Unfortunately, losing weight in and of itself has not been terribly predictive of whose sways succeed. Losing weight is not the end game, it is the type of diet you follow that appears to make the most difference. For reasons we don't understand, animal studies have found that a diet higher in carbs (not sky high but just higher), somewhat lower in fat and protein, with a higher % vegetable based fats, not animal based fats, sways pink.

So it's not going to be your best bet to do keto or any very low carb diet. Some people actually can still get girls this way because it will still be a more restrictive diet (as we like to say, protein + carbs makes boys, and I do not suggest any blue swayer follow a keto or VLC diet because it may sway pink) but it will simply not be as reliable as LE Diet is.

I do everything in my power to prevent people from losing their periods due to excess weight loss.

No, I do not recommend having hubby's sperm tested. to the best of scientific knowledge, men make 50-50 X and Y sperm. They HAVE to because that is how sperm are formed - XY sperm split in the testicles to become half X and half Y sperm. More about that here: https://www.genderdreaming.com/forum...x-y-sperm.html It's been extensively tested and while there are some old studies that claimed to find a difference, they used a method of sorting sperm that was later found to be inaccurate. There are disreputable companies who take people's money to do this but it's about 50-50 each time. (It obviously cannot be EXACTLY 50-50 for the same reason that if you took a scoop of mixed yellow and green split peas you would not get exactly 50-50, and sometimes people claim this proves something, but it really doesn't and studies using accurate sperm testing methods have found that men make about 50-50 X and Y sperm no matter what.)
