Best Greek Yogurts UK 2026 — Lowest Calorie & Highest Protein Ranked

Greek yogurt delivers more protein and fewer calories than standard yogurt — making it one of the most effective foods for weight loss available in UK supermarkets.

Greek yogurt is strained to remove liquid whey, which concentrates the protein and reduces the sugar content. A 0% fat plain Greek yogurt typically contains 9–10g of protein and 55–65 kcal per 100g. Standard yogurt contains roughly 5g of protein and more sugar per 100g.

Protein increases satiety and reduces overall calorie intake across the day. Live bacterial cultures — including Lactobacillus bulgaricus and Streptococcus thermophilus — support gut health and digestion. Both factors make Greek yogurt particularly useful for anyone managing their weight.

This guide ranks eight widely available UK Greek yogurts by calories and protein per 100g, identifies the best options by use case, flags the flavoured yogurt calorie trap, and answers the most common questions about Greek yogurt and weight loss.

Why Greek Yogurt Is One of the Best Foods for Weight Loss

Greek yogurt provides more protein per calorie than almost any other dairy food available in UK supermarkets. At 57–65 kcal per 100g for a 0% fat option, Greek yogurt delivers 9–10g of protein — a ratio that few foods match.

Protein reduces appetite by suppressing ghrelin, the hunger hormone. Research published in the American Journal of Clinical Nutrition found that higher-protein meals reduce subsequent calorie intake by up to 20%. Greek yogurt works as a practical delivery mechanism for that protein at low caloric cost.

Live cultures in Greek yogurt support the gut microbiome. A balanced microbiome is associated with better metabolic function and reduced inflammation — both relevant to long-term weight management.

Unlike flavoured yogurts or low-fat alternatives, plain 0% fat Greek yogurt contains no added sugar. The macronutrient profile — high protein, near-zero fat, low sugar — makes Greek yogurt one of the most efficient weight-loss foods in the chilled aisle.

What to Look for on the Label

When choosing a Greek yogurt for weight loss, prioritise protein per 100g, total calories, and sugar content — in that order.

The four metrics to check on the label are listed below. Check per 100g figures — not per serving — because serving sizes vary between brands and comparing per 100g is the only consistent method.

• Protein per 100g: Aim for 9g or above. Anything below 7g indicates a Greek-style product rather than authentic strained yogurt.
• Calories per 100g: Under 65 kcal for 0% fat options. Above 70 kcal suggests added ingredients or full-fat content.
• Total sugar per 100g: Under 5g for plain varieties. Natural lactose accounts for most of this. Above 5g in a plain yogurt indicates added sweetener.
• Total fat per 100g: 0.2–0.3g for 0% fat. Full-fat Greek yogurt contains 8–10g of fat and roughly double the calories.

Live cultures are worth checking too — look for “contains live cultures” on the label. Most authentic Greek yogurts include them; some cheaper Greek-style products do not.

Greek Yogurts Ranked — Calories & Protein per 100g

The table below ranks eight widely available UK Greek yogurts by protein per 100g. All figures are for plain, unsweetened varieties. Flavoured variants are addressed separately below.

*Alpro is plant-based and not Greek yogurt — included as a dairy-free alternative for comparison only.

The top three — Aldi Brooklea, Arla Protein, and Fage Total 0% — deliver 10g or more of protein at under 65 kcal per 100g. Activia 0% and the Tesco Greek Style both score considerably lower on protein despite similar calorie counts, making them weaker choices for weight loss.

Best for Protein / Best for Weight Loss / Best Budget

Different goals call for different choices. The three standout picks from the table above are listed below by use case.

Best for Protein: Aldi Brooklea 0% Authentic Greek Yogurt
Aldi Brooklea contains 10.4g of protein per 100g — the highest of any widely available UK supermarket option. A 500g tub costs around £1.89, giving Aldi Brooklea the best protein-to-price ratio in the UK. Texture is thick and consistent.

Best for Weight Loss: Fage Total 0%
Fage Total 0% scores well on every metric — 57 kcal, 10g protein, and only 3.7g sugar per 100g. Fage Total 0% has a thicker texture than most supermarket alternatives, making Fage Total 0% more satisfying to eat.

Best Budget: Lidl Milbona 0% Fat Greek Yogurt
Lidl Milbona costs under £1.50 per 500g tub. At 55 kcal and 9g protein per 100g, Lidl Milbona delivers solid nutrition at the lowest price point of any option in the table. Texture is slightly thinner than Fage or Brooklea — better suited to smoothies and overnight oats than eating straight.

The Flavoured Yogurt Calorie Trap

Flavoured Greek yogurts contain 30–60% more calories and 2–4 times more sugar than plain equivalents. The word “light” on the label does not change this significantly.

A plain Fage Total 0% contains 57 kcal and 3.7g of sugar per 100g. Fage Total 0% with strawberry contains around 80 kcal and 12g of sugar per 100g. That is three times the sugar for the same brand and format.

Activia flavoured pots regularly exceed 90 kcal per 100g. Yogurts with a fruit compote layer at the bottom add further sugar that sits beneath the yogurt and is easy to miss on the label.

Buy plain. Add your own fruit. A handful of fresh or frozen berries adds roughly 10–15 kcal and less than 3g of sugar — far less than any flavoured variant.

How to Use Greek Yogurt Every Day

Greek yogurt works beyond breakfast. Greek yogurt replaces higher-calorie ingredients in sauces, dips, baking, and snacks — reducing overall calorie intake without changing the texture of the finished dish significantly.

Five practical uses for plain 0% fat Greek yogurt are listed below:

• Breakfast: Combine with oats and fresh berries. Protein from the yogurt slows glucose absorption from the oats and keeps hunger suppressed until lunch.
• Snack: Add a teaspoon of honey and a small handful of walnuts. Total calories: approximately 150 kcal with 12g of protein.
• Sauce base: Replace soured cream or mayonnaise in tzatziki, dips, and jacket potato toppings. Switching from soured cream to 0% Greek yogurt reduces fat by roughly 85% per 100g.
• Baking substitute: Replace butter or oil in muffins and pancake batter at a 1:1 ratio. Greek yogurt reduces the calorie count of a standard muffin recipe by approximately 30%.
• Post-workout: 150g of plain Greek yogurt delivers 15g of protein at under 100 kcal. Greek yogurt requires no preparation and is absorbed quickly.

All five uses apply to plain 0% fat Greek yogurt only. Flavoured varieties add sugar and calories that undermine the calorie savings in each scenario above.
