Why we gain weight
Wikipedia defines the causes of weight gain to be a caloric imbalance. This is a rather simplistic view. According to this theory, you gain weight when you consume more calories than you expand. This theory is coming under increasing attack in recent times. Most people gain weight because of the way their bodies partition calories. When you eat something, your body decides how to use those calories. Some portion may be used by the body for energy while the rest may be stored as fat for use at a later stage. Your hormonal system is the single biggest influence on how your body partitions the calories that you consume.
Gary Taubes goes to great length to explain the effect of calorie partitioning in his book entitled “Why We Get Fat“. This book is worth reading as Gary has backed his writing with extensive scientific research.
Lifestyle and your genetics
Most people blame their genes as one of the main causes of weight gain. Genes do have a role to play but genes cannot act alone. Genes react to your lifestyle. If you have genes that will increase your propensity to gain weight, your lifestyle will ultimately affect how bad the effect will be. Genes are like a loaded gun. Lifestyle can either help pull the trigger or keep the loaded gun in the holster.
Hormones and weight gain
Your lifestyle affects key hormones that ultimately decide how your body partitions calories. One of the main hormones that comes into play is insulin and it is one of the main causes of weight gain. Insulin is a very potent fat storage hormone. You will find it extremely difficult to lose weight when your insulin levels are elevated. When insulin is elevated, the body is inclined to store calories as fat rather than burning it. This is a condition known as insulin resistance. Learn more about the role of insulin as one of the main causes of weight gain from the following resources ;
Your food and exercise choices will affect if your insulin levels remain elevated. It will also affect the release of fat burning hormones such as testosterone or human growth hormone.
Hormonal balance is also affected by aging. When you age, your hormonal balance is compromised and there is a tendency to gain weight. Aging affects the production of testosterone, growth hormones and other fat burning hormones.
Your lifestyle directly affects your hormonal balance. Your hormonal balance influences your cravings and energy levels. This gravitates you more towards a unhealthy lifestyle. An imbalance in your hormonal system could cause you to become sluggish. An unhealthy lifestyle could accelerate aging which increases the rate of weight gain. Accelerated aging disrupts your hormonal system even further. As you can see, these factors are inter-related.
22 causes of weight gain
As mentioned earlier, causes of weight gain are largely influenced by lifestyle, hormonal balance, aging or a combination of the three. You will find below the 22 most common causes of weight gain.
1. Calorie dense food – This is the amount of calories contained, in say a pound of food. This is one of the major causes of weight gain. A study published in the American Journal of Clinical Nutrition in 2004 identified calorie density as one of the obvious causes of weight gain.
One such culprit is fast food. Most fast food also contains lots of trans-fatty acids which cause severe havoc in your body’s metabolism. Most calorie dense food are filled with sugar, fat or a combination of the two. The body has its inbuilt mechanism to assess satiety levels. Calorie dense food such as a large bugger does not give your body’s satiety system enough time to react. By the time your body realizes that you have overeaten, it is usually too late.This was also evident in the 2004 study published in the American Journal of Clinical Nutrition.
Calorie dense food also have the lowest nutrient density.

2. Simple carbohydrates – Simple carbohydrates cause insulin spikes. Repeated insulin spikes bring about a condition known as insulin resistance. This is a condition where the body becomes resistant to the effects of insulin. Insulin is required to allow cells to absorb glucose molecules. With insulin resistance, the cells become desensitized to insulin. More insulin is required to accomplish the same task. The high levels of insulin linger around thus making it extremely difficult to lose weight. It makes it very easy to gain weight. You should completely remove refined carbohydrates from your diet.

4. Alcohol consumption – Alcohol consumption is another one of the insidious causes of weight gain. Even a single drink of alcohol can halt fat burning for up to 24 hours.

5. Skipping breakfast – Studies have shown that people who skip breakfast have a tendency to accumulate abdominal fat. Most people do not realize this as being one of the causes of weight gain. People who skip breakfast put the body into a prolonged state of starvation. When they finally eat during lunch, the body greedily stores calories as fat. The body thinks that there is a shortage of food and thus becomes paranoid of wanting to store calories as fat.

6. Skipping meals – The body needs to know that it can get its meals at a predefined time. When you skip a meal or eat it at an irregular time, the body becomes paranoid.

Eating 5 to 6 small meals can help your weight loss efforts tremendously by assuring your body that there is a constant supply of food. This avoids your body from moving into starvation mode.
