Do aerobic exercises daily. Sure, you can do 100 crunches a day, but if you've got a layer of belly fat covering up your ab work then what's the point? You need to burn the top layer of stomach fat to see the changes. Cardio exercises will heat up your core temperature and improve circulation, both of which will aid in acquiring a flat stomach. Strive for at least 30 minutes a day minimum, but include 1-2 days of rest each week.
Simply exercising on your stationary bike for hours is not enough. Long, slow cardio sessions are not the ideal work out for a slimmer waist. Doing crunches until you can’t stand up straight is also not enough to have a slim waist.  Ab-focused exercises like the popular crunch isolate the abs but fail to hit the muscles that run up your side (the obliques) and the deep, ‘corset’ muscles of the abdomen (the transversus abdominis or TVA).
The Mayo Clinic Diet provides practical and realistic ideas for including more physical activity and exercise throughout your day — as well as finding a plan that works for you. The diet recommends getting at least 30 minutes of exercise every day and even more exercise for further health benefits and weight loss. The diet also emphasizes moving more throughout the day, such as taking the stairs instead of an elevator. Best Yoga Poses for Weight Loss & Flat Stomach | Swami Ramdev
Also, the natural sugar in fruit does affect your carbohydrate intake — especially if you eat a lot of fruit. This may temporarily raise your blood sugar or certain blood fats. However, this effect is lessened if you are losing weight. If you have diabetes or any other health conditions or concerns, work with your doctor to adjust the Mayo Clinic Diet for your situation. For example, people with diabetes should aim for more vegetables than fruits, if possible. It's a good idea to snack on vegetables, rather than snacking only on fruit.

Excess liquid calories add up just as food calories do. Beverages such as soda, fruit punch, beer, wine, dessert coffees and slushies all are calorie heavy and should be eliminated when trying to reduce your waist size. Water is a better option because it contains zero calories, hydrates the body and helps flush out toxins. Drink a glass right before your meals to reduce your appetite.

Make sure you work out the correct core muscles. Many core strength-building exercises focus on the oblique muscles, which run along the side of your stomach. Although working these muscles will give you a toned and flat stomach, it will also build up the muscle, making your waist appear wider than before. This is definitely not what you want when aiming for a tiny waist. To work your core and trim your waist you should focus on your transverse and rectus abdominals.
