out that the best cardio for weight loss decreases your appetite, which helps you lose weight.  Finally, cardio helps your body look great.

Body Temperature

First, when not exercising, your body temperature ranges between 97.7 and 99.5 degrees Fahrenheit.

Cardio Raises Body Temperature

Second, your muscles contract quicker with cardio such as brisk walking. And, to feed these contracting muscles, your body needs to produce energy. Furthermore, the body gets this energy by burning fat. And, the harder you exercise the more energy you produce. Now, some of the energy, in the form of heat is stored in the body. As a consequence, body core temperature rises by a few degrees. Most of all, during intense exercise your body temperature can spike to 104 degrees or higher.

Hypothalamus Response to Cardio

Third, the brain’s hypothalamus is responsible for monitoring and managing core body temperature. Consequently, the rise in body temperature is sensed by thermoreceptors and forwarded to the hypothalamus.  Now, the hypothalamus responds by trying to cool you down and kicks off a sweat response. Also, it dilates blood vessels to increase blood flow to the skin and warming the surface of your skin. As a consequence, sweat starts to evaporate from the body. And, this evaporation, dissipates heat from the body. Therefore, the body temperature falls.

However, sweat evaporation also causes you to dehydrate. Regrettably, dehydration impairs the body’s capacity to sweat and lose body heat. Consequently, drinking water is essential during an intense cardio.

Cardio Reduces Appetite

Next, recent studies show that rising body temperature causes a decrease in our appetite. And, that this decreased appetite is due to the body secreting fewer of the hormones driving hunger. Consequently, you feel less hungry.

Also, during cardio, body heat goes up. As a result, the brain responds, to this signal, by lowering your appetite.  Incidentally, this is similar to what happens in the body when we eat very spicy foods containing hot chili peppers.

Hot Chili Pepper Analogy to Cardio

Indeed, hot chili peppers cause body temperature to rise and our appetite to fall. Now, chili peppers contain a compound called “capsaicin”. And, “capsaicin” interacts with sensory receptors (TRPV1) in the body. Furthermore, these receptors, bring about a sensation of being hot. As a consequence, “capsaicin” decreases our appetite.

Second Hypothalamus Response to Cardio

Meanwhile, the hypothalamus generates a response similar to the hot chili peppers. By the way, neurons, in the hypothalamus, responsible for coordinating appetite suppression, are called "proopiomelanocortin" (POMC) neurons. Now, these neurons are found in the region of the hypothalamus known as the “arcuate nucleus”.

Meanwhile, the so called blood brain barrier protects neurons from getting in contact with blood. However, some of POMC neurons do come in contact with blood. As a result, they interact with hormones released into the blood and respond to body temperature.

So, heat activates the POMC neurons. As a result, this means the POMC neurons also have TRPV1 receptors. Consequently, heat caused appetite to fall. In conclusion, body temperature acts as a biological signal that regulates feeding behavior just like hormones and nutrients do.


In conclusion, cardio is an effective way to both burn fat and shed some weight by warding off hunger — as long as you’re working up a sweat. And losing weight along with exercising allows your body to start looking much better, stronger, and healthier.
