Protein per day

Hi everyone

On 01/10/22, I weighed 109kg, I have been focused on weight loss, I have been on a calorie deficit of 1600 cal per day and 25g protein (I use protein yoghurts because I hate the powder), today I weigh 88kg, so I have successfully lost 20kg, 44lb, which is amazing but I seem to be stuck at this weight, I have been stuck at 88-91kg for 4 weeks now, I have been told to increase my protein intake but how much should I take per day? I work out 2 x a week and swim 2 x a week. My goal is 65kg, how much protein should I be taking to help shift the extra weight? Any advice on how to get past this hurdle of 88kg, I feel like I’m stuck!

Thanks!!!
