Is acorn squash keto-friendly?
So how does acorn squash fit into a keto diet? Let’s take a look.
A ketogenic or “keto” diet typically limits net carbs to 20-50 grams per day. This stimulates ketone production and pushes the body into a metabolic state called ketosis.
With 18.2 net carbs in just 1 cup, acorn squash can quickly use up a good chunk of your daily carb limit. However, acorn squash is not pure carbohydrates. It also provides 2.8 grams of fiber in each cup.
Fiber does not raise blood sugar or insulin levels like carbs do. It also promotes feelings of fullness and supports digestive health. Experts suggest counting only half the grams of fiber towards your daily carb limit.
So in reality, 1 cup of acorn squash contains about 15 net digestible carbs. This amount can be incorporated into a 50-gram net carb keto diet without kicking you out of ketosis. Smaller portions of acorn squash can also work for people following a stricter 20-30 gram daily carb limit.
Additionally, acorn squash is low in sugar compared to many other fruits and vegetables. It has a very low glycemic impact and won’t spike your blood sugar.
Tips for fitting acorn squash into your keto diet
Here are some tips for enjoying acorn squash on keto:
– Stick to 1/2-1 cup portions to keep net carbs in check
– Pair it with lower carb foods like meat, eggs, or non-starchy veggies
– Add fats like butter or olive oil to help slow carb absorption
– Bake, roast, or stuff and cook acorn squash rather than boiling to maximize nutrition
– Substitute higher carb starchy veggies like potatoes with acorn squash
– Save acorn squash for days when you have more carb allowance
As long as you account for the carbs, acorn squash can be a nutritious plant-based addition to a well-formulated ketogenic diet. Monitor your individual carb tolerance to see what portion sizes work for you.
Keto-friendly ways to eat acorn squash
Here are some delicious keto-friendly recipe ideas for enjoying acorn squash:
