Will there be rapid weight loss with extreme calorie restriction (under 1000 a day) or will it slow the metabolism?

Yes and yes: Very low calorie diets do allow rapid weight loss. The decrease in metabolism is temporary and is the bodiy's attempt to compensate. Programs like medifast can help kickstart a weight loss effort and then transition to a healthy eating program, exercise, and regular support and encouragement/accountability.

How can I lose weight with non-insulin resistant hyperinsulinemia? Calorie restriction (with 40/30/30 macros) and exercise have had no effect.

See answer: It's very difficult to loose weight and in almost all cases most humans regain all the weigh back eventually. The body reacts to weight loss by slowing your metabolism severely. *Most remarkably, when you stop dieting your metabolism remains slow till you've regained all the weight back.

Roughly how many calories I should be consuming for weight loss?

Many factors!: It all depends on how much you weigh now, and on how active you are. If you eat 500 calories a day less than your body uses, you will shed a pound per week. Naturally, more activity helps because it helps you burn up more calories. Ask your doctor or ask for a referral to a nutritionist. Good luck on your weight loss.

Calories wt loss: How do you calculate calories for weight loss? ANS: calculate how many calories you are eating now. I recommend using the app FitnessPal. Do this 4 1 wk 2 c your current intake & calories burned. Then subtract 500 calories a day eat that level of calories or burn 500 calories a day more than you do now and weight should melt off. When you no longer are losing weight lower another 500 and repeat.

What is the difference between fat burn, calories burn and weight loss?

What is the difference between fat burn, calories burn and weight loss?

See below: Calories burned don't necessarily mean that fat is being burned, the calories burned could be coming from sugar, starch or protein, Weight loss can also occur from loss of muscle mass and not necessarily from fat loss. If the goal is weight loss by loss of fat, and retaining muscle, then the calories burned have to come mostly from fat.

What are some exercises that will burn calories fast for optimal weight loss?

Longer and harder: Gradually increase the intensity of your exercise by increasing the speed (walking or running) and add more weights to your weight lifts but you have to build it up slowly in order to build tolerance and avoid muscle injury. By doing too much too quickly, you can end up having very sore muscles. Take 2-3-4 weeks to increase the intensity of your work out.

What is the best amount to have a daily calorie deficit for optimum weight loss?

What is the best amount to have a daily calorie deficit for optimum weight loss?

500kcal: We recommend eating health & exercising regularly in such a manner as to achieve 500kcal daily deficit. Over a week, that should lead to 3, 500kcal loss or approximately 1 pound weight loss which is considered safe. Rather than try to achieve 10 pound loss over short period of time which is also nonsustainable, aim for slow but steady. Think tortoise, rather than hare. Marathon, not sprint.

Essentially, since weight loss is about calories in and calories out, why do cardio?

Essentially, since weight loss is about calories in and calories out, why do cardio?

If that were true: Then cardio helps to burn calories, so that would go towards the calories out half of the equation. Most nutritional medicine experts now say that muscle-toning/strengthening exercise is probably more effective than just cardio alone (i.e. Weight training 70-80% of your exercise and cardio 20-30%).
