It's important to note that antibiotics tend to beget themselves. The more antibiotics you take, the less balanced your system becomes, the more susceptible you are to infection, the more antibiotics you need. If the mother's vaginal flora is out of whack then it may be from prior use of antibiotics. Yeast infections are common in women who take antibiotics. So to say that antibiotics help a problem that they likely caused is a bit misleading.
Just to chime in on this. There are actually natural treatments to help people get their body to a healthy state and recover from yeast infections. For one, I think you said it earlier, was to get rid of processed carbs/sugars as they feed on that. Another would be finding someone that is an Internal Health Specialist certified (I have this certification) and getting a product through them called SmI (it's an enzyme product). This is a great way to reduce systemic yeast as well it can be used as a douching agent for the woman to help regain the pH balance and natural flora of the vaginal canal.
Eating less food to lose weight doesn't work in the long-run anyhow, unless you literately "starve yourself to death". Your bodies metabolism will slow down to compensate and why you should do something like physical exercise also with a good low fat balanced diet that's not to high in carbohydrates to help burn off fat.
Low fat diet? That's one of the worst things for you. Fat is only bad if it's transfat, or animal fat in which the animal consumes a high grain diet, is injected with antibiotics, steroids, isn't able to "get out" and roam, etc. Dietary fat is very good for you and much of our problems now days is the stupid suggestions for many people to go on low fat diets. It's the processed carbs that are doing us in. Once the "low fat diet" suggestions came about in the medical community, heart disease shot straight up.
Wild animals can go without food for days. They evolved to go through times of no food. I don't think our ancient ancestors had 3-4 times a day meals either.
We were built to store fat for this very reason. Our "starvation" period was the winters so we would beef up prior to the winter (hence a massive feast for thanksgiving). But now...we are constantly in a thanksgiving mode, thus storing fat all the time...on top of not being active enough.
Dieticians say weight loss is usually:
70% Dietary changes (ie. less calories)
20% Exercise
10% Good genetics.
So if you don't change your eating ... you won't lose weight.
Food actually influences genetics. The current theory out there is that nothing is genetic and it's actually epigenetics (basically things that change the gene - I wish I had a recent research article I just read about this to link here) that do the work. They are markers on the genes that, yes, your parents pass down...but think of it as a yellow book amongst black bound books in a large bookshelf; you are likely to pick out those yellow books but with a proper lifestyle, you don't have to. It's been shown numerous times that raw food influences these epigenetics to turn on ones to combat cancer and reverse diseases...and even some MD's have changed their practices to getting people off their meds, off the junk food, and eating a raw food diet with exercise and have had awesome success with reversing literally anything that walks into their offices.
But anyways, you are correct about diet being the biggest thing for body transformations (although, I don't believe in the calorie restriction as they actually need to compare a calorie restricted raw diet vs a non restricted raw diet - bc let's face it...if you are eating less processed, chemical stuff, sugary, transfat,
substances, then yes, you will likely live longer lol).
