Healthy Lifestyle Means Better Life

What does a healthy lifestyle mean? A healthy lifestyle is a way of living that results in a healthy mind, body, and spirit. A healthy lifestyle comprises a lot of components: nutritional food good for the body like fresh fruits and vegetables, low-fat diets, unrefined carbohydrates, etc. Eating in moderation is an essential component of healthy eating.

Regular exercise is an important part of a healthy lifestyle. Aerobic exercise is good for your heart and your body. For example, yoga has a therapeutic effect and also helps to reduce your stress level. Pilates is great for strengthening your «core» muscles around your midsection. It is essential that you incorporate any kind of exercises into your daily life to help keep you fit and maintain your weight at a healthy level. Managing stress efficiently is a critical part of a healthy lifestyle. Failure to manage stress effectively can harm your body and affect your relationship with others. If left unattended, stress can also lead to alcohol or drug addiction. Sleeping right, having a positive outlook about life, and having a balanced life are also the necessary components of a healthy lifestyle.  Eating a healthy, balanced variety of foods is far more satisfying. And if you match that with more physical activity, you are more likely to get to a healthy weight and stay there than if you diet.

Are you ready for a marathon of losing your weight? Dieting? Doing exercises? Achieving your goals? Unfortunately, many people who lose weight end up gaining it back. In fact, only about 20% of those who keep diets and who start off overweight end up successfully losing weight and keeping it off in the long term. However, don't let this discourage you. There are a number of scientifically proven ways you can keep the weight off, ranging from exercising to controlling stress.

There are a few calculators that may help you to determine your parameters and make a plan for the future.

BAI and BMI Сalculator

Body image calculators become more and more popular nowadays because they provide objective information about some important indicators we should keep in mind. Body shape index calculators of that kind could give you some basic data about your body condition and prompt that some measures should be taken in case the results are not satisfactory for you. Note that body dimension calculators should consider not only height and weight but also gender and age of people, which is rather important, taking into account the fact metabolism differs depending on these factors.

A great advantage of BAI and BMI calculator is that you could not only find the answer to the question what is a good BMI and bai but also estimate both parameters all together and get more reliable results eventually. BAI calculator is an excellent tool to determine body adiposity index and is helpful for all people who would like to be fit. After you check your body adiposity index with the help of our bai calculator which follows a special bai formula you may find on our website, you could use the guideline table and find out if your BAI is within a healthy body fat level. Many body fat tape measure calculators available earlier required complex mathematical calculations people did not like, but our bai calculator will finish this task in less than a minute.

Our BAI and BMI calculator estimates both your body’s adiposity index and body mass index level and shows the category you belong to: underweight, healthy, overweight, or obese. What is more, just changing the data you insert you may check what the ideal weight for you is and what fat proportion is normal for your age, gender, and lifestyle. This body mass index calculator gives quite a necessary initial result for you to identify if there is any problem and if it’s necessary to do anything with it.

Basal Metabolic Rate (BMR)

One of the important fitness parameters is the basal metabolic rate which could be found through inactive calories. Inactive calories are your basal metabolic rate multiplied by the amount of time that you spend at rest. The amount of time spent on rest becomes less if you spend more time doing exercises, and thus the number of your inactive calories becomes lower.

The basal metabolic rate calculator is actually bmr at rest calculator which counts the amount of energy that is expended at rest in a neutral environment after the digestive system has been inactive for about 12 hours. It is the rate of a person’s metabolism when waking in the morning after “fasting” during sleep. Thus, you may have understood what are inactive calories but some other essential questions are to be considered as well.

So, how to calculate metabolic rate? Why is it necessary? What does bmr measure results could be used for? What is a good bmr? And at last, how to check metabolism and speed it up in case of necessity? All these questions are discussed in this article and will provide you with an in-depth understanding of basal metabolic rate issues. You could also use our basal metabolic rate calculator to get accurate calculations and make conclusions what is the best way for you to act to improve body metabolism.


The best predictor of your basal metabolic rate is your lean body mass.  Maintenance of lean body mass is possible if a person does physical exercises regularly.

Expending extra calories through increased physical activity is the most sensible way to increase metabolism. But when a person keeps a diet, BMR slows down to conserve energy and protect vital organs. A regimen of reasonable dieting with increased exercise maintains or increases BMR and promotes weight loss and weight maintenance. In such a case it mostly depends on calories and caloric balance.

Determining Daily Calorie Needs. Mifflin St Jeor Equation vs Harris-Benedict Equation

Many people would like to be fit nowadays. Some of them clearly understand that good shape may be the result of long-hours’ work only. Others believe that what you need to look slim and attractive is just dieting. One of the most important factors which should be considered by both groups is our basal metabolic rate. You know, chemical processes go on continuously inside our body to keep us alive and our organs functioning in a proper way. The minimum amount of energy our body needs to perform all these functions is called the basal metabolic rate (BMR).

Your metabolism may be partly determined by your genes, although this isn't for sure and hasn’t been proven with 100 percent accuracy. The question how to calculate metabolic rate could be especially essential for those people who struggle to lose weight and who believe that slow metabolism is often to be blamed for them being overweight or even obese. Sounds strange, but some scientific research shows that overweight people have a faster metabolism than thinner people. That’s because larger bodies require more energy to carry out basic bodily functions. Nevertheless, we shall not deny the importance of metabolism for our bodies.

Step one

Good sleep

Metabolism is the highest when a person is sleeping. This means that metabolism is regulated, and thus fats are burned. A night’s unbroken rest allows you to relax well, speed up the regeneration of the body’s cells, and quickly lose weight by accelerating metabolism. You should try to go to bed and wake up at the same time. Try to fall asleep before 10:30 pm and wake up not later than 7 am

Step two

Moderate physical activity

In order to lose weight, calculate calories, and have at least moderate-intensity physical activity. The latter doesn’t mean many hours in a gym. You could go on foot, try swimming or jogging, do morning exercises. Moderate activity will help you keep your body strong and young, increase immunity, become stress-resistant and always have a positive mood

Step three

Drinking enough water

All nutritionists of the world say that in order to maintain the beauty and health of our body, at least 2 liters of water must be consumed.

The drinking regime will make it possible to lose weight more intensively and improve your skin

Counting the daily calorie rate, the proportion of proteins, fats, and carbohydrates, as well as calorie content of foods, allows you to make an ideal diet for you, in which you will lose weight (or keep in shape), eliminating any health risks. A competent menu will make it possible to control the supply of all the elements and vitamins essential for your organism

Step five

Quiet mind

The key to health and a beautiful body is a calm, reasonable, sound mind. To stimulate brain activity both proper nutrition and moderate physical activity are necessary. Some special techniques like meditation and yoga that would help you to get rid of negative thoughts are to be considered as well. You will remain calm, composed, and steadfast to the main purpose. Storms, emotions, and crises would come and go, and you will keep a cool head

Step six

Healthy environment

Avoid people who suck all the positive energy out of us to fuel their relentless hunger for negativity, leaving us drained, exhausted, and unhappy.
