Because some fruits have more carbs than others, knowing which to avoid is key for accelerating weight loss and reaping other possible benefits of keto. Just know that large, long-term, randomized controlled trials on the keto diet are limited, so it’s unclear whether keto is safe and effective to follow for the long haul, according to Harvard Medical School.
Lemons are also keto-friendly, so go ahead and add a spritz of lemon juice to your ice water. One typical lemon wedge has about 0.5 g of net carbohydrates and only 0.2 g of sugar. The fruit also offers 3.7 mg of vitamin C, which is 6.2 percent of the DV. Lemon water contains antioxidants that fight free radicals, and it also promotes healthy digestion, according to the Cleveland Clinic.
