The In-N-Out Secret Shake Sizes
While the official In-N-Out menu only lists a single shake size, regulars and employees know there are larger options available through the secret menu. The standard shake is a 15-ounce serving, but larger sizes are served in the cups intended for soft drinks. A "large" shake is poured into the medium 22-oz soda cup, while the "extra large" (XL) version is served in the large 32-oz soda cup. This makes the XL shake approximately double the volume of a standard order. The availability of these larger sizes may not be universally known, but asking politely for a large or extra large will usually be accommodated.
Calorie Estimates for an Extra Large Shake
Since In-N-Out does not officially list nutrition information for their secret menu items, the calorie content of an extra large shake must be estimated based on the standard shake's known nutrition facts. A reasonable estimate is to double the calories of the 15-ounce shake to account for the approximately 30-ounce serving size.
Extra Large Vanilla Shake
- A regular 15-ounce vanilla shake contains approximately 580 calories.
- An estimated 30-ounce extra large vanilla shake would therefore contain around 1,160 calories ($580 * 2$).
Extra Large Chocolate Shake
- A regular 15-ounce chocolate shake contains approximately 590 calories.
- An estimated 30-ounce extra large chocolate shake would contain around 1,180 calories ($590 * 2$).
Extra Large Strawberry Shake
- Specific nutritional data for a 30-ounce extra large strawberry shake is available from Verywell Fit, which estimates 1,180 calories for this size.
- This estimate aligns closely with the doubled calories of a regular 15-ounce strawberry shake (around 610 calories).
Health Implications of an Extra Large Shake
Indulging in an extra large shake should be considered a significant caloric and nutritional event. These shakes are not only packed with calories but also high in saturated fat and sugar. A single extra large shake can easily fulfill or exceed half of an average adult's recommended daily caloric intake. The extremely high sugar content, often over 100 grams for a 30-ounce portion, is another major health consideration. While a delicious treat, consuming such a high-calorie beverage regularly is not recommended for a balanced diet and is best reserved for a rare indulgence.
How to Order the Extra Large Shake
Ordering an extra large shake is a simple process for those in the know. You just need to ask for it by name and know which cup it's served in. This simple hack is part of In-N-Out's unofficial charm and a favorite among many regulars. For those wanting to share, it's also a common practice to request an extra cup or two to split the large beverage, saving some money in the process.
Shake Size and Calorie Comparison
Here is a simple comparison of the three shake sizes available via the regular and secret menu:
| Shake Flavor | Standard (15 oz) Calories | XL (30-32 oz) Estimated Calories |
|---|---|---|
| Vanilla | ~580 calories | ~1,160 - 1,240 calories |
| Chocolate | ~590 calories | ~1,180 - 1,260 calories |
| Strawberry | ~590 calories | ~1,180 - 1,260 calories |
Conclusion
For those wondering how many calories is an extra large shake at In-N-Out, the answer is a significant amount: an estimated 1,160 to 1,260 calories, depending on the flavor. This secret menu item is served in the 30 to 32-ounce large soda cup and represents a major indulgence in terms of both calories and sugar. While a tempting treat, it's important to be mindful of its nutritional impact and enjoy it in moderation as part of an overall balanced diet.
