Lowest Calorie Fruit Juices for Weight Loss

The lowest calorie fruit juice is typically cucumber juice, with about 16 calories per 100ml, making it a refreshing, low-calorie option.

Fruit juices can be a refreshing way to stay hydrated while getting essential vitamins. However, many are high in sugar and calories. If you’re watching your calorie intake, choosing the right juice matters. Here’s a detailed guide to the lowest-calorie fruit juices that won’t derail your diet.

What Makes a Juice Low-Calorie?

Low-calorie juices typically have:

• High water content
• Low natural sugar levels
• No added sugars
• Minimal processing

How Processing Affects Calories

Cold-pressed juices retain more nutrients but may have similar calorie counts to regular juice. For the healthiest option, consider making juice at home with a quality cold press juicer.
