Hello, so I read that Jupiter causes extreme weight gain in the first house... and that my child may grow to be obese? Is this true? She is a Virgo ascendant with Jupiter in the first house (libra). Please let me know if this is true.. I also heard she will he athletic so I hope that evens out if she does end up being on the bigger side. The most important thing to me is that she is healthy.
She is going to be intelligent and philosophical. Likely will have some religious education in her formative years or religion will somehow be involved early on. Not always, but its common.
With regard to weight Mercury ruling the rising sign usually doesn't give obesity. She might be tall however both mercury + jupiter are known for being taller than average. Where mercury is placed in the chart, by sign and house will be more telling of body type. If saturn is with mercury for instance - usually the native will be short - or petite.
Pisces risings are more likely to be obese than jupiter in the 1st. If she does have weight issues it will likely be while young. And will even out with age.
