I'm Starving!

It sounds like you've had a large carb load so far. Some people react to a big carb load with more hunger. Before throwing it all to the wind and binging, consider having a healthy portion of meat. It's worth a try to see if protein will calm down your hunger monster. Good luck.

You're mostly filling up on carbs, calorie dense satiety light. You'll need to experiment a bit but most people look to make protein a priority, it's good for muscle retention and good for satiety. A lot of people, myself included, reduce starchy carbs (not low carb, just fewer) so that those calories can be used for some fats and more filling veggies and fruit.

A smoothie would do absolutely zero to keep me full for longer than 5 minutes. Even a smoothie with protein powder would do much better. I love a bowl of porridge, others find that doesn't keep them full long and would rather eggs (boiled, scrambled, whatever!), Greek yoghurt, omelette etc.

And I also don't reach for fruit often at all really, other than maybe berries with some yoghurt for a pudding. It doesn't do much for me for the calories so I'd just rather not. Same for the Nutrigrain bar.

So experiment!

You should absolutely add more protein and fat! Boneless skinless chicken breast is great if you're worried about going over on calories. I love avocados for fat, also olive oil, and there's nothing wrong with good old butter in my opinion! Going forward, try adding more protein to your breakfast and lunch - eggs, Greek yogurt, protein powder are all good for breakfast and easy.

Have you set an aggressive weight loss goal? Calorie allowance seems a little low for your current weight?

Is your weight loss goal set to lose more than 1lb per week?

Eat smarter. Lean proteins, low calorie/multigrain breads, eggs, much more. Stay away from the pre-packaged high calorie bars and bagels and snacks. Think fresh vegetables, chicken, turkey, lean pork, lean beef, etc. I love bagels as much as the next person but rarely fit them into my calories for the day. Instead I eat lower calorie multigrain English muffins, Thomas makes some that are 100 calories each and taste great and help with fiber. The bread my wife and I buy is also a lower calorie 45/slice multigrain bread made by Sarah Lee. When you start adjusting what you eat you won't be starving so much. Also, add in some exercise to gain a few more calories.

As everyone else has said, get ye some protein & fat (& fiber). You've eaten pretty much only starch and sugar all day (assuming the smoothie wasn't a protein shake). If you really like the smoothie/food bar, you can perhaps sub in a protein shake and a Clif bar (or some other food bar with more protein).

It takes me 3 weeks of doing something extremely consistently for my body to adjust. If you are consistent and can get through the beginning, it will take less for you to feel full.

I agree with the less-empty carbs suggestions too.

Good luck!!!

I agree with the suggestions above-up your protein and healthy fats and work on reducing the carbs especially the refined ones like bagels

I can always tell the difference when I eat more carbs and less protein. I just restarted my journey and my daily goal is just under 1400 calories. I find that if I limit my carbs to about 100g a day and up my protein I'm OK. You would actually be surprised by how much food you can eat just by making a few tweaks. Ham and turkey breast slices have been life savers for me.

I'm with those wondering about that calorie goal. Look over your day and ask yourself a few questions. 1) Were you hungry all day, or just between lunch and supper? 2) Was there something that increased your stress which made you want to eat more? (wondering because you mentioned Big Mac, that's one of my go to for stress eating) 3) How much water or other liquids are you drinking during the day? Some people have found that their hunger signals are messed up and that drinking a glass of water helps with food cravings because they are actually thirsty. 4) Would you feel more full if you made some changes? Others mentioned proteins and fats. I look at my protein and fat goals as minimums, and fill in the rest with carbs. I also try to bulk my meals with lots of veggies. They are lower calorie, higher fibre, and have some great nutrients (depending on which veggie you chose). For the next couple days, consider increasing your calorie intake, and play around with some different foods to see if you can find something that helps you feel full longer.

Eat loads of veg. I had a soup with half a kilo of vegetables and it was only about 200cal. I was so full for hours. For breakfast I have oatmeal with fruit, it also keeps me really full. I snack on more fruit and veg and honestly sometimes I have to eat when I'm not even that hungry just to not eat too little calories. Seriously, veggies will be your saviour

You should absolutely not be starving. Eating too little can make your body go into starvation mode and store fat. For the rest the posts above have said enough - less carbs, more proteins and healthy fats. And water, lots and lots of water. Good luck!

After adding more calories, fat, and protein, know that sometimes you have hungry days. It happens sometimes.
