Dr. Boz [Annette Bosworth, MD] - The keto mistake I wish I could undo

Short Summary

Main recommendation: Dr. Boz (Annette Bosworth, MD) advises keto adapters to avoid the early mistakes she made, especially staying on high-fat, three-meal eating for months, using keto desserts or fat bombs for comfort, and measuring ketones only occasionally. The central idea is to move on from the initial keto phase by tightening the eating window and checking circulating ketones with a blood test. Her personal account is that a ketogenic diet, started with her mother, produced a 70 percent drop in her mother's cancer and 10 pounds of weight loss for Dr. Boz over six weeks.

Key Points

• Staying in the early high-fat, three-meal phase for months was a mistake; she says it should have lasted only four to six weeks before moving to two meals a day.
• Keto desserts and fat bombs are discouraged as emotional substitutes; she compares replacing sweets with keto desserts to telling an alcoholic to switch from whiskey to wine.
• Urine ketone strips show ketone production, but a finger-prick blood test is needed to confirm circulating ketones, since urine readings can fall as the body adapts.
• When ketones in circulation dropped below 0.5, she should have tightened her eating window, which she identifies as time-restricted eating.

Details Worth Noting

• Concrete instructions:
  • Use urine ketone strips first thing in the morning as an initial check that ketones are being made.
  • Do not wait a year to test blood ketones after becoming keto adapted; prick your finger to confirm ketones are circulating.
  • If circulating ketones fall below 0.5 after moving to two meals per day, shrink the eating window (time-restricted eating) rather than waiting.
  • Move the two meals earlier in the morning, overlapping the morning rise in blood glucose, to stimulate metabolism and get a higher, longer wave of ketones.
  • Replace the after-meal sweet habit with non-food activities: board or card games, praying, writing a gratitude list, playing with a dog, or doing puzzles.
  • For finger pricks, use the side of the finger with a spring-loaded lancet to reduce pain.
  • Watch the video before grocery shopping after discarding carbs, as she says it saves money.
• She says the first weeks of keto raise energy, immune function, and metabolism because cholesterol-based fat hormones are replenished and become active.
• Her blood sugar before keto was spiked by processed foods; on keto with about 20 total carbs per day, her blood sugar lowered.
• She notes that a missed meal early on should have been a clue that her body was adapting and she needed to progress.
• Her morning blood sugar remained fairly high even when she skipped breakfast, which she attributes to a half-meal-like rise in glucose.

Bottom Line

The early keto results are real, but the approach must evolve: after the initial weeks, reduce meals, shorten the eating window, and confirm ketones with a blood test rather than relying on urine strips or sweet substitutes. This is one physician's personal experience and not professional medical advice.
