Weight gain is primarily caused by eating more than we lose. If you consume a high amount of energy, particularly fat and sugar, and you don’t burn it away, there will be an excess of energy in your body. It’s this excess of energy in the body that leads to weight gain. If not checked, accumulation of weight gain can lead to obesity and obesity can be life threatening.
The amount of energy in food and drink is measured in what is called calories. If we consume foods that are high in calories without burning the same, we are going to gain weight overtime.
For someone that is health-conscious or trying to lose weight, it’s a must for you to understand how many calories you consume and how many of it you should burn. If you are trying to lose weight for instance, you must burn more calories than you consume or burn the exact amount you consume if you are trying to keep your weight.
As a guide, a man needs an average of 2,500 kcal (calories) a day to maintain a healthy body weight. For a woman, it’s around 2,000 kcal. What this means is, as a woman, if you consume more than 2,000 kcal, you need to take some supplements and/or exercise to burn the excess calories, and if you fail to do this, you will add weight.
