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.
• If you’re in a caloric deficit: you’ll be better off choosing foods that are low in energy density and high in nutrient density. These foods will help keep you full when calories are low. Energy-dense foods like cereal, chocolate bars, ice cream, Pop-Tarts, etc. are less filling and thus less satiating. This is why you can eat a chocolate bar and be hungry again ten minutes later, while a [calorically] comparable meal filled with protein and veggies will keep you fuller for longer.
"Crash diets (dramatically cutting down how much you eat) might help you to lose a few pounds at first, but they’re hard to sustain and won’t help you keep the weight off. It might seem like a quick and easy option, but eating too few calories can actually do more harm than good. If your calorie intake dips too low, your body could go into starvation mode. This will slow down your metabolism, making it harder for your body to lose weight. Make sensible, healthy changes to your lifestyle that you can stick to and avoid the fad diets."
Set up a box behind you and then lower your body until your glutes touch it. Touching the box requires you to “sit back” as you squat, as if you were lowering yourself into a chair, and this action gets the glutes and hamstrings maximally involved in the lift. It also helps you to perfect your squat form. You can start with a higher box and gradually move to smaller boxes as you improve, ultimately training your body to squat below parallel with no box at all. Better still, the box squat places no strain on the knees, so even people with knee problems can attempt it safely.
