Embracing a Low Carb and Keto Lifestyle: A Mom’s Guide to Health and Wellness

Today, let’s delve into a topic that’s been making waves in the wellness world – the low carb and ketogenic (or keto) lifestyle. If you’ve been curious about what these diets entail and the benefits they offer, you’re in the right place!

Understanding Low Carb and Keto Diets

A low carb diet involves reducing the intake of carbohydrates and replacing them with proteins and healthy fats. The keto diet is a more specific type of low carb diet that focuses on consuming high amounts of fats, moderate proteins, and very low carbs. This combination pushes your body into a state of ketosis, where it burns fat for energy instead of carbs.

Benefits of a Low Carb and Keto Lifestyle

1. Weight Loss: One of the most well-known benefits of a low carb and keto lifestyle is weight loss. By burning fat for energy, your body can shed excess weight more efficiently. Plus, high protein and fat foods can keep you feeling full longer, reducing the urge to snack and helping to control calorie intake.

2. Improved Heart Health: Contrary to what you might think, a low carb and keto lifestyle can actually improve heart health. Consuming healthy fats can help lower bad cholesterol levels and increase good cholesterol levels, reducing the risk of heart disease.

3. Enhanced Brain Function: Some people following a keto diet report improved focus and mental clarity. This is because your brain can use ketones, produced during ketosis, more efficiently than it can use glucose.

4. Stable Blood Sugar Levels: By reducing your carb intake, you can help keep your blood sugar levels more stable, which is particularly beneficial for those with diabetes or insulin resistance.

5. Increased Energy: Once your body adjusts to burning fat for energy, you may find you have more sustained energy throughout the day, without the crashes associated with high-carb diets.

Remember, while a low carb and keto lifestyle can offer numerous benefits, it’s important to approach it in a balanced and healthy way. Always prioritize nutrient-dense foods and listen to your body’s needs. And as with any major dietary changes, it’s a good idea to consult with a healthcare provider or a nutritionist. A low carb and keto lifestyle can be a powerful tool for improving health and wellness. Whether you’re looking to lose weight, boost your energy, or simply feel better overall, it might be worth exploring.

Is a Keto Tuna Casserole with Broccoli Healthy?

One question that often pops up in our quest for healthy, family-friendly meals is about the nutritional value of specific dishes. Today, let’s tackle a popular one: Is a Keto Tuna Casserole with Broccoli healthy?

The short answer is yes, but let’s dive a little deeper to understand why.

The Power of Keto

As we’ve discussed before, a ketogenic (or keto) diet focuses on high-fat, moderate-protein, and very low-carb foods. This approach can offer numerous health benefits, from weight loss to improved heart health and brain function. But what does this mean for our beloved tuna casserole?

Tuna: A Nutritional Powerhouse

Tuna is a fantastic source of high-quality protein, which is essential for maintaining muscle mass and keeping us feeling full and satisfied. It’s also rich in omega-3 fatty acids, which are great for heart health. Plus, it provides a good dose of essential vitamins and minerals, including vitamin D and selenium.

Broccoli: The Green Superstar

Broccoli is a nutritional superstar, packed with vitamins A, C, and K, as well as fiber and potassium. It’s a low-carb vegetable, making it a great choice for a keto diet. Plus, it adds a lovely crunch and vibrant color to your casserole!

The Keto Twist

A traditional tuna casserole often includes high-carb ingredients like pasta or breadcrumbs. In a keto version, these are replaced with low-carb alternatives, such as almond flour or cauliflower rice. This switch not only makes the dish keto-friendly but also increases its nutritional value.

The Verdict

So, is a Keto Tuna Casserole with Broccoli healthy? Absolutely! It’s a balanced meal that combines high-quality protein from tuna, healthy fats (especially if you’re using a creamy, high-fat sauce), and the nutritional powerhouse that is broccoli. It’s a dish that will keep you and your family feeling satisfied, while also fitting into a low-carb, keto lifestyle. Remember, as with any diet, variety is key. Enjoy your Keto Tuna Casserole with Broccoli as part of a diverse diet that includes a range of different proteins, fats, and low-carb vegetables.

