Aside from strengthening muscles and bones, they protect the heart from the so-called myocardial infarction (heart attack) because through physical exercises, the small blood vessels supplying the heart with blood are assured of being open most of the time, in addition to the development and opening of others, medically known as the collateral coronary arteries.

If your weight is more than your so-called ideal body weight, you will soon develop hypertension; and since hypertension has a lot of complications, you will soon have more medical problems than you have thought and imagined. Aside from diseases in the heart and blood vessels, if you are overweight, you will also have problems pertaining to your knees and other joints, aside from the fact that you will be prone to having bone fractures.
Eating between meals
If you take light snacks in between meals, then that is okay and tolerable. However, if you take a lot of foods prior to, and after, your regular meals, then that spells a lot of difference because intake of large amount of foods could cause sudden rise of your sugar, cholesterol, or triglycerides in your blood depending on what type of foods you took in.

When you take your dinner at 7:00 o’clock in the evening and take your breakfast the following day at 7:00 o’clock in the morning, the time difference in between the two meals is 12 hours. If you take your lunch at 12:00 noon, the time difference is only 5 hours. And if you take your dinner again at 7:00 o’clock in the evening, the time difference is only 7 hours.Among your regular meals, breakfast has the longest time difference from the previous meal. Thus, it is called breakfast because when you take it, you are actually breaking your fasting! This is the reason why breakfast is so important because you need to replenish a lot of substances consumed by your body in the last 12 hours.
Sleeping too little or too much
