Similar to Greek yogurt, research has shown eating eggs for breakfast can make you feel more full and help you eat fewer calories throughout the day, meaning they’re quite the secret weapon for weight loss. Nutritionally speaking, one large hard-boiled egg (about 50 grams) contains less than one gram of carbs and remains an excellent source of protein. Eggs are also loaded with amino acids, antioxidants, and healthy fats.

Eating low-carb paleo means removing items like rice, pasta, and legumes from your diet completely, but the carbs you eat will be from vegetables like fruit, beets, sweet potatoes, and leafy greens, such as spinach and kale. The diet also cuts out processed food plus foods allowed on other low-carb diets, including milk and cheese, and some people have an easier time sticking with the diet when more carbs are included.
In the mid-1990s, Hollywood producer Jim Abrahams, whose son's severe epilepsy was effectively controlled by the diet, created the Charlie Foundation to promote it. Publicity included an appearance on NBC's Dateline programme and ...First Do No Harm (1997), a made-for-television film starring Meryl Streep. The foundation sponsored a multicentre research study, the results of which—announced in 1996—marked the beginning of renewed scientific interest in the diet.[1]

The herbs and spices associated with the Mediterranean diet shine at dinner. Meal options include fish like grilled salmon or pan-seared trout, seasoned with lemon and dill; chicken baked with a little olive oil and rosemary; grilled lamb chops with mint; mussels cooked in a tomato, garlic and wine broth; chili made with ground turkey, kidney beans and cayenne, or vegetarian-style with a mix of beans; and scallops sauteed with mushrooms and leeks. Have a 4-ounce serving of protein, and fill the rest of your plate with cooked veggies, like cauliflower, broccoli, brussels sprouts, or green beans.

U.S. News’s Best Diets rankings are put together by a panel of nutritionists, dietary consultants, and doctors specializing in diabetes, heart health, and weight loss. Each member of the panel scored all 41 diets in seven different areas, including how easy they are to follow, how well they protect against chronic disease, and how likely it is that followers will actually lose weight and keep it off.
The risks are more long term, such as risk of nutritional deficiency (vitamin c, a, k and b vitamins) and also increased risk of bowel and possibly breast cancer cancer due to limited fibre intake. Ketosis generally isn’t recommended and it’s not exactly a state that would the body would usually be in, but it can be done safely for set periods of time.’
What the diet advocate says: 'The key components of a Mediterranean diet are lots of vegetables, olive oil, oily fish and nuts, with no calorie restrictions. Combine that with cutting down on sugar, which was traditionally a rarity in the region, and you’ve got the base of the Mediterranean diet right. And if you get the base right you can eat a little of whatever else you like,' says Consultant Cardiologist Dr Aseem Malhotra.
On day 1, have a cup of plain low-fat Greek yogurt for breakfast, topped with 1/2 cup of blueberries and an ounce of chopped walnuts. The yogurt gives you calcium and satisfying protein, while the berries are full of antioxidants that protect you against cellular damage, and the nuts supply heart-healthy omega-3 fats. Have yogurt on day 4, too, but try pomegranate seeds and chopped pistachios -- or sliced oranges and chopped almonds.
Many diet plans cut out entire food groups, which can create nutrient deficiencies as well as health problems. For instance, if the diet is very low in carbohydrates and you have type 1 diabetes or type 2 diabetes, it’s probably not a good fit. And if it’s too restrictive and you’re pregnant or breastfeeding, it’s not a good idea, either. Keep in mind that pregnancy is not a time for weight loss. Speak with your doctor before making any changes to your diet if you are pregnant or breast-feeding.

What the diet advocate says: ‘It essentially means scaling your carbohydrate intake up and down in accordance with your activity levels,’ explains performance nutritionist Liam Holmes (phnutrition.co.uk). He uses the principles of nutrient timing to get elite athletes and CrossFit enthusiasts to their leanest before competitions. ‘The body works harder when it doesn’t have carbs as fuel, so it learns to become a more efficient burner of the fuel once it is there.’
The classic ketogenic diet is not a balanced diet and only contains tiny portions of fresh fruit and vegetables, fortified cereals and calcium-rich foods. In particular, the B vitamins, calcium and vitamin D must be artificially supplemented. This is achieved by taking two sugar-free supplements designed for the patient's age: a multivitamin with minerals and calcium with vitamin D.[3] A typical day of food for a child on a 4:1 ratio, 1,500 kcal (6,300 kJ) ketogenic diet comprises:[27]
Con: Results can vary depending on how much fluid you drink. By drinking more water, you dilute the concentration of ketones in the urine and thus a lower level of ketones will be detected on the strips. The strips don’t show a precise ketone level. Finally, and most importantly, as you become increasingly keto-adapted and your body reabsorbs ketones from the urine, urine strips may become unreliable, even if you’re in ketosis.
