Nuttin’ But Salads N=1 Experiment: Week 15 Summary

This steak is fully cooked. Doing it sous vide-style leaves it looking rare.

Still going strong. Weight is stable at 161.8 lb (73.5 kg). Two more weeks to go.

One Woman’s Experience With the Mediterranean Diet

Click the link below for details and good food photos.

“I never once felt like I was “dieting” on the Mediterranean eating plan. That said, my goal wasn’t weight loss — I was looking for improved energy levels and food that was filling and delicious. The Mediterranean diet accomplished both of those goals for me. I’d like to stick with it for a long time.”

Mediterranean Diet Protects Against Macular Degeneration

A view from Humphreys Peak, Arizona

I thought we knew this already. Another reason to love the Mediterranean diet. Macular degeneration is a leading cause of blindness in the developed world. Prevention is much better than treatment.

High adherence to a Mediterranean diet and regular physical activity seem to be protective factors for AMD in a Portuguese population. The effect of the diet is likely driven by the increased consumption of vegetables, fruits, and nuts.

Hmmm…No mention of heart-healthy whole grains.

A new salad ingredient for me, front and center: artichoke hearts

Good compliance for me this week. Nevertheless, weight is up to 163.8 lb (74.5 kg) compared to 160.2 lb (72.8 kg) last week. Last weeks weight was unusually low.

I feel good. Workouts are going well. No performance deterioration with this plant-based diet.

June 5 will by my four-month anniversary on this diet. I’ll stop at that point, after 17 weeks. That’s adequate as a proof-of-concept. Haven’t decided how I’ll transition off. Tempted to continue with only two meals daily, one being a large salad, but what of the other? Considering a protein (meat, chicken, fish, eggs) plus cooked vegetables (low-carb or not?) and/or legumes.

One More Reason to Lift Weight: Less Depressive Symptoms

I’m not surprised.

“Resistance exercise training significantly reduced depressive symptoms among adults regardless of health status, total prescribed volume of resistance exercise training, or significant improvements in strength.”

Humans Are By No Means the Only Species Getting Fat

I heard about this phenomenon years ago. It’s good to remember that obesity isn’t a simple straightforward process. Like Fanatic Cook, I wonder about pollution as a cause.

“A dramatic rise in obesity has occurred among humans within the last several decades. Little is known about whether similar increases in obesity have occurred in animals inhabiting human-influenced environments. We examined samples collectively consisting of over 20 000 animals from 24 populations (12 divided separately into males and females) of animals representing eight species living with or around humans in industrialized societies. In all populations, the estimated coefficient for the trend of body weight over time was positive (i.e. increasing). The probability of all trends being in the same direction by chance is 1.2 × 10 [to the minus 7th power]. Surprisingly, we find that over the past several decades, average mid-life body weights have risen among primates and rodents living in research colonies, as well as among feral rodents and domestic dogs and cats. The consistency of these findings among animals living in varying environments, suggests the intriguing possibility that the aetiology of increasing body weight may involve several as-of-yet unidentified and/or poorly understood factors (e.g. viral pathogens, epigenetic factors). This finding may eventually enhance the discovery and fuller elucidation of other factors that have contributed to the recent rise in obesity rates.”

Can Diet Improve Your Gingivitis or Periodontitis?

Yes...at least according to a tiny short-term study done in Germany. Only 10 experimental subjects. The researchers didn’t call it a paleo diet but that’s what it looks like to me.

Here’s their description of the food: “..low in carbohydrates, rich in Omega-3 fatty acids, and rich in vitamins C and D, antioxidants and fiber for four weeks.” How low in carbs? To a level “as far as possible to a level < 130 grams/day.” Click the link above for full diet details. By my reading, it qualifies as a paleo diet.

Certified paleo-compliant, plus high omega-3 fatty acids and low-carb

The researchers note in the body of their report that they can’t tell for sure which components of the experimental diet were most helpful, but they suspect it’s 1) the carbohydrate restriction, 2) increased omega-3 fatty acids, and 3) reduced omega-6 consumption.

Those three factors are at play in the both the Ketogenic Mediterranean Diet and Low-Carb Mediterranean Diet, both of which are options in my book, The Advanced Mediterranean Diet (2nd Ed.).

Here’s the study’s abstract for you science nerds:

Background

The aim of this pilot study was to investigate the effects of four weeks of an oral health optimized diet on periodontal clinical parameters in a randomized controlled trial.

Methods

The experimental group (n = 10) had to change to a diet low in carbohydrates, rich in Omega-3 fatty acids, and rich in vitamins C and D, antioxidants and fiber for four weeks. Participants of the control group (n = 5) did not change their dietary behavior. Plaque index, gingival bleeding, probing depths, and bleeding upon probing were assessed by a dentist with a pressure-sensitive periodontal probe. Measurements were performed after one and two weeks without a dietary change (baseline), followed by a two week transitional period, and finally performed weekly for four weeks.

Results

Despite constant plaque values in both groups, all inflammatory parameters decreased in the experimental group to approximately half that of the baseline values (GI: 1.10 ± 0.51 to 0.54 ± 0.30; BOP: 53.57 to 24.17 %; PISA: 638 mm2 to 284 mm2). This reduction was significantly different compared to that of the control group.

Conclusion

A diet low in carbohydrates, rich in Omega-3 fatty acids, rich in vitamins C and D, and rich in fibers can significantly reduce gingival and periodontal inflammation.
