In a world filled with quick weight-loss promises, restrictive diets, and "miracle" solutions, it's easy to forget that the human body follows biological laws, not trends. Healthy weight loss isn't about punishment or rushing; it's about restoring metabolic balance and your relationship with food.
This plan follows the vision of helping the body return to its natural point of well-being, without extreme deprivation or sacrificing quality of life. The goal is a gradual transformation, focusing on consistency, satiety and preserving lean mass.

1️⃣ Set your time and goal realistically

Let's use an 80kg person as an example.

Goal: Reduce body weight from 80 kg to 70 kg in 4 months (approximately 19 weeks).

Plan strategy:

• 15 weeks in a calorie deficit (weight loss phase - eating less than you burn).
• 4 weeks of calorie maintenance (one per month - eating enough to maintain weight).

→ These monthly breaks help your body and mind rest, reducing the risk of plateaus and binge eating.

Ideal rate of weight loss:

• Between 0,4% and 0,8% of body weight/week.
• For 80 kg, this means losing 0,3 kg to 0,6 kg/week.

→ To reach the 10 kg goal, you will need to lose an average of 0,6 kg/week in the 15 weeks of deficit.

Note: Long and restrictive diets (> 6 months) are not sustainable and can cause loss of lean mass.

2️⃣ Find out your maintenance calories

Before starting a calorie deficit, it's essential to know how many calories keep your weight stable.

Practical calculation method:

→ Record your food intake (everything you consume) and weigh yourself daily for 14 days.

→ Calculate the average weight of the 1st and 2nd week.

Compare: Compare:

• If your weight has varied by ±0,2%, you are at caloric maintenance.
• If you gained >0,2%, reduce 300 kcal/day and repeat the process.
• If you lost >0,2%, add 300 kcal/day until you stabilize.

Practical example:

→ After this process, the weight remained stable with an average of 2.700 kcal/day.
→ This value represents maintenance calorie expenditure - influenced by age, lean mass, routine and training.

3️⃣ Calculate your calories for weight loss

To lose weight, you need to create a controlled calorie deficit (consume fewer calories than your body uses).

General rule:

• Deficit of 500 kcal/day → loss of 0,5 kg/week.
• To achieve 0,6 kg/week, the ideal deficit is 650 kcal/day.

Practical calculation:

• Maintenance: 2.700 kcal
• Deficit: 650 kcal
• Daily goal: 2.050 kcal/day

→ This value ensures consistent loss without a sharp drop in energy.
→ For most people, deficits between 400 and 600 kcal are ideal and sustainable.

4️⃣ Adjust your protein intake

Protein is essential for preserving muscle, controlling appetite and keeping your metabolism active.

• Recommendation: 1,6 g of protein per kg of body weight.

Calculation:

• Current weight: 80 kg
• 80 × 1,6 = 128 g protein/day
• Each gram of protein = 4 kcal (128 gx 4 kcal) → 512 kcal from protein.

→ This intake represents about 25% of the total calories in the diet.

5️⃣ Efficient workouts

Training should continue to stimulate the body to preserve muscle and burn fat.

Strategy:

• 3 full body workouts per week.
• Focus on compound exercises: squats, bench presses, rows, weightlifting, overhead presses, and sit-ups.

→ Avoid increasing the volume excessively and prioritize consistency and intensity.

Note: The body needs to receive the signal that muscle mass is needed, even in a calorie deficit.

6️⃣ Sleep and daily movement

I'm:

Sleeping 7 to 8 hours a night is essential.

→ Adequate sleep regulates appetite hormones (leptin and ghrelin) and improves emotional control.

Daily steps:

Initial goal: 7.000 steps/day.

→ This can represent around 250–300 additional kcal of daily expenditure.

Note: Walking is one of the most accessible and effective ways to increase your calorie deficit without overloading your workout.

7️⃣ Monitor your progress

Consistency must be accompanied by constant evaluation.

How to follow: 

• Weigh yourself daily and calculate your weekly average.
• Compare with the average of the previous week.

Measure:

• Waist and hips (once a week).
• Monthly photos (front, side and back) to visualize body recomposition.

Remember if: Avoid judging progress based on daily variations (fluid retention is normal).

8️⃣ Breaking plateaus (when the weight stops falling)

When your weight stabilizes for more than two weeks, your body has adjusted its calorie expenditure. At this point, it's time to refine your strategy, not radicalize.

Step 1: Reduce 5% of calories from carbohydrates and fats.

Example:

• Total calories: 2.050 kcal
• Protein: 128 g = 512 kcal
• Remaining (carbs + fats): 1.538 kcal
• 1.538 × 0.95 = 1.461 kcal
• Adjusted total: 1.461 + 512 = 1.973 kcal/day

Step 2: Increase your daily steps by 5%.

• 7.000 → 7.350 steps/day.

→ If your weight remains stable after 2 weeks, repeat the process.
Note: These gradual adjustments prevent loss of lean mass and maintain adherence to the diet.
