Meal Replacement Shakes

Your calorie need depends on your gender, height, weight, age, and activity level. A good weekly loss, assuming you have excess fat, is around 1% of your body weight. Trying to lose faster, or aiming for a too low body weight, or not getting in good nutrition (despite eating enough, or even too many, calories), will make you starve. If you eat enough, quality and quantity, you're not starving. Hungry is not the same as starving. You are not supposed to feel full all the time, even though the diet industry and the food industry insist that even the slightest feeling of hunger is an emergency. You are supposed to get hungry before meals, and then be satisfied from that meal, and repeat, forever.

If you are overweight, you have made overeating a habit. To lose weight and maintain your loss, you have to change that habit. You can't just change a habit without changing the preference for that habit, and to change preference, you need to feel confident that you aren't hurting yourself by sticking to the new habit. This takes time and practice.

You can eat anything you want and lose weight. A wide variety of foods is the easiest way for most people to get in sufficient nutrition without too many calories, and to avoid the kind of boredom that triggers overeating.

Meal replacement shakes are developed to take money from the desperate and ignorant. Don't be desperate and ignorant. Educate yourself.
