Cheapest Gluten-Free, Keto & Vegan Foods at Walmart

How Much Does a Gluten-Free Diet Cost Per Week?

The average American spends $80-$100 per week on groceries. Switching to a gluten-free diet typically adds 20-30% to that cost — roughly $95-$130 per week. The biggest price jumps are in bread ($0.36/oz vs $0.12/oz for regular), pasta, and baking mixes. But smart shoppers can reduce this premium by buying store brands like Great Value, choosing bulk sizes, and focusing on naturally gluten-free staples like rice, oats, and corn-based products that cost under $0.10/oz.

Keto Grocery Budget: What to Expect at Walmart

Keto diets shift spending from carbs to fats and proteins — budget $85-$120 per week at Walmart. Specialty keto products (bars, baking mixes, sugar-free snacks) are expensive at $0.80-$1.50/oz. The hack: skip branded keto products and buy base ingredients. Great Value butter, cheese, eggs, and bulk nuts deliver the same macros at 30-50% lower cost. Our calculator shows exactly how many keto-friendly products your budget covers.

Vegan Grocery Budget: Walmart's Best Deals

Vegan diets can be the cheapest or most expensive depending on what you buy. Base staples (beans, rice, oats, lentils) cost as little as $0.05-$0.08/oz — making a $50/week vegan budget very achievable. But plant-based meat alternatives ($0.50-$0.75/oz) and specialty vegan cheese ($0.80-$1.20/oz) can push the budget past $120/week. Use our calculator to find the sweet spot for your budget.
