Warm for about 45 seconds on each side.
Cut back on calories. The most important part of losing weight is not working out until you collapse — it's your diet. If you burn 500 to 750 more calories than what you eat every day, you will lose 1–2 pounds every week (any more than that is considered unsafe weight loss). There are tons of little changes you can make to cut calories from your diet, from replacing high-calorie dressings with vinaigrette and asking for all dressings/sauces served on the side, eating at the table instead of in front of the tv, skipping cheese and other fatty additions to your salads and meals, using smaller plates, leave off the whipped cream on your coffee drink, and on and on.[2]

Day 6 is a little different to day 5. You will be eating sprouts, cottage cheese and other vegetables but by excluding tomatoes. No tomatoes on day 6, avoid them.  The tasty soup and lots of water should help you through your day. Vegetables will provide vitamins and fibre to your body. You will already notice change in your body by this time. Continue consuming a good amount of water everyday.

Eat at least 1g of protein per pound of bodyweight, daily. If your protein intake is too low on a restricted-calorie diet, you'll lose a lot of muscle in addition to any fat you're lucky enough to shed. A high-protein intake will help you preserve lean mass during your dieting phase. Choose lean, high-quality proteins like egg whites, poultry, lean red meat, and protein supplements. The diet provided here contains about 220-250g of protein daily, fine for a male weighing 200-250lbs. Up your protein only if you're heavier than 250lbs, or you're very hungry and need to add food during the day. Juge suggests an additional protein shake for an easy quick fix. (If you're under 180lbs, cut out 3oz of meat or chicken per day from the diet.)
Eating can become just as disorganized and chaotic as any other activity that isn't thought out ahead of time. Planning establishes structure, which can help you stay within a calorie budget, reduce daily decision-making, and prevent overeating. Carve out some time today to think through a plan for the week. Start with a few basic foods to eat each day and add others to diversify your meals. Make a grocery list as you go. (Make it even easier! Cook quick meals at home that taste great and fight fat! Sign up for Chef'd and get all the ingredients and recipes delivered to your doorstep.) 
Think of it like this: What words come to mind when you picture a movie theater? Popcorn? That's because you've linked the movie theater with eating popcorn. Eating to satisfy hunger is an appropriate reason to eat, while eating just because you're in a movie theater (or a room in your house) is not. These habits can seriously derail your weight loss efforts.
Other workouts such as full body resistance training workouts are a great way to reduce the carb storage and water weight in your body. This will help your efforts of how to lose weight quicker. Weight lifting also has certain advantages such as protecting your metabolism and hormone levels which often tend to decline while you're on a diet. High Intensity Interval Training has also proved to be a very effective method to help lose weight fast.
Have a small, protein-heavy breakfast. Kickstart your day with a protein filled breakfast that will give you energy (and keep your blood sugar up) for the rest of the day. Aim for a breakfast that is 400 calories and eat it every morning at around the same time. Go for variety and rotate two to three options. Pair your breakfast with unsweetened tea or a glass of water with lemon.[6]
