When you want something sweet, all those fat-free, sugar-free options seem like a smart choice for weight loss. But researchers at Cornell University found that overweight people who choose low-fat versions of snack foods rather than the regular kinds consume, on average, twice as many calories. "The terms 'fat-free' or 'sugar-free' can create a green light effect, triggering people to eat more," says dietitian Cynthia Sass, RD. But many fat-free foods have about the same number of calories (or more) as their full-fat counterparts.
Figure out how many calories you should eat each day to lose weight. Losing weight isn't all about weight. The more aware you are of the calories in the food you eat, the more easily you'll be able to eat the right amount of food and do the right amount of exercise to drop a couple of pounds. Take your food journal and look up each item individually. Keep a running tally and add up your calorie total for the day.
Ketones (beta-hydroxybutyrate [BOHB] and acetoacetate [AcAc]) are produced by the liver when both serum insulin and liver glycogen levels are low (McGarry 1973). They can be made from fat stored in the liver, from fat released from body adipose reserves and delivered via the bloodstream; or they can be made from dietary fat entering the bloodstream after digestion and absorption as chylomicrons. In other words, once fat is in the body as adipose reserves or absorbed dietary fat, liver ketone production is a function of blood insulin and liver glycogen content. There is no special relationship between mobilization of body fat stores (i.e., weight loss) and blood ketone levels.
