- fish
- Tofu
- egg
- Low-fat dairy products

Healthy fats are those found in foods including:

Foods to limit: Processed foods, sugary snacks, and fried foods
While some foods can help you during intermittent fasting, others should be limited to avoid negative effects on energy levels and satiety signals.
Ultra-processed snacks, sugary desserts, and fried foods are often high in unhealthy fats, refined sugars, and empty calories, which can lead to a rapid energy crash and increased hunger. (15)
Some examples of foods to avoid:
- Sugary snacks: candy, pastries, donuts, and sugary cereals
- Ultra-processed snacks: potato chips, packaged cookies, and crackers
- Sugary drinks: soft drinks, sweetened coffee drinks, and fruit juices with added sugar
- Fried items: French fries, fried chicken, onion rings, fried fish
- Pre-packaged frozen meals: frozen pizza, microwave dinners, and processed prepared foods
