You think 100g of carbs a day is decadent? Why do you think carbs are bad?
Grains are generally unhealthy. I think we can all agree with that statement. However, just because wheat is bad for you and wheat is a carbohydrate doesn't make carbohydrates evil. How would you feel if I said because canola and soybean oil are bad for you than fats are bad for you? I think A LOT of people would have a problem with that statement, right? So why associate the same logic with carbs?
Historically, the oldest humans lived in regions along the equator. It was warmer. Food was more plentiful. And food grew all year long. There were always copious amounts of fruits and vegetables to fall back on when the hunt went bad. Some days, they may not have even gone hunting if they didn't feel like it. If Grok found a giant bunch of bananas, he would not discriminate. He would eat hundreds of grams of carbohydrate until he fell asleep, and he'd be thrilled to do it again. This isn't unnatural. What's unnatural is sugar and grains as they all require lots of processing just to be edible on a basic level.
There were no "macronutrient" ratios. Just apply logic to it. Grok didn't have a fridge, so he couldn't store lots of food to have a four course meal. He probably ate one thing - either they killed an animal and ate all meat or the hunt failed and ate all fruits or tubers. Magically, we get the fattest when we combine carbohydrate AND fat in a single sitting - our body burns the carbs and stores the dietary fat. My guess is this is because we probably rarely combined carbs and fat in meals historically - it was one or the other. So yes, you can have some days where you enjoy copious amounts of carbohydrate. That is natural. Just keep fats very low on those days. I regularly have days where I eclipse 300g of carbohydrate, but I just make sure to keep fats under 40g on those days (usually in the 20-30g range). My go-to meal post-workout is 99% lean ground turkey (2g fat/pound) and two pounds of sweet potatoes cut into fries and baked (no fat added). It's helped me cut a good bit of body fat eating like this.
Also, figure your biological history into things. If you're white, you probably come from a colder climate than someone who is black. A black person would ancestrally be from a warmer climate, meaning they probably evolved eating more carbohydrate than a white person, who for many months of the year had to survive only on animal products as it was too cold for plants to grow. It's my opinion that black people would perform better on a higher carbohydrate diet than white people. It's probably no coincidence that white people carry extra weight much more poorly than black people and seem to balloon up more easily on the high carbohydrate SAD. Just some observations I've made.
