Every crash diet promises fast results. The problem is not that they do not work, it is that they do not last. A moderate pace of 0.4 to 0.8 kg per week is boring, and it is exactly why it works.
You keep your muscle
Lose weight too fast and a big chunk of it is muscle, not fat. A moderate deficit, paired with enough protein, tells your body to burn fat while holding onto the muscle that keeps you strong and keeps your metabolism up.
You avoid the rebound
Aggressive deficits spike hunger and crater energy, which is why so many end in a binge-and-regain cycle. A gentler deficit is one you can actually live with, and adherence, not intensity, is what predicts results a year later.
The math
A deficit of around 450 kcal a day lands you squarely in that sustainable range. It is enough to see the scale move steadily, without the misery that makes you quit.
Anyone promising much faster is usually selling you a rebound. TailorFork targets this pace by design: a real deficit built from meals you enjoy.
