Myth Busters
MYTH #1: Keto Protein Bars Are Unhealthy Processed Foods
TRUTH: think! Keto Bars use clean ingredients — whey protein isolate, peanuts, cocoa butter, and chicory root fiber. High-protein snack bars have been shown to improve short-term glucose and insulin profiles compared to high-fat alternatives without protein.
MYTH #2: Sugar Alcohols in Keto Bars Spike Blood Sugar
TRUTH: Erythritol, the primary sugar alcohol in think! Bars, has a glycemic index of 0 and does not raise blood sugar or insulin levels. It passes through the body largely unmetabolized, unlike maltitol or sorbitol.
MYTH #3: 10g Protein Per Bar Is Not Enough
TRUTH: Research shows 20-25g of high-quality protein maximally stimulates muscle protein synthesis per meal. At 10g of whey protein isolate, one think! Bar provides a meaningful contribution toward this threshold, especially as a between-meal snack.
MYTH #4: High-Fat Bars Cause Weight Gain
TRUTH: The 14g of fat in think! Keto Bars come primarily from peanuts and cocoa butter — sources of monounsaturated and saturated fats that promote satiety. Ketogenic diets have been shown to support weight loss and appetite control when total calorie intake is managed.
MYTH #5: Keto Bars Are Just Candy Bars in Disguise
TRUTH: Unlike candy bars (25-35g sugar per serving), think! Keto Bars contain only 2g sugar. The sweetness comes from erythritol and stevia — natural sweeteners with zero glycemic impact. No artificial sweeteners like sucralose or aspartame are used.
NutriScore by Health Goals
| Health Goal | NutriScore | Why This Score? |
|---|---|---|
| Weight Loss |  | 180 calories with 10g protein and 3g fiber promotes fullness. Only 4g net carbs supports ketogenic fat burning. |
| Muscle Gain |  | 10g whey protein supports muscle protein synthesis but falls short of the 20-25g optimal post-workout dose. Best as a supplementary snack. |

| PCOS Management | | Low sugar and low net carbs reduce insulin spikes. High-fat, moderate-protein ratio supports hormonal balance on keto protocols. |
| Pregnancy Nutrition |  | Contains erythritol — limited data on safety during pregnancy. Ketogenic diets not recommended during pregnancy. Consult your doctor. |
| Viral/Flu Recovery | | Provides 10g protein for immune support and easy-to-consume energy. Low in vitamins and micronutrients compared to whole foods. |
