Here are some tips from the article I wrote in my blog. If they don't help, you might look for food alergy/insulin resistence check ups, though they are super expensive.
Here are the Top 10 Ways to Lose Weight, Keep It off and Be Healthy in General
1. Avoid sugary and starchy foods. Starch is just complex sugar. Sugar, when it enters your bloodstream, soon turns into bodyfat. Blood sugar level spikes lead to insulin release. Insulin, in turn, transports the blood sugar to the fat deposits. This leads to a blood sugar level drop which means that you not only instantly gain fat, but become hungry again. A vicious cycle.
2. Eat green veggies. They are good antioxidants, plus they fill you up and are low in calories.
3. Eat good fats. The kind of fats found in Fish Oil, Omega-3's, are essential to you organism. Yet, our diet is practically devoid of these nutrients. This is a shame really, because the good fats in fish oil have many benefits. They aid in fatloss, help fight depression, improve skin condition, aid the function of the brain, prevent coronary desease and more. So take your fish oil capsules. At least 1 g a day is advisable.
4. Take your vitamin C's. 1 g a day is a good dosage.
5. Keep a food and workout log. Note how much food you ingest and how much exercise you do. Track your progress and adjust accordingly. If for example, after a certain two-week period you have stopped losing weight, either decrease your calorie intake, increase your activity level or do both. Make sure not to go too low on the calories, because this will eventually result in a weight loss stall. Instead, move more.
6. Do not drink anything that has calories in it. No soda pop, no fruit juice. Limit you alcohol consumption - these are empty extra calories. And no diet coke for that matter. The artificial sweeteners found in it send the same signals to your body as sugar.
7. Drink more water. Water is the main ingredient of your body. Drinking lots of water will make your body NOT hold excessive amount of water. Plus, water speeds up fatloss and is instrumental in the elimination of toxins.
8. Do some sort of cardio workout. You can do long distance running or walking, if these are your favorite forms of aerobic exercise, but some form of interval trainging, hill sprinting, jump rope, or a sport such as soccer, basketball, boxing or martial arts are much more effective. Anything that will make you huff and puff is good for you.
9. Weight train. Exercising your muscles while dieting will help you keep your lean body mass. This means a firmer, harder, less jiggly and more athletic physique. You can be 120 pounds and super soft by just starving yourself to this bodyweight or 125 pounds and actually thinner, wearing a smaller size jeans, with lean and hard legs and arms, thanks to weight training.
10. Increase your activity level. If you can sit instead of laying in bed, do it. If you can stand up, instead of sitting, do it. If you can walk around, instead of just standing, do it. Find ways to move more. Add yoga or streching sessions that will help you recover more and burn extra calories.
