Can you brea your metabolism with crash dieting?

You can't break it, but you can cause metabolic adaptation. When you eat too few calories, your body slows down its processes to conserve energy. This makes it harder to lose weight over time and is why "starvation diets" almost always backfire.

Q2: What is the most common metabolic disease?

Type 2 Diabetes is the most prevalent metabolic disease globally. It is characterized by insulin resistance, where the body's cells no longer respond effectively to insulin, leading to high blood sugar.

How does age affect metabolism?

Historically we thought metabolism plummeted in our 20s. However, recent research suggests it remains relatively stable from ages 20 to 60. The slowdown we feel is usually due to a loss of muscle mass and a decrease in daily movement, not a biological failure.

Q4: What causes metabolic acidosis?

Common causes include diabetic ketoacidosis (DKA) kidney failure and lactic acidosis (often from intense exercise or certain medications).

Q5: Is there a fast or slow metabolism gene?

Genetics play a role (about 10-15%), but they are not destiny. Most fast metabolisms are actually the result of high NEAT (fidgeting/moving) and high muscle-to-fat ratios.
