Can the Keto Diet Be Sustainable?

Keto can be amazing for helping with weight loss, but this fat-centric diet is definitely not light on the environment. The keto diet notoriously limits carbohydrate intake to under 50 grams a day (the equivalent of two medium bananas), forcing your body to burn fat for fuel instead of carbs.

Because it is so carb restrictive, dieters tend to consume huge amounts of proteins and fats (along with some leafy greens). For most people, that means a lot of cottage cheese, beef, eggs, cheese, butter, dairy yogurt and other animal products.

Yep, it’s a heavy diet, in all senses of the word.

The Trouble with Keto

Eating a lot of animal products is bad for the environment—especially if you can’t prioritize local and pastured products that have a lighter footprint (but tend to be a lot more expensive).

People tend to eat A LOT of animal products on the keto diet. This might leave you wondering, is it possible to enjoy the fat-burning benefits of the ketogenic diet while still eating sustainably?

Enter Eco-Keto

Yes, eco-keto is an even more restrictive version of the keto diet, but it might be what you need if you want to benefit from a stint on the keto diet without sacrificing your eco values.

Making the Perfect Low Carb Omelette

So, What’s Off-Limits?

The keto diet is notoriously restrictive already, so don’t expect it to be easy. This version of the diet severely limits animals products, which may leave you scratching your head. What do you eat without animal proteins, cheese, or butter?

Eco-keto is more or less a vegan take on the keto diet. But, unlike a vegan diet, this diet also cuts out a lot of plant-based protein staples, like beans and tofu (too starchy). It’s slim pickings.

What You Eat on Eco-Keto

  • lots of plant-based fats like, avocado, coconut and olives
  • nuts and seeds for protein, especially high fat nuts like walnuts, macadamia nuts and pili nuts
  • some vegans proteins, like pea protein
  • plenty of non-starchy vegetables: cauliflower, kale, spinach, collard greens cabbage

That’s mostly it. So yes, you’ll lose weight. And yes, if you’re buying your produce consciously, it can be much more environmentally friendly. But it takes A LOT of dedication to stick to this diet long-term.

Be aware that even keto proponents recommend that you only follow the keto (or eco-keto) diet for a few months at a time. Eating a highly restrictive diet like keto long-term can cause your body to become stressed, imbalanced and deficient in valuable micronutrients.

Sure, keto can be beneficial for some people in short stints, but it’s not recommended as a lifestyle choice. From a health perspective, it’s never great to cut out macronutrients, like carbs. But if you’re up for a short-term challenge, eco-keto is the cleanest way to get your body into ketosis. (Definitely consult your doctor beforehand, though.)
