Green smoothies combine leafy vegetables with fruits and liquids like water or almond milk.

Popular greens include:

• Spinach
• Kale
• Cucumber
• Celery

These smoothies are often:

• High in fiber
• Rich in nutrients
• Low in calories
• Filling and satisfying

Fiber helps slow digestion and may reduce hunger between meals.

Bonus: Black Coffee

Black coffee is another popular metabolism-support drink because of its caffeine content.

Caffeine may temporarily:

• Increase alertness
• Boost energy
• Slightly raise calorie burning

Black coffee is naturally very low in calories—as long as large amounts of sugar, syrups, and cream are avoided.

Important:

Too much caffeine can cause:

• Anxiety
• Nervousness
• Poor sleep
• Rapid heartbeat

Moderation matters.
