What Makes a Good Keto Lunch?
A good keto lunch keeps net carbs (total carbs minus fiber) low while delivering filling fat and protein. To stay in ketosis, your lunch should:
- Be low in net carbs, usually about 10-15g, since keto limits total carbs to roughly 20-50g per day (Harvard T.H. Chan School of Public Health)
- Include moderate protein (like chicken, beef, tuna, or eggs)
- Include healthy fats (like olive oil, avocado, cheese, or butter)
What to avoid: Bread, rice, pasta, tortillas, sweetened dressings or sauces, and most takeout unless you customize it.
According to Cleveland Clinic, it's important to eat real, whole, fresh foods on keto, like meat, eggs, low-carb veggies, and healthy fats, rather than processed foods.

Office and On-the-Go Tips

Batch and freeze: Freeze leftovers in single portions for grab-and-go convenience
Leftover Lunch Wins
One of the easiest keto lunches is dinner from last night.
Reheat, repurpose, or eat cold: leftover chicken, beef, or roasted veggies all work. I do this at least three times a week, and it saves both time and money. Cook a little extra at dinner and tomorrow's lunch is done. Browse our keto dinner ideas for batch-friendly mains.
Some of our meal plans include dinner-to-lunch transitions. Try our Beginner Keto Meal Plan if you're just getting started.
Should You Skip Lunch?
If you're doing intermittent fasting (IF), you might skip lunch and eat two meals a day. That's okay, but not required.
If you're hungry at lunch, eat. Skipping meals when you're new to keto can backfire and lead to overeating later.
Mayo Clinic notes that intermittent fasting isn't for everyone. It's not recommended for people who are pregnant or breastfeeding, under 18, have a history of disordered eating, or have certain conditions like diabetes, so check with your doctor first.
Frequently Asked Questions
How many carbs should a keto lunch have?
Aim for roughly 10-15g net carbs. This gives you room for carbs at breakfast and dinner while staying within your daily 20-50g total.
Can I eat the same lunch every day?
Absolutely. Many successful keto eaters repeat their favorites. It simplifies meal prep and shopping. If you enjoy variety, batch prep two or three options each week.
What about eating out for lunch?
Look for grilled proteins, ask for extra veggies instead of starchy sides, and skip the bread. Most restaurants can accommodate keto requests if you ask.
How do I keep lunch fresh until I eat it?
An insulated lunch bag with an ice pack keeps cold foods safe. For hot foods, preheat a thermos with boiling water before adding your meal.
Should I skip lunch on keto if I do intermittent fasting?
Skipping lunch is optional, not required. If you do intermittent fasting you might eat two meals a day, but if you're hungry, eat. Skipping meals when you're new to keto can backfire and lead to overeating later.
