Common ways that prescription medications cause weight gain

You watch what you eat and make it a point to exercise every week. Then why doesn't the scale reflect your hard work? Your prescription medications may cause the weight gain, working against your efforts and making it harder for you to lose weight. Check out these common culprits.

Impact on appetite

Medications such as steroids, certain antidepressants, some antihistamines, and even birth control pills can increase your appetite. If you tend to eat in response to hunger, you may notice the scale starting to rise as you eat more to satisfy this new appetite level.

Impact on where fat is stored

Corticosteroids–often referred to as steroids or medicines that reduce swelling and inflammation–have two impacts on weight. For many people, they can cause an increase in appetite. They may also cause the body to redistribute fat to the stomach area. Many people notice increased stomach size faster than weight gain in other body areas.

Fatigue

Some medications leave you feeling tired and unmotivated. It can be harder to get out and exercise when you feel run down with fatigue. However, if you continue to eat and drink the same way you always have and burn fewer calories from less activity, you will gain weight.

Metabolism

Sometimes, although not common, a medication will actually lower a person’s metabolic rate. In this case, total calories burned are lower due to depressed metabolism. Beware of the impact on your energy level. You may have little energy, resulting in less motivation to stay active. Besides, you may search for an energy boost by eating more, which can have an even greater effect on creating a calorie surplus.

So if certain medications cause weight gain, what can I do to take the weight off?

Track your food and exercise

You gain weight if you eat more calories than your body needs or burns. Tracking helps you keep calorie intake and calories burned on target. MyNetDiary makes it easy to figure out how many calories your body needs each day and how many calories you actually eat.

Food choices matter

Make sure to get enough protein and non-starchy vegetables at each meal. Both plant- and animal-sourced protein and fiber can help fill you up using fewer calories. Also, try to avoid liquid calories and refined carbs and sweets. These foods are high in calories and not very filling or nutritious.

Don’t forget to include your doctor

Be sure to talk with your doctor if you suspect your medication causes your weight gain. While it can be tempting to stop medication cold turkey because you see sudden weight gain, it is not recommended. Ending medications suddenly could be risky. Instead, talk to your doctor about other possible options. For example, you can maybe switch to a lower dose of the same medication or find a comparable drug that doesn’t have the same impact on your weight.

It can be challenging to distinguish between weight gain caused by medications from other causes like subtle diet and lifestyle shifts. MyNetDiary is here to help you figure out what is going on with your weight!
