170x4=680, so only around a third of your cals are coming from carbs. 2300 cals a day isn’t much, and 170g of carbs is nothing. Why are you afraid of carbs? Are you cutting?
Whats wrong with carbs anyway, if your eating 2300 calories a day chances are you dont have much muscle and could use the extra calories/carbs.
If weight loss is the issue, I would wait as long as I could without cutting carbs. No diet sucks worse than a low carb diet, no energy, loss of strength, it just blows.
if you are cutting down with this many carbs and you have plateaued(if you havent then continue), then cut out bread definitely. i say eat veggies, 1-3 fruits(at breakfast and post workout shake), and some whole wheat rice in post workout meal and a bit before training on training days(for example 30grams of it preworkout and ~100 post workout)
in the end you’ll end up with around 200 grams of carsb in workout days and around 50-100 in non workout days.
you’ll also need cheat meals to keep metabolism up. if your metabolism goes down and you plateau even with the above there is no way you gonna lose any more fat, except with supplements or something…
