Why Am I Gaining Weight? Maybe It’s The Weather

Posted on:

In many parts of the country, hibernating animals are busily preparing for the winter, eating and eating and eating as they build up the energy stores that will sustain them until spring. And many humans are doing something similar!

What happens during hibernation?

During hibernation, animals’ metabolism, oxygen consumption, heart rate, blood pressure, and body temperature all decrease to ensure that the animal burns as few calories as possible thus extending their energy stores. In this state of decreased metabolism, the animal’s body uses lipids (fatty acids) rather than carbohydrates to produce energy. During the hibernation period, an organism will lose about 40% of its body weight.

Can humans hibernate in winter?

As much as some humans might want to curl up in a ball and hibernate during the cold months of the winter, our bodies are not made to undergo the drastic metabolic changes necessary to enter a true hibernation. Many humans, however, do notice bodily changes associated with the drop in temperatures.
People who suffer from a specific kind of depression called seasonal affective disorder, or SAD, often liken their condition to hibernation, and researchers have suggested that SAD is in fact a bodily reaction to the shorter daylight hours in winter. But unlike major clinical depression, where people typically lose their desire to eat and have trouble sleeping, people with SAD frequently sleep more than average and note an increase in their appetite and food consumption, often leading to weight gain.

Have you put on some extra “insulation” for winter?

As winter approaches, if you find you are putting on pounds, be sure to consult with your doctor. In addition to talking with you about a healthy diet and exercise, your doctor may want to run some blood tests to see if there is any cause for concern related to your weight change. Some of the tests your healthcare provider may recommend include:

  • Cortisol: Also called the “stress hormone” or the “fight or flight hormone,” cortisol increases adrenaline production in stressful situations. While it can benefit the body, increasing awareness and immunity as well as reducing pain in the short-term, too much cortisol on an ongoing basis can damage the thyroid, bone, and muscle. It can also decrease long-term immunity and contribute to the production of belly fat.
  • Homocysteine: A risk factor for heart disease, this protein is typically elevated in people with insulin resistance.
  • Insulin and Glucose: Those with diabetes do not produce sufficient insulin to process the body’s glucose. But high insulin is also problematic, causing the body to accumulate glucose as stored fat but not allowing the body to metabolize that stored fat for energy.
  • Liver Function:  If liver function is compromised, the body can struggle to remove hormonal waste and burn fat.
  • Testosterone: This hormone (found in both males and females) is responsible for sexual function and development, but it is also crucial for brain, bone, muscle, and vascular health, as well as fat dispersal.
  • Thyroid Tests: The “master gland,” the thyroid produces hormones that are crucial for healthy metabolism. If it is not functioning properly, the body will not be able to properly process food’s energy.
  • Vitamin B-12 and Folate (also known as Folic Acid): In order for the body to work effectively as a fat burner, insulin levels must be steady, and these are key ingredients for creating that stability.
  • Vitamin D: Vitamin D deficiency can cause the body to accumulate belly fat, as well as improperly process food. It is also a crucial element for bone health.

While there are many potential causes of weight gain, the results of these lab tests can help your healthcare provider assess the condition of your body and offer suggestions on the best approach to weight loss.
