Ok ... I'll tell you about my own experience, but I didn't lose much. I lost 17 kg in about a 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 fruits.

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

Exercise is also important for losing weight.

You can search Pilates videos online and follow them. I've been doing this all the time. It is really useful. I sweat profusely every time I finish. It usually takes more than 30 minutes.

Also, if you can, stand for half an hour after dinner. Because of the holiday, watching TV or something will pass quickly! 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 that you have muscular legs, so do I, but you are still young, so I don't recommend using slimming cream or anything. Well, it would be more helpful to do more leg massage!
