Dehydration, therefore, starts a chain of many negative impacts and hot flashes are one of them. It is a common understanding that during the first few weeks of a keto diet, people experience huge weight loss. While some of the weight loss is the one from fats, a major portion of the weight is lost due to water loss. Around 3 to 4 lbs of water are lost during the first few days of a keto diet. With this huge amount of water lost, each and every segment of the body feels deprived of water, giving rise to hot flashes off and on.
Electrolyte imbalance accelerates hot flashes:
Electrolyte imbalance  and dehydration go side by side because when water is lost electrolytes are also lost leaving the body dehydrated. Tons of electrolytes are depleted from the body in this process. On a keto diet, the body is already short on carbohydrates.

Without the proper repletion of sodium, potassium, and magnesium along with water, the body gets heated up and that results in hot flashes on a keto diet.
Low blood sugar also induces hot flashes:
Low blood sugar levels are always associated with a low carbohydrate diet such as a keto diet. Hypoglycemia is experienced when blood sugar levels are quite low.

Due to the wide number of ketones in the body, hot flashes are felt on a keto diet.
