Oh I agree 100%. I'm just saying that a lot of people just jump in without really doing the proper research or understanding why they would give up carbs. "Internal health" is something that needs to be monitored as well.
How is IF bro science? Much like low-carb, there have been plenty of scientific studies that talk about the benefits of fasting.
I'm definitely no expert on the matter, but I personally haven't seen any decent studies regarding the fasting aspect of it being the health benefit, and not the fact that the very act of fasting results in a reduction of specific cutbacks that may be responsible for the weight loss/health benefits. And IF is so inconclusive of a term that it almost lacks meaning. The Bro Science aspect of it comes from the sub-genres of the diet (20/4, Lean Gains, etc) which are definitely not studied in a scientific setting, and instead, are little more than personal anecdotal observations by by health/nutrition enthusiasts.