Low Carb & Keto Broccoli Tuna Casserole Bake

This Low Carb Broccoli Tuna Casserole Bake is a special request for my dad. He loves tuna casseroles and is really trying to eat healthier these days along with our whole family. I made a similar recipe for Thanksgiving that was just a broccoli casserole. This adds in some great protein from the tuna (or salmon) to get good Omega-3 fatty acids into your diet.

I love broccoli. I love it in casseroles, in stir-fries, and as a simple side dish. Broccoli is so healthy for your too, full of vitamins and minerals.

I’m also a new fan of cauliflower. We eat it if not every night now, every other night. It is so flexible and can become anything you want it to be. Did you know you can even make a pizza crust from a cauliflower? I know… It is pretty amazing.

This is a pretty easy throw together meal too. Mix everything in a bowl and just spread it over your broccoli and cauliflower. Top with cheese, because cheese makes everything better. I shred my cheese in my  Food Processor. It saves me money and I don’t get the filler ingredients added.

  1. Angela, this looks SO good! I am also a recent convert to cauliflower (it was the cauliflower pizza crust that has been making the rounds in blogland that convinced me). So excited to try this recipe because it has broccoli too!

    • Yum! I love cauliflower pizza… so so yummy. My daughter is all about broccoli right now (she’s 3 so anything to get her to eat her vegetables is a double plus). I loved how easy this was to make too. Thanks for leaving me a message!

  2. Oh that looks good! Do you think I could just sub more mayo in place of the cream cheese? We don’t eat any dairy. I can easily leave the cheese of the top, but I’ll have to sub the cream cheese with something. Anyway, I will definitely try something because this looks great. 🙂

  3. Looks like a easy healthy recipe for a one dish meal. Thanks for sharing on Real Food Friday Blog Hop. Always love your recipe Angela. Have a wonderful healthy day!

  4. This sounds like a yummy way to have a tuna casserole. We’re big fans of casseroles, too because they’re easy to make and can feed a lot of people.

    Thanks for linking up at the Pinterest Foodie Party!

  5. It looks so yummy and makes me very hungry right now. It is very healthy as well. Thank you for sharing.

  6. YUMMY! I’m sending this to Dad. He has diabetes and is always looking for low carb or carb free dishes. Thank you for linking up with the Wake Up Wednesday Linky! Stop back next week to see if you’re featured.

    • My dad loves tuna.. haha. So this was a winner for him : ) I love that eating low carb doesn’t have to be boring grilled chicken salads. Thanks for your comment!

    I have also made this substituting canned chicken. The flavor is just as tasty. Thank you for this quick weeknight dinner.

  8. This was a GINORMOUS hit tonight! All three kids and my husband asked for seconds. I used fresh broccoli and cauliflower and this meal could not have been easier or quicker to put together! Thank you for a delicous, easy, and fantastic recipe!!

  9. Can you believe this is low carb??? Low Carb Broccoli Tuna Casserole Bake - Grassfed Mama - Also Kitchen says:

    […] Via: grassfedmama.com […]

  10. Do you the nutritional for this dis? Well mainly want to know how menu carbs are in this dish… Looks yummy!!

  11. Do you have any ideas on the nutritional values of the ingredients ?
    I log all of my meals, and try to keep below 60 Carbs per meal. Also,
    what are we talking here on serving size ? It sounds yummy …….
    Can’t wait to try it! Thanks for posting the recipe. Sorry I didn’t catch
    the other requests for the nutritional values, but I did not see an answer
    to the questions. Maybe it was sent privately ? If so, could you please
    clue me in on what they are ?

