The Root Cause of Stalled Weight Loss00:00:24
Dr. Cyus explains that most weight loss stalls are caused by insulin resistance and an inability to maintain ketosis. Insulin's primary function is to store energy, which effectively blocks fat mobilization from fat cells.
Using the BOS Ratio00:02:50
To track progress, he introduces the 'BOS Ratio'—dividing fasting blood sugar (mg/dL) by ketone levels (mmol/L). A ratio above 80 indicates insulin resistance, while 40-80 is optimal for weight loss. For severe health conditions, a ratio below 40 is recommended.
Dietary Adjustments and Supplements00:05:00
If your ratio is high, eliminate all sugar and starch, and increase your fat intake. Excessive lean protein can also act like sugar through gluconeogenesis, so prioritizing fats over lean proteins is critical. He also suggests using exogenous ketones like Ketone IQ to assist with metabolic transitions.
The Role of Fasting00:09:13
For those struggling with weight, true fasting (36+ hours) can help break plateaus. He emphasizes that the most important rule is to avoid 'celebrating' the end of a fast with a large meal, suggesting a small, nutrient-dense food like sardines instead.
