They spend a lot of money on the gym, follow different diets to lose weight, and in maintaining a healthy lifestyle. The one product that helps lose weight is found in every household. That product is caffeine. Many of us around the world start our day with tea or coffee. Did you ever think why? It is because of caffeine in it. Caffeine instantly makes you feel refreshed and active when you woke up. Caffeine is a natural product obtained from some seeds and plants. Cocoa beans and coffee are the most common sources of caffeine. However, it can also be produced in chemical laboratories to be used in different products. Caffeine is a stimulant and known to be the most consumed psychoactive drug. It is often found in different beverages such as tea, coffee, cola, etc. How does caffeine work in your body? It stimulates the brain and nervous system and increases their activity. Besides it also activates the heart and blood pressure muscles.
Caffeine and fat Burn
Several research shows a significant relationship between caffeine and weight loss. It also contributes to appetite suppression i.e. loss of hunger or desire to eat. However, the most talked-about function of caffeine is its role in burning body fat. There are two types of fat in the body one is a healthy fat that is required by the body and the other is non-healthy fat not needed by the body. The unhealthy fat is stored and needs to be released to be removed from the body. In this article, we are also going to discuss the same function that how caffeine helps in burning fat. But before that, we must understand that burning fat doesn’t mean melting it down or heating it. To burn fat means to use fat for energy. However, fat can only be converted to energy in the form of fatty acids. You lose body fat when Fat cells or adipose tissues which stored the fatty acids released them into your blood. One way to release these fatty acids in the body is through caffeine. When you take coffee or tea the caffeine in it breaks down the adipose tissues. The fatty acids stored in tissue are freed and entered into your blood to be used for energy. This is done through lipolysis, a process that increases the level of hormones epinephrine and norepinephrine in your blood. These hormones then signal the fatty acids to be released into the blood.
Caffeine and metabolism
Though fatty acids are released in the blood that is not enough. These fatty acids are needed to be burned so to be used for energy. The burning is done through metabolism. The more metabolic rate the more increased in fat burning rate. The metabolism rate of your body depends on your lifestyle, genes, and diet. The one substance that can stimulate metabolism and increase metabolism rate is caffeine. For that reason, Caffeine is found in fat-burning supplements as well. Caffeine initiates thermogenesis in your body that generates heat to burn calories. The research found a 29 percent increase in the metabolic rate of slim people by using caffeine. However, it showed fewer results in people with obesity which is about 10 percent only. Another study identified the significant effect of caffeine on certain genes that activated the metabolic rate of the body.
Caffeine and exercise
Exercise is the best way to burn calories. Besides it also prevents us from various diseases and maintains overall health conditions. Moreover, by doing exercise you feel energetic and boost up. Other than that exercise refreshes the mood, helps in better sleep and contributes to fighting depression and anxiety. Science has proved that exercise burns fat faster and also improves the composition of the body. You cannot lose weight or burn fat by just having supplements. For that, you have to move your body to increase blood circulation. One compound that can enhance your exercise to a greater level is caffeine. It acts as a fuel that charges the body to perform better. Caffeine is ergogenic which means it pushes the exercisers to perform better and harder. It also turns on the fat-burning activity by releasing fatty acids. Caffeine also charged your mood and activates energy so that you don’t feel lazy during your workouts.
Although caffeine aid to exercise not all types of exercises get benefit from it. Several studies tested the effect of caffeine on different types of exercise. The first is Endurance training; it involves physical activities that increase your breathing such as running, jogging, cycling, swimming, and others. The research found positive effects of caffeine on athletes involved in physical activities and sports. The second category is strength and resistance. It involves those activities that enhance your muscle movement such as weight lifting. It also helps in increasing the strength and size of the muscles. The research found no significant effect of caffeine on this set of exercises. Another research reported that caffeine is more helpful for trained athletes than untrained ones. So it is concluded that caffeine works only for high-intensity exercises.
Even though caffeine showed positive results in burning fat and losing weight but the effect may not last for the long term. This is because people may develop tolerance towards the effects of caffeine by consuming it on regular basis. However, it may help you in eating less by suppressing your appetite and desire to eat.
SIDE EFFECTS OF CAFFEINE
Although caffeine plays important role in losing weight its consumption has some dangers as well. People should be cautious while taking caffeine products and consume them in moderation. Over-dose of caffeine can lead to several diseases. The major side effects of caffeine are insomnia, anxiety, dizziness, increased heart rate and blood pressure, stomach problems, etc.
Professionals recommend that people should take less than 400 mg of caffeine in a day. In conclusion, to maintain your health it is important to keep both benefits and side effects of caffeine in mind.
