Never attempt to train yourself into a caloric deficit. Don’t spend hours on the treadmill. Diet comes first, cardio second. The dumbest fat loss strategy ever devised is used by people that wake up early in the morning before going to work to do cardio and follow that up with a “recovery shake.” Congratulations, you just wasted two hours of your life. Cardio is good for cardiovascular health, but most people use cardio as a fat loss tool - and force themselves through regimens that aren’t very conducive to their daily routine (or mental sanity). Next time, skip the shake and the cardio. Sleep two hours longer, but skip breakfast and fast until lunch time. This way you can create the same caloric deficit with the added bonus of feeling more rested and having saved more time. You’ll be much better off.
