Is Reese's OUTRAGEOUS! Keto?
If you are strictly following a ketogenic diet, you need to put the Reese's OUTRAGEOUS! bar back on the shelf. The direct answer is no; this candy is the metabolic opposite of what a keto diet requires. While it packs a punch in flavor, it is loaded with high-glycemic sweeteners and starches that will instantly spike your blood sugar and insulin levels.
The Ingredient Breakdown
As a food scientist, looking at the ingredient list for Reese's OUTRAGEOUS! reveals a formulation designed for maximum sweetness and shelf stability, not metabolic health. The primary issue for the keto diet is the sheer volume of carbohydrates hidden in the sweeteners and fillers.
The first red flag is the dominance of sugar and corn syrup. In the standard Reese's formula, sugar is the second ingredient, immediately following the milk fat. Corn syrup appears in the caramel fudge variegate. These are pure carbohydrates that have a glycemic index of 100, meaning they digest rapidly and raise blood glucose immediately.
Furthermore, the product utilizes dextrose and corn starch. Dextrose is a form of sugar derived from corn that is even faster to absorb than table sugar. Corn starch is a thickener that breaks down into glucose in the body. Even the Reese's Pieces included in this bar are a danger zone, containing corn syrup solids and vegetable oils like partially hydrogenated palm kernel oil.
Finally, the mono and diglycerides and soy lecithin are emulsifiers used to keep the fats and sugars mixed. While these are technically low in carbs, they are often derived from soy or vegetable oils which many keto purists prefer to avoid due to inflammation concerns. The verdict is clear: the carb count here is far too high to maintain a state of ketosis.
Nutritional Value
From a nutritional standpoint, Reese's OUTRAGEOUS! is a high-calorie, high-sugar treat. A single serving contains a massive amount of sugar—often exceeding 20 to 30 grams per bar depending on the specific size. On a standard keto diet, the daily limit for net carbs is usually between 20 and 50 grams. Eating one of these bars could consume your entire carbohydrate allowance for the day in a single sitting.
While the product does contain peanuts and milkfat, which provide some fat and protein, the ratio is wrong for keto. The high sugar content overwhelms the macronutrient profile. The presence of high fructose corn syrup is particularly concerning because fructose is metabolized differently than glucose, primarily processing in the liver and being more likely to convert to fat (lipogenesis) if not burned for energy.
Additionally, the inclusion of artificial colors like Yellow 5, Yellow 6, and Red 40 Lake (found in the Reese's Pieces) are additives that many health-conscious consumers try to limit. While these don't contain carbs, they contribute to the 'ultra-processed' nature of the food. If you are tracking your macros, the carb density of this bar makes it incompatible with a ketogenic lifestyle.
