Here some factors that influence fat loss and fitness

1. Basal Metabolic Rate (BMR)

This is the amount of calories an individual burns at rest to maintain normal bodily functions.

2. Carbohydrate Sensitivity and Insulin Response

A person’s level of sensitivity to carbohydrates directly affects an individual’s ability to lose body fat.

3. Digestive Ability

Efficiency of an individual’s digestive system to absorb and utilize nutrients.

4. Fat Cell Quantity.

Some individuals are born with more fat cells than others. The quantity of an individual’s fat cell increases but it cannot decrease. However, you can shrink the size of fat cells through a nutrition and exercise.

5. Limb Lengths

These are natural and can not be changed.

6. Muscle Fiber Type

Although we have predetermined number of muscle fibers, we have different types of muscle fibers. The differences between each person’s ratios of muscle fibers account for why some people make better endurance athletes while others become weightlifters.

7. Muscle Insertions

Muscles insert onto the same bones in all humans but the insertion points vary between individuals. Minute differences in insertion points create large increases in an individual’s mechanical advantage over others.

Heredity is a determinant whether an individual will have an easy (or difficult) time getting fit and healthy. However, results are not dictated by these factors but by adopting proper exercise and nutrition strategies.
