How low are your carbs going and What kinds of carbs? It has a huge difference. Its hard to say without knowing what your eating & how much. Carbs & Protein have 4 calories per gram while fat is over twice that at 9. (Alcohol is 7 empty calories if i recall)
Nuts are amazingly calorie dense. Its quite easy to eat say a few handfuls of almonds and be close to 1000 calories without even realizing it. (handful +/- is 200 calories?)
A handful of granola, especially store bought, has tons of carbs(sugars!)/calories in a small handful. Wheres as broccoli is more or less the opposite. The carbs from granola will also spike your insulin MUCH more than the broccoli would, if at all.
Different cheeses can be highly variable as well.
Your eating should be more stable on a fat based diet vs carbs as well. As fat should be more filling. If your used to eating incredibly high carbs your body will crave them for awhile.
Eggs are an AMAZING source of protein/fats. Try to get free range, at least omega-3/6 fed etc. Also not sure about margarine? But actual grass fed FULL fat butter is amazing. I love it on my eggs & can never go back.
You might need to slowly lower the carb/fat ratio? Try to do morning runs/hikes/etc fasted if possible as well.
A typical day for me is:
String cheese(surprising good/portable. 1 carb, 6/6 pro/fat)
Actual heavy cream powder from a farm/no additives in coffee(amazing stuff)
walnuts(30g) (180 cal!)
almonds(30g) (200 cal!)
16G of Adams natural peanut butter(peanuts+salt)
low carb tortilla(6 net carbs)
Salad with mixed greens. small amount of HIGH fat dressing
turkey/chicken with above
170g of broccoli/cauliflower/carrots
52g hummus of some kind
350-400g of some mixed veggies
turkey/chicken/steak with above
casein protein powder or 3 eggs
Might throw in some full fat pepperoni or extra cheese on eggs at night depending if it was a long run that day, etc. Maybe cook bacon once a month and portion that out… depends!
The day I pulled the above from had the totals below
75g carb – 32 fiber
During a Base week where I’m going 25-28+ miles a week for around 4,000 calories avg daily. I’ll more or less throw in some sort of cheat meal AFTER my big hike or throw in an extra egg and/or cheese on that egg on the day of a 2 hour run/walk/deal!
Hope that helps some!
