“Why can’t I lose weight with diet and exercise? I have changed my diet, I exercise on a regular basis but still I can not reach the desired weight.”
That’s a big problem for many people who are trying to get rid of excess body fat. Here we reveal the true causes that prevent you from getting slimmer.
Dr. Libby Weaver, a nutrition and biochemistry specialist in Australia, points out that there are mainly 5 factors responsible for difficulties in a slimming process.
On one hand, we have psychic factors like – stress, emotions and nervous system, and physical factors like – insulin resistance and hormonal changes.
The relationship between psychic and food
Stress is guilty of numerous dysfunctions of your body. We all know that everyday worries, pressure at work, tense family relationships or in your circle of friends are situations with negative consequences.
When subjected to such stressors, the body is alerted and increases the secretion of cortisol and adrenaline. These “stress hormones” cause metabolic changes that lead to weight gain.
In addition, stress is closely related to negative emotions (sadness, anxiety, irritability, insecurity) that are the cause of the phenomenon called “compulsive eating“.
Often, people in this situation are looking for refuge and comfort in food. Food becomes a source of compensating the feelings of dissatisfaction, frustration, restlessness.
In this context, the essential question is not “what do we eat?” but “why do we eat?”.
The nervous system plays an active role in maintaining the metabolic balance of the body. Unbalanced eating, chronic fatigue, disorganized lifestyle, and other factors that affect the nervous system’s health contribute to the development and maintenance of obesity.
For example, it has been shown that people who don’t sleep enough have a much slower metabolism and burn fewer calories than those who fulfill their sleeping needs.
Resistance to insulin, the hidden cause of obesity
Most overweight people have insulin resistance, meaning that their body does not use this hormone which is produced by the pancreas, for digestion.
When we eat, much of the food is turned into glucose (the blood sugar), the main energy source of the body. Once the blood reaches the pancreas, this organ detects a high level of glucose in the blood and knows how to release insulin to allow cells throughout the body to use glucose.
Cells have insulin receptors that allow glucose to penetrate to their level. The cells either uses glucose as an immediate source of energy, or stores it as a future source of energy.
For people who have developed insulin resistance, this system is completely unregulated. The pancreas receives signals that it has to release insulin, but it does not reach the cell level due to the phenomenon of resistance.
Glucose accumulates in the blood and does not reach the cells in the body. Then, what does the body do in response?
Enter into the survival mode and store any energy source as fat deposits. All of the glucose that cells are getting is absorbed directly into the fatty tissue, with more and more fat being stored on your entire body.
Thyroid and body weight
The thyroid gland is also very important in controlling body weight. It dictates the rate of metabolism, that is, how cells burn energy. Each cell in the body has receptors for thyroid hormones.
Therefore, when thyroid hormones are in excess, metabolism will be accelerated (hyperthyroidism), and when the thyroid does not secrete enough hormones, metabolism will be slow (hypothyroidism).
Hypothyroidism is characterized by weight gain and inability to lose weight, menstrual disorders, fatigue, constipation, cold hands and feet, depression, dry skin, brittle hair and nails.
A typical form of hypothyroidism in women is in the case of conditions such as polycystic ovary syndrome, endometriosis, infertility.
On the other side is hyperthyroidism which is characterized by excessive weight loss despite an increased appetite.
Both conditions are preventing you to obtain your desired body weight and any attempts to lose or gain weight are ineffective and will make you more frustrated.
So, before deciding to start any diet or training program to lose weight, it is recommended that you take a rigorous medical exam and make sure that you don’t suffer of any condition that will prevent you get any real results.
