This episode is brought to you by LMNT! What is LMNT? It’s a delicious, sugar-free electrolyte drink mix. I’ve stocked up on boxes and boxes of this and usually use it 1–2 times per day. LMNT is formulated to help anyone with their electrolyte needs and perfectly suited to folks following a keto, low-carb, or Paleo diet. If you are on a low-carb diet or fasting, electrolytes play a key role in relieving hunger, cramps, headaches, tiredness, and dizziness.
LMNT came up with a very special offer for you, my dear listeners. For a limited time, you can get a free LMNT Sample Pack with any purchase. This special offer is available here: DrinkLMNT.com/Tim.

This episode is also brought to you by Athletic Greens. I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1 by Athletic Greens, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so. I do my best with nutrient-dense meals, of course, but AG further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system.
Right now, Athletic Greens is offering you their Vitamin D Liquid Formula free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit AthleticGreens.com/Tim to claim this special offer today and receive the free Vitamin D Liquid Formula (and ten free travel packs) with your first subscription purchase! That’s up to a one-year supply of Vitamin D as added value when you try their delicious and comprehensive all-in-one daily greens product.
