"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."
Jame LeCheminant and colleagues looked at the short-term effect restriction of night eating had on daily calorie consumption, weight trends, and even mood associated with this deprivation. They recruited 29 young men and asked them to avoid consuming calories (water was okay) between the hours of 7 p.m. to 6 a.m. for two weeks. During these two weeks the participants recorded every bite they consumed, and their weight, mood, and level of hunger at breakfast were monitored. There was a one-week break, and then for two more weeks (a control period) the subjects were monitored as they returned to their usual way of life. That’s it. There were no other interventions or exercises to perform.
People often think that low-intensity exercise, in which your body taps into fat metabolism, is the most efficient way to lose body fat. Some cardio machine displays even claim that you’re in the fat-burning zone when your heart rate is low and that you exit the zone once your heart rate rises. Physiologically, the second part of that statement isn't true. 
Since growth hormone is a potent fat burning hormone this will further increase fat burning in the post exercise state. Short duration sessions simply preserve muscle tissue far better than long drawn out cardio sessions. Compare the difference in physiques between a sprinter and a marathon runner. They are both runners but they have drastically different looks to their bodies.
Sure, you can lose weight quickly. There are plenty of fad diets that work to shed pounds rapidly -- while leaving you feeling hungry and deprived. But what good is losing weight only to regain it? To keep pounds off permanently, it's best to lose weight slowly. And many experts say you can do that without going on a "diet." Instead, the key is making simple tweaks to your lifestyle.
It depends on just how many potatoes we're talking here! One medium potato has around 37 grams of carbs, so if you limit your carb count elsewhere, this is no problem. What you really have to watch out for are the toppings, like butter, cheese, sour cream, bacon, and rich sauces like gravy. Do some math to figure out how to balance the carbs from your potato and toppings with the other foods you eat.
Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue. Weight loss can either occur unintentionally due to malnourishment or an underlying disease or arise from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition. Intentional weight loss is commonly referred to as slimming.
Do more HIIT: High intensity interval training (HIIT) is as close to a magic pill as we have (except it involves a whole lot more work than just swallowing a capsule—sorry). Not only does it surge your body to max intensity during the workout, but because you’re working so hard, your body can’t deliver enough oxygen in the moment, explains personal trainer Jeremey DuVall. Your muscles accumulate a “debt” of oxygen that then has to be repaid post-workout. This throws your body into a phase of fat burning for hours after you’re done sweating, known as post-exercise oxygen consumption, or EPOC. Plus, super intense circuits like this activate muscle-building hormones like growth hormone and IGF-1, he adds.
