According to the NHS calorie guidelines: The NHS recommends an average of 2,000 calories per day for women and 2,500 for men, though this varies based on your size and activity level.
Why Protein Is the Hardest Macro to Hit on a Budget
Protein is a macronutrient essential for muscle maintenance, immune function, and overall health, especially for adults over 40 whose needs increase due to natural muscle loss. The NHS recommends a minimum intake of 0.75 grams per kilogram of body weight daily, with increased needs for older adults [NHS protein intake recommendations]. Protein sources tend to be more expensive per calorie than carbohydrates or fats, making budget adherence difficult. Meat, dairy, and fish prices fluctuate, and many high-protein plant-based foods require larger quantities to meet equivalent protein amounts. The cost per gram of protein can be double or more compared to carbs, highlighting why protein is the hardest macro to consistently meet without overspending in the UK.
The Cheapest High-Protein Foods in UK Supermarkets Right Now
The cheapest high-protein foods available in UK supermarkets include canned tuna, eggs, dried lentils, frozen chicken thighs, and natural yoghurt. According to Money Saving Expert's cheap food guide, dried lentils cost as little as 20p per 100g providing 9g of protein, while frozen chicken thighs average £2.50 per kg with 24g protein per 100g [Money Saving Expert cheap food guide]. Eggs are around 10p each and pack 6g protein. Bulk canned tuna in brine provides 25g protein per 100g and costs about £1.10 per tin. To optimise budget and variety, buy these staples in bulk from supermarkets such as Aldi or Lidl, which consistently offer the best prices for protein sources in the UK. Cooking lentils once can generate multiple meals like dhal, salads, or patties, while chicken thighs can be roasted, shredded, or curried to diversify meals.

How to Structure Your Meals Around Budget Protein Sources
The three common mistakes that reduce meal prep variety and nutrition on a budget are: 1) relying on a single protein source daily, causing monotony and nutrient gaps; 2) neglecting to repurpose cooked proteins into new dishes, resulting in food waste; 3) overemphasising carbohydrates which fill but don’t support muscle maintenance. These lead to poor adherence and missed protein targets. Structuring meals should begin with choosing 2-3 affordable protein bases per week—such as chicken thighs, eggs, and lentils—then planning 3-4 different meals per protein. For example, roast chicken can become sandwiches, salads, or pasta toppings. Lentils can appear as soup, curry, or burgers. This approach ensures variety, cost control, and meets the 1.0–1.2 grams/kg protein target recommended for adults over 40 [British Nutrition Foundation protein and health].
Common Mistakes When Eating High-Protein on a Budget
Contrary to popular belief, consuming expensive protein supplements or premium cuts is not necessary to meet protein goals efficiently. One common mistake is prioritising convenience over cost, leading to reliance on pre-packaged meals or protein bars that cost £2–£3 per serving versus whole foods costing under £1. Another error is ignoring plant-based proteins, which can be more cost-effective and versatile; dried beans and lentils provide 20–25p per 100g and offer 9–10g protein [Money Saving Expert cheap food guide]. Additionally, failing to diversify cooking methods reduces appeal and increases food waste. The British Nutrition Foundation highlights that combining animal and plant proteins can meet nutritional needs while reducing grocery bills [British Nutrition Foundation protein and health].

Your High-Protein Budget Meal Plan for the Week
Start your week by purchasing budget-friendly proteins: 1kg frozen chicken thighs, 500g dried lentils, a dozen eggs, and natural yoghurt. On day one, roast chicken thighs seasoned with herbs for dinner; use leftovers shredded for salads and wraps on days two and three. Cook a large batch of lentil dhal to serve with rice, and turn leftovers into lentil patties for lunches. Incorporate boiled eggs as snacks or added to salads. Rotate natural yoghurt with fresh berries for breakfasts. Prepare all proteins on Sunday to save time. This meal plan meets the NHS’s protein recommendations for adults over 40 and manages costs effectively.
