The South Beach Diet was created by a cardiologist in 2003, and it's considered to be a modified low-carbohydrate diet, according to U.S. News & World Report. It's based on the idea that carbs and fats can be either good or bad. If you decide to follow the South Beach Diet, you'll probably be getting fewer carbs and more protein and healthy fats than you're used to eating.
It also may help stave off chronic diseases, like heart disease and type 2 diabetes, as well as act protectively against certain cancers. (34) The diet is also a boon to mental health, as it’s associated with reduced odds of depression. (34) There’s even some data to suggest it can be supportive in relieving symptoms of arthritis, according to a paper published in April 2018 in the journal Frontiers in Psychology. (35)
Jan Engvald has studied food and health thoroughly in the literature. In Unexpected facts on... food he shows that today's health advice (more or less unchanged for more than 30 years) is a direct cause to the increase in national diseases like coronary heart disease, stroke, cancer, obesity, adult-onset diabetes, allergy, eye diseases, etc. His findings are low-carb and high-fat, close to paleo, though he allows high fat dairy.
Agatston believes that the faster sugar and starch are absorbed and the faster they enter the bloodstream, the fatter you will get. He suggests eating foods and combination of foods ( i.e., proteins, fat and small amounts of carbohydrates) that cause gradual rather than a sharp increase in blood sugar. Agatston makes distinction between good and bad carbohydrates. This is based on the glycemic index (GI). GI tells you how fast 50 grams of a particular food turns into sugar. Carbohydrates with a high GI raise blood sugar levels rapidly, while carbohydrates with low GI do it much slower. Examples of foods with high GI is white wheat bread, potatoes and various kinds of cereals. Green vegetables, whole grains, and beans are examples of foods with low GI.

The diet plan was initially developed for Agatston's own patients. Agatston noticed that the American Heart Association's then-recommended low-fat and high-carbohydrate diet was not lowering his patients' weight, cholesterol or blood sugar levels, but that his patients on the Atkins diet were experiencing weight loss. Unwilling to prescribe the Atkins approach to patients with cardiac issues due to the diet's allowance of saturated fat and limitation of carbohydrates containing fiber and other nutrients, Agatston referenced medical research to build an eating plan that categorized fats and carbohydrates as good or bad and emphasized lean protein and fiber.[17]
Followed this diet, lost 15 pound, back to my high school weight. My weekly migraines stopped. My 20 year back pain from herniated disk, tennis elbow and old motorcycle accident knee injury all stopped hurting. All I have to do is eat a pizza or sandwich if I want the pain back. Also I generally feel better and have more energy. It is not easy because pizza and chips an salsa and deli sandwiches all taste great, but it is worth it and not that hard to make the food amazing it about choices. Oh and I have three kids. One had ADD, another migraines and two bad acne, on this diet all cleared up. To get political for just a minute. If you read this and watch movies like Corn King, and In Defense of Food you will find that corn is a major source of the heath issues in our country, yet the government subsidizes the growing of corn, leading to 30% of American's being Diabetic or Pre Diabetic causing healthcare costs to sky rocket and now they what to fix health care, how about stop paying farmers to grow poison and direct them toward growing Paleo friendly foods. Try this for 6 months hard core and notice your ailment fade. Like I said, if i want a headache, I just need to eat a pizza or drink a beer. Oh one other thing, don't for the masses of "gluten free" junk food like cookies etc. These are just made of corn instead of wheat and are not paleo. Sorry but all cookies are junk food. Eat real food, you will be amazed.

In a review published this week in the new issue of Science, scientists from diverse backgrounds and research focuses came together to address whether a high-fat, low-carbohydrate diet or vice versa was the better option for maintaining good health, as well as whether the specific kinds of fat and carbs mattered. The researchers—from the Harvard T. H. Chan School of Public Health, Boston Children’s Hospital, Ohio State University, and others—hoped that by comparing their knowledge of nutrition, they could both find general areas of agreement and identify others where more research is needed in an effort to the end the so-called “diet wars.”
