Stress and Weight Gain: How Lifestyle Balance Supports Healthy Weight

Stress has become an inevitable aspect of our everyday lives. Too much stress can make you complete tasks promptly, reach your deadline on time, resolve issues with clients, or make up with your loved one. However, dealing with stress every day is not a good thing, as it will cause chronic stress[1]. This condition can lead to several issues, such as brain fog, digestive issues, and depression. It can also hurt overall health, leading to high blood sugar levels and weight gain. Chronic stress can also prevent your body from managing cravings, leading to excess body weight. Are you dealing with too much stress and noticing the numbers climbing on the weighing scale? Keep reading to understand how stress and weight gain are associated, the link between weight management and hormones, and ways to avoid it.

How Modern Lifestyle Stress Impacts Body Weight

The stress induced by modern lifestyle is a highly ignored factor that affects your body weight. Weight gain occurs as a response by your body to prolonged stress, causing mental and physical changes[2].

1. Elevated Cortisol Levels

When facing chronic stress, it is natural for your body to produce the cortisol hormone, which is referred to as the stress hormone[3]. High levels of cortisol will induce food cravings and increase appetite to binge on foods high in sugar, fat, and calories[4]. With time, such unhealthy eating habits caused by the modern lifestyle will lead to the accumulation of abdominal fat, leading to stress and weight gain.

2. Emotional Eating

A modern lifestyle and too much stress and weight gain will cause emotional eating that will later affect your body weight. You might switch to comfort foods as a mechanism to cope with extreme work pressure, personal life issues, and anxiety. It will also increase your calorie intake due to unhealthy eating habits, causing sudden weight gain[5].

3. Effect on Metabolism

Experiencing chronic stress induced by a modern lifestyle every day might make your metabolism sluggish. It will interact with your body’s functions like fat storage and insulin regulation, leading to type 2 diabetes[6]. Such an imbalance in your metabolism will make the calorie-burning process a challenging task for your body.

4. Disrupted Sleep

You might be suffering from a poor sleep pattern or insomnia due to frequent stress and weight gain. Lack of quality sleep will alter your hunger hormones, such as ghrelin and leptin. These hormones would lower the feeling of satiety and increase hunger, leading to overeating and increased body weight.

5. Reduced Physical Activity

A modern lifestyle, coupled with a high-stress work environment, will make you feel fatigued, leading to feeling unmotivated to perform workouts. Modern lifestyle is often associated with sedentary habits, high-calorie consumption, and weight gain.

6. Poor Gut Health

A highly stressful life will affect your digestive health by disrupting the balance of good bacteria in the gut and slowing down digestion. It will also cause poor nutrient absorption, discomfort, and bloating, which can cause fluctuations in body weight.

Relationship Between Hormones and Weight Regulation

Regulating body fat is a complicated process, which is why your body needs hormones. Several hormones team up together to ensure that your bodily functions are well-supported by nutrients. These hormones also ensure that there is enough fat storage as a reserve and prevent body weight from fluctuating to extremes. Here’s how each hormone plays a vital role in the regulation of stress and weight gain.

1. Ghrelin

This hormone is produced in the gut and is referred to as the hunger hormone. It is responsible for making you eat, and when you are skipping a meal, the level of the ghrelin hormone shoots up, causing you to overeat. The foods you eat also have an impact on ghrelin levels, stress and weight gain. Consumption of carbohydrates, an effective macronutrient, will help bring down ghrelin levels. Protein is not so effective, but it will help suppress hunger for a long time. A meal balanced with carbohydrates and protein will help in lowering ghrelin levels effectively and maintain them for a long time.

2. Amylin

Your pancreas produces this hormone that controls your food intake. Several experiments have revealed that the amylin hormone is responsible for lowering leptin resistance to lead to weight loss. It is useful for people with diabetes to cut down blood sugar levels and helps in managing weight loss.

3. GIP or Gastro Inhibitory Peptide

Gastroinhibitory peptide hormone helps your body to detect nutrient fullness and can be combined with Glucagon-Like Peptide 1 hormone to treat obesity.

