Don’t want to log calories? Don’t want to track every little thing? Don’t really even want to change what you eat? Try a simple divided diet. I would suggest getting your TDEE from https://tdeecalculator.net/ and using that number. But, even if you don’t want to do that, just make up a number. Yep, make up a number and start from there. So, we’re going to start with 2000 calories a day. Lets say your target is 2000 calories a day. Just break that up in to 3/6/9/3. When you eat breakfast, eat no more than 300 calories. When you eat lunch, eat no more than 600 calories. When you eat dinner, eat no more than 900 calories. AND, I even threw in 3 – 100 calorie snacks for you. Still want cereal for breakfast? Just make sure it’s under 300 calories. Want a burger for lunch? Make sure it’s under 600 calories… and so on. Try something like this for a week and see how your progress goes after the week. If you gain, just drop each meal by 50 calories. Still gaining next week, drop it 50 more for each meal. Me personally, I’m around 200/400/600/200 for 1400 calories. This could be a pretty easy way to simply take a look at each meal and make sure THAT meal is on target, without keeping track of everything.
