Yogurt is a nutrient-rich food, a creamy and tasty addition to many meals, offering several health benefits. It is made by combining heated milk with bacteria, which then turn the sugar in the milk (lactose) into lactic acid, thickening the milk and giving it a unique, tart flavor. Yogurt is an excellent source of probiotics, calcium, and protein, as well as vitamins A and B12, calcium, potassium, iodine, phosphorus, and magnesium. These nutrients can help with bone health, maintain healthy blood pressure, and control hypertension.
Nutritional Value of Yogurt
A one-cup serving of low-fat, plain yogurt contains 154 calories, 13 grams of protein, 4 grams of fat, 17 grams of carbohydrates, 0 grams of fiber, and 17 grams of sugar. It provides 40% of the daily recommended intake (DRI) of calcium and 50% of the DRI of potassium, phosphorus, and magnesium.
Portion sizes of yogurt should be considered in relation to fat content, as yogurt can be made with nonfat milk, 2% milk, or whole milk, affecting the calorie count. Consuming one to two cups of plain low-fat yogurt daily can be a healthy addition to your diet without hindering weight management.
Types of Yogurt
There are various types of yogurt available, including:
- Traditional Yogurt: Unstrained and creamier, available in nonfat or low-fat versions. Nondairy options made from coconut, soy, or almond milk are also available.
- Skyr Yogurt: A traditional Icelandic yogurt made from skim milk, strained to create a thicker, creamier texture with a high protein content.
- Greek Yogurt: Strained to remove extra liquid and whey, resulting in a thicker, denser yogurt with a higher concentration of probiotics and protein. It is typically lower in sugar, carbs, and calories, and is a great source of iodine and vitamin B12.
- Kefir Yogurt: A drinkable yogurt made from fermenting milk and adding kefir grains. It undergoes a longer fermentation process, resulting in a tart taste and slightly bubbled texture. Kefir yogurt has a reduced amount of lactose and is a stronger probiotic than regular yogurt.
- French Yogurt: Unstrained yogurt made from pasteurized milk, cane sugar, and active cultures, cultured directly in individual jars. It has a thick texture, is less sweet with fewer carbohydrates, but contains more fat.
- Frozen Yogurt: Made from milk fermented with live bacteria cultures, but typically includes sugar, flavorings, stabilizers, and cream. It can be a healthier alternative to ice cream but may contain an equal amount of sugar.
- Probiotic Yogurt: Contains specific bacteria strains that help maintain the balance of good bacteria in the body, aiding in digestion and nutrient absorption.

Probiotics and Weight Loss: The Research
Probiotics are live microorganisms that have health benefits when eaten. They’re found in both supplements and fermented foods. Studies have found that probiotics may improve your immune function and digestive and heart health, among other benefits. Researchers have found that probiotics may improve your immune function and digestive and heart health. Hundreds of microorganisms reside in your digestive system.
How Probiotics May Aid Weight Loss
- Influence on Appetite and Energy Usage: Studies suggest that probiotics seem to influence appetite and energy usage via the production of acetate, propionate, and butyrate, which are short-chain fatty acids.
- Inhibition of Dietary Fat Absorption: Studies have found that certain probiotics may inhibit the absorption of dietary fat, decreasing inflammation and increasing the amount of fat excreted with feces.
- Release of Appetite-Regulating Hormones: Probiotics may help release the appetite-reducing hormones glucagon-like peptide-1 (GLP-1) and peptide YY (PYY).
- Increase Levels of Fat-Regulating Proteins: Research has also found that probiotics may increase levels of the protein angiopoietin-like 4 (ANGPTL4).
Specific Probiotic Strains and Weight Loss
- Lactobacillus Gasseri: Researchers have found that Lactobacillus gasseri shows promising effects on weight loss in humans. It decreased body weight, BMI, waist circumference, body fat mass or fat percentage in those with overweight or obesity.
- Other Strains: Several strains of probiotics in both the Lactobacillus and Bifidobacterium family have been shown to reduce weight.
Probiotics and Weight Gain Prevention
Taking a probiotic formulation called VSL#3 prevented weight gain and insulin resistance in mice. This indicates that some probiotic strains might have the same effect in humans.
