He spent a lot of time discussing why humans were not meant to eat meat. The canine teeth, bunny example was pretty silly, if you ask me. I wasn't sold. I'll stick with Sarah Hallberg's advice.


Yeah, lol at the bunny teeth. Humans don't need to rip out an animal's throat with their teeth, or use their teeth to pull off skin etc. There is more than one way to skin a cat. Flat teeth are as useful for mashing up nuts and making them more digestible as they are for grains.

Comparing a polar bear and a panda, the polar bear has the longer digestive tract of a herbivore and the panda has a shorter, more "carnivorous" digestive tract. The panda makes up for this by passing impressive amounts of bamboo through its system so that it can get enough of the easier to digest nutrients to get by.

There's a grain of truth, a higher carb/lower fat diet does result in higher insulin sensitivity than a mixed diet. I wouldn't discourage somebody who's tried it and has success on it, though I might suggest that some supplementation makes sense, and point out that lean protein really doesn't have the same effect vs. insulin sensitivity that a mixed fat and carbohydrate diet does.

Also there's the question of how typical the results are, Barnard talks about people whose diabetes is reversed, his studies paint a milder picture on average, though there are likely to be some hyper responders in there. And even if low fat were better than low carb, (it's not) if people were more likely to adhere to low carb that could still make it the better approach.

Abstract
BACKGROUND:
Low-fat vegetarian and vegan diets are associated with weight loss, increased insulin sensitivity, and improved cardiovascular health.

OBJECTIVE:
We compared the effects of a low-fat vegan diet and conventional diabetes diet recommendations on glycemia, weight, and plasma lipids.

DESIGN:
Free-living individuals with type 2 diabetes were randomly assigned to a low-fat vegan diet (n = 49) or a diet following 2003 American Diabetes Association guidelines (conventional, n = 50) for 74 wk. Glycated hemoglobin (Hb A(1c)) and plasma lipids were assessed at weeks 0, 11, 22, 35, 48, 61, and 74. Weight was measured at weeks 0, 22, and 74.

RESULTS:
Weight loss was significant within each diet group but not significantly different between groups (-4.4 kg in the vegan group and -3.0 kg in the conventional diet group, P = 0.25) and related significantly to Hb A(1c) changes (r = 0.50, P = 0.001). Hb A(1c) changes from baseline to 74 wk or last available values were -0.34 and -0.14 for vegan and conventional diets, respectively (P = 0.43). Hb A(1c) changes from baseline to last available value or last value before any medication adjustment were -0.40 and 0.01 for vegan and conventional diets, respectively (P = 0.03). In analyses before alterations in lipid-lowering medications, total cholesterol decreased by 20.4 and 6.8 mg/dL in the vegan and conventional diet groups, respectively (P = 0.01); LDL cholesterol decreased by 13.5 and 3.4 mg/dL in the vegan and conventional groups, respectively (P = 0.03).

CONCLUSIONS:
Both diets were associated with sustained reductions in weight and plasma lipid concentrations. In an analysis controlling for medication changes, a low-fat vegan diet appeared to improve glycemia and plasma lipids more than did conventional diabetes diet recommendations. Whether the observed differences provide clinical benefit for the macro- or microvascular complications of diabetes remains to be established.
