What Happens If You Eat No Carbs for A Week

Cutting out carbs entirely for just 1-2 days can lead to several noticeable effects on the body:

You will likely experience an initial drop in energy levels, as your body is deprived of its main source of fuel - glucose from carbohydrates. However, your body will adapt by entering a state of ketosis, where it starts burning stored fat for energy instead. This can result in rapid weight loss, mostly from shedding water weight.

You may also experience side effects like weakness, fatigue, dizziness, headaches, and even nausea and vomiting as your body adjusts to running on ketones instead of glucose. This is sometimes referred to as the "keto flu". Constipation is also common due to the lack of fiber from cutting out carb-rich foods.

Over time, your mental focus and energy levels may improve as your body becomes more efficient at using ketones for fuel. However, your mood could become more volatile, as low-carb diets can temporarily lower serotonin levels in the brain.

It's important to note that while a very short-term low-carb diet can lead to rapid initial weight loss, sustainable long-term results typically require a more moderate, balanced approach.
