Welcome @Bokchoi A thing that I already had and used came into more use when I started keto…a cheap $12 digital scale will help you with accurate portion sizes to enter in the app. Now looking at the first days food menu I am not seeing a high carb count. I wonder if your app is set to count total carbs rather than net carbs.
This is important to remember; you can subtract listed dietary fiber from the total carb amount and what you have then is “Net Carbs”. It’s really simple. Just keep net carbs under 20. I don’t see 20 carbs in what you listed as your example. Eat low carb veggies for the bulk of your daily allowance. The rest are from small portions of high fat dairy, eggs and nuts if you’re eating those. You have to eat a lot of low carb vegetables to get 15 carbs so don’t stress about things like broccoli and cabbage. You would have to eat platefuls to go over.
Eat an adequate amount of protein for your lean body mass. Like 1gram per pound. It’s just a goal, if you’re a little over or under it’s ok. That’s not a food weight it’s the protein in the item you’re eating.
Fats are easy, just put some butter on stuff, Olive oil on salad or anything, cook with coconut oil and bacon grease or other animal fat of your choice. Don’t be stingy with fats. Cook a steak and pour the drippings on top. Cook mushrooms in the fats left in the pan. Eat an avocado regularly. Fats are easy to eat without carbs.
Sardines in olive oil, a one ounce serving of keto friendly nuts (no cashews, peanuts and watch it with pistachios) macadamias rule for fat content. Don’t overeat nuts. Cheese 1-2 ounces per day of hard aged cheese like cheddar, Parmesan whatever. Full fat dairy products, no low fat versions. Bacon, pepperoni, salami are okay.
Use your scale, learn to read labels.
Here’s a couple of useful things to help you with food choices
I hope some of this is helpful Bok Choi! Love the name.
