Is Peach Tea grass-fed clear whey isolate Keto?

The Ingredient Breakdown

As a food scientist, I look past the marketing claims and straight at the ingredient deck. The verdict here is driven by one specific ingredient that is a hard stop for the Keto diet.

The primary issue is the presence of cane sugar. Cane sugar is a refined sucrose that contains 4 grams of carbohydrates per teaspoon. On a Keto diet, the goal is to keep net carbs extremely low (usually under 20-50g per day) to maintain a state of ketosis. Adding pure sugar spikes blood glucose and insulin levels, effectively kicking you out of ketosis immediately. It is a non-negotiable exclusion for this diet.

However, the formula isn't all bad. It utilizes Allulose, a rare sugar that behaves similarly to sucrose in baking and taste but has negligible calories and does not impact blood sugar. It is an excellent Keto-friendly sweetener. The product also uses stevia leaf extract and Tebaudioside A (the sweet component of Stevia), which are zero-carb sweeteners. The inclusion of cane sugar alongside these powerful non-nutritive sweeteners is baffling from a formulation standpoint—it suggests a compromise was made for mouthfeel or taste that ultimately ruins the product's diet compatibility.

Finally, citric acid is used to provide the 'tea' tartness, and silica is an anti-caking agent to keep the powder free-flowing. Neither of these impacts the Keto status.

Nutritional Value

From a macronutrient perspective, clear whey isolates are designed to be almost pure protein. This product likely boasts a high protein count with zero fat, which is ideal for the high-protein, moderate-fat requirements of Keto. However, the 'carbs' line item is where the plan falls apart.

Because of the added cane sugar, the total carbohydrate count will be too high for a single serving to fit within a daily Keto limit without sacrificing other meals. Even if the total carbs appear low (e.g., 4-5g), if those carbs are exclusively from added sugar, they are 'empty' carbs that provide no nutritional value and disrupt your metabolic state. For a diet that relies on fat burning, introducing a rapid-burning fuel source like sugar is counterproductive. While the product is low calorie, the source of those calories matters deeply for Keto adherents.
