But the real reason why keto plans fail most of us is that they're not sustainable for the long term. Holidays, vacations, work functions … there's likely at least one scenario in which you'll find yourself eating higher-carb foods. And the same reasons why we see immediate weight loss on carb-restricted diets is the same reason why we see immediate weight gain after adding a seemingly harmless sandwich back into the mix: The water weight comes back instantly with glycogen storage.

But when you look at long-term results, there is very little difference between the two. 'Part of this is because adherence is very poor for low-carb diets in the long term – that is, people find it difficult to maintain a very low-carb diet, which suggests it's probably not sustainable to continue eating this way in the long-term,' says Dr Barclay.
It is possible to combine the results of several small studies to produce evidence that is stronger than that available from each study alone—a statistical method known as meta-analysis. One of four such analyses, conducted in 2006, looked at 19 studies on a total of 1,084 patients.[22] It concluded that a third achieved an excellent reduction in seizure frequency and half the patients achieved a good reduction.[3]

Eggs are a healthy, nutrient-dense food that has been incorrectly maligned for years. Cholesterol in food doesn’t increase cholesterol in your blood, so eat eggs liberally – they’re packed with protein and lutein, and they fill you up for hours. Make a healthy omelet with some cheddar, crumbled breakfast sausage, and shredded spinach and you’re already looking at over 30g of protein, just for breakfast! Spinach is a great source of magnesium and potassium, too. Add some sea salt and you’ve got a big dose of electrolytes that are so vital to maintaining energy and staving off headaches.

Fears about fat: Most people have trouble on a ketogenic diet plan because they are scared to increase the amount of fat they eat, especially saturated fat. The message that fat is bad has been pounded into the collective American consciousness for the last 30 years. It's hard to unlearn the message that fat makes you fat, and saturated fat especially is very bad for you. I understand that message has been repeated over and over, but it is a lie. 

While macros will differ a little from person to person, the general rule of thumb for keto is to keep carbohydrates under 5% of your daily caloric intake. As long as you avoid the foods mentioned above, you should be fine. Google “TDEE calculator” if you need some additional guidance on how many calories to eat. I’ve had success following this way of eating as it allows me to eat foods that taste great. There are tons of resources online as well if you need additional guidance. A quick google search should turn up a ton of resources. Hope this helps!
It is not necessary to be as strict with children as you would be for yourself. Children are generally more insulin sensitive than adults, which means their bodies can deal with sugars and carbs more efficiently. Focus on whole foods, good sources of protein, lots of good fats (essential for brain development), and getting carbs from nutrient-dense sources.
A keto diet has shown to improve triglyceride levels and cholesterol levels most associated with arterial buildup. More specifically low-carb, high-fat diets show a dramatic increase in HDL and decrease in LDL particle concentration compared to low-fat diets.3A study in the long-term effects of a ketogenic diet shows a significant reduction in cholesterol levels, body weight, and blood glucose.
