Weight not changing

TheImperfectMomma

So, every time I weigh myself (once a month at the beginning of the month), my weight doesn’t shift more than 0.5 lbs up or down. I’ve been working out 3-5 days per week alternating weights and cardio on different days. My tracking is pretty spot on for food minus the last couple weeks. I almost always come in under my calorie goal by 100 or more because I don’t eat until after I work so I generally only eat lunch and dinner and maybe a snack here and there.
I’m looking for slim down tips. I know the whole higher reps burn fat and lower reps build muscle. I don’t do any less than 12 reps per set and I do 4 sets for each individual workout. But pretty much all information is welcome! TIA!

If you aren't losing, then you're eating more than you think. You'll want to tighten up your logging, which may include any or all of the following: logging every single item you consume, using a food scale for all solids/measuring cups for all liquids, double-checking the accuracy of the entries you use against an item's nutrition label or the USDA database, utilizing the recipe builder over any "homemade" or "generic" items in the database, and being mindful of exercise calories burned/eaten back.

You might want to try weighing yourself every day for a week at the beginning of each month instead of just one day to get an average and avoid errors from fluctuations. If your weight is truly stagnant and you are doing the "right things" you might be building muscle, which isn't a bad thing at all.

Higher reps don't burn more fat than lower reps if you chose lighter weights. And weight training that doesn't get you to where you just about manage to do your reps is fairly useless. Or lets put it that way: I'm sure you can deadlift your bodyweight with a bit of training. 160lbs? If you do 10 reps with a 10lbs weight then you only shift 100lbs. That's less mass moved and less calories burned. Plus you probably use less muscles for that than for a complex lift.
