Is a calorie truly a calorie? Not always, because different types of calories can affect your body and your results differently. Dietary fat, for example, is more "fattening" than protein or carbs because it's less likely to be used to build your body. Granted, carbs can potentially make you fat, but they also directly fuel your training. Protein? That's a no-brainer: It builds muscle. Fat does neither, but it isn't useless; moderate amounts of it support vitamin absorption and help manufacture hormones.
Dietary fats are essential molecules that cannot be ignored in a fat loss plan because of the important roles they play in many different bodily processes. Fat is the most energy dense nutrient. Whereas protein and carbs both contain 4 calories per gram, fat contains 9 calories per gram. The downside to fat is that it is easily stored as adipose tissue (fat).
One of the very first cardio exercises to reduce belly fat is walking. Surprised? Do you think it’s too simple to be effective? Well, then you should know that walking is a great and effective way to burn away that ugly belly fat. In fact, it is an excellent fat burner for your entire body. If you follow a healthy diet along with walking at a steady pace for 30-45 minutes for at least four to five days every week, you will witness a gradual decrease in your weight.
This kind of strength training recruits fast-twitch muscle fibers, which increases fat burning, says Shore. Although you could see a small increase in the scale as you build muscle, keep in mind that muscle is more dense than fat. That means it’s very likely that you're losing fat while gaining muscle, so don’t stress, says Shore. To keep up your progress, aim to increase the amount of resistance you use when your current weight becomes too easy to lift, says Shore.
Skimp on fluids, and your body will release an antidiuretic hormone that leads to water retention that could affect the scale, Dr. Setlzer says. While this sneaky effect is one reason why the scale is a poor measure of body mass loss, you can outsmart it by drinking more—particularly if you fill your glass with water or non-calorie alternatives like unsweetened coffee and tea.
This may explain why the fat-burning effects of eating more protein were confirmed in a study published in the American Journal of Physiology. One group was fed a high-protein diet (just over 1 gram per pound of body weight per day) while the second group consumed an amount closer to the lower recommendation of the RDA (recommended dietary allowance). The group eating the higher-protein diet burned the most fat.
