When we think of the holidays, we often picture family gatherings and festive meals—from Thanksgiving turkey to Christmas dinners, not to mention New Year’s Day brunches. While these occasions can bring joy and connections with friends and family, there is a greater likelihood that individuals will overeat. Thanks to science and the medical profession, we have found new ways to lose weight. Whether it be through surgery, medications, or diets; we have more knowledge and resources at our disposal to address weight gain. Although America’s obesity rates have been declining recently (click here), the health benefits of weight loss can sometimes overshadow a critical point: rapid weight loss often brings unforeseen emotional challenges. Ignoring these challenges can lead individuals to experience unstable emotions or engage in self-destructive behaviors. Recognizing the emotional impact of rapid weight loss is vital.

Let’s take a look at what happens to our bodies when we lose weight. Weight loss triggers neurobiological and hormonal changes. There will be an increase in cortisol release. Cortisol is distributed by the adrenal gland in response to stress. The hypothalamus and pituitary gland regulate it. These changes influence regions of the brain associated with appetite and reward. Increased cortisol release has been associated with depression and suicide (link). For individuals who have emotional and psychiatric challenges before weight loss, they can be particularly vulnerable.

Rapid weight loss also influences our decision-making. This is brought up indirectly. Reductions in leptin levels can increase activity in our mesolimbic pathway. Leptin is a hormone produced by fat cells that helps regulate appetite and energy balance in the body. Our mesolimbic pathway is a system in the brain often referred to as the reward pathway. Reduced leptin activity in these regions will affect our cognitive (thinking) control (link). That will impact our ability to think through decisions.  

Additionally, we must take into account social and emotional considerations. Rapid weight loss will draw attention to individuals. For those unaccustomed to this attention, the situation can be challenging. There is a term called skinny privilege. It refers to the advantages that individuals with thinner bodies experience. Even positive attention is an uncomfortable feeling that people will need to sort through. Even positive attention is difficult for some to manage.

Increased or problem drinking is a risk factor for those who are undergoing rapid weight loss. If someone is using food to cope, reducing their food intake and changing eating habits, they will need to find another way to manage these feelings. This will put someone at risk for replacing one compulsive behavior, such as eating, with another, drinking. Individuals will turn to alcohol or other substances to help manage their emotions, as they are no longer turning to food as a way to cope. Individuals have a relationship with food. Some look to food to sustain themselves. Those people may not think about it much beyond that point. Others may look to food for comfort. If we take away the comfort food, they can feel unequipped to manage or cope with life’s challenges.

Energy levels are also affected, especially if weight reduction does not include a planned-out diet. Low energy could contribute to or increase negative emotions. Hormonal balances that happen with weight loss can affect sleep. Poor sleep can lead to unstable moods and poor decision-making. Loss of sleep not only affects our ability to address day-to-day problems but also our mood.

Lastly, we need to look at support systems. Others will look at you differently. Peers may see your weight loss as a threat to them. This perceived threat can stem from their own insecurities.  They can see you as a threat to their relationship with their significant other. It could be based on their inability to lose weight. This could also be influenced by how your peers perceive your weight loss. The peer group will see you differently, and that could change how you are viewed or treated within the group. Significant others will need to adjust to your new look, which could bring their own self-doubts to the surface.

. Consider these suggestions if you decide on a rapid weight loss program:

• Include a diet plan with your weight loss. This ensures you are getting the proper nutrients and vitamins and not just eating less.
• Include exercise in your program. This helps with energy and overall mental health.
• Engage in conversations with peers and significant others. You need their positivity and support.
• Monitor your emotions. This activity includes journaling your moods and activities.
• Set a limit (maximum) for your drinking or substance use.
• Seek a mental health therapist if you are finding your moods difficult to manage.

The problems we described with rapid weight loss are not inevitable. If you are considering losing weight, whether through medication, surgery, or diet, it is essential to anticipate not only the physical changes but also the emotional and social adjustments. Keeping these possible impacts in mind will help you prepare for a successful and sustainable journey.
