This 7-day plan is more than a detox—it’s a reset that helps your body work with you instead of against you.

Why Smoothies Work for Weight Loss

Smoothies aren’t just trendy—they’re science-backed. When made right, smoothies can support fat burning and appetite control while keeping your body satisfied.

• High-fiber ingredients like berries, greens, and chia seeds promote fullness and support digestion.
• Healthy fats from avocado, flax, or nut butters balance blood sugar and curb cravings.
• Protein-rich additions like Greek yogurt, hemp seeds, or clean powders help preserve muscle while losing fat.
• Low-glycemic fruits like berries and green apples reduce insulin spikes that lead to fat storage.
• Hydrating liquids like coconut water and almond milk improve metabolism and reduce water retention.

The key is to skip the sugary, fruit-only blends and go for balanced smoothies that fuel your metabolism, not crash it.
