Well, his body is using carbs for energy, yours is using fat now.A buddy of mine (Keto skeptic, carb enthusiast for working out) says his nutritionist put him on 240g of carb a day (he does work out a ton) and less than 55g of fat per day.
I was shocked because I eat more fat than that and he works out 100x more than I do.
A lot of "nutritionists" especially gym nutrionists, aren't digging deep into science, they're just continuing traditional recommendations.
Low fat diets are a difficult way to lose weight, and are much more likely to leave you deficient in important nutrients, but they've been the standard recommendation for 70 years.
