There is a simple solution to this problem. Consume less sugar; drink less pop, drink more water/quality tea/quality coffee with no condiments, eat less cake, eat more vegetables, non-processed meats, salads, rice, etc. Above all, cook wholesome meals, skip the ready made meals especially the 0% fat stuff (sugar is the replacement to make it palatable). It's amazing what you can do in 15 minutes worth of cooking, even from scratch.

A favourite of mine right now is a 200g steak medallion cooked on the barbecue (post cracked pepper seasoning only) and a large portion of chopped Mediterranean vegetables (zucchini, eggplant, red bell pepper, red onion, spinach, green beans) fried with herbs de provence and olive oil. You could even replace the steak with diced chicken to cook in one pan. You can make sauté potatoes for more calories if you want. Great meal, manageable sugars, no preservatives.
