Adherence

External provision of all food significantly improves adherence to both ketogenic and Mediterranean diets compared to self-provided food, although adherence drops for both when participants must source and prepare their own meals.

If you are trying to follow a specific diet like Keto or Mediterranean, your environment matters more than you think. The study shows that providing all meals for the first month significantly boosts adherence for both diets. When you switch to buying and cooking your own food, adherence drops for everyone, regardless of the diet type. To succeed, consider using meal delivery services or heavy pre-preparation for the first few weeks to build the habit and knowledge, rather than relying on willpower alone to source specific foods from scratch.
