While I will give you some extra tips you need to care for if you want to really be involved in this experiment and stay healthy and lose some weight 

First, you need a kitchen scale; eating without controlling your portions will never get you the results you want. Also, controlling portions makes food more delicious, and believe me when I say that.

To start, don't cook more than your portion. Cooking a lot means you will eat a lot, so at the start you need to train yourself and your body that this is what it will get, and there is no more food waiting on the stove.

Learn to cook healthy: you don't need to fry food when you can air-fry or cook in the oven. 

You are allowed to eat junk food on the weekend as long as it matches the week's plan, so why not try some vegan snacks during vegan week? 

learn to read labels, understand calories, and look for lower-calorie, healthier options.

Be creative, learn new recipes, and don't repeat yourself; the excitement of trying new flavors can make you forget the limitation. 

prepare a shopping list every Saturday night and go shopping on Sunday for your new week; it is unbelievable the feeling you get when you see eggs or milk after a week without them.

when you are out, try to stick to your weekly plan if you can; if it breaks, it's okay, continue the next day 

You know a healthy lifestyle includes cutting back on sugar, or at least decreasing it, and using healthier options like honey.

Make time for at least 20 minutes of exercise at least 3 days a week.

Teach your body to stop eating after dinner; intermittent fasting is very helpful for weight loss in people with a slow metabolism.

Spices are your real friends; don't be scared to use them and try them; however, salt can be an enemy, so don't overdo it. 

Always remember, there is no magical diet or eating style that can make you healthy without giving some effort. This lifestyle aims to make losing weight more fun, while looking forward to a new week to come with new shopping lists and recipes… 😊
