Choose a Low-Carb Diet
If you want to lose weight you should start by avoiding sugar and starch (like bread). This is an old idea: For 150 years or more there have been an infinite number of weight-loss diets based on eating less carbs. What’s new is that dozens of modern scientific studies have proven that, yes, low carb is the most effective way to lose weight.
Obviously it’s still possible to lose weight on 
any diet – just eat less calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
The main advantage of low carb diets is that they cause you to want to eat less. Even without counting calories most overweight people eat far fewer calories on low carb. Sugar and starch may increase your hunger, avoiding it may decrease your appetite to an adequate level. If your body wants to eat an appropriate number of calories you don’t need to bother counting them. Thus: Calories count, but you don’t need to count them.
A 2012 study also showed that people on a low carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually doing it.
Bottom line: A low carb diet reduces your hunger and makes it easier to eat less. And it might even increase your fat burning at rest. Study after study show that low carb is the smart way to lose weight and that it improves important health markers.
Cut Back on Sugars and Starches
The most important part is to cut back on sugars and starches (carbs).
These are the foods that stimulate secretion of insulin the most. If you didn’t know already, insulin is the main fat storage hormone in the body.
When insulin goes down, fat has an easier time getting out of the fat stores and the body starts burning fats instead of carbs.
Another benefit of lowering insulin is that your kidneys shed excess sodium and water out of your body, which reduces bloat and unnecessary water weight (1, 2).
It is not uncommon to lose up to 10 pounds (sometimes more) in the first week of eating this way, both body fat and water weight.
This is a graph from a study comparing low-carb and low-fat diets in overweight/obese women (3).
The low-carb group is eating until fullness, while the low-fat group is calorie restricted and hungry.
Cut the carbs, lower your insulin and you will start to eat less calories automatically and without hunger (4).
Put simply, lowering your insulin puts fat loss on “autopilot.”
Removing sugars and starches (carbs) from your diet will lower your insulin levels, kill your appetite and make you lose weight without hunger.