As Agatston outlines in his book, the long-term effects of following the South Beach Diet — beyond just losing weight — include lowering your cholesterol, along with your risk of heart attack, stroke, diabetes, and even some cancers. Those are long-term effects that most diets don’t offer simply because they aren’t set up for you to stick with them indefinitely.
Exercise is a vital part of the live-by-your-genetic-code equation. Surviving in the Stone Age meant a constant on-the-go lifestyle that probably required 4,000-plus calories a day, according to David L. Katz, MD, director of the Yale University Prevention Research Center. Even most people who hit the gym regularly won't need to eat that many calories, but the principle of using food as fuel to exercise still stands.
Advocates of the diet argue that the increase in diseases of affluence after the dawn of agriculture was caused by changes in diet, but others have countered that it may be that pre-agricultural hunter-gatherers did not suffer from the diseases of affluence because they did not live long enough to develop them.[30] Based on the data from hunter-gatherer populations still in existence, it is estimated that at age 15, life expectancy was an additional 39 years, for a total age of 54.[31] At age 45, it is estimated that average life expectancy was an additional 19 years, for a total age of 64 years.[32][33] That is to say, in such societies, most deaths occurred in childhood or young adulthood; thus, the population of elderly – and the prevalence of diseases of affluence – was much reduced. Excessive food energy intake relative to energy expended, rather than the consumption of specific foods, is more likely to underlie the diseases of affluence. "The health concerns of the industrial world, where calorie-packed foods are readily available, stem not from deviations from a specific diet but from an imbalance between the energy humans consume and the energy humans spend."[34]

If you have diabetes, you should focus on eating lean protein, high-fiber, less processed carbs, fruits, and vegetables, low-fat dairy, and healthy vegetable-based fats such as avocado, nuts, canola oil, or olive oil. You should also manage your carbohydrate intake. Have your doctor or dietitian provide you with a target carb number for meals and snacks. Generally, women should aim for about 45 grams of carb per meal while men should aim for 60. Ideally, these would come from complex carbs, fruits, and vegetables.
Generally a good source of fiber, vitamin C and antioxidants, fresh fruit is a healthy way to indulge your sweet tooth. If it helps you to eat more, add a little sugar—drizzle slices of pear with honey or sprinkle a little brown sugar on grapefruit. Keep fresh fruit visible at home and keep a piece or two at work so you have a healthful snack when your stomach starts growling. Lots of grocery stores stock exotic fruit—pick a new one to try each week and expand your fruit horizons.
One review, published in April 2016 in The American Journal of Medicine, looked at five research trials on overweight and obese people and found that after one year those who followed a Mediterranean diet lost as much as 11 pounds (lbs) more than low-fat eaters. (6) (They lost between 9 and 22 lbs total and kept it off for a year.) But that same study found similar weight loss in other diets, like low-carb diets and the American Diabetes Association diet. The results suggest, the researchers say, that “there is no ideal diet for achieving sustained weight loss in overweight or obese individuals.”
A vegetarian eating pattern is based on plant foods, such as vegetables, fruit, whole grains, nuts, seeds, beans and meat substitutes with little or no animal products. The vegetarian diet is rich in vitamins, minerals and fiber, and lower in saturated fat and cholesterol. There are several types of vegetarian eating patterns, and they vary in terms of what is included:
Although South Beach's most restrictive phase lasts only two weeks, even phase two calls for avoiding (or strongly limiting) foods like bagels, white bread, potatoes, cookies, ice cream, honey and jam. Same goes for pineapple, watermelon and raisins, permitted only once in a while. (These fruits are high in sugar.) You may need to muster up willpower to stick to the program.
