Most people don’t need another weight loss plan.
They need a maintenance plan.
As an obesity medicine physician, one of the most important lessons I’ve learned is that weight loss and weight maintenance are different skills.
Many people have already proven they can lose weight. They’ve followed the diet, joined the program, tracked the calories, and seen the scale move.
The harder question is:
Who do you have to become to maintain that weight loss five years from now?
In medicine, we spend a lot of time talking about outcomes: pounds lost, A1c improved, cholesterol lowered.
Those metrics matter.
But lasting change happens at a deeper level.
James Clear popularized the concept that “every action is a vote for the type of person you wish to become.” His work on identity-based habits argues that sustainable behavior change starts with identity, not outcomes. The goal isn’t to run a marathon. It’s to become a runner. The goal isn’t to lose weight. It’s to become a person whose daily habits support health. (James Clear)
This aligns with what I see in practice.
The patient who maintains a 50-pound weight loss rarely relies on willpower forever. They gradually build systems, routines, environments, and relationships that support a different way of living. As Clear writes, we don’t rise to the level of our goals; we fall to the level of our systems. (James Clear)
The National Weight Control Registry, which has followed more than 10,000 people who successfully lost significant weight and kept it off, found that long-term success is associated with ongoing behavioral practices, not a temporary period of dieting. (Wikipedia)
This is why, in my practice, we start with a person’s “North.”
What do you value?
Who do you want to become?
What kind of life are you trying to build?
Then we work backward.
Because the real goal is not weight loss.
The real goal is becoming the person who can maintain it.
Stay North
