Each meal you have to judge how much fat you need. If you’re really battling a high appetite/high craving day or week, you might want to add more fat, especially at breakfast to trim your appetite throughout the day and enable you to go longer without cravings and hunger. Ketosis in general suppresses your appetite, so your hunger will be greatly reduced. You're going to be able to go many hours without eating. So let the hunger dictate how much fat you eat. If you're not hungry, cut down on the fat and go a little bit lighter. You might need a little bit more fat sometimes, but don't go crazy, because that's going to slow you down.
In short, no. Apples even have too many carbs. Pineapples hugely spike insulin. Never consume fruit juices. The fiber is bound to the phytonutrients and the juice is cooked, removing many nutrients. You’re basically just drinking concentrated fructose + corn syrup. As an adult, I wouldn’t consume much fruit, period—except maybe ½ cup berries a day. Fructose consumption can lead to a fatty liver, insulin resistance and can spike insulin MORE THAN GLUCOSE!
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.
That’s why many health experts are concerned about people on the keto diet, especially those who try it without the guidance of a doctor or nutritionist. Doctors say that high-fat diets like this one may raise cholesterol levels, and some studies suggest that they increase the risk of diabetes. Some have even called it a “cardiologist’s nightmare.”
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.
