A high protein low calorie meal plan is the gold standard approach for losing fat while preserving — or even building — lean muscle mass. By keeping calories in a deficit while eating 140–170 g of protein per day, you force your body to burn fat for energy rather than breaking down muscle. This 7-day UK plan delivers 150+ g of protein daily from lean, widely available sources such as chicken breast, tinned tuna, eggs, Greek yogurt, and cottage cheese — all affordable and easy to find in any major UK supermarket.

Protein has the highest thermic effect of any macronutrient — your body burns roughly 25–30% of protein calories just by digesting it. It is also the most satiating macronutrient, meaning gram for gram it keeps you fuller than carbohydrate or fat. Research from the British Journal of Nutrition shows that increasing protein to 25–30% of total calories significantly reduces appetite and late-night snacking. This plan targets approximately 1.8–2.2 g of protein per kg of body weight — at the high end of the recommended range for people losing weight while exercising.
Below is a sample week. Each day is planned to hit approximately 1,550 calories with a strong protein focus. Calorie and protein figures are estimates — weigh ingredients if you need precision. Use the free generator to get a freshly personalised version.

Tips for Success
Spread protein intake across all meals rather than concentrating it at dinner. Your body can only synthesise around 30–40 g of protein per meal effectively.
Tinned tuna, boiled eggs, and low-fat cottage cheese are your best friends — all extremely high in protein, low in calories, and require almost no preparation.
Use protein powder strategically, not as a meal replacement, but as an easy top-up to bring a meal's protein content up to 30 g+.
Combine protein sources where possible — e.g. chicken with lentils, or eggs with Greek yogurt — for a full amino acid profile.
Track protein, not just calories. Hitting your protein target is more important than tracking every macronutrient on this plan.

Frequently Asked Questions
How much protein do I need per day to lose fat without losing muscle?
Most research suggests 1.6–2.2 g of protein per kg of body weight. For an 80 kg person, that is 128–176 g per day. This plan targets the higher end to maximise muscle preservation.
Is high protein safe for kidneys?
For healthy adults with no pre-existing kidney conditions, high protein diets are considered safe. If you have kidney disease, consult your GP before increasing protein intake.
Can I follow this plan if I do not eat meat?
Yes, though it requires more planning. High-protein vegetarian sources include eggs, Greek yogurt, cottage cheese, tofu, edamame, and protein powder. See our vegetarian plan for more ideas.
