The Best Seeds for Keto Ranked by Net Carbs

The ketogenic diet relies on low-carb, high-fat foods to maintain ketosis. Seeds are an excellent choice because they provide healthy fats, fibre, and minimal net carbs. Below, we rank the best seeds for keto based on their net carbohydrate content per 100 g.

Top Seeds for Keto by Net Carbs

1. Chia Seeds

Chia seeds contain just 1.4 g of net carbs per 100 g, making them one of the best options for keto. They’re also rich in omega-3 fatty acids and fibre, which supports digestion and satiety.

2. Flaxseeds

Flaxseeds have 1.5 g of net carbs per 100 g. They’re high in lignans, which may support hormonal balance, and their mild nutty flavour works well in keto baking.

3. Pumpkin Seeds

Pumpkin seeds (pepitas) offer 4.7 g of net carbs per 100 g. They’re a good source of magnesium, which can help with muscle function and electrolyte balance.

4. Sunflower Seeds

Sunflower seeds contain 11.4 g of net carbs per 100 g. While slightly higher in carbs, they’re still keto-friendly in moderation and provide vitamin E.

5. Sesame Seeds

Sesame seeds have 12.2 g of net carbs per 100 g. They’re rich in calcium and work well as a topping for salads or keto-friendly bread.

What This Means in Practice

In the UK, you can find chia seeds at Tesco for £3.50 per 300 g pack. Flaxseeds are often cheaper, priced at £2.20 for 200 g at Aldi. Pumpkin seeds are widely available year-round, making them a convenient choice for adding crunch to meals.

keto-friendly nuts also pair well with seeds for a balanced snack. For those managing insulin resistance, seeds provide slow-digesting fats without spiking blood sugar.

Nutritional Benefits Beyond Carbs

Seeds are nutrient-dense, offering protein, healthy fats, and micronutrients like zinc and selenium. Their high fibre content helps maintain stable blood glucose levels, which is crucial for ketosis.
