Avoid These Ultra-Processed Foods for Weight Loss

Losing weight doesn’t have to mean giving up all processed foods. In fact, many healthy staples like plain yogurt, canned beans, and whole-grain bread go through some form of processing. But ultra-processed foods those made with additives, artificial flavors, emulsifiers, and preservatives can quietly sabotage your goals.

Not only are these foods typically higher in calories, unhealthy fats, and sugars, but they’re also designed to be overconsumed. Studies have shown that people tend to eat 500 more calories per day when their diets are rich in ultra-processed options. Here are six types of ultra-processed foods to minimize if you're trying to lose weight.

1. Sugar-Sweetened Beverages

Drinks like soda, sweetened coffee, and energy drinks are among the top contributors to excess sugar intake.

• A 12-ounce can of soda has around 150 calories and 40 grams of sugar almost 10 teaspoons.

• These calories offer little satiety, meaning they don't help you feel full, which can lead to more snacking later.

• Sweetened beverages may also spike blood sugar, triggering cravings and energy crashes.

Better alternatives:

• Flavored sparkling water

• Fruit-infused water

• Unsweetened iced tea

• Coffee with a splash of milk or non-sugar sweetener

2. Ultra-Processed Meats

Convenient but often calorie-dense, meats like sausage, bacon, hot dogs, and deli slices are preserved through smoking, curing, or with nitrates and additives.

• A single hot dog with a bun can pack 300+ calories and 19 grams of fat.

• These meats are also high in sodium and saturated fat, which can contribute to water retention and metabolic issues.

Smarter swaps include:

• Canned tuna or salmon (5 oz: ~120 calories, 5g fat)

• Leftover grilled chicken (4 oz: ~200 calories, 6g fat)

• Boiled eggs (2 eggs: ~143 calories, 10g fat)

3. Frozen Ready-Made Meals

Yes, frozen meals are convenient but many are loaded with preservatives, emulsifiers, and flavor enhancers.

• Calorie counts range widely, from 350 to 600+ per meal, often with high amounts of saturated fat and sodium.

• Many fall short on fiber and lean protein, making them less filling.

What to look for:

• Meals with lean proteins like chicken or fish

• Whole grains (quinoa, brown rice, barley)

• At least 3 grams of fiber and 15–20 grams of protein

• Fewer than 600 mg of sodium per serving

Or better yet, meal prep your own healthy frozen meals for complete control.

4. Chips and Crackers

These crispy snacks are engineered to be addictive, thanks to salt, emulsifiers, and artificial flavors.

• A standard serving of potato chips (11 chips) clocks in at 160 calories and 10 grams of fat and let’s be honest, most of us eat double.

• These snacks offer minimal nutritional value and can lead to overeating.

Crunchy alternatives:

• Seasoned roasted chickpeas (1/4 cup: ~130 calories, 3g fat)

• Air-popped popcorn (3 cups: ~100 calories, 1g fat)

• Nuts or seeds (1/4 cup: ~160 calories, 14g fat just watch portion sizes)

• Rice cakes (1 large: ~35 calories, 0g fat)

5. Packaged Cookies, Cakes, and Desserts

These sweets are ultra-processed with refined flour, added sugars, preservatives, and artificial ingredients.

• Just three Oreos contain 160 calories and 14 grams of sugar and it’s easy to eat double that.

• These foods can trigger blood sugar spikes, hunger swings, and cravings.

More balanced dessert ideas:

• 1 oz dark chocolate (160 calories, 8g fat)

• 1/2 cup chocolate-covered fruit (133 calories, 6g fat)

• 1/2 cup berries with 1 tbsp almond butter (150 calories, 8g fat)

6. Granola Bars

Often marketed as healthy, many granola bars are loaded with sugar, refined grains, and artificial additives.

• Some bars contain over 15 grams of sugar more than a small donut.

• They may lack fiber and protein, making them more of a candy bar than a smart snack.

What to choose instead

Look for granola bars with:

• Whole ingredients (nuts, seeds, oats)

• <10 grams of sugar

• At least 3 grams of fiber

• 5 grams or more of protein

Or make your own at home using oats, nut butter, seeds, and dried fruit.

Why Ultra-Processed Foods Sabotage Weight Loss

Ultra-processed foods are designed for palatability and shelf life, not nutrition. They’re typically:

• Calorie-dense but nutrient-poor, making it harder to feel full.

• High in refined carbs and unhealthy fats, which can promote fat storage.

• Engineered to override hunger cues, leading to overeating.

A 2019 study published in Cell Metabolism found that participants consuming ultra-processed foods ate over 500 more calories per day than those eating unprocessed meals despite being offered equal calories and nutrients.

Final Thoughts

You don’t have to eliminate processed foods entirely to lose weight. The key is minimizing ultra-processed foods that are high in added sugars, unhealthy fats, and artificial additives. Focus instead on whole, minimally processed foods that keep you full and fueled.
