Mealtimes can be especially challenging if your loved one has unique dietary needs. With so much going on, it's difficult to set aside time for cooking, but you don’t want to scrimp on nutrition either. Enter the low carb meal replacement shake.

High-quality low carb meal replacement shakes provide a healthy complete meal substitute if you’re in a rush. And, if your loved one has diabetes, heart disease, or a metabolic condition, they can drink them without having to worry about a blood sugar spike. 

At Carewell, we stock several types of low carb meal replacement shakes. Keep reading to learn more about our selection and what makes each unique. 

What Are Low Carb Meal Replacement Shakes?

Low carb meal replacement shakes are nutritional drinks formulated for people on low carbohydrate or keto diets. The definition of low carb diet varies, but it typically limits carbohydrate intake to between 20-57 grams of carbohydrates per day

Low carb meal replacement shakes substitute carbohydrates with protein and healthy fats. They’re delicious and filling, and ideal for people with underlying medical conditions who need to maintain a healthy weight. 

What Types of Health Problems Benefit From Low Carb Diets?

Low carb diets are often associated with weight loss, but they provide other health benefits, too. Consider adding them to your pantry, if you care for someone with:

  • Prediabetes

  • Diabetes

  • High cholesterol

  • Hypertension (high blood pressure)

  • Metabolic syndrome

When combined with healthy lifestyle changes, like exercise and stress management, a low carb diet offers various benefits, including lower blood pressure and improved cholesterol levels
