Protein:
Set high (about 2.2 g/kg body weight) to preserve muscles, promote satiety, and increase energy expenditure through thermogenesis.
Your path to sustainable fat loss
with the rocka calorie calculator
Welcome to your evaluation!
You have chosen the goal "Lose Weight" in the calorie calculator, taking the first important step towards an effective and controlled transformation of your body. Based on your information, the calculator has determined your individual calorie needs and an optimized macronutrient distribution.
To help you get the most out of your results, this guide includes:
A calorie deficit occurs when you consume fewer calories than your body burns. The calorie calculator has calculated a daily calorie amount for you that already includes a moderate deficit of about 15–20%. This ensures:
Set high (about 2.2 g/kg body weight) to preserve muscles, promote satiety, and increase energy expenditure through thermogenesis.
Balanced according to your individual data so that your body primarily uses fat reserves while you remain capable of performing.
Focus on foods with high water and fiber content. Options like vegetables, legumes, psyllium husks, or low-fat quark with flavor powder and the prebiotic fiber inulin provide a lasting feeling of fullness – helping you reach your calorie goal more easily.
Plan your meals in advance – this helps you stay on track and reduces spontaneous purchases or high-calorie alternatives.
Start every meal with a large glass of water. An additional 1.5 L daily can increase your calorie burn by up to 100 kcal.
Plan your meals in advance – this helps you stay on track and reduces spontaneous purchases or high-calorie alternatives.
Increase your NEAT ("Non-Exercise Activity Thermogenesis"), meaning everyday movement: standing instead of sitting, stairs instead of the elevator, walking instead of taking the bus – every bit counts!
Protein has a high Thermic Effect of Food (TEF): about 20–30% of the calories consumed are burned directly during digestion. More protein automatically means more calorie consumption.
Muscles are metabolically active tissue. Just 2 kg more muscle mass increases your calorie consumption – even at rest – by up to 180 kcal per week, which corresponds to an energy equivalent of 1.2 kg of body fat per year.
Use apps or a food diary for guidance – not for self-criticism. Measure your progress in weeks, not days. It is completely normal for your body weight to fluctuate throughout the day.
You don't have to be perfect. Stick to 80–90% of your goals – small exceptions are okay. Consistency beats perfection!
Intermittent fasting, for example fasting for 16 hours and eating for 8 hours, helps limit your calorie intake more easily by shortening the eating window – especially helpful for those with a clearly structured daily routine.
