  • [2:30] Rachel’s recommendation for the best way to nourish your body with food to rebuild. She stresses the importance of choosing a diet you can adhere to long-term, gathering sufficient information to know if the diet is a good fit, and following what she calls the Whole Food Rule (Eating 80%-90% foods that either grew from the earth or once had a face).
  • [4:20] Diet is not the only crucial component when it comes to changing the general composition of your body. 
  • [7:30] Rachel explains the difference between scale weight loss and body size weight loss.
  • [8:00] Proper scale use consists of taking a weekly average, not daily fluctuations. Check out this blog post for how to use the scale properly.
  • [9:30] There is a popular saying that ‘muscle weighs more than fat,’ which is technically incorrect (i.e. 1 lb of margarine = 1 lb of butter) but as far as health goes, fat and muscle have different effects on physiology.
  • [10:10] Muscle burns carbs and assists in all areas of fitness, whereas fat does not.
  • [11:00] In my opinion, measuring inches lost (or noticing changes in how your clothing fits) is actually much more of a reliable measurement of progress than the scale. Body tape measurements are a great tool for this.
  • [15:30] How long should it take to lose weight on keto?
  • [15:40] Everyone’s body is different, which means the rate of weight loss is going to be different. Overall health, current body composition, activity level, and diet are some of many factors.
  • [17:00] Initial weight loss due to water weight can cause dehydration and keto flu symptoms, so make sure to hydrate and get electrolytes!
  • [18:10] Here’s what a few studies have shown in regard to losing weight on the ketogenic diet.
  • [20:00] As you get closer to your goal weight, weight loss slows down. As your weight decreases, and you become a smaller person, your total daily caloric needs also decrease. This is known as metabolic adaptation or adaptive thermogenesis. - part of fat loss. Go here: Refeed and Diet Break Episode for more on adaptive thermogenesis.
  • [21:00] Appropriate rates of weight loss on the scale and body size measurements.
  • [23:00] Losing fat isn’t always reflected on the scale. 
  • [23:00] Rachel’s thoughts on Exogenous Ketones? See: Episode with Ryan Lowery
  • [24:40] Quality matters and they are not a magic weight loss or fat loss drink
  • [25:00] Even if you read 0.2-0.4 ketones is that beneficial? Is it necessary to be above 0.5 to achieve the benefits?
  • [26:10] Registering any level of ketones can be beneficial. Different levels may bring in different amounts of added benefits, such as mental focus and clarity.
  • [28:00] What about people who are on keto for a while and experience elevated blood glucose levels?
  • [28:30 ] Adaptive Glucose Sparing (aka physiological insulin resistance), in which the muscles learn to reject sugar as a fuel source. 
  • [30:00] The Dawn Phenomenon, in which blood sugar is highest in the morning.
  • [32:00] HOMA-IR: the homeostatic model assessment of insulin resistance, is your body maintaining its essential systems in balance or in equilibrium. What happens is insulin is working against glucose in an attempt to keep blood sugar levels stable, or in homeostasis.
  • [33:00] Dr. Ted Naiman talks about HOMA-IR.
  • [37:00] Rachel talks about the underrated effects of stress on blood glucose levels.
  • [38:00] CGM and stress in this episode with Mike Mutzel
  • [39:30] False reading on your glucose monitor may occur because of outside fragrances, dehydration, and environmental interference. Unexpected readings should be multiplied and averaged.
