How Dr. Colbert approaches weight loss
After more than 40 years in medicine, Dr. Colbert has seen that most people do not fail diets; diets fail people. When meals keep blood sugar and insulin on a roller coaster, hunger wins. His plan works with your body instead:
- Eat in the Keto Zone. Build meals on healthy fats, moderate protein and plenty of non-starchy vegetables so your body learns to burn fat for fuel.
- Quiet the cravings. Steady blood sugar means fewer energy crashes and less late-night snacking. Try low-carb swaps for cornstarch in your favorite sauces.
- Use fasting wisely. A shorter eating window can help, as long as you avoid the common intermittent fasting mistakes.
- Lower stress. High cortisol drives belly fat. These daily habits to lower cortisol help.
- Invite God into the process. Self-control is a fruit of the Spirit. Many readers lean on these Bible verses for weight loss.
I can do all things through Christ which strengtheneth me. (Philippians 4:13, KJV)
