I'm not claiming that humans were on meat and fat
only diets, but that that was the biggest part of their diet. I honestly don't think that this is even contested by anybody anymore. Humans were apex predators and facultative carnivore for two million years, during which period our physiology was largely formed.
Humans were predators of large prey. In carnivores, predation on large prey is exclusively associated with hypercarnivory, i.e., consuming over 70% of the diet from animals. Source:

When you compare for example 1 kg of cabbage to 100 grams of steak, it may seem that the cabbage plays a very big role in your meal, but they both account for roughly 250 kcals (it is just a silly energy-to-energy comparison, I'm not even considering the essential proteins and fats...). Now, eat 1 kg of cabbage and see how it feels like, and then do the same for 100 grams of steak.
