How Your Metabolism Changes
When you begin to change how much you eat and move, changes to your metabolism will be reflected by more than weight loss because your metabolism does more than influence body composition.
The biochemical process is constantly regulating various bodily functions like temperature, hormones, and blood glucose levels. Your metabolism does some of this work when you’re not doing much at all, like when you’re resting or asleep.
There are a lot of individual factors that influence metabolism. Everyone’s metabolic rate is different and in fact, your metabolic rate will change throughout your life. Metabolism is affected by sex, age, conditions like pregnancy, illness, injury, and medications.
When you make certain changes to your lifestyle, such as exercising more and eating less, your metabolism will respond in a number of ways—some of which won’t necessarily show up when you step on the scale.
On example is how your body handles glucose. According to the American Association of Clinical Endocrinologists, impaired glucose tolerance often shows up as a fasting blood glucose measure above 89 mg/dl. This may be a sign of a metabolic condition like type 2 diabetes.
If you have any other indicators of metabolic syndrome, making changes to your diet and activity level can reduce or even eliminate signs and symptoms such as:
- Elevated blood glucose
- High blood pressure (hypertension)
- High waist to hip ratio
- High blood triglycerides
- Low HDL cholesterol
If you’re on a very low-carb diet (under 50 grams of carbohydrate per day), these changes may show up fairly quickly once your body adapts to using fat for energy instead of glucose from carbohydrates—a state called ketosis.
