Is Retro Cola Keto?

The Ingredient Breakdown

As a food scientist, I look beyond the marketing claims of "organic" to the molecular structure of the ingredients. While the ingredients list is free from artificial additives, the carbohydrate sources used in Retro Cola are the exact opposite of what a keto dieter needs.

The primary issue is the triple-threat of sweeteners. The product lists organic sugar, organic invert sugar syrup, and organic glucose syrup. Regardless of the "organic" label, sugar (sucrose) and glucose are simple carbohydrates that digest rapidly. On a keto diet, the goal is to limit total carbohydrates to under 20-50 grams per day. A single serving of this cola would consume a significant portion of that allowance immediately.

Additionally, the inclusion of organic corn starch is a major red flag. Corn starch is a highly refined thickener derived from corn endosperm. It is essentially pure glucose polymer. In the context of a ketogenic diet, starches are strictly limited because enzymes in the digestive tract break them down into glucose, causing a sharp insulin response. This ingredient alone disqualifies the beverage from being considered low-carb.

Finally, the presence of organic sunflower oil and organic carnauba wax serves as a processing aid for texture and mouthfeel. While these fats are not carbohydrates, they are often used in sugary beverages to create a specific viscosity that mimics the feel of traditional soda.

Nutritional Value

From a nutritional standpoint, Retro Cola is designed as a treat, not a health food. A standard 12-ounce serving of a full-sugar cola typically contains between 140 and 150 calories, all of which come from carbohydrates. With roughly 39 grams of total carbohydrates per serving, there are zero grams of fiber to subtract, meaning the net carb count is also 39 grams.

For someone following a standard diet, this is comparable to any other soda. However, for a keto dieter, consuming 39 grams of carbs in one drink could exceed their daily limit, effectively halting ketosis. There is no fat or protein in this beverage to provide satiety or sustained energy; it is purely a source of empty calories and rapid sugar.
