His protein shakes are carb free he does not eat eggs for energy and 10 grams of carb per day is keto by any ones standard.
He has studied nutrition in great depth he knows exactly what is in the foods he eats and the benefits of eating eggs goes way beyond carbohydrate count the boost to testosterone only being one among many.
Many doctors nutritionists and dietitians and quite a few people here could learn a lot from him
he studies it just as he studies his subject at university and he is on track for a first in that.
You do not need carbohydrate for energy that is a myth He has found that out in practice not theory.
We actually had an argument over this the other day I stupidly said where and when did you get your medical degree he countered with doctors know nothing about nutrition and I could not argue with that in the main they don't.
Just so you know he isn't talking out of his posteria.
" Eggs are a fantastic source of protein, cholesterol, vitamin D and omega-3s, all of which aid in the production of testosterone. Eggs are a very versatile ingredients and not only do they help increase testosterone levels, the protein in them helps with muscle building too!"

edit to add Did I say he eats vegetables if I make a low carb meal he does not eat the carby stuff simple as that the carbs in the eggs are the sum total of the carbs he may eat in a day. but he does not eat them necessarily every day just most days.
