My doctor recommended keto for Hashimoto’s, but is my high blood pressure an issue?

Hashimoto’s disease is a problem of the immune system in which it attacks the thyroid. A poor diet can affect the immune system, so following a diet that is anti-inflammatory, such as keto, may help with this; however, note that you need to follow a healthy, well-formulated ketogenic diet, including vegetables but avoiding processed foods.

Regarding the blood pressure condition, studies have shown that a low-carb, high-fat diet is beneficial, but you will need to work with your doctor to help with management of blood pressure medications while transitioning to a ketogenic diet. On the ketogenic diet, the body excretes more sodium rather than retains it, so sodium needs are actually higher than on a standard diet.

How long does it take to get back into ketosis if I go (way) over on carbs?

This is very individual and depends on the type and amount of carbs that were consumed. It also depends on how long one has been on the keto diet or in other words, how adapted one is to keto. It can take anywhere from a few hours to a few days.

Struggling a little bit? It happens. Here’s some reading to help you stay the course:

Remember, you’re following a lifestyle, so while slips make you human, try to stick within your macros whenever possible and remind yourself of the benefits of keeping in ketosis. It’s worth it!

Can I play tennis while on the Keto diet?

Absolutely! There are no forms of physical activity that cannot be done on a full ketogenic diet. In fact, keto is being highly studied and used in high-performance athletes.

Some things to keep in mind:

  • When first starting keto, performance will typically decline.
  • Over several months, it should begin to improve – and even accelerate.
  • If you do not exercise or play tennis frequently to build cardiovascular endurance, then improvements in physical performance may not be seen, keto or not.
  • Make sure you are paying special attention to electrolytes and hydration, especially when exercising, as deficiencies of either would result in lack of energy and performance.

    PLEASE help me know more about keto! I am a “follow this recipe” type of gal. I need a book that lays it out step by step. Is there such a thing? Seems like everyone wants my money to tell me the best way to go keto….. Your recommendation would be ever so helpful. Thank you!!!

    I have regained weight after weight lost surgery. I think carbs are the culprit. Can keto be used after weight loss surgery?

    Thank you Amber. Is there a recommended book that “lays it out” as to how to start living keto? You know how much to eat at each meal, what to look for. I don’t fully understand macro’s etc. There are SO many books out there I would appreciate if you could recommend one that will start me on this journey in a “do A, B and C” kind of way. Again laid out like a recipe so I can follow the keto lifestyle more easily.
