what if human BMR adjusts to prior caloric intake?
After our previous discussion in this thread several months ago, I delved into the research. I now wholeheartedly believe Brute is correct. CICO theory (low cal diets + increased activity) does work on large scale, but only temporarily because of the above effect. CICO treats a symptom, not the cause.
I started the process with above average knowledge base of human biological systems, but after only a few weeks of research came to the conclusion metabolic syndrome is a hormonal disease. One brought on by the fatal combination of low fat/high carb (subpart high fructose corn syrup usage) and frequent eating. The theory is well summarized here
This lead me into the rabbit hole of polyunsaturated fats and cardiac disease. This research is an ongoing process with less conclusive science, but I'm "sold" enough to cut them from my diet. Further research may show them to be nearly as harmful as transfat.
Personal changes as a result: I was already intermittent fasting (go c_L), so no changes there. However, I did completely remove refined sugars from diet. I kept grains and although I dont really eat fruits individually, they are not taboo if an ingredient to a meal. Obviously not a ketogenic diet, although relatively high fat/low carb. I also cut out polyunsaturated fats, now use grass fed butter and olive oil very
liberally with meals. The added fat intake is likely increasing my overall caloric intake even without a desert(I'm not counting, its a hassle). I also quit using a no-calorie sugar substitute in my morning coffee(s) as they have been shown to cause insulin spikes without calories. Now I truly have a once daily insulin spike, which is likely reduced in amount thanks to more fat and less simple carbs. Net result is a 10 lb weight loss in two months without change to activity.
The reason for my initial interest was a poor lipid panel with annual check up, and BMI of 29. For study n=1, below was my lipid panel results from March of this year. I will continue the above changes and report lipid panel next year, along with any continued weight loss.
