Best Yogurt For Weight Loss
Yogurt can support weight loss when you choose the right type, but not all yogurts are equal. Greek yogurt, Icelandic skyr, and unsweetened natural varieties are high in protein, which helps you feel fuller for longer and supports muscle maintenance during weight loss. The key is avoiding flavoured yogurts loaded with added sugar, which can undermine your weight management efforts. Combined with a balanced diet and increased physical activity, choosing lower-sugar yogurt options is a practical step in your weight loss journey.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Which Yogurts Support Weight Loss Best
Greek yogurt contains almost twice the protein of regular yogurt — typically 15–20g per 100g serving — making it one of the best choices for weight loss. The high protein content increases satiety, meaning you stay fuller longer and are less likely to snack between meals. Icelandic skyr is another excellent option, with even more protein (10g per 100g) and minimal added sugar. Plain, unsweetened yogurt — whether Greek, natural, or set yogurt — is far superior to fruit or flavoured varieties, which often contain 15–25g of added sugar per 100g.
- Greek yogurt: 15–20g protein, 5–8g carbs per 100g
- Icelandic skyr: 10g protein, 3g carbs per 100g
- Plain natural yogurt: 3–4g protein, 4–5g carbs per 100g
- Flavoured yogurt: 3–4g protein, 15–25g carbs per 100g
When selecting yogurt for weight management in the UK, check the nutrition label carefully. Look for varieties with less than 5g of sugar per 100g and at least 5g of protein. Adding your own fresh berries, nuts, or a drizzle of honey gives you control over added sugars whilst boosting nutritional value.

Yogurt In Your Weight Loss Plan
Yogurt works best for weight loss as part of a structured approach to healthy eating. A 150g serving of Greek yogurt makes an excellent high-protein breakfast or snack, supporting appetite control throughout the day. Use our free BMI calculator above to check where you stand, and consider tracking your weight loss progress with our progress tracker — this helps you see the impact of dietary changes over time.
If you're considering more structured weight management — such as prescription weight loss medication like GLP-1 injections — these are always used alongside dietary improvements, not instead of them. Our GLP-1 weight loss calculator can help you understand how medication-supported weight management works in combination with healthy food choices. For personalised nhs weight loss guidance in the UK, always speak with your GP, who can recommend the best approach for your individual health.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is Greek yogurt really better for weight loss than regular yogurt?
Yes — Greek yogurt contains nearly double the protein of regular yogurt, which increases satiety and helps you feel fuller for longer. This makes it easier to stick to a calorie deficit, which is essential for weight loss. The higher protein also helps preserve muscle mass during weight loss.
How much yogurt should I eat per day for weight loss?
A 150–200g serving of plain Greek yogurt per day fits well into most weight loss plans. This provides 20–30g of protein with minimal calories. Avoid eating excessive amounts of any food, even healthy options — portion control remains important for weight management.
Can flavoured yogurts help with weight loss?
Most flavoured yogurts contain 15–25g of added sugar per 100g, which adds unnecessary calories and can spike blood sugar levels. Stick to plain, unsweetened varieties and add your own fruit or honey instead. This gives you control over sugar intake whilst supporting sustainable weight loss.
What's the difference between Greek yogurt and Icelandic skyr?
Both are excellent for weight loss. Icelandic skyr has slightly more protein and fewer carbs than Greek yogurt, making it a marginally better choice if available and affordable. However, plain Greek yogurt is widely available across UK supermarkets and delivers similar weight loss benefits.
Should I use yogurt if I'm taking weight loss medication?
Yes — yogurt fits perfectly into a weight loss plan alongside prescription medication like GLP-1 injections. These medications work best when combined with balanced eating, regular activity, and good nutrition. High-protein foods like Greek yogurt support healthy weight loss whilst maintaining muscle.
