Dr. Gregor, Peak's favorite doctor makes some great points in his latest video. He speaks about angina within 4-5 hours after a high fat meal. This seems on the surface to be indisputable I would be interested in hearing other thoughts on this. I personally have been adopting a low fat plant based diet recently and I'm pretty convinced this may be the way to go.
Well, I don't think anyone disputes that eating a meal with a lot of saturated fat clumps red blood cells and lowers nitric oxide and decreases blood flow. There are a lot of studies out there that show this. Now eating a meal with a bunch of omega-6 oils or a bunch of refined carbs is little better but for different reasons.
Of course, you know I think the lower fat plant diet is the way to go because you can hit or come very close to the HDL, LDL, triglyceride and apoB numbers that you need to control or regress plaque with no real supplemental or medication interventions generally - especially if you add exercise and reasonable sleep levels in. (Poor sleep and a sedentary lifestyle can increase insulin resistance, which helps create a "pattern B" environment, i.e. high triglycerides, small LDL particle size, more LDL particles, etc.)
The other big advantage to a lower fat plant-based diet is increased blood flow due to all the nitric oxide raising aspects of many whole plant foods.
I have a few cautions:
1. Make you have a good omega-6 to omega-3 ratio. There is a big study out there that says that 5 is the highest you want to go on that one. This is why I use flaxseed and sardines. My ratio is probably about 1:1 or 2:1. By the way, Dr. Greger talks about this issue and states clearly that the reason that vegetarians do not better in the studies is the fact that they generally have very poor omega-6 to omega-3 ratios due to processed foods - yes, there are TONS of them at places like Sprouts and Whole Foods - and use polyunsaturated oils, peanut butter, etc.
2. Don't go too low in fat imo. You need some fat to absorb nutrients. My target is the 15-20% range actually. This is the recommendation of the Pritikin Edge. You should be able to meet your lipid targets in this range.
3. Remind me and I'll include my latest diet, which seems to have solid RDA numbers (except for selenium which I take separately).
Good luck if you try it and let me know how it goes.
