So for starters, don't worry about that occasional macadamia nut or avocado. Those are harmless in small quantities and certainly hasn't done anything to derail your efforts. They were still keto so you're good, and they were back out of your system in no time. That averages 5+ lbs per month, which is actually really good. Oftentimes we see a fast initial drop due to shedding water weight because you're depleting all your carbHYDRATE stores, and then it slows down to 1-2 lbs a week. Sometimes we hit plateaus where the scale doesn't move, but healing or body recomposition is taking place. Weight loss resumes after a while. You have to keep doing what you are doing. I would not call it a "stall" unless you haven't seen the scale budge in 3 months. In the meantime, let carnivore become your identity. This is your lifestyle now. You only eat animal products. What times do you eat? What time to you go to bed and wake up? And are you undereating? Intermittent fasting is a great idea. If I could, every day I would eat at noon and then again at 7pm. I go to bed at midnight (I am up past my bedtime tonight, lol). I try to make sure I don't eat within 4 hours of going to sleep, and that I don't eat immediately upon waking up (typically 7-8am). Sometimes circumstances are that I eat breakfast and dinner but skip lunch. I aim for around 2000-2500 calories, split between 2 meals. My thinking is to take the amount I would normally have eaten across 3 meals, and eat the same amount between 2 meals. In other words, these 2 meals are a little larger than before because I am taking half my 3rd meal and redistributing it to those other 2 meals. I am trying to avoid routinely undereating. It's okay to under eat or fast from time to time, but when you make it a habit, your body will adapt and slow down your metabolism because it thinks there's a shortage or famine. You can also test some things on yourself. For example, try eliminating the heavy cream (or any other dairy) for a week or two. Remember milk, by design, is intended to add bulk to a young calf. If you are using any kind of artificial sweetener, it could be triggering a cephalic phase insulin response. This happens to some people even with diet drinks, so avoid such diet drinks throughout the day and only have them with a meal (which is going to trigger an insulin response anyway). And then like Scott said, you can test different fat:protein ratios, and aim to get quality sleep. A lot of maintenance is done while you are asleep. And then when you wake up, go empty and weight yourself then as this will be the most accurate, before you start adding the weight of food and drink (and clothing).
Just that...lol I picked up a few apple fritters from my favorite place today for my mother and my aunt. It's a decent size grocery, but when I pulled in there were only 4 or 5 cars in a parking lot that usually has 20+? Funny thing was... as I followed an older couple down the aisle towards the donuts I see a young guy turn the corner with a box full. We continue, and the older couple goes straight to the donuts, which leaves me as first in line. I chuckled a bit as I thought 4 or 5 cars in the parking lot of this large grocery store, and 3 of the occupants of the 4 or 5 are here for donuts!