4. GLP1 or Glucagon-Like Peptide 1

It is yet another hormone with nutrient-fullness-sensing prowess secreted by your intestine while you eat. It creates a feeling of fullness and makes you stop eating immediately. It also helps in blood sugar level management by bringing it down after eating. As GLP1 levels tend to vary from one individual to another, the feeling of satiety is also different. When ghrelin levels are higher, the GLP1 level would be lower, causing you to eat more causing stress and weight gain. This is why doctors prescribe GLP1 hormone for treating obesity to create satiety and fullness quickly to prevent overeating.

5. Thyroid Hormones

Your thyroid secretes hormones that perform the function of metabolism. Specific thyroid conditions like hypothyroidism or hyperthyroidism will affect the hormone production, leading to weight loss or weight gain. Having an overactive thyroid gland might also lead to weight gain.

6. Insulin

It is a primary hormone responsible for blood sugar regulation and is secreted by the pancreas. The insulin hormone transports sugar to major organs in your body and can influence your satiety and hunger levels. High levels of insulin will cause an accumulation of body weight, resulting in obesity. It will also interact with other hormones in your body to cause loss of appetite and more.

7. Cortisol

Your adrenal glands secrete the cortisol hormone as a response mechanism[7] to cope with stress[8]. When facing chronic stress, your body will produce high cortisol levels, which will lead to an increased appetite, stress and weight gain, along with belly fat accumulation[9].

8. Glucagon

Your pancreas is responsible for the production of the glucagon hormone when there is a decline in sugar level, even after a meal. It helps by restoring the sugar level by signalling the liver to release the reserve sugar. This hormone activity will prevent you from gorging on snacks between meals by controlling cravings, stress and weight gain. It also acts as an appetite suppressor, metabolism booster, and induces weight loss.

9. Leptin

This hormone is associated with your body fat and informs your brain regarding its storage to maintain ideal body weight. When you put on excess weight, there will be a spike in leptin levels leading to stress and weight gain. So, there will be a loss of appetite, and energy expenditure will increase to bring down your body weight. Similarly, when you lose weight, the leptin levels decline, causing you to overeat and slow down metabolism. Obese people often face ‘leptin resistance’ where the level of this hormone will be higher, but weight loss will never happen.

Role Of Sleep and Recovery in Weight Management

1. Sleep and Its Impact on Hunger Hormones

Sleep directly impacts your hunger hormones – leptin and ghrelin. Inadequate sleep will make you crave foods with high caloric value. The leptin hormone makes you feel fuller and prevents overeating, contributing to weight management.

2. Sleep and Metabolism

When your body is deprived of sleep, it causes your metabolism to slow down and prevents it from burning calories effectively. Studies show that inadequate sleep can lead to insulin resistance, contributing to fat storage and weight gain[10].

3. Triggers Cravings

Have you felt the urge to relish sugary and fried foods after not sleeping well? It is because lack of sleep hinders the reward circuit centre of your brain, making you crave junk food[11]s. It leads to late-night snacking and binge eating, which will increase your body weight.

4. Raises Cortisol Levels

Inadequate sleep can increase your stress hormone, cortisol, which stores fat in your abdomen. It also makes you eat more snacks, junk foods, and sugary drinks, causing weight gain. It will also cause muscle loss and prevent the body from burning calories quickly.

5. Decreased Muscle Recovery

When you are into strength training, your muscle fibres will develop microtears, which have to heal quickly to support muscle growth. You need to get a good night’s sleep to facilitate muscle recovery and prevent soreness and sluggish progress.

6. Lower Endurance and Energy Levels

Not getting enough sleep will decrease your energy levels, making you struggle during workouts. Inadequate sleeping hours will lower endurance, causing fatigue to set in, and workout sessions will become tougher.

7. High Chances of Injury

Your sleeping hours determine your body balance, reaction time, and coordination. When you don’t sleep well, there are high chances of tripping during workouts and getting injured.
