Typically, weight gain and obesity are caused by consuming more calories than the body needs, having an inactive (sedentary) lifestyle, and having poor lifestyle and dietary habits. In addition, studies have linked obesity to genetics and certain medical conditions, such as hypothyroidism, Cushing’s syndrome and polycystic ovarian syndrome. Weight gain may also be caused by the use of certain medications (such as corticosteroids, antiseizure medications and antidepressants), hormonal issues, stress, smoking cessation and lack of sleep.
Not getting enough sleep as well as poor quality sleep can have an effect on your immune system. Cytokines are proteins that are released during sleep and play an important role in your body’s ability to fight infections. Sleep disorders are quite prevalent in Australia with over 8% of the population living with sleep apnoea1, which occurs when the walls of the throat come together during sleep and block the airwaves above the voice box.
Indeed, stress symptoms can affect your body, your thoughts and feelings, and your behavior. Being able to recognize common stress symptoms can help you manage them. Stress that's left unchecked can contribute to many health problems, such as high blood pressure, heart disease, obesity and diabetes.
A steroid hormone known as cortisol helps the body control and deal with stress. When a person is in a dangerous or high-pressure situation, their body releases cortisol, and this can impact their metabolism. People often reach for food for comfort when they feel stressed. Cortisol causes those excess calories to remain around the belly and other areas of the body for later use.
One of the main reasons people don’t lose weight on the ketogenic diet is that they’re consuming too many carbs. To reach the state of ketosis a metabolic state in which your body burns fat for energy instead of glucose carbohydrate intake must be drastically reduced. In fact, only around 5% of your total calories should come from carbs. This is in stark contrast to the standard dietary recommendation that 45–65% of calories come from carbs.
