Build me a simple web app called Lela that helps people manage their diet and practice yoga at home.

I want users to be able to create an account, enter basic details like age, height, weight, and activity level, then get a diet plan based on their BMI and estimated calories. The app should help people choose whether they want to lose weight, maintain weight, or gain weight, and then show them a clear daily diet suggestion in a friendly way. It should also have a few extra pages like a home page, a recipes section, a My Diet page, and an About Me page.

If possible, include a yoga posture detection feature so users can practice at home and get feedback on their pose. Keep the design clean and easy to use on a phone or laptop, and make it feel like a helpful smart dietician rather than a medical tool. Look up current docs online if you need to.
