The best diet for preventing heart disease is one that is full of fresh fruits, vegetables, and protein. Vegetables and fruits are good sources of vitamins and minerals and also low in calories and rich in dietary fiber and substances that may help prevent cardiovascular disease. Eating more fruits and vegetables may help you cut back on higher calorie foods, such as meat, cheese and snack foods.

There are other diets like Pale diet (includes fruits, vegetables, lean meats, fish, eggs, nuts and seeds and avoids processed foods, sugar, soft drinks, artificial sweeteners, trans fats, grains, most dairy products, and legumes), High-fat diet, and Keto/Ketogenic diet.

What is Keto diet?

The Ketogenic or “Keto” diet is a low-carbohydrate, protein and fat-rich eating plan gaining attention as a potential weight loss strategy. Research has shown a Ketogenic diet can induce rapid weight loss, partly from water loss but also some fat loss compared with a calorie-reduction diet. In our diet, 1000 to 1200 calories come from carbohydrates. When carb is taken out from Keto diet, then weight loss happens swiftly. 

While Keto supports a high-fat and low-carb diet, Paleo centers on meal plans based in whole and unprocessed foods. Although both diets avoid grains, beans, and sugars, there are distinct restrictions that each diet exclusively follows. If you banish carb and eat lots of fat and your body will start actually to burn fat and you will lose weight and even reduce your hunger in the process.

So exactly what foods can people eat on Keto diet?

People are supposed to get 5%of their calories from carbs, about 15% from protein, and 80% from fat.   

In general, our bodies are fueled primarily by glucose, which we get form carbohydrates. Pancreases secretes insulin, and insulin carries glucose to cell. However, when you are on Keto diet, you eliminate carbs and you start to eat lots of fat. In that case, instead of burning glucose for fuel, your body starts to burn fat. Because you have more fat but less carbs, when glycogen runs out, liver breaks fat down to ketones. To get into ketosis you need to eat less than 50 grams of carbs, or two slice of bread (carbs 21grams), of course eat lots of fat. Eat no carbs and the weight will come right off. There is some evidence in super-low-carb diets being effective in appetite control

What foods Keto diet includes?

In Keto diet, you get lots of fat and cholesterol, which is not good for heart. Nevertheless, some of the advantages of Keto diet cannot be denied. A high fat, low-carb diet can be an effective strategy for quick weight loss and blood sugar control because they cut off the juices, grains, and high calorie foods (chips, high sugar and bakery items) from the diet.

Although, Keto may be the latest in the fad diets, it had promising results since 1920s in the treatment of children who have difficulty in controlling epileptic seizures. Recently, outcomes from some research studies have showed its potential in treating subjects with type-2 diabetes. People have also found Keto diet beneficial in weight loss for decades with help of professional advice. As a diet for weight loss, it has been around there for a while. Keto diet will not help to burn body fat instead; it forces people to drastically reduce their sugar intake. Sugar is carbohydrate and it forces them to eliminate processed foods and junk foods. These are good habits for overall health.

In Keto diet, even if you choose all healthy fats, like olive oil and fish, you will still end up eating more saturated fat than is safe and healthy. Therefore, it is not good heart patients. Due to high fat diet, there are chances of increasing heart diseases and heart attacks. For the heart patients, the dietary hints include filling your plate with lots vegies, fruits, and some dals/legumes as opposed to highly processed meat and dairy products. Eating wisely key here.
