Compared to some of the crazy-strict diets out there, you might find that a low-sugar diet is the most “user-friendly,” healthy, and sustainable of all of them. But if you’re looking for one that’s a similar alternative to a low-sugar diet, we think these are some of the best options.

Ketogenic Diet

The ketogenic diet is low sugar taken to the extreme. In addition to reducing added sugars to virtually nothing, you also have to reduce carb intake to no more than 10 percent of your daily calories. This would cut out added sugars, as well as almost all naturally occurring ones in fruit, dairy, whole grains, and even some vegetables. If you’re up for the challenge, make these delicious ketogenic breakfasts to get you going in the morning.

Paleo Diet

The Paleo diet cuts out added sugars but also eliminates some sources of natural sugars like dairy and whole grains.Thankfully it’s not totally low-carb, as you can still enjoy something sweet in your favorite fresh fruits and veggies. Paleo also lets you get away with making Paleo-approved desserts that are often made with maple syrup, honey, and dates, so you’ll be able to satisfy a nagging sweet tooth.

Atkins Diet

Like the ketogenic diet (but less sexy), Atkins is a classic low-carb, high-protein diet. Not only will you need to cut back on added sugars, but all sources of carbs (like grains, fruit, and some starchy veggies) are severely restricted.

Whole30 Diet

The Whole30 diet cuts out all added sugars (even honey and maple syrup) along with sources of natural sugars like dairy and whole grains. You’re allowed to eat fruit and starchy veggies, so like the Paleo diet, it’s not technically low-carb, but unlike Paleo, you can’t enjoy any desserts so you can forget about making “healthy” brownies.

Dukan Diet

The Dukan is a phase-based diet that gets less restrictive as one goes on, but the common theme throughout is to eliminate added sugars. The first phase is limited to eating just natural protein, while the next phase adds small amounts of fruit, whole grains, starches, and cheese. For this reason, the Dukan Diet is practically a quick-fix coupled with a long-term commitment to reducing added sugars.
