After years of substance use, Shelly finally found herself on the other side. Six months sober, she’s living a life that she once thought impossible. That’s the good news.

Now for the bad news: Shelly’s gained 30 pounds.

She thought she’d made a healthy decision to get sober. So why is she putting on this much weight...something that’s clearly not healthy?

Weight Gain and Recovery

Shelly’s just one of the 65 percent of people who gain weight in recovery. Since it’s such a common occurrence, there must be common causes, right? Yes, there are.

If you’ve noticed the scale starting to tip in your newfound sobriety, it’s most likely due to one or more of the following factors.

You’re Out of Practice

Before you got sober, how much time and energy did you spend planning healthy meals, exercising, and ensuring your body’s proper nutrition? If your answer’s anything but zilch, you’re a rare find.

While all of your energy was focused on your recovery, you weren’t concerned about these things. Once sober, maybe you developed the habit of getting a “quick fix” via food.

Maybe you consume a lot of fast food or processed junk instead of nutritious meals. Or maybe you don’t make time for exercise.

No matter the details, you need to change these old habits and start taking better care of yourself physically.

Your Body’s Repairing Itself

How long was your body deprived of proper nutrition? Months? Years? Decades?

Substance abuse damages organs, disrupts normal body functions, and creates nutrient deficiencies.

In early sobriety, your body is healing. These repairs require large amounts of nutrients, such as healthy fats, proteins, and vitamins.

You’re Self-Medicating With Food

Did you know food can stimulate your brain in ways similar to drugs? Sugary, fatty, and salty foods light up our brain’s reward center and cause the release of “happy chemicals.”

When you’re no longer using substances to achieve this high, you might turn to food as a substitute. It’s also a common coping mechanism to use food to deal with withdrawal and cravings.

The important thing is not to give in to these urges. If you do, you can develop a tolerance just like you did with drugs.

You require more and more food to achieve this “high” and continue in this cycle until you’ve substituted drug addiction with food addiction.

You’re Not Doomed to Obesity

Weight gain can be a common struggle in recovery, but it doesn’t mean you’re failing. With the right support, you can heal both physically and mentally. Use Recovery.com to find and compare treatment programs, including options that offer nutrition counseling, meal planning support, and whole-person care, so you can build healthier habits and a balanced life in recovery.

FAQs

Yes. Weight changes are common in early recovery, and many people gain weight after quitting substances. For some, this is partly because appetite and daily routines shift as your body stabilizes and you build new coping skills.

Highly palatable foods like fatty and sugary snacks can activate the brain’s reward system, which is also involved in addiction and cravings, according to the National Institute on Drug Abuse (NIDA). When you stop using substances, it's common to reach for food that gives quick comfort or a dopamine boost, especially during stress or withdrawal.

Not at all. Weight gain can happen while your body and brain heal, and it does not mean you are failing. If weight changes feel distressing or unmanageable, it can help to talk with a clinician or dietitian so you can support recovery without swapping one coping strategy for another.

Substance use can disrupt appetite, digestion, and nutrient absorption, contributing to malnutrition and deficiencies. In recovery, rebuilding nutrition and regular eating patterns can change hunger cues and energy needs, which may affect weight as your body repairs.
