- ✓No synthetic stimulants — won't cause jitters or crashes
- ✓90-day money-back guarantee reduces financial risk

- ✓Complete meal plan removes daily decision-making about food
- ✓Instant digital access — no waiting for shipping

- ✗Not truly sustainable long-term — most people can't (and shouldn't) replace meals with smoothies indefinitely
