Ketosis is due to

Options

A. High insulin level
B. Low insulin level
C. Low thyroxine level
D. Low level of glucagon

Answer

**Step-by-Step Solution:**

1. **Understanding Ketosis:**
- Ketosis is a metabolic state characterized by elevated levels of ketone bodies in the blood. It occurs when the body does not have enough glucose to use for energy.

2. **Role of Insulin:**
- Insulin is a hormone that regulates glucose levels in the blood. When insulin levels are high, glucose can enter the cells easily, providing them with energy.

3. **Low Insulin Levels:**
- In conditions where insulin levels are low, the body cannot effectively utilize glucose for energy. This leads to a situation where the cells are deprived of their primary energy source.

4. **Alternative Energy Source:**
- To meet its energy requirements, the body begins to break down fat stores. This process is known as lipolysis, which leads to the production of fatty acids.

5. **Gluconeogenesis:**
- The fatty acids are then converted into glucose through a process called gluconeogenesis. However, this process also produces ketone bodies as by-products.

6. **Accumulation of Ketone Bodies:**
- When ketone bodies accumulate in the blood due to excessive fat breakdown and insufficient insulin, it leads to a condition known as ketosis.

7. **Conclusion:**
- Therefore, ketosis is primarily caused by low levels of insulin, which prevents glucose from being utilized effectively, prompting the body to rely on fat breakdown for energy.

**Final Answer:**
- Ketosis is due to low insulin levels.
