How to Make a Hotel Breakfast Healthier
At Premier Inn, Travelodge, or Holiday Inn buffets, it is entirely possible to eat a high-protein, sub-400-calorie breakfast:
Hotel Breakfast — Low-Calorie Strategy
- Choose: Grilled tomatoes, mushrooms, baked beans, back bacon, eggs (poached or scrambled)
- Limit: Sausages (high fat), hash browns (deep-fried), pastries (high sugar)
- Skip: Toast and butter, croissants, pain au chocolat
- Result: A plate of grilled full English components without bread or hash browns is approximately 350–400 kcal with 30g+ protein

Costa porridge (regular, no toppings) at approximately 270 calories is the healthiest single-item chain breakfast in the UK. For a higher-protein option, McDonald’s Egg McMuffin at 290 calories with 17g protein is the best calorie-to-protein ratio at any UK fast food chain. The Starbucks egg and spinach protein pot at around 200 calories is the lowest-calorie option but not particularly filling.
Yes — a grilled full English without toast and hash browns is approximately 380–400 calories with 30–35g protein. Choose grilled sausages, back bacon (not fatty streaky), poached or scrambled eggs, baked beans, grilled tomatoes and mushrooms. Skip the toast, butter, and hash browns. See our full English calories guide for the full breakdown per component.
For satiety and calorie control: grilled full English without toast (380 kcal, 35g protein), McDonald’s Egg McMuffin (290 kcal, 17g protein), or two poached eggs on wholegrain toast without butter (280 kcal, 18g protein). High-protein breakfasts keep you fuller for longer than carbohydrate-heavy options like pastries or cereals.
It can be. A Greggs bacon roll without butter is approximately 316 calories with 15g protein — not bad for a quick breakfast. The Greggs sausage roll is around 310 calories. However, Greggs pastry items and bakes are high in saturated fat and sodium. For the healthiest Greggs option, choose the porridge (where available) or the bacon roll without butter over the fried items.
