On a ketogenic diet, you’re going to limit your carbs to 5% or less. Those carbs will come from vegetables, nuts, and dairy. Gone from your diet will be wheat (bread, pasta, cereals), starches (potatoes, beans, legumes), and fruit.
Here’s the stuff to avoid:
Grains – wheat, rice, corn
Sugar – honey, agave, maple syrup, sugar (just in case you needed to hear it)
Tubers – potatoes and yams
Fruit – apples, oranges, and bananas
