I’ve been there and have tried the Ketogenic Diet. It’s very difficult even though I am a very determined and goal oriented person. When I set my mind up to do something, I will normally achieve it because I am just so stubborn about personal goals that I don’t give up until I do! Yes, you will lose a lot of weight quickly, but I am not interested in giving up bread, pasta and birthday cake for the rest of my life.
DASH is based on the following foods: fruits, vegetables, low fat milk, whole grains, fish, poultry, beans, and nuts. It recommends reducing sodium, foods and beverages with added sugars, and red meat. The diet is heart-friendly as it limits saturated and trans fat, while increasing the intake of potassium, magnesium, calcium, protein, and fiber, nutrients believed to help control blood pressure. 
The problem is: it flies in the face of the way we have been taught. Our society (as an American), and our medical community, have preached for years that FAT is bad, and you should limit it. However, recent FACTS beg to differ. So many people rail against the keto diet because they just feel that it can’t be good…after all, you eat so much fat on it, it can’t be good for you! Facts are facts…they don’t care about your feelings. Fat is not the enemy. Sugar is.
The keto diet is NOT what you seem to picture. I laughed at your description as I was eating lamb chops, cauliflower rice, broccoli, followed by cheesecake. How deprived I was! You should relook at what the diet really is. By the way, my cardiologist highly recommends keto. Most people see a drastic decrease in their triglyceride/HDL ratio. Looking at total cholesterol or LDL alone is 20 years out of date! Even the AHA has caught up, and now says that it’s NOT how heart health should be judged.
In this single-arm, 4-month diet intervention, an LCKD resulted in significant improvement of glycemia, as measured by fasting glucose and hemoglobin A1c, in patients with type 2 diabetes. More importantly, this improvement was observed while diabetes medications were reduced or discontinued in 17 of the 21 participants, and were not changed in the remaining 4 participants. Participants also experienced reductions in body weight, waist circumference, and percent body fat but these improvements were moderate and did not predict the change in hemoglobin A1c in regression analyses.
Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.
