# What a realistic weekly loss looks like > 0.5 kg per week sounds modest until you see the math behind it. Why the slower paces win more often, and why the app protects a safe floor. _Sanne de Vries · 29 May 2026 · 5 min read_ Somewhere between the before-and-after photos and the "lose 10 kg in a month" ads, our sense of normal broke. Time to reset it: 0.5 kg per week is not the slow lane. It's already a brisk pace that asks something of you every single day. ## The math behind a pace When you set up MealSnap you pick a pace: 0.25, 0.5 or 0.75 kg per week. Behind those options sits plain arithmetic. Losing about 0.5 kg of body fat in a week takes a daily deficit of roughly 550 kcal. Every day. That's a full meal's worth of food, seven days in a row, week after week. Double the pace and you double the daily gap. Suddenly "just 0.5 kg" sounds different. ## Why smaller deficits stick On paper, a bigger deficit finishes faster. In practice, three things push back: - **Hunger and mood.** A 550 kcal gap is noticeable but livable. Bigger gaps make you tired, cold and cranky, and willpower runs out long before the goal arrives. - **Muscle.** The steeper the deficit, the more of your loss comes from muscle instead of fat, especially without enough protein. Slower loss is better-quality loss. - **Life.** A small deficit leaves room for a birthday, a restaurant, a Friday. A harsh one turns every social event into a conflict, and the plan usually loses that fight. A deficit you can hold for six months beats one you can hold for six days. Every time. ## There's a floor, and it's there on purpose Whatever pace you choose, MealSnap never sets your daily calories below a safe minimum. If your combination of stats and pace would land underneath it, the app adjusts the plan, not your health. Eating far too little doesn't speed things up for long anyway. Mostly it speeds up quitting. ## Slow is not failing At 0.5 kg per week, 6 kg takes around three months. That can feel endless in week two. But here's the quiet truth: the three months pass either way. The only question is whether you're 6 kg lighter at the end of them, with your muscle, your mood and your habits still intact. So pick the pace you can imagine keeping through a bad week, not the one that impresses you on a good day. Watch the weight trend, not the daily number. And when progress feels slow, remember what it actually is: roughly 550 kcal of quiet discipline, every day, adding up exactly the way the math says it will. That's not failing. That's what it's supposed to look like.
