"Those with type 1 diabetes should avoid a ketogenic diet," warns Joseph Galati, MD, a hepatologist at the Liver Specialists of Texas in Houston, "Many patients with type 1 diabetes have some degree of renal impairment, and handling the build-up of ketones and acids in the body may cause too much stress on the kidneys. Of course, any pregnant women with diabetes, especially those requiring insulin should avoid such an extreme diet given the low glucose levels will be a constant [health] threat."
Recent studies have also shown that garlic supports blood-sugar metabolism, and helps control lipid levels in the blood. What’s more? Eating garlic can help boost your immune system, help ward off heart disease, fight inflammation, increase memory retention, and lower blood pressure, so consider adding some to your next meal. At the very least, it is preferable over salt, which can lead to water weight gain and bloating.
Beans can help boost feelings of fullness and manage blood sugar levels, making them an excellent ally in your weight loss battle. In fact, a recent study published in The American Journal of Clinical Nutrition found eating one serving a day of beans, peas, chickpeas or lentils could contribute to modest weight loss. And if you need another reason to bulk up on beans, remember that the fiber and protein-rich legumes are other excellent sources of genistein—the same compound found in peanuts and lentils that aids weight loss.
How would you like to take all the great weight-loss results you’ve just read about—and double them? That’s what happens when you supplement your diet with a combination of vitamin D and calcium, according to a Nutrition Journal study. Just four weeks into the 12-week experiment, subjects who had taken these two nutrients—found in abundance in some yogurts—lost two times more fat than the other group! To get similar results at home, start your day with one of these Best Brand-Name Yogurts for Weight Loss.
The first meta-analysis worth noting collected the data from 10 randomized trials comprising 1376 participants in total.  After analyzing the research, a key relationship emerged between dietary carbs and blood sugar levels. In short, the researchers described their finding thus: “the greater the carbohydrate restriction, the greater glucose lowering…” 
The sad truth is that conventional ideas – eat less, run more – do not work long term. Counting calories, exercising for hours every day and trying to ignore your hunger? That’s needless suffering and it wastes your time and precious willpower. It’s weight loss for masochists. Eventually almost everyone gives up. That’s why we have an obesity epidemic. Fortunately there’s a better way.
Since avocados are packed with nutrients and healthy fats that can stimulate weight loss, it’s no surprise that avocado oil acts in a similar fashion. When Penn State University researchers compared those who consumed avocado oil with those who consumed a flax-safflower oil blend, they found that those who used just three tablespoons of avocado oil daily lost nearly two percent of their belly fat in just one month.
On the flip side, hypos can be an issue, especially early on…and if you treat them too aggressively, they could knock you out of ketosis. I remember my first 3 weeks on keto, my CGM trend line hugged a blood sugar of around 80. It was glorious, but I had to reduce insulin substantially through trial and error and felt like I was low every five seconds.
While there isn't "a" Mediterranean diet, most versions share many of the same principles. According to Oldways, the nonprofit food think tank in Boston that helped develop a Mediterranean food pyramid, you'll load up on fruits, veggies, whole grains, nuts and legumes; eat plenty of fish and seafood; get a little poultry, eggs, cheese and yogurt; and mostly pick at sweets and red meat. And don't forget a drizzle of olive oil and (if you want) a couple glugs of wine.
Sleep enough – for most people at least seven hours per night on average – and keep stress under control. Sleep deprivation and stress hormones raise blood sugar levels, slowing ketosis and weight loss a bit. Plus they might make it harder to stick to a keto diet, and resist temptations. So while handling sleep and stress will not get you into ketosis on it’s own, it’s still worth thinking about.
