A Dietitian’s Take on GLP-1s: What You Should Actually Know
GLP-1 medications are everywhere right now, and with that visibility has come a lot of confusion and misinformation.
We spoke with Kristian Johansen, Registered Dietitian Nutritionist and Personal Trainer at FFC Oak Park. His perspective is clear: GLP-1s can be powerful tools, but only when used appropriately and with the right support.
What GLP-1s Were Designed For
GLP-1 medications were originally created to help manage blood sugar, particularly for individuals with diabetes.
Today, they are also prescribed for:
- Weight management tied to chronic conditions
- Cholesterol or cardiovascular risk factors
- Obesity-related health concerns
In these cases, they have been highly effective in improving both weight and overall health.
How GLP-1 Weight Loss Works
GLP-1s change how your body responds to food by:
- Slowing digestion
- Increasing feelings of fullness
- Reducing food cravings
Most people see around 10 to 15 percent weight loss along with improved blood sugar control. These results are tied to continued use, which is why having the right plan in place matters.
The Reality: This Is Not Short-Term
GLP-1s are not a quick fix.
“They are more of a long-term tool,” Kristian says. “Once you stop, appetite typically returns.”
That is why results depend on what you build alongside the medication:
- Strong nutrition habits
- Maintained muscle mass
- Consistent routines
What Most People Overlook
GLP-1s are generally safe long term, but there are important considerations. These include:
- Digestive side effects early on
- Risk of nutrient deficiencies due to lower intake
- Potential muscle loss with rapid weight loss
Muscle loss can impact metabolism, strength, and long-term results.
Why Dietitian Guidance Matters with GLP-1 Weight Loss
This is where most people get it wrong: GLP-1s should not be used on their own.
“When you are on a GLP-1, it is critical to work with a dietitian and a personal trainer,” Kristian says.
That support helps you:
- Maintain muscle through strength training
- Eat enough protein and nutrients
- Lose weight at a sustainable pace
- Build habits that last beyond the medication
With the right support, the focus shifts from just losing weight to actually improving long-term health.
So, Should You Go on a GLP-1?
For individuals with chronic conditions, GLP-1s can be an effective tool. For simple weight loss, they are not typically recommended without medical need.
This decision should always be made with a provider and supported by a clear plan for nutrition and training.
The Bottom Line
GLP-1s are not a shortcut; they are a tool. At FFC, we focus on helping you use that tool the right way, with expert guidance and a plan built for long-term results.
Because the goal is not just weight loss. It is feeling strong, capable, and healthy long term.
