Jeff Winkler described his first weeks of intermittent fasting:
Annual physical July 2nd , HDL 46, cholesterol 243, LDL 177. Doc pushing for statins. I’ve been taking 5000 IU D3, some zinc, eating vaguely low carb. Had a kid a couple years ago. Watched Eat Fast, Live Longer. Was blown away.
Decided to try intermittent fasting and use $500 USB ultrasound device (BodyMetrix) for feedback. Conclusions after three weeks:
- It’s not hard. I’m eating within an 8-hour window. Usually try to eat first food at 9 AM, close the window 8 hours after. I’m hardly ever hungry. Now it’s like “oh, it’s 9, guess I should eat”. I’m not eating specially or restricting my intake.
- Losing weight. About 237->231 in 20 days.
This shows fat loss from the thigh and waist; the chest measurements vary too much to see a trend. The BodyMetrix data and the weight data (237–>231) confirm each other. He also used an Omron measurement device that uses impedence to measure body fat. You hold it in your hands. Its data were too noisy to conclude anything.
All in all, Winkler’s scale did a good job of detecting weight loss, the BodyMetrix device added a bit (confirmed the weight loss was due at least partly to fat loss), and the Omron device added nothing. The BodyMetrix device is advertised with the claim “no embarrassing pinching” but I’m sure pinching (with calipers) to measure skinfold thickness would have been more accurate.