    Thanks Stella

    Posting here because this is now a go to recipe for me, I actually have my latest in the oven right now. Thanks so much for posting this!!! Such a great regular low carb meal. I have put my own personal touches on this:

    1) I use an onion and herb seasoning instead of celery seed, haven’t got around to picking up that particular seasoning
    2) I use about double the garlic, sometimes I use fresh instead of powder (I love garlic)
    3) I use heavy whipping cream instead of mayo (never been a big mayo fan)
    4) I love my vegetables, so I usually roughly chop 3-4 different types of vegetables that go well with the other ingredients and throw them into the food processor, pulverizing them with whipping cream before mixing with the tuna/salmon and cream cheese. Tonight I used leftover pieces of eggplant, celery, red onion and green capsicum. Previously I’ve also used mushroom and zucchini, whatever veg I have around usually. I’ve never had a bad result doing this. Though it can be a bit of a balancing act getting all the ingredients not to spill over the top of the casserole dish, I just poke the broccoli and cauliflower until enough of the mixture seeps through to make room for all of it.

    Thanks again for sharing!

    I tried this tonight and was BLOWN away!!!! I didn’t have quite enough cream cheese, maybe 6 ounces, and I also used mixed broccoli, cauliflower, carrots and zucchini! But, all the rest was exactly as written!
    I ABSOLUTELY LOVE IT! I wanted to eat the whole thing myself, but had to share with my husband….who also wanted to eat the whole thing! hahahaha Thank you so much! DELISH!!!!!

    This casserole is so delicious! I make it all the time– it’s great with even chicken or another type of fish. It’s a great way to eat more greens as well. If you’re low carb, do yourself a favour and try this recipe!

  15. I’d really like to make this and am wondering how leftovers would freeze….? I live solo and while I’m sure I could cut the recipe in half, it’s also great to have things waiting in the freezer for nights I don’t want to cook.

    Thanks!

  16. Would you please email me how many net carbs per serving for this tuna broccoli casserole. It sounds so good. I can’t wait to make it. Thank you.

    • Hi Lorie!

      I haven’t done the calculations on this specifically (or I would be happy to send it to you!). If you are able to come up with it when you try I’d love to see what you arrive at!

      Hope you enjoy it!

  17. All that cheese—-hard to imagine this is low carb; please add nutritional analysis. Sounds yummy;but I REALLY have to know carb count and serving size.
    Thank you

    • Hey Robin!

      I haven’t done a full analysis of the dish (though if you end up trying it I’d love to see your numbers!).

      2 Cups of Shredded Cheddar Cheese is less than 3 Grams so that’s the whole dish. Obviously there is some fat content in the cheese but the carb value is quite low. You could also cut down on the amount of cheese if you wanted to further lower the fat content (it’s just for topping so it’s up to you on how heavy you go).

      I hope you give it a try and it works out for you! 🙂

  19. I notice many people asked for the net carbs for this amazing recipe.
    I make it all the time and did a bit of research, surveying the carb count of different brands of ingredients and calculating the average. Total carbs are 45g, 6 serves at 7.5g each.
    (This assumes 500g broccoli and 250g cauliflower. In my house we are pigs and still manage to get 5-6 serves out of it. I sometimes add extra tuna as well, which doesn’t contibute to the carb count.)”

    This was delicious and so easy to throw together. I only had broccoli so that is what I used. My picky daughter is not a fan of broccoli, but to my surprise, went back for seconds! This recipe is a keeper.

  21. I omitted the pepper flakes and used a can of salmon, drained. I don’t remove the bones or skin. I also backed the mayo off to 1/2 cup. Let me first say, the salmon mixture spread is MY NEW FAVORITE SALMON DIP RECIPE! Also, as a constructed casserole, EXCELLENT. I’m anxious to see what the husband thinks. I can’t wait to have my lunch serving tomorrow at work. ?

  22. I love this tuna broccoli casserole! I found the recipe a few years ago and I’ve made it many times. I’ve got one one in the oven right now. Thank you so much!!
