I’ve been trying this keto diet that my dr.and daughter recommended, it’s been close to a week. I’ve changed my food intake, no bad carbs that I know of, was a huge chip addict stopped all that with no cravings. I’m not seeing any results I’m getting discouraged and everything sounds so complicated watching this, measuring that, I don’t have a clue what I’m doing. just that I stopped bread,pasta,poratoes,rice all those kind of carbs.I’m drinking more water eating green vegetables and trying to increase my fat intake. I don’t feel motivated to exercise which probably doesn’t help and have 100-130 to lose. I need help I don’t understand or have the time create a lot of meals and measure my fat,protein and carb intake.
You eat a ton of good fats on keto, and fat is satiating, helping you you feel full for longer.[7] Fat also keeps your blood sugar stable, so you don’t experience energy highs and lows. When your body runs on ketones for fuel, it has a steady supply of energy in the form of body fat. When your body relies on glucose, it needs a regular hit of carbs to keep it going. Think of how you feel after eating a white bread sandwich and kettle chips for lunch. You’re ready to raid the fridge a couple of hours later. When you instead eat some grass-fed steak with butter-drenched steamed vegetables, you’ll power through your afternoon minus any distracting cravings.   
Weight loss often means feeling hungrier and fighting off more cravings, but that doesn’t always seem to be the case when you go keto. People report less hunger and a diminished desire to eat after adopting a ketogenic diet, according to an analysis of 26 studies. Experts don’t fully understand why, but it’s thought that very low carb diets could suppress the production of hunger hormones like ghrelin.

Most low-carb diet authors don't recommend bothering with it. Even many of those who think a ketogenic diet is a good thing just assume that a very-low-carbohydrate diet (under about 50 net grams of carbohydrate) is ketogenic. On the other hand, many people have found that monitoring their ketones, at least for a while, provides valuable information.
I have great respect for Harvard Medical School. I notice that they support their readers posting comments and I am most appreciative of the article and all the many thoughtful comments by the readers. The readers seem to have the most expertise here and I hope that the doctor who wrote the article will think long and hard about the comments by readers. After 35 years of clinical practice in mental health, I notice that all issues of emotion involve medical issues, nutrition, and the gut bacteria. I would say that these issues and all of the executive brain functions seem to improve with ketogenic principles. For those that apply it in a flexible and smart manner, it appears to improve every area of their lives. I strongly encourage the author of the article to take one class via The Institute for Functional Medicine. If he is open to more learning he can take more classes and get certified. I’m sure a fine doctor, he will be an even better doctor and personally healthier, if he gets more training. Are we all open to new learning(especially us healthcare providers)?
If you think about it, one of the diets that follow these principles is the low-carb ketogenic diet. It focuses on highly-satiating foods like meat and low-carb vegetables while cutting out all processed, carb-ridden, and highly-palatable foods. By eating in this way, most people experience tremendous amounts of fat loss — not because insulin levels dropped or the body got a metabolic advantage from burning fat, but because keto dieters tend to eat significantly fewer calories than before without realizing it.
Certain studies suggest that keto diets may “starve” cancer cells. A highly processed, pro-inflammatory, low-nutrient foods can feed cancer cells causing them to proliferate. What’s the connection between high-sugar consumption and cancer? The regular cells found in our bodies are able to use fat for energy, but it’s believed that cancer cells cannot metabolically shift to use fat rather than glucose.

Taken together, these results demonstrate a positive effect of LCD/KD on body composition. While KD may not be superior to other dietary strategies aimed at weight reduction, the evidence does suggest that it may be equally effective. Nevertheless, the International Society of Sports Nutritionists, in their Position Stand on the effects of diets on body composition, suggest the KD holds little benefit over higher CHO diets, with one notable exception; KD may enhance appetite control (1).

Food reward regions in the brain programmed much of this physical dependence on processed foods and refined starches. But the body can reverse it. Acute bouts of aerobic exercise have been shown to significantly suppress appetite and hunger while increasing satiety and fullness.6 Exercise in the form of resistance (weight) training can enhance insulin sensitivity,7 which results in reduced insulin secretion.8 Less insulin helps bodies favor fat burning over fat storage.
“As a reproductive endocrinologist, I have been studying nutrition and fertility for over 15 years. I advise all my patients, both women and men, to adopt a low-carb ketogenic diet both prior to pregnancy to improve their fertility and during pregnancy to improve fetal and maternal health. This way of eating has been shown repeatedly in my practice to improve all measures of health for women and men. We refer all our patients to Diet Doctor which in our opinion is the best online resource for our patients to find all the information, recipes and meal plans they need to be successful.”

The Bulletproof Diet (download the roadmap for free here) counters these side effects by keeping protein levels even lower. It is a cyclical ketogenic diet, which means you eat keto for 5-6 days a week and then do a weekly protein fast, which lowers inflammation and kickstarts fat-burning. This is much better for your body and spurs weight loss even more. The Bulletproof Diet also involves a carb re-feed day, where you eat slightly more carbs than usual. Since keto diets mimic starvation, you want to make sure your body knows that food isn’t scarce (this is especially important for women trying to conceive).
