But anyway, I thought fish + salad = protein + carbs?...
And I looked at a yoghurt bottle and it was like 4 protein, 5 carbs and 3 fats... so more carbs than fats... wtf?

= just for fun.
salad = minimum carbs. You can't just eat row chicken or tuna , put it in a bowl of lettuce or iceberg or whatever green veggies with some olive oil/mustard/lemon and you have a delicious salad. Check out the nutritional facts of lettuce and then weigh how much you can eat in a salad and you will know what i mean, carbs are too little.
Full yoghurt is more fat & less protein , go for low fat yoghurt , 2% , most of them will have ~8gr protein for every 100g. Personally i buy them in 1kg packs , eat about 300g every time. Dont go for 0% , that 2% is usefull, there is some shit going on like fat-soluble proteins in dairy products , long story short = you need some fat in dairy products or else youre ruining them.
Bottom line , don't freak with carbs. When we talk about carbs we mean to avoid pizza , pasta , rice , bread etc... Those foods have like 65g carbs per 100g and you can easily consume 200-300g of them! Carbs that come from veggies , milk , youghurt , meat etc are not worth mentioning , they're too little!
