Fat and Cholesterol

What is metabolism and what is a calorie?

Nutrition is the provision of the nutrients (materials in the form of food that are necessary to support life) to the human body. It contributes to health, beauty and longevity.What is energy?
The ultimate source of energy is the sun. This energy bounds in plant chlorophyll. Then animals eat plants so the energy is saved in their body. Our food is consisted of plants and animals, so we eat in order to provide ourselves the energy that is needed for our activities. Energy is available in our body in two forms: potential and stored. The potential energy is available in the process of metabolism. Energy that is stored in our body has the form of the glycogen.
What is a calorie?
We use calories as a unit of food energy. They come from nutrients, proteins, carbohydrates and fats. Vitamins, minerals and water do not contain calories. When we eat, our body separates the nutrients from the food and turns them into glucose. Part of it is burnt because it’s the direct source of energy for our activities. The rest energy is stored as glycogen.
What is metabolism?
Metabolism is the set of processes (which take place in our body) that turn the nutrients from the food we eat, into energy so that the components our body is consisted of are replaced

Fat and Cholesterol

Fat is the second source of energy. Fat acids are important for the development of the brain. Fat is a structural utility, providing thermal and mechanical protection to the body. It also regulates the metabolism. There are types of fat (good fats) that are needed and should be taken with the nutrition and some types of fat (bad fats) which are very bad for our health because of the influence they have on cholesterol levels. Saturated fats-bad fats . They are found in animal sources of protein such as beef, pork, ham and dairy products like full cream milk, ice cream, cheese. Many saturated fats raise the chances of heart disease by increasing blood cholesterol levels. Monounsaturated fats-good fats. They are found in olive oil, olives, almonds, walnuts, pistachios. They lower the bad cholesterol (LDL) without affecting the good cholesterol (HDL). We should consume olive oil in moderation and replace butter in our diet. Polyunsaturated fats . They are found in vegetable oils like corn...

Aerobic, strength, flexibility. Train the whole body

The importance of exercising the whole body is really huge. We have to exercise the front and the back side of it proportionally. When we workout the front of the thigh we should workout the back side as well in order to balance the result. The schedule in the gym should include a variety of exercises to practice all the parts of the body.  Without muscle balance, problems such as humps (strong chest - weak back), spine problems (dorsal strong - weak abs) may appear. This can happen as a result of a bad workout but also because of the fact that we don't workout at all. Our modern sedentary lifestyle leads to such imbalances. If we finally decide to include some action in our lives we must do it right... The workout should be stable, progressive and specific (it should be continuous, change progressively and be in accordance with our needs). Frequency (how many times a week), intensity (how much burden on the body), duration (how long) are required if we want to see the results. T...

Why don't we exercise? Reasons and excuses

The most common excuse not to go to the gym is lack of time. Are you really so busy that you can not consider putting exercising in your schedule? Did you spend your time on things that are not priorities? If you often use lack of time as an excuse for your absence from the gym, here are some ways to see what really happens: 1. Complete a list of 10 things that are very important for you (things you love in order of importance) 2. Write down 10 things you spend your time on. 3. Look at the second list and note the activities (like waiting in line, talking on the phone, stuck in traffic, watching TV etc) from which you can steal 10 minutes during the day. 4. Next to each one, write how much time you spend on it and make a third list with the time you lose every day. 5. Sum the time and get your daily total average. 6. Compare the first with the second list. Do you dedicate most of your time on what is important for you? Do you catch yourself spending time on things that are not that imp...
