Ultra-processed foods are a major part of modern eating. They are convenient, inexpensive, and engineered to taste good. In the United States, they now make up almost 60 percent of the average person’s daily calories. Most people eat them without even realizing it because these foods have become the norm rather than the exception.
For individuals using GLP-1 medications such as Ozempic, Wegovy, Mounjaro, or Zepbound, understanding ultra-processed foods matters more than ever. These medications help regulate appetite, improve blood sugar control, and support weight loss. But the foods you choose can either work with the medication or make your results harder to achieve.
What Exactly Are Ultra-Processed Foods?
All foods fall somewhere on a processing spectrum. Washing, chopping, milling, freezing, canning, and fermenting are all forms of processing. These steps make foods safe, affordable, and easier to store.
Ultra-processed foods are different. They are created using industrial food techniques that transform raw ingredients into highly refined products. They often contain few or no whole foods and rely on added sugars, additives, colorings, thickeners, and artificial flavors.
Ultra-processed foods usually include:
• Ingredients not found in home kitchens
• Multiple steps of industrial processing
• Additives that enhance taste, shelf life, or texture
Examples of processes used to make UPFs include:
• Hydrogenation of oils
• Extrusion to shape cereals and snacks
• Isolating starches, sugars, and proteins from whole foods
• Adding emulsifiers, stabilizers, and flavor enhancers
The result is food that tastes good, lasts long, and is inexpensive to make, but is highly altered from its natural state.
Common Examples of Ultra-Processed Foods
UPFs are part of daily life for most people. Here are common examples:
• Sugary drinks such as soda and flavored coffees
• Packaged snacks such as chips, crackers, and cookies
• Frozen meals, including pizzas and microwaveable entrees
• Processed meats like sausages, hot dogs, and nuggets
• Sweets and treats such as candy and ice cream
• Flavored yogurts and sugary breakfast cereals
• Protein bars and some bottled protein shakes
• Shelf-stable cheese spreads and processed cheese slices
Many foods marketed as healthy or “natural” are still ultra-processed. Labels can be misleading, so ingredients matter more than marketing terms.
Minimally Processed Foods vs Ultra-Processed Foods
Minimally processed foods undergo simple preparation steps but retain their natural structure and nutrients.
Examples include:
• Fresh or frozen fruits and vegetables
• Whole grains such as rice or oats
• Beans and lentils
• Plain nuts and seeds
• Fresh meat, seafood, and poultry
• Simple breads made with flour, yeast, water, and salt
Ultra-processed foods, by comparison, often include:
• Refined flours
• High-fructose corn syrup
• Artificial colors
• Preservatives such as sodium benzoate
• Emulsifiers like soy lecithin
• Additives created in labs rather than kitchens
The degree of processing drives the difference in health impact.
How to Identify Ultra-Processed Foods
If you're unsure, check the ingredient list. UPFs often include:
• Ten or more ingredients
• Names you do not recognize
• Additives to change color, texture, or shelf life
Common UPF indicators include:
• Hydrogenated oils
• Maltodextrin
• Artificial sweeteners such as sucralose
• Whey protein isolate
• Color additives
• Flavor enhancers such as MSG
These ingredients are not harmful individually, but together in large amounts they create food that affects metabolism differently from whole foods.
5 Reasons Ultra-Processed Foods May Be Harmful
Research shows that diets high in UPFs are linked to chronic health problems. Here is what studies reveal.
1. Effects on Physical Health
Eating large amounts of ultra-processed foods is associated with increased risk of:
• Obesity
• Heart disease
• High blood pressure
• Type 2 diabetes
• Certain cancers
• Inflammatory bowel disease
These effects often stem from high levels of added sugar, unhealthy fats, and low fiber content.
2. Impact on Gut Health
UPFs may alter the gut microbiome. Some emulsifiers and additives can disrupt the gut lining, increase inflammation, and possibly contribute to digestive disorders.
3. Influence on Eating Behavior
Ultra-processed foods are designed to encourage overeating.
Reasons include:
• Combination of sugar, fat, and salt that triggers reward pathways
• Soft textures that are easy to eat quickly
• Higher calorie density
People often eat more than intended, even when they are not hungry.
4. Mental Health Effects
Growing research links UPFs to increased symptoms of:
• Anxiety
• Depression
• Stress
The connection may involve inflammation, gut changes, or blood sugar fluctuations.
5. Reduced Longevity
Large studies show that people who consume the highest amount of UPFs have a higher risk of early death, especially from cardiovascular disease and metabolic disorders.
How Ultra-Processed Foods Affect GLP-1 Medication Results
If you take medications such as Ozempic, Wegovy, or Mounjaro, reducing UPFs can significantly improve your experience.
Better Blood Sugar Stability
GLP-1 drugs help reduce glucose swings. UPFs cause rapid blood sugar spikes and crashes that work against the medication.
Stronger Appetite Control
GLP-1 medications lower appetite by affecting hunger hormones. UPFs bypass these signals, making overeating more likely.
Fewer Side Effects
People often report less nausea, bloating, and reflux when eating minimally processed foods while on GLP-1 drugs.
Improved Weight Loss Results
Whole foods are more filling, higher in nutrients, and naturally support fat loss.
How to Reduce Ultra-Processed Foods Without Stress
You do not need to eliminate UPFs entirely. Small, realistic changes make a big difference.
Try these strategies:
• Plan simple meals ahead of time
• Use leftovers as next-day meals
• Swap deli meats for cooked chicken or beans
• Flavor water with fruit instead of drinking soda
• Keep whole-food snacks on hand such as nuts or fruit
Frozen fruits and vegetables are excellent minimally processed options.
Focus on What You Can Add
Instead of focusing only on removal, aim to add:
• More whole foods
• More fiber
• More protein
• More hydration
Balance matters more than perfection. UPFs can still fit into your diet intentionally and without guilt.
The Bottom Line
Ultra-processed foods are convenient and common, but high intake is linked to chronic health conditions and poorer metabolic health. For people using GLP-1 medications, reducing UPFs can enhance appetite control, lower blood sugar swings, and improve weight loss outcomes.
You do not need to completely eliminate these foods. Small changes and mindful swaps can support better health and align with your medication goals. Aim for balance, flexibility, and sustainable eating habits that match your lifestyle.
