Drink sugar water once a day. This brain hack works by suppressing production of the hunger hormone ghrelin and is a small exception to the no sugar rule above. It was discovered by the late Dr. Seth Roberts, and tested and verified by Drs. Stephen Dubner and Steven Levitt, of Freakonomics fame. Done properly, it has a dramatic appetite-suppressant effect, making your diet much easier to follow.
Frequent and sustained cardio training is one of the best ways to burn fat and boost metabolism. One of the best cardio exercises to perform is running, according to the American College of Sports Medicine, as it burns a high number of calories per hour and improves cardiovascular health. ACSM recommends training five days a week, with a minimum of 60 minutes per session.
For those of you who aren't familiar with HIIT, it involves intervals of high-intensity exercise (such as running at 90% of your max heart rate) followed by low intensity (walking at a moderate pace) or complete rest. This is in sharp contrast to the typical steady-state cardio most people do at a moderate intensity, such as walking on a treadmill at 60-70% of their max heart rate.

Trim Portions. If you did nothing else but reduce your portions by 10%-20%, you would lose weight. Most of the portions served both in restaurants and at home are bigger than you need. Pull out the measuring cups to get a handle on your usual portion sizes, and work on paring them down. Get instant portion control by using small bowls, plates, and cups, says Brian Wansink, PhD, author of Mindless Eating. You won't feel deprived because the food will look plentiful on dainty dishware.
"Feeling stressed can wreak havoc on our bodies. It can cause our body to produce the steroid hormone cortisol, which can make you crave sugary foods that provide instant energy and pleasure. Short-term bursts of cortisol are necessary to help us cope with immediate danger, but our body will also release this hormone if we’re feeling stressed or anxious. When our cortisol levels are high for a long amount of time, it can increase the amount of fat you hold in your belly."
