Weight loss

Burn stored fat as your primary energy source for effective weight loss.

Stable energy

No more blood sugar crashes - fat provides steady, consistent energy.

Reduced hunger

Fat and protein keep you satisfied longer, reducing cravings.

Ketones have anti-inflammatory properties that benefit overall health.

Keto flu refers to symptoms like fatigue, headaches, and irritability that some people experience during the first week of keto. It's caused by your body adapting to burning fat instead of carbs. Staying hydrated and getting electrolytes helps.
