They can both be healthy, but why are high fat dieters like Mark Sisson and Robb Wolf telling people that carbs make you gain weight? It’s not true. Carbs don’t make you fat. But lots of people also eat high fat diets and lose weight. The high carb vegan doctors will tell you that the fat you eat is the fat you wear, but is that true? Not always. It’s not like every single morsel of fat you eat will become body fat, some will be used to build hormones or used as fuel. Fat is easier to turn into body fat than carbs for sure though. No matter what style of diet you have, you can do it plant based and be healthy that’s for sure.
