An 1,800 calorie meal plan is one of the most widely recommended targets for sustainable weight loss in the UK. It is particularly effective for women who are moderately to very active, and for men who are sedentary or lightly active. Eating 1,800 calories per day typically creates a 300–600 calorie deficit — enough to lose 0.3–0.6 kg of fat per week without the energy crashes associated with more aggressive cuts. This plan is built around familiar UK supermarket ingredients to keep both the cooking and the shopping straightforward.
At 1,800 calories, you have enough room to eat satisfying, varied meals — three proper meals a day with room for a snack. This makes the plan far more sustainable than 1,200 or 1,500 calorie approaches. The meals in this plan are built around a protein target of 100–130 g per day, with the remaining calories split between complex carbohydrates and healthy fats. High protein keeps hunger at bay, while the carb allowance gives you enough energy for exercise and daily life.
