The first step is to not give a damn about your health. After that, eat whatever the hell bạn want with no restraint. If bạn haven't experienced severe pains in your stomach after two weeks, bạn know it's a an toàn, két an toàn diet. If bạn have, bạn can ask this câu hỏi to a medical expert, since you'll need to see one then anyway.
I'm not too sure. My sister, she has a pretty high metabolism that no matter what she eats she seems to never put on the weight. But when I lived with her she wasn't always eating, mostly at meal times and if she wanted a snack. Either way I don't really have the answer. bạn could ask a doctor, they may have a better answer for you.. But be careful when it comes to salty foods, as bạn đã đưa ý kiến bạn crave, if bạn have too much salt it could cause damage to your kidneys, not to scare bạn though.
