I truly believe in it’s all about calories in calories out to lose fat , but what’s up with guys like Vince Del Monte saying its not all about calories in calories out and saying hormones is what dictates fat loss. And then there are people claiming spiking your insulin on a calore deficit causes you to not lose fat even though your on a calorie deficit. Explain to me your reasoning on how this information is false on what these people are claiming.
“I tell all of my celebrity and professional-athlete clients to get between 6 and 8 hours of sleep per night. Everyone is overly focused on food, water and exercise, all of which are extremely imperative to weight loss and optimal health. However, without proper sleep, all of these the other factors are null and void. When you don’t get enough sleep, levels of the hormone leptin drop, which increases appetite. This surge in appetite makes comfort food more appealing, which can derail weight loss efforts.” — Jay Cardiello, celebrity fitness and nutrition expert
Weight loss is a mathematical equation: you simply need to take in fewer calories (of whatever you prefer to eat) than you use each day. So, yes, you could still lose weight. That said, you won't be a healthy "thin" if you don't nourish your body with good, whole foods, including plenty of fresh fruits and vegetables. Plus, fruits and veggies aid in weight loss by helping you to feel full (taking up the space in your stomach you might be tempted to devote to less healthy options).
What’s your take on Gary Taubes’ work (if you’ve read it)? He hates the calorie in/out concept but from reading it that’s mainly because it doesn’t address causality (and he doesn’t believe everybody that’s obese/overweight is just lazy/stupid). As I understand it he specifically he says insulin levels regulate how easily fat is stored and available to be burned off and affects how hungry we get. Is that wrong?
I mean, people lose fat on low carb diets, low fat diets, paleo diets, vegan diets, raw food diets, diets that involve eating “clean” instead of “dirty” or not eating after a certain time at night, and countless other types of diets that involve every gimmick, fad and method you can think of except the specific task of creating a caloric deficit. But yet, they have all caused people to successfully lose fat.
Snacking can be a gray area for weight loss. Really think about whether a snack is necessary before eating it. A low-calorie snack can be a good option before or after a work out or if you're feeling very hungry and there's more than two hours until your next meal.[11] To keep your metabolism moving and keep yourself full, you should be eating every three to four hours. That might mean multiple small meals or three meals with snacks in between.
One easy trick if you're a pasta fan is to swap out white pasta for the wonderfully named courgetti (spaghetti made from spiralizing courgette). You’ll hardly notice the difference when you’re eating it, but you’ll be fuller for longer despite consuming fewer calories. When you consume fewer calories, your body can go to your fat reserves for energy, rather than just burning off the food you’ve eaten.  
Couldn’t agree more with this article from first hand experience. The fitness industry is sooo full of misinformation intentional or not that something this basic has got lost on us. I’ve lost 50 lbs by finally watching the calories. I have done no cardio at all, but do weight lifting/resistance training several times a week to maintain muscle. I’ve even fasted a few days to break a few short plateaus for 24-30 hours. I’m a few short weeks from the ever elusive 6 pack abs (personal challenge), and was never even close when i tried other methods of weight loss. My two cents, cut from BMR, use no activity factor multipliers. If you have fat on your body, 1000 calories is not too low. As you get leaner, start slowly adding back in the calories to BMR maintenance so you dont regain. Eat WHATEVER you want but at the end of the day, make sure you are in a deficit. (Literally even the junk food if you need to. Just remember, the junk foods are high in calories and the healthier ones are more nutrient based. From a fat loss perspective your body doesnt care if its grilled chicken or pizza. But if you do eat low nutrient food, take a multivitamin.) Use any online BMR calculator and cut from there. Measure, measure measure your body to track progress. Starvation mode? Holy cow, what a joke! When’s the last time you saw a obese person die of starvation? Ask for their studies. They dont have them. You dont need to worry about starvation mode until youre in single digit body fat, and if you’re reading this, you probably aren’t. You wont lose muscle either if youre doing enough weight training to maintain. 30 minutes. Forget cardio, it will only make you more hungry and less mobile the rest of the day. Cutting is not fun, but its temporary. Good luck to everyone! Thank you for writing this article.
“A study by David Jenkins, MD, PhD—the University of Toronto pioneer in low-glycemic eating — demonstrates that eating small portions at frequent intervals is good for your health in a number of remarkable ways. Within the study, they found that people who ate every three hours reduced their blood cholesterol by over 15% and their blood insulin by almost 28%. That’s key, because in addition to regulating your blood sugar level, insulin plays a pivotal role in fat metabolism, inflammation and the progression to metabolic syndrome. When your body produces less insulin, you’re much less likely to convert dietary calories into body fat.

"Protein is great for fat loss. It helps build and preserve lean muscle tissue and can increase the amount of calories you burn. It’s also a great source of energy that helps you feel fuller for longer, so you’re less tempted to snack. Good sources include chicken breast, tuna, eggs, milk and chickpeas. And if you’re finding it difficult to avoid snacks that are high in carbohydrates, try substituting them for protein shakes or bars. Remember also to opt for the lean sources of protein because some sources can be high in saturated fat."


Miller and his colleagues reviewed 25 years' worth of weight loss research and found that, during a typical 15-week weight loss program, people lost, on average, 23 lbs. (10.4 kg) by only dieting and 24 lbs. (10.9 kg) by dieting and exercising, they reported in 1997. That difference may seem small, but after one year, the people who only dieted kept off 14 lbs. (6.4 kg), on average, whereas those who dieted and exercised kept off 19 lbs. (8.6 kg). [2016 Best Heart Rate Monitor Watches]
Nuts. It’s very easy to eat until the nuts are gone, regardless of how full you are. A tip: According to science, salted nuts are harder to stop eating than unsalted nuts. Salted nuts tempt you to more overeating. Good to know. Another tip: Avoid bringing the entire bag to the couch, preferably choose a small bowl instead. I often eat all the nuts in front of me, whether I’m hungry or not.
