My parents criticizing my weight loss progress or lack thereof

I lost two lbs in 14 days which I was excited about and decided to share it with my parents who said oh that's it?

Then my dad proceed to say when I try to lose weight, I can lose three lbs in a week.

They're both overweight with health issues like high bp and fatty liver btw and constantly snack on unhealthy foods.

Like not a bit of encouragement and plenty of hypocrisy...

Always find things to criticize me over and give boomer science lectures like hot sauce makes you gain weight or grapes are bad for you or you should drink 8 cups of water a day or "you should lose weight" because I didn't lose 50lb in two weeks.

Like okay fine, I won't share my journey with them anymore but wtf can they not be rude for one second??
