A good weight-loss diet plan is not a one-size-fits-all sheet from the internet; it is calculated around your height, weight, goal and daily life. Below is a sample 7-day plan and, more importantly, how to get one built for you for free.
What makes a diet plan actually work?
Every plan that works, whatever its name, does one thing: it puts you in a calorie deficit you can keep up. The best plan is not the strictest one, it is the one you can stick to without extreme hunger. Everything below is built on that idea.
Step 1: set your calories
Your daily need depends on your age, sex, height, weight and activity level. To lose weight you stay slightly below that number. A moderate deficit (about 15-25% below your daily burn) usually means a healthy 0.3-0.7 kg per week. Going far lower is not "faster and better" - it costs you muscle and rebounds.
Step 2: a sample 7-day structure
| Meal | Base (swap the exact dish each day) |
|---|---|
| Breakfast | Protein (eggs/yoghurt) + one wholegrain portion + fruit or veg |
| Snack | A piece of fruit + a few nuts |
| Lunch | Lean protein + large salad + a portion of rice/legumes |
| Snack | Plain yoghurt or a small fruit |
| Dinner | Vegetables or soup + light protein (fish/chicken) |
Across the week you change the exact dish - chicken one day, fish the next - while keeping the same balance. That variety is what stops you quitting on day four.
A sample day (around 1500 kcal)
- Breakfast: 2 eggs, a slice of wholegrain bread, cheese, olives, tomato.
- Snack: 1 fruit + a few almonds.
- Lunch: grilled chicken, big salad, a portion of bulgur or rice, yoghurt.
- Snack: plain yoghurt or a small fruit.
- Dinner: baked vegetables, lentil soup, a small wholegrain portion.
The 5 most common mistakes
- Cutting calories too hard. Under-eating slows your metabolism and burns muscle.
- Drinking your calories. Juice, sugary coffee and alcohol quietly undo the deficit.
- Skipping meals. Being starving by evening leads to overeating.
- Weighing yourself daily. Water shifts the scale; watch the weekly average.
- An all-or-nothing mindset. One treat does not ruin a plan; carry on at the next meal.

Frequently asked questions
Is the diet plan free?
The body analysis and your calorie/ideal-weight calculation are free. The day-by-day personalised list is part of a package, so it becomes a programme that updates and is followed, not just a sheet.
Isn't a generic online plan enough?
It gives a rough idea, but two people at the same weight can need very different calories. A proper plan looks at your whole profile.
How often should the plan change?
As your weight drops, your calorie need drops too, so the plan should be recalculated as you progress.
