The conclusion? Intermittent fasting was just as effective for weight loss as daily calorie restriction. So if you struggle with daily food restriction, fasting might be an easier way to dial back the amount you’re eating without feeling completely deprived. Read more in-depth about how intermittent fasting works (and if you’ll be able to stick to it) here.
After having 3 kids (6,4,2) I have been unable to effectively lose the belly fat, hip fat, and leg fat that I gained throughout those pregnancies. I had resigned myself to never being able to look at my legs from the back in the mirror again - it disgusted me so much. But now - I can happily look at my backside in the mirror! I never thought it possible! I had success with weight loss doing the Whole 30 and that really helped me to eat much better and determine some intolerances, but never have I seen the drastic fat loss changes in my body in such a short amount of time. I have dropped 2 sizes in pants - the shorts I bought at the beginning of the summer look like clown clothes on me and I will have to give them away.
“Poor sleep quality or quantity can make it difficult to lose or even maintain your weight,” says Darria Long Gillespie, MD, a clinical assistant professor of emergency medicine at The University of Tennessee. When you are sleep deprived, your body becomes less sensitive to the effects of leptin, the hormone that usually signals that you’ve had enough to eat. At the same time, the amount of the hunger hormone, ghrelin, increases, so you want to eat more. Together, it’s a recipe for overeating.
Fat acids are a substrate for cholesterol, meaning that fatty acids must be available to create cholesterol. This is important because cholesterol is eventually converted to testosterone. If fat intake is too low there will not be enough fatty acids available for optimal testosterone productions. This will lead to an even lower level of testosterone.
Eating meals frequently helps combat fat gain by giving your body long-lasting energy and preventing intense hunger that leads to irrational food choices and over eating, says Armul. At each meal, fill half of your plate with fruits and veggies, one quarter with whole grains, and one quarter with lean protein, like beans, nuts, eggs, fish, and poultry, she says. These nutrient-rich foods increase satiety by slowing the digestion and absorption of food in the stomach, which ultimately leads to less calories consumed and more weight loss.
6. Fast once a week: While regularly underfeeding your body completely messes with your hormone balance, there’s sufficient research to suggest that intermittent fasting (IF)—or going without any food for set intervals—can actually help your insulin sensitivity and burn more fat. Researchers at LSU, for example, found that when people fasted all day, every other day, their fat oxidation increased and they actually lost 4 percent of their body fat in just 22 days. There are a lot of ways to go about IF, from fasting for 12 to 16 hours every day, to going 24 hours once a week. (Learn more about it here.)
Another misconception about HIIT is that it will cause muscle loss. This is just not true either. This myth got started because a higher amount of calories burned during HIIT will come from stored amino acids (muscle tissue) when compared to lower intensity cardio. As long as HIIT sessions are kept to a short duration muscle loss not be a problem. In fact, muscle growth and muscle retention are increased due to the effects HIIT has on anabolic hormones. Just one 10-15 minute session of HIIT can increase testosterone and growth hormone levels for hours after the workout has ended.
REALITY: Bro-scientists will insist that eating small portions every 2-3 hours will increase your metabolism. They base this on the thermic effect of food (TEF), which refers to the energy (calorie) cost of your body processing the food you consume. On average, 15 percent of the calories you consume are burned by processing them (although the rate varies by macronutrient). Someone took this idea and assumed that the more frequently people consume their meals, the more frequent TEF will take effect and thus increase fat oxidation.
Carbohydrates are extremely important to training since they are the primary fuel source for working muscles. During weight training the body uses ATP for energy. ATP is replenished through something called the glycolytic pathway. This pathway converts glucose into ATP. Glucose (carbohydrate) is obtained from the bloodstream or from carbs stored in the muscle tissue as glycogen.
If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.
When it comes to the rate at which progress can be made fat loss is far different from muscle growth. Whereas building muscle is a slow process, fat loss can take place at a pretty rapid pace. We have all seen the commercials that promise to help you lose 10-20 lbs. in a few weeks. While it is entirely possible to lose huge amounts of weight in short periods of time, this is not what we are aiming for.
The easiest way to cut calories? Eliminate excess dietary fat—meaning no butter, oils, or salad dressings (low-fat or fat-free dressings are OK); remove the skin from chicken; substitute egg whites for most of your whole eggs; avoid whole-milk dairy products; and ditch marbled red meats such as rib-eye for lean cuts such as flank. Keep some healthy fats in your diet, such as salmon, mixed nuts, peanut butter, and avocados.
Seedman recommends eating at least 1.5 to 2 grams of protein per pound of body weight, and scoring it from quality sources like lean meats, eggs, fish, and protein powders. And when in doubt, eat more protein. “Of all the macronutrients to overdo it on, protein is it because excessive amounts are more difficult for your body to turn into fat compared to carbs or fat,” he adds.