There is no good evidence that low-carbohydrate dieting is helpful in the management of type 1 diabetes, and only weak evidence that carbohydrate reduction in an otherwise healthy diet is helpful in managing type 2 diabetes.[20][4] In persons with diabetes mellitus Type 2, a low-carbohydrate diet gives slightly better control of glucose metabolism than a low-fat diet.[21][22] Limiting carbohydrate consumption is a traditional treatment for diabetes – indeed, it was the only effective treatment before the development of insulin therapy – and when carefully adhered to, it generally results in improved glucose control, usually without long-term weight loss.[23][16]
For most people with type 2 diabetes, the general guideline for moderate alcohol consumption applies. Research shows that one drink per day for women and two a day for men reduces cardiovascular risk and doesn't have a negative impact on diabetes. However, alcohol can lower blood sugar, and people with type 2 diabetes who are prone to hypoglycemia (such as those using insulin) should be aware of delayed hypoglycemia.

Knowing what to eat is part of it, but following this fairly restrictive lifestyle in a modern environment surrounded by cookies and candy and bagels and pasta is really difficult! Factor in the “carb flu” you might go through in the first few weeks (as your body gets weaned off of carbohydrate fuel and habits), and most people give up on the Paleo diet long before it creates lasting change!
In the short term, you may lose a modest amount of weight over a year span and are likely to keep it off it you continue to eat following the diet. (6) If eating in the Mediterranean style prompts you to consume more fruits and vegetables, you’ll not only feel better physically, but your mental health will get a lift, too. Research shows that people who eat more raw fruits and veggies (particularly dark leafy greens like spinach, fresh berries, and cucumber) have fewer symptoms of depression, a better mood, and more life satisfaction. (36)
Fat isn’t unlimited either. As with wine, it's possible to get too much of a good thing when it comes to healthy fats. The American Heart Association points out that while the Mediterranean diet meets heart-healthy diet limits for saturated fat, your total fat consumption could be greater than the daily recommended amount if you aren't careful. That’s 65 g per day. (32)
You mentioned ketone strips. If they are the urine strips they are useful to see if you are in ketosis, fat burning mode, but be aware they are not completely accurate but are a good guide to how you are doing. The blood strips are way too expensive but more accurate. I have a blood glucose monitor and went through a phase of testing to see how I react to dairy, protein, cream, coffee etc. I rarely do it now as I want this way of eating to be as simple as possible, but again, a useful tool starting out.
Grains and legumes (or pulses) are other groups that are frowned upon in the diet. "The right grains in the right amount can actually curtail inflammation," says Bonnie Taub-Dix, MA, RD, CDN, creator of the blog Better Than Dieting and author of Read It Before You Eat It: Taking You From Label To Table. In addition, fiber-rich legumes, including beans, lentils, and peas, have been consistently linked with reduced risk of obesity and chronic disease. "Fiber-rich carbs can supply energy, fiber, a host of vitamins and minerals, and a soothing satisfaction that could keep us from eating less nutritionally dense choices," Taub-Dix says. With the rise in popularity of ancient grains such as amaranth, millet, oats, and teff, and pulses, such as chickpeas and lentils, there's much opportunity to access versatile, naturally delicious whole grains and legumes that our ancestors ate. "Carbohydrates have a bad reputation, justified by the company they often keep, such as rich sauces and butter, and the forms in which they may be served (eg, donuts and pastries)," Taub-Dix says, "but the right carbs can save us from degenerative diseases."
In 2008, Agatston published The South Beach Diet Supercharged, written with Joseph Signorile, a professor of exercise physiology; it included an interval training program.[21] A review for the Academy of Nutrition and Dietetics found that "Readers are likely to see success using this diet and fitness book. I recommend skipping the restrictive Phase One meal plans and instead follow the more balanced Phase Two diet. The simple 20-minute-a-day exercise program is a realistic and inexpensive approach to fitness."[21]
No clear proof exists that taking dietary supplements such as vitamins, minerals, herbs, or spices can help manage diabetes.1 You may need supplements if you cannot get enough vitamins and minerals from foods. Talk with your health care provider before you take any dietary supplement since some can cause side effects or affect how your medicines work.2
