I will be responding with my thoughts next week or two.
Or three or four
After this was first posted, Mark, Goose and I had some great discussions on it and this post is a compilation of our thoughts.
Doug made some great points including (paraphrasing) that humans are not biologically vegans though we may choose to be vegan, that what we are asking people to do is very hard in this environment, to be good to ourselves on the path and to honor our improvements along the way.
I also agree with Doug on the point that tying to maintain a diet below 300- 400 cal/lb can be very difficult due mainly to a lack of calories and satiety.
This is why, when I teach my lecture on calorie density, I recommends aiming for a “Sweet Spot” within the range of 400-800 cal/lb that can be successfully maintained. That is why that area of the graph is coded green. That is also why the Sweet Spot graph is coded yellow and orange for going under 400 cal/lb and for going over 800 cal/lb. The best way to find one’s Sweet Spot within that range is by shifting the ratios of the recommended foods on your plate. (See Sweet Spot graph below)
What I liked about the question from the patient is that it covered virtually everything that we hear about why it is so hard to do this. It reminded me of many emails and conversations I have had with clients, participants, patients, etc over the years all summed into one. It raised many important topics we deal with including the environment, family members, eating out, restaurants, time, socializing, access, triggers, old habits, the food industry, etc.
My concern with the response is that it seemed to focus on whether humans (or our ancestral diet) were biologically vegan or not, and how best to spike the diet to make it more like our ancestral diet. However, even if someone was to adopt the recommendations to spike their diet, or whether they were vegan or not, they would still have all the above mentioned issue to deal with. Therefore, spiking the diet with some tofu or avocado is not the solution nor will it solve all the above issues.
Some points...
- While an interesting comparison, this is not a Stone Age vs “Modern Diet" issue. Why? There was no one Stone Age diet. Its compositions varied depending on location, geography, etc
- The largest increase in obesity, and our largest increase in total calories, was from ~1980 to ~2000. So, therefore why not just compare the diet from 1960 to 1980 (when obesity was fairly rare) to the 1980-2000 diet when obesity soared.. During that time period, calories went up ~20% with 48% of those calories coming from fat, 34% from refined grains, and 10% from added sugar. This is also the time period that the toxic and obesogenic environment emerged (see original post above).
- The meat back then would have been truly free-range, and grass-fed making it much lower in the percent fat and calorie density then stated. I am not sure where the stated 1000 cal/lb came from. It does appear on my calorie density chart which lists animal protein as 1000 cal/lb. However, as I always say when presenting the info, this refers to a modern fatty steak you might get in a restaurant, not free-range grass-fed wild game. I ran the numbers at the USDA Nutrition Database (
https://fdc.nal.usda.gov) and here are some examples....
Wild Game // Calorie Density // %Fat
Elk// 503 //12%
Moose // 463 // 7%
Deer // 717 // 18%
Antelope // 517 // 16%
Bison // 649 // 15%
Rabbit // 517 // 18%
Squirrel //544 // 24%
As you can see the average of these examples of wild game is ~600 cal/lb and ~15% fat. (I also discuss this issue in the Fat Lecture.)
- To prove that the calorie density of the Stone Age diet was 700 cal/lb, they said, if you take the calorie density of the starches/potato (400 cal/lb) and the calorie density of the meat (1000 cal/lb) and add them together (1400 cal/lb) and divide by 2, you get 700 cal/lb. However, this is not how calorie density math is done. When using calorie density, that math would only be correct if they ate the exact same weight of meat and potatoes every day (or on average), which is highly unlikely. A higher contribution of weight from potatoes would lower the overall calorie density and a higher overall contribution of weight from meat would raise the calorie density as seen in these examples (using their numbers).
- If the weight of each was the same…
2 lbs potatoes = 800 calories
2 lbs meat = 2000 calories
4 lbs 2800 calories
2800/4 = 700 cal/lb
- If there was more meat than potatoes….
1 lbs potatoes = 400 calories
3 lbs meat = 3000 calories
4 lbs 3400 calories
3400/4 = 850 cal/lb
- If there was more potatoes than meat…
3 lbs potatoes = 1200 calories
1 lbs meat = 1000 calories
4 lbs 2200 calories
2200/4 = 550 cal/lb
- Once we correct for the average calorie density of grass-fed wild-game and for the way calorie density math is done, the concept of a spike and its benefit, fades away..
