Well ... I'll give you my own experience, but I didn't lose much. I lost 17 kg in about one month, but I think it's enough for you.

My recipe is

Breakfast: a banana, oat milk, skim yogurt, sugar-free soybean milk (choose one)

Lunch: salmon sashimi, a cup of soybean milk or milk, and some fruit.

I basically don't eat dinner, but I usually eat some fruit.

Exercise is also very important for losing weight.

You can search the Pilates video online and follow it. I've been doing it all the time. It's really useful. Every time I finish it, I sweat profusely. It usually takes more than 30 minutes.

Also, if you can, stand for half an hour after dinner, because you have a holiday, so watching TV or something will soon pass! Be sure to stick to it!

I used to be lazy, too ...

But persistence is victory.

I hope you succeed!

By the way, you said you have muscular legs, so do I, but you are young, so I don't recommend you to use slimming cream or something. Well, it will be more helpful to do more massage on your legs!
