Everyone seems to be fasting. Do I need to fast to lose weight?


To answer your question, no. Fasting is a strategy that has shown to offer many health benefits including weight loss. Many people obtain these benefits by fueling off of fat instead of sugar with just the ketogenic diet alone. If you are feeling awesome and meeting your personal health goals, then feel free to leave it out.

Why do I smell ammonia in my nose after working out?

We ask nutritionist about fasting, ammonia, and food allergies - stretching before or after a workout

There are multiple reasons this could be happening, but specifically when one is new and un-adapted to a low-carbohydrate diet, when exercising, the muscles are short on glucose for fuel and the body is breaking down and metabolizing protein instead. This, in turn, results in the ammonia smell.

Other potential reasons for that ammonia smell:

· New to keto and not yet adapted to utilizing fat for fuel
· Too much protein intake
· Not enough fat
· Not enough fluid intake – dehydrated
· Not enough vegetables
· Low potassium – FYI, veggies have a lot of potassium
· History of kidney or liver conditions – consult with your doctor

Athletes participating in intense workouts should consider increasing carbs just a bit at night, which will supply some glycogen to use as energy during physical activity. Many athletes are able to consume generous amounts of carbohydrate (50-100 gm/day) and maintain ketosis, as exercise has been shown to improve insulin sensitivity and utilizes carbs as fuel more efficiently.

    I have a question for her…I know this is a bit specific, but I’d really like her input. I’m raising my 2 yr old daughter on keto and would like her to be able to eat eggs. She tolerates a small amount of egg fine, but if she gets too much she will have a strong vomiting reaction approximately 8-12 hours later. She has seen an allergist who has been of little help. Her skin allergy test was positive for an egg allergy and her blood test was negative for an egg allergy. Is there anything we can/should do, or do we just need to wait and pray that she outgrows it?

      Egg allergies are very common. Her reaction suggests she should stay FAR away from eggs. I’d also revisit this topic with your physician for advice.
