How low are your carbs? You mention fruit so I’m assuming things like berries? I won’t tell anybody to not eat fruit or nuts but if you are committed to Keto that’s where I would start.
The message board itself freaked out (not the posters but the actual board) and went a little crazy there for a while. Typically this is what I have been eating . . .
Breakfast: A yogurt with 2 strawberries or 5-6 blackberries and a hard boiled egg. Once in a while bacon and eggs instead.
Lunch: Basically a salad with dark greens, spinach, kale, and some olive oil but blended together in water so a green smoothie and a small container of guacamole. Once in a while something like a chicken salad salad or a tuna salad salad.
Afternoon snack: A handful of mixed nuts, a handful of blueberries, or a couple of spoons of peanut butter.
Dinner: Whatever the protein of the day is (fish, shrimp, chicken, steak, pork), a side salad, and a vegetable (broccoli or green beans).
Mostly nothing but water to drink (probably 8 bottles a day). No breads, no pastas, no potatoes, no chips, no sweets, no soda, no coffee, no deserts, nothing high in sugar.
Have been going on walks before work and at night. Sometimes at lunch time instead. Minimum of 10,000 steps a day. Since I had COVID, I don't sleep through the night, so I generally start at 5:00 AM and go through 10 PM . . . meaning I am around and active for way more hours than ever before.
When I did keto in the past, there were times I wasn't hungry at all and could fast and go from breakfast one day to dinner the next day no problem. The issue I have now is I haven't been able to skip a meal because I am always hungry.
