As far as weight loss is concerned, I have heard great things from many who have switched to eating the Mediterranean way. Some were able to see results in just a few weeks…feeling better and losing a moderate amount of weight. From my personal experience, the only time I wasn’t eating the Mediterranean way was during my early years in college. I attended college in Michigan, and naturally, I ate whatever was available in the school cafeteria. Freshmen year, I gained nearly 30 lb. But lost it all without much effort in 2 months, when I returned home that summer and started to eat Mediterranean again. It’s important to say that the Mediterranean lifestyle is really a way of living, and one we commit to longer term, not necessarily a quick diet for the sake of losing weight. I always mention too that I have no medical or professional background to lend in the area of weight loss. If that is priority, a registered dietitian or someone with that kind of experience would be of help.
There are so many tricks, shortcuts, and gimmicks out there on achieving optimal ketosis – I’d suggest you don’t bother with any of that. Optimal ketosis can be accomplished through dietary nutrition alone (aka just eating food). You shouldn’t need a magic pill to do it. Just stay strict, remain vigilant, and be focused on recording what you eat (to make sure your carb and protein intake are correct).
Normal dietary fat contains mostly long-chain triglycerides (LCT). Medium-chain triglycerides are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolised. Their use allows for a diet with a lower proportion of fat and a greater proportion of protein and carbohydrate, leading to more food choices and larger portion sizes. The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil. Consuming that quantity of MCT oil caused abdominal cramps, diarrhoea and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints. The classical and modified MCT ketogenic diets are equally effective and differences in tolerability are not statistically significant. The MCT diet is less popular in the United States; MCT oil is more expensive than other dietary fats and is not covered by insurance companies.
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…” 
“A little forethought can go a long way,” says Monica Auslander Moreno, MS, RD, LDN, consultant at RSP Nutrition. “In my practice I help clients stay on track with weekly meal prep planning guides or prep survival kits. If you fail to plan, you plan to fail,” she explains. By planning your meals in advance, you're less likely to give into temptation or consume extra calories from hidden oils, sugar, and sodium in many take-out dishes.
A 2016 study in The Lancet Diabetes & Endocrinology journal that analyzed data from Predimed – a five-year trial including 7,447 adults with Type 2 diabetes or at risk for cardiovascular disease who were assigned either a Mediterranean diet supplemented with olive oil, the same diet supplemented with nuts or a control diet – found that people on the Mediterranean versions added the fewest inches to their waistlines. The olive oil folks lost the most weight.
As Tammy points out, diets are diets, and many people nowadays think/feel that diets are a “time/value-based goal”. “If I just get my weight down, or if I just fix this, then I’ll be all set…” WRONG!!! There in lies the first problem. How long can it be maintained? Well that’s a good point. The real question is, how long is one committed to changing their life, and how strong is their desire to do it. ALL things that one wants to change in life, require a change in to the way their living and/or perceiving life. They require a life-style change. One could attempt a Mediterranean diet, and yet relapse back to “normal” eating after 3mos, 1yr, 3yrs, etc.. It doesn’t really matter if the change isn’t first on the mental and emotional level. Unfortunately, many first-world daily diets (namely American) incorporate many foods that are addictive which can cause cravings. And yes, the cravings are scientifically prove-able, and have been proved. We grow up thinking that it’s “normal” to have your cake (since its the carb of debate lol) and eat it too, because why?… Well because that’s how they were raised. Simply as that. Conditioned living if you will. There are many cultures on this planet that DO NOT grow up eating as many carbs and sweets as the American Diet, and do perfectly fine without all the sugars and carb cravings. And incidentally, they also lead healthier lives too… Go figure.
Either there are very few participants in the studies, they don’t have an even number of males vs. females, or they don’t last but a few months. One study only looked at 28 people; only 21 completed the study and 20 of these participants were men. On top of this, they were only followed for 16 weeks. Okay, so we see that 20 men can limit their carbohydrates severely for 4 months and lose weight which automatically makes their A1c come down. Great! So, the real question is, how long can these 20 men stay on this diet for the rest of their lives? How long would you like to go without eating any fresh fruit? I’m craving some now, so I’m taking a break to go grab a snack now!
My Husband and I started doing Keto July 2018. We got over weight after we got out of the Marine Corps. It has been hard to workout because I became disabled, but my diet was not good. After our friend Amber recommended your site and support group, we found a lot of helpful information to get us started on a successful journey. So far it’s been one month and we have lost 18 pounds each!
What the diet guru says: According to David Zinczenko, author of The 8-hour Diet, eating all your meals within a set window is the key to burning fat. ‘By carving out an eight-hour window in which to eat to your heart's content, you'll burn your body's fat stores effortlessly. The science is actually simple: for several years, researchers have been producing remarkable weight loss results in people using "intermittent fasting". In this case, fasting is about eating whatever you want, but staying within a sensible eight-hour window. This gives your body the chance to burn away your fat stores for the energy it needs.’
The 2019 rankings include 41 of today’s most popular diets. New to the list this year is the Nordic Diet, a plant-heavy eating plan that incorporates Scandinavian traditions and ranked 9th best overall. Here’s how the rest of the rankings shook out this year, and what experts have to say about the good, the bad, and the trendy. (Here’s a hint: They’re still not crazy about keto.)
Also worth noting is that low-carbohydrate, low-GI, and Mediterranean diets led to significant improvements in blood lipids with up to a 4–10% increase in HDL (4% in the Mediterranean, 5% in low-GI, and 10% in low-carbohydrate diets), 1–4% reduction in LDL (1% in low-carbohydrate, 3% in low-GI, and 4% in Mediterranean diets), and 9% reduction in triglycerides. 
These affect your brain and spine, as well as the nerves that link them together. Epilepsy is one, but others may be helped by a ketogenic diet as well, including Alzheimer’s disease, Parkinson’s disease, and sleep disorders. Scientists aren’t sure why, but it may be that the ketones your body makes when it breaks down fat for energy help protect your brain cells from damage.

This diet also works for every type of eater who wants variety in their meals. I don’t know about you, but I’ve never had Pistachio-Crusted Sole much less would I know how to make it. But in the “Mediterranean Diet Plan,” everything I need to know is on page 175 along with substitution tips in case I can’t find pistachios or want to try pecans or cashews instead. I also can see the health breakdown too. “The Mediterranean diet incorporates as lot of nuts, like walnuts, pistachios, and cashews which have a lot of fiber,” adds Zogheib. “Also tuna fish, king mackerel, salmon, all have omega 3 and omega 6 fatty acids. There’s are whole grains, bananas, and one of the best oils to bake with — canola and olive oils. You can replace fatty butter with these oils when baking.”
