Obesity and its Causes
The amount of calories consumed and the amount of calories which are burnt during daily activities determines our body weight. However, there are several other factors which cause obesity. These are:
- Physical inactivity
- Emotional or psychological issues
- Diet rich in calories and fat
- Some medical problems/medications
BMI or body mass index is a number which takes height and weight of an individual into consideration and is calculated accordingly. An ideal BMI ranges from 18.5 – 25. If it is less than 18.5, then it is considered underweight. If it is in the range 25-30, then it is considered overweight. BMI crossing 30 is considered obese.
Required Calories To Maintain Ideal Weight
There is a formula known as the Harris-Benedict equation which is used by physicians to determine the caloric needs. This equation gives a basal metabolic rate, the amount of calories required to preserve body functions such as respiration, heart rate, brain function and body temperature. The figures given by the equation are based on averages of the population. Individuals with muscles may need more calories than what is given by this equation. Individuals who are overweight or obese may need lesser calories. On an average, women need approximately 2000 calories per day, and men need 2500 calories per day for maintaining weight. For weight loss, 500 calories per day needs to be subtracted along with increasing physical activities in order to lose weight.
Ideal Nutrition and Diet for Maintaining Ideal Weight
A healthy and balanced nutritious diet consisting of 3 meals per day including all types of food, i.e. proteins, carbohydrates, vegetables, fruits and less fat, oil and sugar etc. is needed for losing weight or maintaining health weight. Foods such as fried foods, high in fat and sugar, snacking in between meals, sugared drinks and sodas, etc. should be eliminated from your diet if you intend to lose weight or maintain an ideal weight. Appropriate portion sizes should be taken, second helpings should be avoided and as well as eating between meals should be avoided if one wants to maintain ideal weight.
Impact of Drinking Alcohol or Wine or Beer on Weight
The body absorbs alcohol very rapidly after its intake. As it is a toxin and there is no place to store it in the body, it is used as an energy source instead of carbohydrates and fats resulting in accumulation of the excess carbohydrates and fats which is not used as energy and is stored as fat. This causes slower weight loss. So, it is advised to avoid alcohol for weight loss; however, it can be taken on a rare occasion.
