Conclusion: Transitioning from Keto-adaptation to a Fat Burning State

Something additional to consider about the Weight Loss phase – because it takes two weeks to go through the majority of one’s keto-adaptive transformation to burning fat instead of carbs (sugars) for fuel, those who stick consistently to a low-carb (< 60 gram per day), ketogenic diet will feel consistently well. On the other hand, those who bounce back and forth between carb restriction and carb consumption will struggle more as their bodies repeatedly go through the cycle of fatigue associated with the early stage of keto-adaptation to a low-carb state.

One final point on the Maintenance phase – maintenance will present a different picture as each individual needs to determine a safe personal level of carbohydrate tolerance; that threshold below which they can sustain their losses and stay lean. For most patients at JumpstartMD, that will still require carbohydrate restriction but typically at a level closer to 100-150 grams per day rather than the 50-60 grams per day they followed in the Weight Loss phase. That said, for those who are more “carb sensitive” and either gain weight more readily in response to carbohydrates or have health risks (low HDL, high triglycerides, pre-diabetes or diabetes) associated with carbohydrate intake, we would consider greater carbohydrate restriction in the Maintenance phase – closer to that 50-60 grams per day.
