…but Dave (Alvin & Chipmunks humor)
I have found through experimentation eating potato’s (resistant starch) only keeps me in ketosis and it feeds the gut bugs (microbiome) also, something you cannot do with fat and meat. A little butyrate from grass fed butter helps also.
Eating potato’s only for two weeks appears to deplete glycogen stores enough to burn body fat much faster than eating fat and meat alone because it is not turning into glucose but instead turning into short chained fatty acids.
Even if you don’t have multiple copies of the AMY1 gene it should still work because your not breaking down starch into glucose!
 Effect of Low-Fat vs Low-Carbohydrate Diet on 12-Month Weight Loss in Overweight Adults and the Association With Genotype Pattern or Insulin Secretion The DIETFITS Randomized Clinical Trial February 20, 2018 …More
Key Points (from above citation):
Question: What is the effect of a healthy low-fat (HLF) diet vs a healthy low-carbohydrate (HLC) diet on weight change at 12 months and are these effects related to genotype pattern or insulin secretion?
Findings: In this randomized clinical trial among 609 overweight adults, weight change over 12 months was not significantly different for participants in the HLF diet group (−5.3 kg) vs the HLC diet group (−6.0 kg), and there was no significant diet-genotype interaction or diet-insulin interaction with 12-month weight loss.
Meaning: There was no significant difference in 12-month weight loss between the HLF and HLC diets, and neither genotype pattern nor baseline insulin secretion was associated with the dietary effects on weight loss. …More
