Why most diets fail
The statistic is depressing: 80% of people regain the weight they lose within two years. The reason is simple - they used a method they could not sustain. Crash diets, shake plans and meal-replacement programmes work brilliantly for 6 weeks and fail brilliantly for the next 6 months.
The sustainable rate
Aim for 0.5 to 1 kg per week. This rate preserves muscle, keeps your metabolism intact and produces habits that last. Anything faster is mostly water and muscle, and it always returns.
The 90/10 rule
Eat well 90% of the time and live freely 10%. That is roughly 3 meals a week where you eat whatever you want. This is not a cheat day - it is a sanity meal. Restrictive diets fail because they remove this margin.
Build identity, not willpower
People who say "I am someone who eats well" succeed far more often than those who say "I am trying to eat well". Identity drives behaviour. Speak about yourself as a healthy person and your habits follow.
Movement you enjoy
The best exercise is the one you actually do. If you hate the gym, walk. If you hate running, dance. If you hate dancing, lift weights. Find the form that you would pay to do and do that.

- 0.5 to 1 kg per week is the sustainable sweet spot
- 90/10 eating beats 100/0 perfection
- Identity-based change outlasts willpower-based change
