A calorie isn’t always a calorie. Eating 100 calories of high fructose corn syrup, for example, can have a different effect on your body than eating 100 calories of broccoli. The trick for sustained weight loss is to ditch the foods that are packed with calories but don’t make you feel full (like candy) and replace them with foods that fill you up without being loaded with calories (like vegetables).
Forgive yourself. So you were going to have one cracker with spray cheese on it and the next thing you know the can's pumping air and the box is empty? Drink some water, brush your teeth, and move on. Everyone who's ever tried to lose weight has found it challenging. When you slip up, the best idea is to get right back on track and don't look back.
When the going gets tough (and it likely will from time to time along any weight loss journey), it’s important to realize that a host of non-food factors can make losing weight difficult, explains board-certified obesity medicine specialist Spencer Nadolsky, D.O., a diplomate of the American Board of Obesity Medicine and author of The Fat Loss Prescription. Hormones, genetics, and, ultimately, metabolism are three big ones, he says.
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.
