Health Benefits of Body Fat

1. Energy Storage:
Fat stores energy that the body can use during periods of calorie deficit.

2. Thermal Insulation:
It helps regulate body temperature by providing insulation.

3. Organ Protection:
Fat acts as a cushion for vital organs, protecting them from physical trauma.

4. Hormone Production:
Body fat is critical for producing hormones like estrogen, testosterone, and leptin, which regulate metabolism and reproduction.

5. Nutrient Absorption:
Dietary fat aids in the absorption of fat-soluble vitamins (A, D, E, K).

Consequences of Low Body Fat Percentage

1. Hormonal Imbalances:
Extremely low fat can disrupt hormone production, leading to menstrual irregularities in women and low testosterone in men.

2. Weakened Immunity:
Insufficient fat may impair the immune system, increasing the risk of infections.

3. Bone Health Issues:
Low fat levels can decrease bone density, increasing the risk of fractures.

4. Energy Deficiency:
Without adequate fat stores, the body may struggle with fatigue and decreased physical performance.

5. Impaired Thermoregulation:
Too little fat can make it harder to maintain body heat in cold environments.

Consequences of High Body Fat Percentage

1. Cardiovascular Risks:
Excess body fat, especially visceral fat, increases the risk of heart disease, hypertension, and stroke.

2. Insulin Resistance:
High fat levels can impair insulin function, leading to Type 2 diabetes.

3. Joint Stress:
Extra weight puts stress on joints, increasing the risk of arthritis and joint pain.

4. Sleep Disorders:
Obesity is linked to sleep apnea and poor sleep quality.

5. Inflammation and Chronic Diseases:
Excess fat promotes inflammation, increasing the risk of diseases like cancer and fatty liver disease.
