You have stated you have had this issue for some time in previous posts, and you must be super frustrated to still suffer with this.
Can you provide at least 2 weeks of your daily food journal? These diaries should include daily entries of everything you consume, quantities, calories, exercise, water and sleep. Without your diary entries we cannot ever give you accurate or objective feedback
I also found this post from the Aloha to 30BaD's Welcome Wagon!
It speaks how oats may be effecting your acne and your belly.
Are you on any medication, birth control, over the counter supplements?
I used to have the same issues as you explain eating pretty similar to how you do. Until I upped my fruits and lots of lettuce and less and less of cooked food did things start to change for me. You are half my age, but it's a thought. I cant lose weight or have clear skin eating beans, rice, or grains. I practically eat raw vegan now. You should see a dr though to put your mind at ease about your hunch. Keep me posted. I will continue to search around.
I have similar issues that have been assessed by doctors. The acne is probably just unrelated hormonal stuff or an allergy to sunscreen or makeup or soap or anything. I personally don't think you look bloated but if you think you do it could actually be just that you actually have strong abs. Or you need to go to the bathroom. Or from eating beans the previous night. What sort of rice do you eat? I find white rice easier to digest than brown.
then again, I'm not a doctor so don't rely on anything I say. just personal experience.
Any updates? How are you going? I'm having the exact same issues as yourself, being acne which I never had in the past, and bloating only really in my lower belly.
Look at this girls photo though. Her posture is pretty average. Id say chronic lordosis.
