Thanks for sharing your experience. From what I've read, soy milk does contain phytoestrogens - specifically isoflavones - but the science doesn't support the idea that they're harmful to men in moderate amounts. These plant compounds can mimic estrogen weakly, but they're much less potent than the hormone your body produces, and research generally shows they don't significantly affect testosterone levels or cause feminizing effects in men.

If cutting soy milk helped you drop 5 kg, that's great - but it may not have been the soy itself. It could be that you removed extra calories, reduced bloating, or changed something else in your diet at the same time. Everyone's body reacts a little differently, and if removing soy worked for you, then that's a valid personal observation. I just want to be sure we're not overstating the effect of phytoestrogens based on anecdote alone.

Here's one solid science-based article from Harvard that breaks this down in more detail: Straight Talk About Soy
