Carbohydrate especially highly refined sugar, is like a drug, it stimulates feelings of well-being.
As a general rule do not drink your calories. This means no soft drink, hard drinks, beer, triple-bock Latte’s with whipped cream, sugary foo-foo drinks. Even Milk is 150 calories a cup.
What worked for me, is intermittent fasting, also known as time restricted eating. You need to talk to your doctor before starting something like this, esp. if you are diabetic or taking certain medications. etc. But most people eat far too much, far too often, and not the right kind of foods.
Exercise for fat loss is kind of a red herring, you simply cannot outrun your diet. A healthy spoonfull of peanut butter will take an hour of moderate exercise to burn off.
The only way is calorie restriction. Get yourself an inexpensive gram scale and start weighing out portions. I used to believe the “Nutrition Facts” labels on all our foods was silly and a waste of time. Not any longer, they are very useful. Eventually you will memorize carb, fat, and protein percentages for the most common foods and portions.
What you want to do is find foods that are both filling and nutritious, and don’t spike glucose levels. What I like about intermittent fasting is having large, satisfying meals of foods I like. Mixed nuts, eggs, cheese, high quality protein foods that are high on “satiety”. Junk foods high in carbs spike glucose or blood sugar very high, and then inevitably crash, setting up for the next round of “hunger pangs”, meaning the trigger to consume MORE carbohydrate.
You’ll soon figure out your personal basal metabolic rate - how many calories are necessary just to exist, basically, as a completely sedentary individual. It is a little distressing to discover just how few calories that is. But armed with this knowledge you’ll figure out how to reduce at a sustainable rate. Keep in mind you have to make permanent changes to your food choices, or at least the amounts, or you will put all the fat back on, and then some.
