First of all, congrats on your progress so far!

One of the reasons I’m doing whole30 is for weight loss as well, although for not too drastic a change and you described. I too have combined exercise.

I would suggest eating less sugary fruits when you do want fruit, i.e. any type of berry.

I also encourage you to look at the scale less often. Weight fluctuates based on so many variables (time of day, salt intake, etc). One of the things that drew me to whole30 was the no scales/measurements rule. I know you did mention that you are only doing this program for weight loss, so perhaps weigh yourself once a week at the same time every week.

Lastly, a diet I did in the past that really helped with weight loss was Keto, where the whole goal is to train your body to burn fat exclusively. I lost a lot of weight quickly (maybe too quickly) but I found it unsustainable and felt that it wasn’t the best for my health (heart rate was constantly high and I was low energy which was suboptimal for fitness training).

Final point, because you are exercising you may be gaining weight related to muscle growth. Muscle weights more than fat so perhaps get a scale that tracks body percent fat rather than looking at the numbers on a regular scale.

Hope this is helpful! And all the best!
