Drinking coffee to lose weight, good or not?

Nowadays, many people drink a lot of coffee every day because they think that drinking coffee to lose weight is very effective. Is this method excellent and safe for the user's health? Let's join us to answer the above question through the following article.

Drinking coffee to lose weight, is it true?

The trend of drinking coffee to lose weight was introduced and became popular in the book "The Coffee Lover's Diet" by American author Bob Arnot. According to him, drinking coffee many times a day can increase metabolism, burn fat, prevent calorie absorption, and reduce appetite. Specifically as follows:

Reduce appetite

Some studies show that if you drink coffee right before eating, it will limit appetite and reduce calorie consumption. However, few people do this, most have the habit of drinking coffee about 3 - 4.5 hours before eating. At that time, the way to drink coffee to lose weight does not seem to affect the amount of food you take in.

Stimulate metabolism

Coffee actually can increase metabolism and promote the burning of calories and fat in the body.

Impact on fat cells

When drinking coffee to lose weight, caffeine will increase the concentration of epinephrine (adrenaline) in the blood and stimulate the nervous system to send signals that directly affect fat cells. This will promote the breakdown of fat and release energy into the blood. However, the process of releasing fatty acids into the blood will not help you lose weight if you do not burn more calories than you take in.

Harmful effects of using coffee to lose weight

Before applying the method of drinking coffee to lose weight, you need to carefully consider the possible harmful effects:

Coffee has too much caffeine

Drinking coffee to lose weight can increase metabolism largely thanks to the caffeine content. However, if the amount of caffeine in the body is too large, it can pose many health risks such as heart attack, headache, insomnia, high blood pressure, osteoporosis, or even depression.

The reason is that caffeine is also a diuretic, so it will make you go to the toilet more often. At that time, many important electrolytes such as potassium and calcium will be lost along with the amount of urine excreted. Too much potassium loss will lead to hypokalemia, affecting muscle control and heart function.

Coffee makes weight gain easy to return

The truth is that it is very difficult to lose weight if the diet requires a significant reduction in calorie intake such as drinking weight-loss coffee. At that time, the body will switch to survival mode, slowing down the metabolism, and thereby reducing the amount of calories consumed. Not only that, hormonal changes will reduce the amount of leptin hormone (which plays a role in promoting the feeling of fullness and sending signals to the brain to stop eating). You will crave food and if you cannot resist, the result is weight gain again as before.

Not safe for health

From the above analysis, it is easy to see that drinking weight-loss coffee is not a safe method. On the contrary, it also has many potential risks to the user's health.

Instead, you should apply a scientific, healthy diet, with lots of green vegetables, and fruits, drink lots of water, and combine with regular exercise. That is the safest and most effective weight loss method.

Everything you need to know for beginners in Brazilian Jiu-Jitsu

Observation - the first lesson before deciding to study Brazilian Jiu-Jitsu

Before starting to practice Brazilian Jiu-Jitsu, especially for the first time, it is best to learn the basics of this subject thoroughly. Each martial arts school has different characteristics, although the curriculum does not have many differences. Before registering to study BJJ, spend a lot of time carefully observing other students to better understand the subject and decide whether BJJ is suitable for you or not.

Observing the coach and other students practicing will help you clearly visualize the class, and prepare questions for the coach so as not to be surprised.

What to prepare on the first day?

On the first day of class, wear clothes that absorb sweat well such as shorts and t-shirts. You should buy a separate Brazilian Jiu-Jitsu uniform, absolutely do not wear street clothes or shoes in the gym, which will easily scratch the floor. Drink enough water and have a light meal before practice to avoid losing energy. BJJ is a sport that requires high endurance, bring a water bottle if the gym does not have a drinking water system.

The curriculum in each place may be different, but here are the general notes you need to know:

• Warm-up: The purpose of the warm-up exercise is to "warm up" the muscles before practicing, avoiding injury. It can be warmed up for a few minutes or longer. All martial arts classes start with group warm-up exercises such as jogging, push-ups, etc.
• Technical exercises: After the warm-up exercise, you will be paired with a training partner and practice in an area on the floor. The coach may go through a lot of moves with quite new and complicated names and techniques, so don't hesitate to practice again and ask questions to avoid practicing the wrong techniques and getting injured.
• After practice: At the end of the class, the coach will bow to the students traditionally, thank everyone for participating, and encourage the students' efforts. Besides, you can join Dynamic Stretching classes after practice if you want to completely relax your body.

After taking a shower, make sure your body is fully hydrated and well-fed. If you want to understand more about the course, don't hesitate to discuss with the coach about the next program and other martial arts classes, discuss prices, and set up a clear schedule with the instructor.

Important notes

After practice, take the time to shower first, drink water, wait 20 minutes, and then start a meal to replenish energy. BJJ classes include classes without Kimono for beginners (No-gi) and advanced classes with Kimono (Gi). Depending on your physical condition and experience in martial arts and participating in sports, consult the instructors or choose the most suitable class for yourself.

The spirit of BJJ is quite similar to Judo, using Softness to overcome Hardness, using flexibility to defeat violence.
