Hormonal Imbalances
In women, accumulation of fat takes place mainly due to hormonal imbalances that occur after menopause. Due to this, metabolism gets weaker resulting in accumulation of fat in the belly.
Genes
Probably, Genes may be one of the reasons for belly fat. In most cases, there is no solution for this and it happens generally.
Intake of too many calories
If you intake more calories than the required proportion, then it might transform into fat. This can happen when you have excess junk food and making it difficult for your body to burn calories. These excess calories will result in accumulation of fat.
Inadequate sleep
If you are not having adequate hours of sleep, then you may notice indigestion problem that leads to gas formation. This may puff up your belly and can make it look too flabby.
The first cause of belly fat is the sedentary lifestyle, which is defined as a lifestyle in which a person fails to exercise regularly, or fails to get any exercise at all. The biggest problem with a sedentary lifestyle is that it can increase your chances of developing serious health conditions, which are all somewhat preventable. If you lead a sedentary lifestyle, you are raising your chances of dying younger, yet you can easily avoid this by simply moving more and exercising regularly. A sedentary lifestyle commonly consists of the practice of sitting on the couch and watching too much TV. Such a lifestyle is not limited just to TV watching; a sedentary lifestyle also involves reading too much or using the computer too much. Basically, if you are not moving enough, it is sedentary.
Overeating is another well-founded cause of developing belly fat. Eating too much can lead to a gain of weight that can further manifest itself in the expansion of your waist. This is especially true if you fail to get in enough exercise on any particular given day. Weight gain is based on the simple principle of calories, specifically taking in too many calories while failing to burn off enough to counteract it. So if you eat too much food, and then lead a sedentary lifestyle, you are sure to start developing belly fat.
This cause of belly fat may be the toughest one to hear, because it entails not really being able to do all that much to prevent it. Genetics play a role in deciding where the fat distribution goes in your body, and it practically relates to two different body types. Either you are apple-shaped or pear-shaped. If you are pear-shaped, then the fat generally accumulates in your lower areas like your fanny. If you are apple-shaped, then your body has the tendency of storing fat around your midsection, thus leading to belly fat.
