Overweight individuals with metabolic syndrome, insulin resistance, and type 2 diabetes are likely to see improvements in the clinical markers of disease risk with a well-formulated very-low-carbohydrate diet. Glucose control improves due to less glucose introduction and improved insulin sensitivity. In addition to reducing weight, especially truncal obesity and insulin resistance, low-carb diets also may help improve blood pressure, blood glucose regulation, triglycerides, and HDL cholesterol levels. However, LDL cholesterol may increase on this diet.

Now is the time to forget the 1980s strategy of low-fat/reduced-fat/fat-free. When you're assembling your keto diet food stash, go full-fat. And don't stress over the dietary cholesterol content, a factor of how much animal protein you eat, suggests a study published in The Journal of Nutrition. For the healthiest blood cholesterol levels, instead focus on consuming a higher ratio of unsaturated fats (flaxseed, olive oil, nuts) to saturated fats (lard, red meat, palm oil, butter).
But beyond that, experts aren't convinced that the keto diet has any other scientifically-proven health benefits. In fact, it may have some distinct downsides. If you follow the keto diet incorrectly, for example (like by eating lots of saturated fats, versus healthy unsaturated fats), you're at risk of raising your cholesterol levels. “The best strategy to keep your heart healthy is to get as much fat as possible from unsaturated sources such as olive, avocado and canola oils, nuts, seeds, avocados, and olives," says Ansel.
Just because keto is a high fat diet doesn't mean you should rely on large portions of fatty meats to hit your daily fat quota. “It’s not about eating an 8-ounce steak,” Mancinelli says. “Instead, have a 3-ounce portion of steak with half an avocado on the side.” That’ll help you meet your fat needs without overdoing it on the protein or potentially harmful saturated fats.
Drink lots of water. This is especially crucial on a low carb or keto diet. Why? When you eat carbohydrates, your body stores the extra as glycogen in the liver, where they are bound to water molecules. Eating low carb depletes this glycogen, which allows you to burn fat – but it also means you are storing less water, making it easier to get dehydrated. Instead of the traditional recommendation of 8 cups of water per day, aim for 16 cups when following a low carb lifestyle.
The keto diet doesn't discriminate against all you cheese lovers. While we're often told to avoid dairy because of its high fat content, this is precisely what makes it an ideal keto food group. As usual, stick to the low-carb options and avoid anything that adds unnecessary calories via flavorings or sugars. Listed in order of lowest to highest carb content per 1-ounce serving, the best dairy products for the keto diet include:
Very happy to have stumbled across your blog site (during a recipe search)  only to realise that I have recently purchased 2 of your books (I'm in Australia). Both of which I like.  I have been doing this way of eating since February, switched from WW which was progressing slowly and I was often hungry. I am never hungry on this plan and I am finding it so much easier. And I am losing weight twice as fast. After about 2 1/2 months doing Keto I realised that the lists I was using for a resource for net carbs in foods was completely wrong. It said mushrooms was 0.3 net carb per 100g and I was happily having 200g thinking it was 0.6g and it wasn't. I ended up checking some lists against the USA Agriculture list and found all were wrong.  So I started to make my own list using that website. This was a bit of a pain but at least I knew it was accurate. Anyway,  I found your site and could stop doing my list. YAY!  🙏 Thank you so much for providing accurate information that you have referenced and for all the other guides and recipes you have shared.  I really wish these guides were in my books though (I have your latest book), so can you please consider for the next book 😁. I had to print them after saving it to MS word for a friend (that has also bought a book)  and it's pages of poorly edited A4 paper.  Many thanks again 🙏
Also, consider supplementing with the amino acid leucine, as it can be broken down directly into acetyl-CoA, making it one of the most important ketogenic amino acids in the body. While most other amino acids are converted into glucose, the acetyl-CoA formed from leucine can be used to make ketone bodies. It’s also present in keto friendly foods like eggs and cottage cheese.