- The estimated Calorie Density of pasta, tofu and beans used in the podcast are also inaccurate and there is also more to satiety than the % fat and calorie density. Both of these are clarified here...
https://www.drmcdougallforums.com/viewtopic.php?f=22&t=62161Here are two example of foods that have the same calorie density but different satiety and impact.
Tofu vs Potatoes
https://www.drmcdougallforums.com/viewtopic.php?f=11&t=60912&p=615809&#p615809Avocado vs Garbanzo beans
https://www.drmcdougallforums.com/viewtopic.php?f=11&t=59073&p=594904&#p594904A few more points
- “Wet" starches are not a good description as the actual issue is water rich or high water content starches with intact fiber. For example, dip a cracker in water and you have a wet cracker but not a water rich or high water content cracker. We could say the term "wet" starches is all washed up.
- We currently have several diets out there that are WFPB and allow for (and even recommend) the inclusion of higher calorie dense and/or higher fat plant foods and/or the occasional animal products (ie, McDougall, Ornish, Pritikin, Gould, 7th Day Adventist, E2, Greger). Do they have better long term compliance or success? I know of no research showing they do and they have been around for decades. If anything, it seems the stricter versions of some of these programs (MWL, Ornish Reversal, Esselstyn) have the better results and compliance.
- There are 3 McDougall studies over time, the McDougall 7 Day Program Study and the McDougall 1 year MS study, both of which used the regular McDougall program, and the Broad Study, which used the MWL principles. The Broad study had the best outcomes of the 3 and of any similar type study.
- Adding a spike of tofu or avocado to a diet that has a calorie density of </+ 400 cal/lb will have little impact on its overall calorie density or % fat, regardless if figured per meal, per day or per week.
- If avocados are a great spike food, let's compare them to garbanzo beans.
https://www.drmcdougallforums.com/viewtopic.php?f=11&t=59073&p=594904#p594904It seems to me, if we are going to spike the diet, garbanzo beans would be a much better choice than avocado and almost the true perfect choice.
- I am not a fan of the word “spike” as many of the spike foods are common trigger foods and can be risky for many people. What I am recommending for those who need it, is a “shift" and not a spike. That’s the way I have always taught this. We can “shift" the diet slightly higher in calorie density and satiety by using more intact starches and beans and/or less fruits and veggies. The result is a more stable and more effective way of approaching the Sweet Spot and of being successful.
Bottom line…
Remember, it is also not all or nothing and there is a continuum between the McDougall regular program and the MWL program as also taught in the CD lecture at the 12-Day. Some people do full MWL during the Week and the regular McDougall program on weekends. Some people do the MWL program breakfast and lunch and the regular McDougall program for dinner. Our experience has taught us the most people do best in the beginning, and when losing the majority of their weight, to do the MWL program as some of the foods allowed on the regular McDougall program (bread products, dried fruit, nuts/seeds, sugars) can be triggers and result in binging. Instead, shifting the diet to more intact starches and beans and less veggies and fruit, shifts the calorie density and satiety of the diet higher.
- After this was done, Goose sent me the following comment...
"I was just thinking about how I’ve done this in practice, without really thinking about it.
I make a crockpot full of Mary's smashed beans (2 lb. dry pinto beans, onions, garlic, water, cooked all day on High, partially drained, then smashed) every few weeks and always have some on hand. When I’m feeling edgy, hungry, borderline craving, I take a big bowl and layer either brown rice or chopped pre-cooked Yukon golds in the bottom, followed by a thick layer of Mary's beans, a thick layer of broccoli and a topping of salsa. It comes out about 60/40 starches to veggies, and with fruit for dessert, it really works.
It follows your idea of bumping up the calorie density with intact starches and beans (we just happen to really like Mary's smashed beans instead of garbanzos), and it "smooths out" any feelings of excess hunger or tendency to stress-eat that I may be having."PS. I hope Artista is doing well. I would like to formally invite them, if they wish, to post and document their experience here in a journal. It would be fascinating to see if any of the above discussion, as well as the exploratory process of journaling and recording progress, helps them.
