A certified nutritionist and self-taught chef with a love for entertaining and experimenting with food, Lolita Carrico created Ketology after struggling for years with her own hormonal changes and weight gain. After having two children, she found that managing her weight and moods became more and more of a struggle. After researching the ketogenic diet thoroughly and understanding the science and nutritional aspects, she began her keto journey in 2018. Within three months, she shed 25 pounds and her mood improved, focus sharpened and her energy was through the roof. Four years later, she has maintained a 65-pound weight loss and has learned to intuitively follow a balanced keto lifestyle without sacrificing a thing!

This keto jam is perfect on keto toast, in yogurt or on top of your favorite low carb ice cream! Blackberries are a glorious fruit – I could snack on them all day and thankfully, they are among the fruits that are lowest on the glycemic index, so blackberries are perfect if you?re wanting that fruit fix.?

I love making this keto blackberry jam with a hint of vanilla. The combination of blackberry with vanilla is delicious. I thicken this jam with chia seeds – similar to my chia pudding, the chia seeds expand and have this gelatinous texture that mimics gelatin. Of course, you can simply use gelatin instead of chia, however I prefer the superfood powers of chia and the texture works well with the texture of the berries.?

Benefits of Chia Seeds

In addition to protein and fiber, chia seeds are anti-aging super seeds that are rich in antioxidants and healthy fats. Chia seed oil is actually used in skin care products because it is rich in omega-3 and omega-6 fatty acids and is found to prevent premature skin aging.?

Beyond the beauty benefits, studies have shown that adding chia seeds to your diet may reduce cholesterol and heart disease risks and also support brain health as we age and lowers risk of stroke, Alzheimer?s disease and depression.?
