Pret Keto Picks That Actually Fit Macros

Eating out on a ketogenic diet requires scrutiny of ingredients and macros. Pret a Manger, the UK’s ubiquitous grab-and-go chain, offers several options that align with low-carb principles when chosen carefully. These selections avoid the blood sugar spikes of their famously carb-heavy baguettes while providing adequate fat and protein.

How to identify keto-friendly Pret meals

Pret’s nutritional information, available online and in-store, lists total carbohydrates and fibre. Subtract fibre from total carbs to calculate net carbs—the figure that matters for ketosis. Aim for under 10g net carbs per meal to stay within typical daily limits of 20-50g. Watch for hidden sugars in dressings and cured meats.

Paoli et al. (2013) note in the European Journal of Clinical Nutrition that very-low-carbohydrate diets induce ketosis most reliably when net carbs remain below 50g daily. Their review found consistent metabolic adaptation when carbohydrate intake stays in this range.

Breakfast options under 5g net carbs

Pret’s Protein Pots range provides the most reliable morning choices. The Cheddar & Chive Protein Pot (£3.25) contains just 3.8g net carbs with 18g protein and 22g fat—an ideal keto ratio. Pair it with black coffee (0g carbs) or an americano with double cream (1.2g carbs). Avoid the yoghurt pots and granola, which exceed 20g net carbs per serving.

keto coffee creamers can transform Pret’s basic coffee into a fat-rich drink. A splash of double cream adds negligible carbs while increasing satiety.

Lunch selections with 10g or fewer net carbs

The Chicken & Bacon Protein Bowl (£6.50) delivers 7.6g net carbs alongside 36g protein. Request it without the honey mustard dressing (adds 5g sugar) and opt for mayonnaise instead. The Super Ham & Egg Salad (£5.20) comes in at 6.2g net carbs when you skip the croutons. Both make substantial meals that won’t derail ketosis.

For those needing more calories, add an avocado (£1.80) or packet of almonds (£1.50). Pret’s nutrition labels show exact weights, making tracking keto macros simpler than at many high-street chains.

What this means in practice

During London’s damp autumn months, Pret’s hot options become appealing. The Chicken Katsu Curry (£5.95) appears risky but contains only 12.3g net carbs if you eat just the chicken and sauce, leaving the rice. Similarly, the Mexican Chicken Soup (£3.95) provides 8.4g net carbs per serving—manageable if other meals that day are very low carb.

Tesco sells comparable ready meals like the Chicken & Bacon Caesar Salad (£3.50) with 5g net carbs, but Pret’s city-centre locations offer convenience when time is short. Budget £10-15 daily for two Pret keto meals plus snacks—comparable to meal-prepping costs when factoring in ingredients and time.

Frequently asked questions

Can I eat Pret’s salads every day on keto?

Rotate between 3-4 lowest-carb options to avoid nutrient deficiencies. No single Pret meal provides all essential vitamins. Supplement with home-cooked meals featuring leafy greens and varied protein sources.

Are Pret’s soups keto-friendly?

Some contain thickeners like flour or potato starch. Always check net carbs—the Tomato & Basil has 14.3g per serving, while the Chicken & Vegetable comes in at 9.1g. On colder days, these may fit if other meals are extremely low carb.

Does Pret offer keto desserts?

Not reliably. Their dark chocolate pots contain 18-22g net carbs. Better to bring your own keto chocolate alternatives or enjoy a cheese snack instead.

The bottom line

Pret a Manger provides viable keto options when you prioritise protein pots, undressed salads, and unsweetened hot drinks. With attention to portion sizes and add-ons, you can maintain ketosis while using Pret for 1-2 daily meals. If you’d rather not do the macro maths yourself, the Keto Dieting app does it for you on Google Play and the App Store.
