How Hormones Influence Fat Loss or Gain

“Learn More About Weight-Related Hormones at MRC Fort Wayne”

There are many factors that affect how a person’s body accumulates body fat (adipose tissue) as well as what that person needs to do to restore hormonal balance to shed weight. Generally speaking, most people can improve their body’s chemical signaling to support the metabolic processes needed to lose unwanted subcutaneous and visceral fat deposits. However, every “body” is different, so engaging one-on-one with a coach can reduce the challenge.

Lipids are the general name of fats; and fats are triglycerides that play an important role in energy supply and fat storage. For the most part, triglycerides are obtained from your daily intake of food and are mainly synthesized by your liver, adipose tissue and small intestines. Insulin hormone plays a key role in lipid metabolism by inhibiting energy release and promoting excess storage as subcutaneous (under the skin) and visceral (surrounding organs) fat deposits.

Produced in your fat cells, leptin hormone signals the brain to reduce appetite and boost metabolism. But, in obese men or women, their brain can stop responding due to leptin resistance despite high fat storage. Cortisol hormone, on the other hand, promotes storage specifically around the abdomen, which drives cravings for high-fat, sugary comfort foods in response to false but chronic stress signals. Hypothyroidism (too low thyroid hormone) can cause weight gain and makes it more difficult to lose weight effectively.

How hormone imbalances affect body composition...

Whenever you start a weight loss journey, there is always a chance that your body will have a starvation response. This is due to drops in leptin levels that signal the brain to increase hunger to restore food intake and slow metabolism to make it harder to continue losing weight. When leptin resistance occurs, or when stress increases hormone levels, hunger signals become constant to ensure you have the energy needed for a “fight” or “flight” response. In addition, hormonal shifts then start to dictate a preference for where fat is stored. Naturally, more harmful visceral fat is stored as abdominal fat due to increased levels of cortisol hormone or reduced levels of the sex hormone estrogen. Nonetheless, lowering cortisol levels can be achieved through relaxing more often and improving the quality of sleep at night to minimize accumulation of belly fat. Fact is, good sleep regulates hormonal balance of ghrelin and leptin.

FOODS TO PREVENT FAT GAIN AND BOOST LOSS

Since insulin plays a critical role in so many hormones regulating lipid metabolism, prioritizing high-quality intake of protein each day along with healthy fats and complex carbs can help stabilize blood sugar levels, improve insulin sensitivity, and promote fullness to prevent over-consumption. In fact, a protein-forward menu plan focuses on low-glycemic variability to slow digestion and prevent sharp glucose spikes that are commonly seen following high-carb intake, especially of refined carbohydrates, sugary drinks, or overly-processed foods.

A protein-forward menu plan personalized to your body’s specific needs should start with lean sources of meats (chicken, turkey), fish (salmon, tuna), eggs, dairy products (Greek yogurt, cottage cheese), and plant-based options (tofu, tempeh). In addition, health fats (olive oil, avocado) help to slow down glucose absorption and act as the raw building blocks for producing key steroid hormones, such as estrogen, progesterone, and testosterone. Plus, omega-3 fatty acids (mackerel, walnuts, flaxseeds) are powerful anti-inflammatories that support chemical signaling.

Non-starchy whole foods (broccoli, kale, Brussel sprouts, bok choy) balance hormones by aiding in estrogen detoxification, regulating blood sugar, and reducing inflammation, while providing essential micronutrients. Cruciferous vegetables are key, as they contain compounds like indole-3-carbinol, which helps the liver break down and remove excess "used" hormones. Low-glycemic vegetables (spinach, Swiss chard) are also rich in magnesium that supports good adrenal health and help to naturally reduces cortisol (stress hormone) levels.

Imbalance in weight-related hormones can impact energy use and increase fat storage that leads to unintended weight gain. Common culprits include low thyroid hormone (slows metabolism), elevated cortisol (increased abdominal fat), and insulin resistance (extra subcutaneous and visceral fat storage). Hormonal imbalances are often triggered by stress, poor sleep, or bad dietary factors. At Metabolic Research Center, we have over three decades of applying the latest science to help you reach your personal goals. If you’re trying to decide whether a prescription-based weight loss plan or a more holistic metabolic weight loss program is right for you, contact MRC Fort Wayne today. One of our weight loss coaches will be in touch to discuss how hormone imbalances, genetic factors and key lifestyle habits may have slowed your metabolism and led to unintended weight gain. After all, hormonal balance can be restored and disrupted metabolic rates can be reset with a personalized approach.
