Some HMR products, such as HMR Shakes and HMR Entrees, contain high amounts of carbohydrates, making it difficult to incorporate them into a ketogenic diet. However, other HMR products, like the HMR 70 Plus Shakes, have fewer carbs and may be more suitable for a keto diet. As with any diet, it's important to read labels and consult with a healthcare provider before making any significant changes to your diet.
