Not medical advice
The plans and information from Afvallen & Afblijven are intended as general lifestyle advice for healthy adults. They are not medical advice, a diagnosis or a treatment, and do not replace a consultation with a doctor, dietitian, physiotherapist or other healthcare provider.
Always consult your GP first if you have a medical condition (such as diabetes, cardiovascular disease or kidney problems), take medication, are pregnant or breastfeeding, have (or have had) an eating disorder, or are unsure whether losing weight or training is responsible for you. Stop training if you experience pain, dizziness or shortness of breath.
Put together automatically
Our plans are put together automatically by our software, based on your answers, our calculations and our instructions. We automatically check nutrition plans for things such as calories, protein and the number of meals. Even so, a plan may contain imperfections, such as an inaccurate nutritional value or an exercise that suits you less well. Use your common sense, adjust where necessary and get in touch with us if something isn't right; we will then adjust it free of charge.
Your own information and the safety check
Your plan is based on what you fill in in the questionnaire and the check-ins. So answer truthfully and completely, including the questions about your health. The safety check before payment is a simple initial screening based on your answers, not a medical assessment.
Allergies
We take into account the allergies and intolerances you tell us about, and check every nutrition plan for them. So list them all: we can't take into account what you don't tell us. We cannot guarantee that a product is free from an allergen or traces of it. So always check the ingredients and labels yourself, as the composition of products can differ between brands and can change. See also the terms and conditions.
No guaranteed results
With Afvallen & Afblijven, you are buying a personal plan and guidance, not a guaranteed result. We do not promise that you will lose a certain number of kilos, reach your target weight within a certain time or build a certain amount of muscle. How much weight you lose or muscle you build varies from person to person and depends on factors such as your body, your health, your sleep, your circumstances and how closely you follow the plan.
Forecasts on the website and in My plans, such as an expected date for reaching your target weight or the expected progress in a chart, are estimates based on averages and not promises. Examples and charts of fictional customers show how it works, not what you will achieve.
You do have a 14-day satisfaction guarantee on your first payment: if you are not satisfied with the service, you can request your money back in My plans. This guarantee concerns your satisfaction, not any particular result. See article 10 of the terms and conditions.
