Any kind of "fad" diet is not going to help you, because you won't stick with it....... you need to figure out a healthy eating plan, based on the number of calories that right for you, along with a plan for moderate exercise...... all things that you should be able to stick with from now on.
A fad diet, is just that -- a fad; and if you do lose weight on it, as soon as you go off the so-called "diet", you will gain back all the weight, often, plus more...
chicken diet-so we try anyways. (boiled chicken with lemon grass, basil and salt for taste)
in my tradition, after giving birth, we go on a strict boiled chicken diet for a month. it's HARD as heck since boiled chicken is all you basically eat for an entire month, and you get tired of eating it, so you just fast basically. when i married my husband, i was 170. got pregnant, went to 200, had baby, went on the chicken diet, dropped to 160 in a month, afterwards, i stopped caring, jumped to 230, and remained at that weight for 3 years. got pregnant again, dropped to 200, and afterward gained back that 30lbs plus another 10.
4 years later, i'm at my lightest i've ever been the month AFTER i had my first born.
Don't try "dieting", because it usually is only temporary; lifestyle changes will do the most good for you. Keep in mind, that 5 months "post baby", your weight is not so bad; give yourself some time.
Don't compare yourself to your mother or even yourself when you met your husband; when I met my husband I was 18 yrs old and weighed a whole 90 pounds; today, I wouldn't even look good at that weight.......
That said: try to eliminate products made with refined sugar, flour and rice (simple carbs) and concentrate on lean protein and fiber (complex carbs), which includes lots of veggies, lean meats, low/no fat dairy, etc. While fruit is good for you (lots of vitamins/minerals) it has a lot of sugar, so make sure you eat whole fruit in order to get the fiber, rather than juices.... You should get at least 5 servings of fruit/veggies per day; it's recommended that at least 3 of those be high fiber veggies and 2 fruit....... try to stick with apples, pears, etc.... again, lots of filling fiber, without a lot calories.......
