Not a diet: twelve weeks to learn how to eat.

At the first appointment, your coach sets a three-month goal with you: losing weight, gaining it or maintaining it. They enter your details (age, work, sport…) into the Newtrition app.

The app calculates what you need each day, well balanced between proteins, carbohydrates and fats. Your coach then writes the week's menu with you, based on your tastes and habits.

Follow-up lasts 12 weeks. At each appointment you talk through your week and the next menu is adjusted: a plan is much easier to stick to with a weekly appointment than a monthly one.

Each time you leave with your menu, your shopping list and your progress, also sent by email.

The programme adapts to your family and work commitments: a plan you can't follow is bound to fail.

No high-protein diet, no shakes or pills: menus that aren't low-calorie, and long-term re-education of your eating habits.

• Weight loss: a balance that draws on fat mass and preserves lean mass
• Weight gain: putting on good weight, mostly lean mass
• Maintenance: new menus to stabilise your new weight
• Sports nutrition: progressing or preparing for a competition, with weekly weight and body-fat checks
