I am currently 18.6 stone. I started dieting three days ago and have massively reduced my caloric intake. For example, last night I had only 200 calories after subtracting my cardio, according to my calorie tracker (My Fitness Pal). Normally I would be over the daily guidance amount, but does this really make a difference? I read that the ONLY way to lose weight is to burn more calories than you consume. So even though I cut off hundreds of calories from my diet, I still won't be losing weight as a result of it? Or am I understanding this wrong?
On a related topic, Subway is advertised as having healthy options. Is it possible to eat a meal there that would support my weight-loss goals?
