There was a post on personal fat threashold just after the last post on this thread:
https://optimisingnutrition.com/personal-fat-threshold/

I checked my fasting glucose on three consecutive days, the first two were 96 and the third (after a Friday night where I drank), was 102. These seem dangerously close to the limit.

About me: Age 51, 5'10", weight varying between 140-147 lb (giving a BMI of 20-21 which is probably overly high as I have some muscle but the NHS healthy range is 18.5-25). I have two meals, 6 hours apart, don't snack and don't get hungry. Daily, I do half-an-hour of stretches/body weight exercises, a couple of weight exercises to failure and walk 2 miles.

I tend to eat <60g carbs a day and have a good amount of protein (I've not measured it but my vegetarian wife moans about the size of the lumps of meat on my plate). It seems the only way to maintain weight is high fat which is contrary to Marty's thinking.

I don't know what to do.
Not worry? Increase protein even more? Increase carbs a bit more? Combine carbs and fat? Eat 3 meals? etc.
