I know easier said than done, but it is a key factor of the fat loss equation. Stress will ruin your insulin sensitivity causing the body to over secrete the fat storage hormone insulin. Furthermore high cortisol levels elevated due to stress also activate fat storage receptors, for men in the mid section and women have a harder time with the hips/buttocks area. We are well equipped to deal with short term stress such as being chased by a wild animal, but the long term stressors from over due bills, relationship issues, sick relatives etc are what really take a toll. Signs that you are overstressed include excessive body fat levels, consistent fatigue, irritability and lack of motivation. Overtraining syndrome has similar symptoms as high stress levels are one of the key factors involved with reducing your capacity to recover from training.
Listen to your mum - dieting is faddish. Instead, improve the "quite" to "all" healthy and eat only nutritionally balanced, healthy foods. Cut out all sweets and junk foods, apart from an occasional treat, as humans would have always done till recent times. The exercise is important, and include plenty of stealth exercise, such as taking the stairs instead of the elevator and cycling to the shops instead of driving, etc.
Basically, the effect of exercise on our weight is vastly overrated. That’s why it’s only number 15 on this list. There are other things you need to take care of first. It’s not a good idea to eat bad food, drink sugar water (so-called “sports drinks”) or be on medications which force you to exercise for hours daily just to compensate. Metaphorically that’s like digging a hole, into which you put your ladder, on which you stand and paint the basement-level windows of your house.
The meals shown here are "templates" that you can vary any number of ways to please your tastebuds and avoid eating the same old thing every day. Follow them and you'll get between 2,400 and 2,800 calories per day. That should provide plenty of calories for all but the most severely obese, while allowing most guys to lose fat around their middles at a steady pace. (Don't worry about hitting the numbers on the nose every time. If you exceed your fat quota during lunch, for instance, just cut back a little during dinner.)

Stop treating your kitchen like an all-night diner and you’ll stop seeing those unwanted pounds piling onto your frame, too. The results of a study published in Cell Metabolism found that mice who only had access to food during an eight-hour period stayed slim over the course of the study, while those who ate the same number of calories over a 16-hour period gained significantly more weight, particularly around their middle. When you’re finished with dinner at night, shut the fridge and don’t look back until morning — your belly will thank you. When you do head back to the kitchen in the A.M., make sure the 40 Things Healthy Cooks Always Have in Their Kitchen are there waiting for you. https://www.youtube.com/watch?v=97J5hzFjg3I

Weight training is the ultimate way to burn calories fast. "A pound of muscle burns up to nine times the calories of a pound of fat," explains Richard Cotton, M.A., chief exercise physiologist for myexerciseplan.com. Weight training increases your resting metabolic rate, which is the number of calories you burn while sitting on your butt. What's more, it gives your metabolism an added boost after you exercise, staying in overdrive for up to two hours after the last bench press, according to a study published in Medicine & Science in Sports & Exercise. Strapped for time? Try these quick moves: squats, bench step-ups, lunges, push-ups, pull-ups and planks. In a pinch, just do single sets of 10 for each exercise — you'll get optimal results for the time invested.
Avoid Junk Food – While you are at it, make sure that you do not eat junk food by any chance. By eating junk food, you are creating your chances of getting slim, very slim. Junk food like fries and burgers and flavored sodas are the worst enemy when you are aiming to lose weight. Instead of snacking on these, you must eat nuts, and fruits when feeling hungry. https://www.youtube.com/watch?v=TyXnVTALGM0
