Late nighttime eating doesn’t necessarily mean weight loss, and that applies not just to food, but also to drinks. High-calorie, sugary, or nutrient-poor drinks can quickly add up without leaving you feeling full. So, choosing the right evening beverage is crucial if you want to lose weight effectively.
One of the best options is unsweetened kefir, a nutrient-rich fermented yogurt drink. Kefir has a smooth, creamy, and delicious texture, and is packed with nutrients that help support weight loss, improve digestion, and maintain gut health.
How does kefir help you lose weight?
Here are 3 reasons:
1. It provides high-quality protein
Protein is important for building and maintaining lean muscle, while also helping your body burn calories and control hunger. One cup of kefir contains about 9 grams of protein, including whey and casein. Casein is particularly effective when consumed before bed, helping to repair muscles overnight, boost metabolism and aid in fat loss.
2. Natural source of probiotics
Kefir contains beneficial bacteria (probiotics) that help balance the gut microbiome. Research shows that gut health can influence weight and obesity. Regular consumption of kefir helps support digestion, boost immunity and manage weight naturally.
3. Reduce bloating, support a feeling of relief
Kefir is a rich source of potassium, a mineral that helps balance sodium, limit water retention and bloating. Although it does not directly burn fat, reducing bloating helps you wake up feeling lighter and more comfortable.

How to drink kefir to lose weight effectively
Includes the following tips:
- Drink before bed: A 150–200ml cup of kefir before bed helps the body burn calories and restore muscles throughout the night thanks to casein protein.
- No added sugar: Drink plain kefir or add a few slices of fresh fruit such as strawberries or blueberries to enhance the flavor without increasing the calories.
- Combine with a light dinner: If you eat late at night, choose a light meal rich in protein and vegetables, then drink kefir to increase satiety and aid digestion.
- Maintain regularly: Drink kefir 3–5 times a week to create a habit, help balance the gut and support long-term weight loss.
- Can be combined with smoothies: Mix kefir with fiber-rich fruits, chia seeds or oats to create a nutritious smoothie, help you feel full longer and increase weight loss effectiveness.
Things to keep in mind
Before you drink, keep the following in mind:
- Watch your calories: Prioritize low-calorie or zero-calorie drinks. Added sugars in drinks often add up quickly without providing nutrition.
- Find your nutrition: Choose drinks rich in protein or probiotics, such as kefir, cow’s milk, unsweetened soy milk.
- Boost your protein: Protein helps you stay full longer and supports your muscles. If you want, you can add plant-based protein to diversify your diet.
- Add fiber: Fiber-rich smoothies, combined with kefir or vegetables, help you feel fuller for longer and aid digestion.
- Avoid added sugars: Check the nutrition label to make sure the drink does not contain artificial sugars or added sweeteners.
In short, unsweetened kefir is an ideal choice for a weight-loss-supporting nighttime drink. With protein, probiotics, and potassium, it helps you control your weight, improve digestion, reduce bloating, and increase energy. When taken properly (before bed or combined with a light dinner) kefir becomes an important part of a healthy diet, effectively helping to lose fat and improve overall health.
