tablets ,they would be making billions and billions of dollars. obesity is major problem everywhere now since you have not mentioned anything about your height and weight i will give you some general guide lines to lose weight
diet contributes around 70 percent in weight reduction , and only 30 percent is by exercise.
so reducing calorie intake should be your main concern and also exercise
your daily calorie intake should be (your height in cms) - 100 x20 equals your caloric intake daily.
now 40 percent of the total kcal you should consume for breakfast, then 30 percent for lunch and dinner.
now if you check the internet and search for calorie chart you will find a table by using which you yourself can calculate your diet chart ,just do not cross the calorie i have mentioned for each meal.
