Did I eat too little?

Instead of having things such as nutella crepe is better to have a tuna sandwich and you are eating to much carbohydrates for breakfast instead have a proper sandwich for dinner than snacks

Your eating a lot of carbohydrates, sugar, and processed foods. Where's your nutrition? There's little vitamin and nutrients in what you listed. Milk is one of the highest common allergens there is and it creates mucus. Your body is getting no fuel whatsoever.

Looks like a sugar laden low-fat meal plan that would put weight on if it were not so calorie restricted. You are making all the wrong food choices with the wrong methodology if fat loss is your goal.

*Sugar is the dietary villain! Starches are a close second. Eat Smart - Not Less

You need protein!

have some more fruit and veggies along with more protein!
