How is Repast different from other keto meal planners?

Repast treats your carb cap as a strict mathematical constraint rather than a warning after the fact. Across 16,933 simulated days the carb overage is 0g. Furthermore, all data remains strictly on your iPhone with no account, server, or analytics.

What happens if my dietary constraints cannot be met?

Repast refuses rather than fudges. If your constraints cannot be satisfied (such as 15-minute meals, pescatarian, and no eggs), the app names the exact bottleneck rule and calculates how much loosening it unlocks instead of quietly breaking your rules.

Does Repast require an account or internet connection?

No. Repast operates entirely on your device. There is no account sign-up, no backend server, and no analytics tracking. Your weight, meals, and measurements stay on your iPhone.

How does the shopping list handle leftovers?

The shopping list counts whole cooks rather than individual sittings. Cooking a four-serving recipe eaten twice is counted as one cook session, cutting redundant grocery purchasing.

The Maltitol Trap: Why 'Sugar-Free' Keto Bars Spike Blood Glucose

Maltitol has a glycemic index nearly identical to table sugar, yet brands deduct 100% of it to claim single-digit net carbs. Here is the math of the ultimate keto sweetener fraud.

You find a gourmet 'keto chocolate bar' proudly displaying '2g Net Carbs' on the front wrapper. The back label lists 22g Total Carbs, 2g Fiber, and 18g Sugar Alcohols. The manufacturer simply subtracts the entire 18g of polyols, claiming compliance. But if that sugar alcohol is maltitol, you are effectively eating a standard candy bar.

1. The Glycemic Truth Behind Maltitol

Erythritol has a glycemic index of 0. Allulose is 0. Sucralose is 0.

Maltitol syrup, by contrast, has a glycemic index between 35 and 52. For comparison, table sugar has a GI of 65.

Maltitol is absorbed through the intestinal mucosa and metabolized into glucose, stimulating significant insulin secretion while causing severe osmotic gas and diarrhea when unabsorbed portions reach the colon.

2. The True Net Carb Equation for Maltitol

To calculate the true metabolic impact of maltitol, you must count at least 50% of its grams as active carbohydrates.

That '2g Net Carb' bar with 18g of maltitol actually delivers 11g of true glycemic carbohydrate — enough to immediately suppress hepatic ketone synthesis in sensitive individuals.

THE BOTTOM LINE

Never subtract maltitol from total carbohydrates. Check the ingredient list of every 'sugar-free' treat, and strictly reject any product utilizing maltitol or maltitol syrup.
