Explanation:
Depending completely on fat resources and depriving carbohydrate sources will lead to a metabolic condition called ketosis. Excessive ketosis results in the production of ketone bodies and acidic blood due to excessive fat metabolism.
Fatty acids cannot cross the blood brain barrier system and cannot reach the brain cells. Although the ketones can break the barrier and reach the nerve cells to provide energy in the brain cells, this is still considered not a healthy option.

So, a well-balanced diet including all the essential nutrients with regular exercise and a good lifestyle is the key to lose weight for Keith.
