And there lies the problem. People get too obsessed with calorie counting that they forget how the body works. Build muscle and just workout regularly. Never stop. Lift weights. Muscles do burn more calories. In the end, you will end up weighing more but actually looking leaner as you have changed your body composition.
Use high intensity interval training principles whenever you work out - studies have shown that HIIT increases your resting metabolic rate for hours afterwards (also known as the afterburn effect).
Use every spare second you have to be active - do a short mini workout oike Grind Hard or take a quick walk or just do pushups/situps/crunches etc. All these increase you daily total calorie use and boost your metabolism.
I'm taking medications for my hypothyroidism but that's another story. As what they've said, do a daily workout to build muscles as they help in our metabolism.
