Stay hydrated. As carb intake is lowered, the kidneys will start dumping excess water being retained as a result of the former higher carb intake. Make sure to drink enough water to replace what gets lost. The old 6-8 glasses is a good rule, I guess, although just drinking to thirst will probably do the trick. If you find yourself getting headaches and muscle cramps, you need more water, and more minerals such as salt, magnesium and potassium, because the water loss also takes minerals with it. (See my low carb diet side effects page for more info).

Keto diets rely on an extreme technique to (temporarily) move the scale down a few pounds, and basically eliminates all joy associated with eating real food and living life. Since restriction for life is downright impossible: Cut back on ultra-processed, high-carb foods like sugary beverages and tons of refined grains, and fill up on more nutritious carb choices, like veggies, fruit, legumes, low-fat dairy, and 100% whole grains to maximize long-term weight loss, health, and happiness.


When you’re eating the foods that get you there (more on that in a minute), your body can enter a state of ketosis in one to three days, she adds. During the diet, the majority of calories you consume come from fat, with a little protein and very little carbohydrates. Ketosis also happens if you eat a very low-calorie diet — think doctor-supervised, only when medically recommended diets of 600 to 800 total calories.
This is fantastic! I don’t feel like I’m on a “diet” at all. There’s plenty of food, plenty of protein- (I’m an omnivore- a clean one tho), the juices and snacks are tasty. It’s even surprisingly easy to swallow a spoonful of MCT oil (medium chain triglycerides), it tastes like buttery coconut cream! If that seems strange, one could simply mix it in with the salad or shake it up in the juices. No problem.
In many developing countries, the ketogenic diet is expensive because dairy fats and meat are more expensive than grain, fruit and vegetables. The modified Atkins diet has been proposed as a lower-cost alternative for those countries; the slightly more expensive food bill can be offset by a reduction in pharmaceutical costs if the diet is successful. The modified Atkins diet is less complex to explain and prepare and requires less support from a dietitian.[54]
Eggs are a standout snack because they have one of the lowest energy-to-nutrient-density ratios of any food, as is noted in an article published in August 2016 in the journal Proceedings of the Nutrition Society. They’re rich in good fats (so long as you don’t skip the yolk!) and a solid source of high-quality protein: Each egg has 5 grams (g) of fat, 6 g of protein, and 0 g of carbohydrates, according to the Egg Nutrition Center. Plus, they’re inexpensive — about 20 cents per egg, the center says. Keep several hard-boiled eggs in your fridge, so you can easily grab one when you’re in need of a nutritious snack.
Achieving ketosis is a pretty straightforward, but it can seem complicated and confusing with all of the information out there.4If you want to learn more about ketosis and the scientific process around it, you can visit a very in-depth discussion about on Dr. Peter Attia’s website. Here’s the bottom line on what you need to do, ordered in levels of importance:
